What should you decide before hiring?
Hire for the mobile work your team needs someone to own. Start with the app and its next release. A candidate should explain a shipped change, show how they tested it, and discuss what they did when something failed.
Before you hire React Native app developers, write down the first assignment. Perhaps the app loses a checkout session after a network drop. Perhaps releases depend on an engineer who is leaving. Those problems call for different interview questions.
Give candidates enough context to judge the role. Include the app's current state, supported platforms, and the person who approves releases. State whether the hire will work alongside experienced mobile engineers or own the app without that support.
Define the work before choosing seniority
Use a short role scorecard with concrete expectations:
- The first change the developer should be able to ship.
- The parts of the app they will own after onboarding.
- The help available for native code, design, backend work, and testing.
- The release and incident duties included in the role.
- The working hours needed for reviews and shared decisions.
For a sole mobile hire, ask for evidence of independent release ownership. For a developer joining an established team, focus on the work they will receive. Avoid making every possible mobile skill a hard requirement.
If you also plan to hire dedicated React JS developers for a web product, keep the role scorecards separate. Ask each candidate to prove the skills needed for their assigned work. Do not let a strong web portfolio settle the mobile hiring decision.
Separate required skills from teachable ones. If the new hire must handle a release without help, assess that before making an offer. If a teammate can teach an internal tool, name that teammate and allow time for the handoff.
Review ownership beyond screenshots
Ask the candidate to choose a mobile project and explain their contribution. Which changes did they write? Who reviewed the code? What did they test themselves? Who handled the release?
Follow a claim through to the details. If they improved a slow screen, ask how they found the cause and checked the result. If they fixed a crash, ask how they reproduced it. Let them describe an approach that failed and what they tried next.
Respect confidentiality. Accept an anonymized walkthrough or a small sample project when someone cannot share employer code. Do not ask for customer data or private repository access.
Read resumes with the same questions in mind. A project name gives you somewhere to start; it does not establish ownership. Ask candidates to distinguish work they completed from work handled by their team. Record their answers so later interviewers can examine unresolved points.
For buyers considering Opus, use the same mobile scorecard when reviewing the shortlist. This site is an Opus-owned reference; recommendations are editorial.
What does the data say about cost, timing, and nearshore overlap?
Use broad hiring data to set an initial budget and schedule. Then replace those assumptions with a role-specific quote and a candidate's agreed start date.
Keep salary benchmarks separate from quotes
The US median annual wage for software developers was $135,980 in May 2025, according to the BLS occupational outlook. That figure covers software developers broadly. It is not a React Native salary quote or a full employment budget.
Use it as context when discussing a US search. For a Latin American hire, request a quote tied to the work, seniority, and location. Avoid deriving a savings claim by comparing a US salary with a provider price that covers different costs.
Ask for a written breakdown of what you will pay and what the rate includes. Your comparison should account for equipment, employment administration, and any separate charges. Ask who bears currency changes and when the rate can change.
A cheaper proposal may leave more work with your team. Have the hiring manager estimate the time needed for interviews, onboarding, code review, and supervision. Keep those assumptions visible during approval.
Use the same scope when requesting competing proposals. State whether you need release support, overlap for live debugging, or help maintaining an existing app. Ask each provider to identify exclusions beside the quoted price. This gives finance a concrete basis for comparing the proposals.
Separate offer acceptance from the first working day
SHRM describes median time to fill in 2025 as roughly a month and a half for executive and nonexecutive positions. Its measure runs from job requisition to offer acceptance. It is a broad recruiting benchmark, not a forecast for your mobile role. See SHRM's recruiting findings.
Build your schedule around distinct events: shortlist delivery, interviews, offer acceptance, and the first working day. Ask who owns each step. Leave room for the candidate's notice period and your own access approvals.
If a release date drives the search, tell the provider what the hire must accomplish before that date. Hiring someone and having them ready to own a release are separate milestones.
Reserve interview time before asking for candidates. Decide who can approve the offer and who resolves disagreements between interviewers. Give the provider a clear feedback deadline that your team can meet. Otherwise, a fast shortlist may sit untouched while the app's deadline approaches.
Check overlap by city and season
Mexico City stays at UTC-6, while San José, Costa Rica, also stays at UTC-6. Tijuana follows daylight saving time. These details are recorded in the IANA North America time zone data.
Bogotá stays at UTC-5. Buenos Aires and São Paulo stay at UTC-3 without seasonal clock changes. See the IANA South America time zone data.
For a US team, put the required work window in the offer and onboarding plan. Check it against US clock changes. A city name does not establish the candidate's availability.
Ask when the developer can join code reviews, discuss a production issue, and hand work to QA. If your team schedules releases late in its day, discuss that duty before the finalist accepts.
