Hire Mobile App Developers
Senior mobile generalists, or a compact team of them, for companies that have not yet chosen a stack or need several disciplines at once. They help decide between native and cross-platform, wire the app to your APIs, and stand up testing and release routines under your own leadership.

On your team
What a mobile app developer owns on your team.
02Owns
App-to-backend contract
Designs API shapes, authentication, pagination and error formats that suit flaky mobile networks.
03Owns
Cross-discipline delivery
Covers client code, a thin backend-for-frontend when needed, analytics events and crash reporting.
04Owns
Quality routines
Sets up automated tests, a device lab or cloud devices, and a checklist that each release passes.
05Owns
Release management
Runs store accounts, beta programmes, phased rollouts and version support policy for both platforms.
Hiring before the stack is chosen
Many companies start by hiring a Swift or Flutter specialist and only later ask whether that was the right platform. A generalist reverses the order: they study your audience, existing web skills and feature list, then recommend a stack. The paid exercise asks for exactly that recommendation, so you see their reasoning before they write a line of code.
Vetting
Skills we test before a mobile app developer joins.
01Tested
Breadth across stacks
Working knowledge of Swift, Kotlin and at least one cross-platform framework, with depth in one of them.
02Tested
API and auth design
OAuth with PKCE, refresh token storage in Keychain or Keystore, idempotent writes and offline queues.
03Tested
Push and messaging
APNs and Firebase Cloud Messaging setup, notification categories and deep linking from a tapped message.
04Tested
Observability
Crash and performance monitoring, structured logs and analytics that answer product questions.
05Tested
Store operations
App Store Connect and Play Console roles, review timelines, age ratings and privacy declarations.
06Tested
Estimating and scoping
Breaking a mobile roadmap into releasable slices and flagging features that are expensive on one platform.
Work sample
How the mobile app developer work sample runs.
- 01Step 1
Recommend a stack
Given a short product brief and team profile, the candidate writes a one-page recommendation on native or cross-platform with reasoning.
- 02Step 2
Connect a screen to an API
They build a sign-in plus data screen in their strongest stack, with token refresh and offline handling, completed in one paid day.
- 03Step 3
Draft a test plan
They outline which checks are automated, which are manual and which devices matter for your audience.
- 04Step 4
Map the release path
A discussion of beta groups, phased rollout, crash thresholds and how they would support older app versions.
Levels
Mobile App Developers: what changes at each level.
01Level 1
Senior
Builds features in the chosen stack, connects them to your backend and keeps the release checklist moving.
02Level 2
Lead
Runs a small mobile squad, owns the platform decision, architecture and store accounts, and reports to product.
03Level 3
Head of mobile
Shapes mobile strategy across products, hiring plans for specialists and the long-term balance of native and shared code.
Lead or head of mobile
A senior generalist suits a product with a known stack and a clear backlog. A lead fits when you need someone to own decisions and coordinate two or three engineers. A head of mobile is for companies with several apps or a plan to build an internal mobile function.
Other options
When to hire someone other than a mobile app developer.
01Consider
Stack already settled on Flutter
If the decision is made and the app is in Dart, a focused Flutter specialist is more efficient.
Open register02Consider
iPhone-only product
A single-platform app with deep Apple integrations needs a dedicated Swift engineer.
Open register03Consider
A mobile game
Games run on engines and frame budgets, so hire a game developer instead.
Open registerGeneralist or squad
An early product often needs one person who can build screens, adjust an API and submit to both stores. As usage grows, separate concerns appear: automated testing, release cadence and platform-specific features. We can add a QA engineer or native specialist alongside the original hire rather than replacing them.
Agree up front who owns the backend changes the app needs, because that boundary causes most delays.
Signs the hire is working
Four weeks in, expect a written stack decision, a skeleton app running on real devices through beta channels on both stores, crash reporting connected and an agreed API contract for the first feature. If any of those are missing, the gap tells you where to focus next.
FAQ
Questions to resolve before the build.
01We have no mobile app yet. Who should we hire first?
Usually a lead-level mobile generalist. Their first job is to recommend a stack based on your team and roadmap, then build the foundation that later specialists join.
02Can one person cover both iOS and Android?
With a cross-platform framework, often yes for an early product. Once native features or release volume grow, adding a platform specialist or a QA engineer keeps quality from slipping.
03How big can a hired mobile team get?
We typically start with one or two engineers and add a QA engineer, designer or platform specialist as the roadmap demands, all working inside your processes.
