To hire a mobile engineer at a startup, decide first whether you are building native iOS, native Android or cross-platform, because that choice defines the person you need. Then hire for release discipline as much as coding skill, since a bug in an app stays on users' phones long after you fix it. A tight scorecard and a paired exercise on a real screen from your product will tell you more than any quiz.
Many founders open a "mobile engineer" role before deciding how the app will be built, and ask the first hire to make that call. It sounds sensible, but it means the job description attracts everyone, the interviews test different things for different candidates, and the platform decision gets made by whoever you happen to hire. Your first mobile engineer tends to set the architecture you will live with for years, so it pays to decide it deliberately.
Make the platform call before you write the job description
Two questions settle most cases. Does your core product depend on deep device features, such as Bluetooth, camera processing, background location, offline sync or heavy animation? And do most of your users sit on one platform?

Here is an illustrative example. A field-service startup builds an app that technicians use on company-issued Android phones, often with no signal inside buildings. Offline sync is the core of the product, and almost every user is on one platform. That team should hire a native Android engineer with offline experience, and leave iOS until a customer needs it.
A consumer marketplace built mostly around lists, profiles, payments and messaging looks different. Its users are split across both platforms and the device features are standard. A cross-platform engineer who has shipped to both app stores will usually get it further, faster, with one codebase.
Why release discipline matters more on mobile
On the web, a fix reaches every user the moment you deploy it. On mobile, the fix has to be built, tested, reviewed by the app store and then installed by each user, and some of them will run the old version for a long time.

That changes what good looks like. Strong mobile engineers design for it: feature flags, staged rollouts, crash reporting, backwards-compatible APIs and a habit of testing on real devices. Ask every candidate how they handled a bad release. The quality of that answer is one of the best signals you will get.
A scorecard for your first mobile hire
Keep the scorecard to four or five areas and score each on a simple 1 to 4 scale after every interview. The weightings below suit a first or second mobile hire, so adjust them if you already have a mobile team.
| Area | What strong looks like | How to test it |
|---|---|---|
| Platform depth | Has shipped and maintained a live app on your chosen platform, and knows its lifecycle and quirks | Walk through an app they shipped, screen by screen |
| Release discipline | Uses flags, staged rollouts and crash reporting without being asked | "Tell me about a release that went wrong" |
| Product sense | Pushes back on designs that feel wrong on a phone and suggests simpler flows | Review one of your own screens together |
| API collaboration | Thinks about versioning, offline states and slow networks when agreeing APIs | Design the data contract for one feature with a backend engineer |
| Ownership | Comfortable being the only mobile engineer and making calls alone | References from a previous small team |
For the practical stage, pair on a real screen from your product for an hour or so. You learn how they handle state, layout and edge cases, and they see the codebase they would inherit.
Where to find mobile engineers
Mobile engineers who have shipped their own side projects are worth seeking out, because they have handled the whole release cycle alone. Look at app store listings as well as profiles, and ask candidates to show you the apps on their own phone. Engineers from larger companies can be excellent too, but check that they have owned releases end to end rather than a slice of a big app.
What a recruiter costs for a mobile hire
At an illustrative base salary of $140,000 (swap in your own), a contingency recruiter charging 20 to 25% would bill $28,000 to $35,000. On Funded.club's fixed-fee bands the same hire costs $11,500, agreed before the search begins. See pricing for every band.

Frequently asked questions
Should a startup hire a native or cross-platform mobile engineer?
Hire native if your product relies on deep device features or most users are on one platform. Hire cross-platform if you need both app stores, the features are standard and you want one codebase for a small team.
Can a web engineer build our mobile app?
For a simple first version on a cross-platform framework, sometimes. For anything that depends on device features or needs polish, hire someone who has shipped and maintained a live app, because the release cycle and platform rules take time to learn.
What should I ask a mobile engineer in an interview?
Ask them to walk through an app they shipped and a release that went wrong. Their answers show platform depth, how they handle risk and whether they own releases end to end.
How much does it cost to hire a mobile engineer through a recruiter?
Contingency recruiters usually charge 20 to 25% of first-year salary. Funded.club charges a fixed fee by salary band, for example $11,500 for a role paying up to $150,000.