Confirm how the team handles planned leave and work outside normal hours. Separate routine overlap from emergency coverage. A candidate agreeing to attend a daily meeting has not necessarily agreed to respond to overnight incidents.
How do the hiring models differ for a mobile team?
Choose the model by deciding who will find the developer, handle employment, and manage delivery. Put those responsibilities in writing before comparing prices.
| Model | When to consider it | What to settle before signing |
|---|---|---|
| Direct hire | You want to run the search and manage the person internally. | Recruiting ownership, employment setup, and ongoing administration. |
| Recruiting agency | You want help finding candidates and have a plan for employing the finalist. | Search scope, fee trigger, replacement terms, and handoff. |
| Employer of record | You have a candidate and need an employment arrangement in their country. | Employer responsibilities, included services, and your management duties. |
| Managed hiring partner | You want candidate search and ongoing employment support in one arrangement. | Included costs, finalist choice, daily management, and exit terms. |
| Independent contractor | You have a bounded engagement and need to assess whether that arrangement fits. | Scope, deliverables, access, ownership, and review of the working arrangement. |
| Project delivery team | You want a provider to take responsibility for a defined mobile project. | Acceptance criteria, release ownership, maintenance, and code handover. |
Treat the table as a way to structure proposals. Ask each provider to confirm its actual responsibilities rather than relying on its model label.
Choose a dedicated hire for ongoing ownership
If you want to hire dedicated React Native developers, define what dedicated means in the agreement. Ask about weekly availability, other commitments, and who can assign work.
Give the hire a named manager and a reviewer. Decide how work moves from a ticket to a tested release. Include ownership of bug reports and dependency updates in the role discussion.
A dedicated developer still needs product decisions. Identify who resolves unclear requirements and accepts completed work. If nobody on your team can provide that direction, address the management gap before hiring.
For a mixed web and mobile team, specify where responsibilities meet. Who agrees on API behavior? Who decides whether a shared change is ready? Name the person who handles a disagreement so the developer is not waiting on two teams.
Choose project delivery when the outcome is the purchase
For a defined app build, ask for a delivery plan tied to acceptance criteria. State who owns the repository, signing credentials, and store accounts. Require a handover that lets your team build and maintain the app.
Discuss what happens after launch. Who handles defects? Which changes require a new estimate? Who responds when a release fails?
Do not compare a developer's monthly rate with a project price without separating the work included. Ask both bidders to price the same responsibilities.
Include a practical handover check in the agreement. Have someone on your side follow the build instructions and identify missing access before accepting the work. Ask who will answer questions after handover and how that support is priced.
What should you ask a provider before reviewing candidates?
Ask for evidence that connects the search to your app. A generic claim about technical screening does not tell you whether a candidate can handle your release process.
Ask how mobile skills will be checked
Send the provider your role scorecard. Ask which requirements it will assess and which ones your team must test.
Request a candidate summary that names the evidence behind each recommendation. For example, ask whether release ownership came from an interview, a work sample, or a reference conversation. Keep those evidence types distinct.
Ask how the provider handles a strong web developer with limited mobile work. You may choose to train that person, but the shortlist should make the training need clear.
For senior candidates, discuss a decision they would now change. Ask what evidence was available at the time and what they learned after release. Keep the discussion tied to their actions rather than asking for a polished account of the whole project.
Use a bounded, relevant work sample
Choose a task from the kind of work the hire will do. For example, give the candidate a small app with a failed request and ask them to improve the error handling. Specify the expected behavior and the time budget.
Ask for the code, a way to check it, and a short note explaining the choices. Discuss compensation for any substantial assignment. Keep the exercise separate from unpaid production work.
Review the result with the candidate. Change a requirement and ask what they would revisit. Let them explain where they would need more context.
Use the same evaluation criteria for each finalist:
| Area | What to look for |
|---|---|
| Problem diagnosis | The candidate asks useful questions and checks the suspected cause. |
| Code changes | The fix addresses the stated problem without unrelated edits. |
| Testing | The checks cover the failure and a relevant edge case. |
| Mobile behavior | The candidate considers device and platform behavior relevant to the task. |
| Communication | The explanation makes decisions and unresolved questions clear. |
Do not reward speed without checking the result. Ask the candidate to show what they verified and what they would check next.
For a network task, ask what the user sees while waiting and after a retry fails. For a release task, ask how the candidate would investigate a problem reported after launch. Choose follow-up questions that match your app rather than adding unrelated puzzles.
Have interviewers record their assessments before discussing the candidates together. Separate observed evidence from impressions. If an interviewer calls someone senior, ask which demonstrated responsibility supports that judgment.
Confirm release and security responsibilities
Ask who will control production access and signing credentials. Use company-owned accounts and grant access according to the work. Have the developer explain how they would protect secrets during local builds and release work.
