How to Hire React Native Developers: A Buyer’s Guide

Hire for the Mobile Work You Actually Need

A React Native developer should be able to take a useful feature from requirements to a tested iOS and Android release. React knowledge matters, but a production app also needs native integrations, device testing, release operations and someone responsible for maintenance.

For a CTO, Head of Product or engineering leader, the hiring decision starts with the gap in your team. Do you need an engineer who joins an established delivery process, or a partner who can own a defined mobile workstream? Our React Native development service covers building and improving mobile apps, including native integrations and ongoing delivery.

If you have not yet chosen between React Native and platform-specific development, first compare the approaches on our mobile app development page . Hiring against an assumed stack before validating the critical requirements can create avoidable rework.

Write a Brief Before You Compare Candidates

Give every candidate or supplier the same short brief. It should describe the first useful outcome, the constraints and who will work alongside them. For an existing app, include the current versions, build process and known problems; a feature estimate without that context may hide substantial setup or upgrade work.

• Product outcome: the user, the workflow and what must work in the first release.

• Platforms: supported iOS and Android devices, accessibility expectations and any tablet requirements.

• Integrations: authentication, payments, notifications, analytics, hardware or third-party SDKs.

• Starting point: designs, backend APIs, repository access, existing tests and release documentation.

• Team responsibilities: who provides product decisions, design, backend development, testing and release approval.

• Commercial constraints: budget range, target date, dependencies, exclusions and the next decision checkpoint.

Freelancer, Employee or React Native Agency?

None of these models automatically supplies every capability. An agency proposal may cover engineering only; a freelancer may bring deep native expertise. Compare the people and responsibilities being offered, not just the engagement label.

Build a shortlist through relevant referrals, professional networks and specialist firms. Ask to meet the people who would do the work. Public repositories can help, but commercial developers may have little public code; a permitted walkthrough, reference or small paid exercise can provide alternative evidence.

Skills to Assess with Delivery Evidence

React, TypeScript and Maintainable Application Code

Ask the developer to walk through a feature they delivered. Look for clear handling of state, asynchronous requests, navigation, loading and error states. They should explain why they chose particular libraries and how another engineer would change the feature safely.

A long list of familiar packages is less useful than a concrete explanation of trade-offs. The appropriate state-management or data-fetching tool depends on the application; naming one library should not be the hiring test.

Native Integrations and Platform Differences

Ask which native SDKs they have integrated, what differed between iOS and Android, and what they did when a package was incompatible with the app. Look for evidence that they can investigate native build failures or work effectively with someone who can.

For an existing application, ask how they would check its React Native version, architecture and native dependencies before upgrading. React Native’s architecture documentation provides current context; interview questions about the legacy bridge alone are not enough to assess modern integration work.

Testing, Accessibility and Performance

Ask for the release checks that protect your main user journey, and why those checks are useful. React Native’s testing guidance explains a key limitation: JavaScript component tests do not exercise the underlying iOS and Android code. The proposed approach should also verify important behavior in the running app.

Discuss permission denial, interrupted sessions, failed requests and accessibility on both platforms. For performance, ask for an example of a measured problem: how it was reproduced, what profiling revealed, what changed and how the result was checked. Test against representative devices and data rather than relying on a smooth simulator demo.

Release and Maintenance Ownership

Ask who builds, signs, submits and supports each release. A strong candidate can explain how a change reaches users, how errors are detected and what happens when a release fails. Clarify responsibilities for dependency updates, OS compatibility, store requirements and security fixes.

Native iOS or Android experience is valuable alongside React Native expertise. For integration-heavy products, identify explicitly who can handle platform code instead of assuming one engineer must be equally strong in every area.

Interview Questions That Reveal How Someone Works

• Tell us about a feature you shipped on both iOS and Android. What differed, and what was your personal contribution?

• A required native SDK fails after an upgrade. How would you isolate the problem and decide between a fix, replacement or deferral?

• A user saves a change while offline. How would you define and test what happens when they reconnect?

• Users report a slow screen that looks fine on your development device. What evidence would you collect first?

• Which checks would block this feature from release, and which would you monitor after launch?

• How would another engineer build and release the app if you were unavailable next month?

Listen for specific examples, a sequence of investigation and a clear distinction between what they know and what they need to test. There can be several sound answers; evaluate the reasoning against your product’s constraints.

Use a Small, Relevant Assessment

Choose an assessment that reflects the engagement. For an individual engineer, a walkthrough of permitted code or a short paid exercise can reveal how they reason about a feature and its failure states. For an agency, a scoped discovery or integration investigation can demonstrate how the proposed team collaborates.

For example, ask someone to outline a record-editing workflow with a failed network request, explain the data handling and identify the tests they would add. If native integration is the main risk, test that integration instead of assigning a generic to-do app.

Agree the time limit, evaluation criteria and ownership of any output in advance. Avoid turning an assessment into an undefined production deliverable. Have the person explain their solution and make a small change so you can assess understanding as well as the result.

A Supplier Scorecard You Can Reuse

Mark each area as evidenced, partly evidenced or unverified, and record the example behind your judgment. Decide which requirements are essential before interviews; an attractive average score should not hide a missing critical capability.

Compare Costs on the Same Scope

An hourly rate alone does not show the cost of delivering your app. Ask for a breakdown that includes discovery, implementation, design where needed, integrations, testing, release work and coordination. Separate recurring tools or hosting costs from engineering effort.

For an existing application, a short assessment may be needed before committing to an estimate. Require assumptions about code quality, API readiness and dependency compatibility to be written down. Ask how changes to those assumptions will affect scope, timing and cost.

Compare proposals against the same first release and acceptance criteria. Check whether maintenance and handover are included. Our software project estimation guide provides a practical way to connect scope, effort and budget.

Confirm Ownership Before Work Starts

• Name the product decision-maker, technical lead and release owner.

• Agree access to company-controlled repositories, developer accounts, hosting and third-party services.

• Document code and asset ownership, permitted dependencies and handover responsibilities in the engagement terms.

• Keep build instructions, configuration guidance and release steps current as the app changes.

• Define support availability, incident handling, upgrade work and the process for ending or transferring the engagement.

Make handover demonstrable: someone outside the original implementation team should be able to follow the documentation, run the app and prepare a release. For an existing app with unclear dependencies or release risks, our mobile architecture assessment can help establish a prioritized starting point.

Choose a Team You Can Build With

Shortlist against your brief, verify the people and evidence, then agree a first delivery checkpoint. The right React Native partner should explain what can be shared across platforms, what requires separate work and who will own the product after launch.
