Guide for founders and engineering leads
Hiring your first React Native engineer
A practical guide for founders hiring a first mobile engineer: product scope, architecture, native requirements, testing, and release ownership.
Hire for the whole delivery path
A first mobile engineer needs to connect product requirements to an application people can install and use. For a React Native product, that includes UI, API integration, native capabilities, testing, signing, store submission, and the process for diagnosing problems after release.
Before evaluating candidates, define who will own those decisions and what support is available from design, backend engineering, and product. A clear boundary makes it easier to choose the right seniority and assess whether the proposed delivery plan is realistic.
Write a useful project brief
A short brief should answer these questions before the team commits to a first release:
- Who is the first user, and which complete task must they be able to finish?
- Are the API contracts and authentication flows available, or does the mobile engineer also own that work?
- Which device capabilities are required: camera, notifications, payments, offline data, or background work?
- Which platforms, devices, and accessibility needs must the first release support?
- Who owns the Apple and Google developer accounts, signing credentials, release approval, and incident response?
What to expect from the initial engineering work
Start with a small working path through the real system: authenticate, load data, perform the primary action, and recover from a failure. That exposes integration and product risks early. Add architecture around known boundaries such as network access, persistence, navigation, and native modules.
Establish repeatable builds and a test strategy alongside the first feature. Critical flows deserve device-level checks; domain rules and API transformations need deterministic tests. Define which evidence is required before a change reaches users.
Questions that reveal delivery experience
Ask candidates to walk through a shipped product and the choices they personally owned.
- Which native integration was hardest, and how did you verify it on both platforms?
- How did you keep an API failure or an interrupted save from leaving the UI in the wrong state?
- What determined whether a change required a store build or could use an OTA update?
- How would another engineer reproduce the build and investigate a production error?
- Which decisions would you postpone until there is evidence that the product needs them?
Where I can contribute
My background combines hands-on React Native and Expo work with mobile architecture, C++ native modules, and engineering leadership. I work remotely from Brazil (UTC−3) with US and European time-zone overlap.
For a role discussion, share the product stage, team structure, and responsibilities. For a focused project, include the current stack, the problem you want to solve, and the delivery constraints. That makes the first conversation concrete.