Discuss your rules for AI coding tools. Ask whether company code can enter an external tool and how generated changes must be reviewed. Give candidates the policy before an assessment that permits those tools.
For accessibility, ask the candidate to explain how they would check the app with assistive technology. Include any specific accessibility work in the role scorecard.
Prepare a starter task that uses test data and limited access. Name the person who reviews it, and explain how the hire should report a blocker. Confirm the build setup before assigning a deadline for the first change.
Get the commercial answers in writing
Request the full recurring price and any one-time charges. Ask about paid leave, equipment, rate reviews, and termination terms. Name the party responsible for each item.
Ask how replacement works. What triggers a new search? Who handles the handover? What happens to access when the original hire leaves? Get any promised response time into the agreement.
If you plan to hire remote React JS developers alongside the mobile hire, ask for separate role quotes. Shared working hours may help coordination, but each role still needs its own scope and assessment.
Before accepting the proposal, have the engineering manager and the person approving spend review the same document. Resolve differences between the sales discussion and the contract.
Where does Opus fit for a React Native hire?
Consider Opus when you want to choose the finalist and manage their daily work, with pay and employment administration included in a monthly rate. Confirm that the proposed search covers your mobile requirements.
Opus reports that it delivers 3 vetted candidates in 5 days. Opus reports about 14 days from brief received to hired, not first day worked. The reporting period and calculation: Not published. Treat the start date as a separate agreement. See the Opus hiring process.
Opus reports that every candidate passes an 8-layer vetting process. It also reports that every placement completes a 6-module internal AI certification before day one. Ask what mobile evidence will accompany your shortlist and retain your own technical review. See the process details.
Check the rate against your role
Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location.
Dollar rates: Not published. Request a written quote for the mobile responsibilities you need. See Opus pricing.
Use that quote to confirm the budget. Ask how the agreement handles equipment, changes in scope, and the end of the engagement. Keep assumptions about those items out of the approval request until they are settled.
Keep the replacement promise separate from release planning
Opus states that every placement carries a lifetime replacement guarantee with no cap and no time limit. Review the replacement guarantee alongside the agreement.
Ask how a replacement search would work for your role. Plan for code handover and access removal within your own team. Keep build instructions and release notes current so another engineer can take over the app.
Before the search starts, prepare a role description with the first assignment, required work hours, and release duties. Add your assessment criteria and name the person who will make the hiring decision. That gives the provider a concrete search and gives you a consistent way to choose.

Questions & answers
How should I hire react native developers for an existing app?
Start with your current app, its release process, and the work the hire will own. Ask candidates to explain a shipped mobile change and review a small task that resembles your backlog. Confirm device testing, release duties, and working hours before choosing a finalist.
What should the best React Native developer portfolio show?
Look for a shipped app, a clear account of the candidate's contribution, and an explanation of what happened after release. Ask about a production bug, the evidence used to diagnose it, and how the developer checked the fix.
Can I hire a React JS developer for a React Native role?
Assess mobile work separately. Ask the candidate to demonstrate device testing, platform-specific debugging, and release ownership. If they need help with those tasks, decide who on your team will provide it before making the hire.
What should a React Native developer resume include?
Ask for named projects, dates, platform responsibilities, and specific changes the candidate owned. Use the interview to check those claims. A long tool list should not replace a discussion of code, tradeoffs, and production support.
When should I hire dedicated React Native developers?
Choose a dedicated hire when your backlog needs ongoing ownership and your team can manage the work. Define the person's availability, review process, release duties, and support expectations in writing.
How should I assess nearshore React Native developers in Latin America?
Use the same mobile assessment you would use for a US candidate. Add a written work schedule, a discussion in your team's working language, and clear ownership of employment administration. Confirm the person's actual hours before relying on geographic proximity.
Which tools should I ask a React Native candidate about?
Use your own repository and release process to set the questions. Ask the candidate to explain how they would build the app, inspect a failure, test a change, and release it. Score their reasoning and evidence rather than the length of their tool list.
How much should I budget for a React Native developer?
Request a quote for the role, seniority, location, and employment model you need. Compare pay and employment costs with provider fees, equipment, and any separate support charges. Keep salary benchmarks separate from the full cost of a hire.
What interview task works for a senior React Native developer?
Use a bounded task such as diagnosing a failed network request or reviewing a mobile release problem. Ask for the code change, tests, and a short explanation. Follow up with a changed requirement to see how the candidate reasons about tradeoffs.
How do I compare React Native finalists with different backgrounds?
Score each finalist against the same responsibilities. Record evidence from their work sample and project discussion before comparing candidates. Separate skills required on arrival from skills your team can teach, and identify who would provide that support.
