Hire Senior Mobile App Developers in Europe
iOS, Android, and cross-platform engineers who ship to the App Store and Play Store on schedule - and design for offline, interruptions, and real-world mobile networks. Platform-native where it matters, pragmatic where it does not.
Engineers who actually fit the craft.
Every mobile app developers we place has been screened for the specific skills that matter in this discipline - not generic "software engineering" experience repackaged.
Platform-native depth
Real SwiftUI / Compose experience. Understands the idioms, the lifecycle, and the platform conventions your users already expect. Apps feel native, not like web views.
App Store fluent
Has shipped and maintained real apps through review cycles. Knows the rejection reasons, the privacy requirements, and how to keep release trains moving.
Cross-platform when it fits
React Native and Flutter engineers for the cases where shared codebase makes sense. Honest about when it does not.
Performance-conscious
Cold start, frame time, battery, memory - the mobile variables that web engineers forget exist. Our mobile engineers profile, not guess.
Engineers in our network. Real people. Long-term.
Every engineer Talzy places is a full-time, locally-employed team member - working exclusively for one company. Not a marketplace, not a rotation.
Every modern mobile stack, represented in the network.
Sourcing is stack-aware - the shortlist you see only includes engineers with production experience in the technology you specify.

Cross-platform
Backend-for-mobile
State & data
CI / CD & release
The moments a dedicated mobile actually earns their seat.
First dedicated mobile hire
You have a web product and are adding mobile. Maybe you are tempted by React Native for the shared codebase, maybe you need platform depth. A senior mobile engineer can walk you through the real tradeoffs - and then deliver whichever direction fits your product and team.
Rebuilding a neglected app
Your app has not had a proper release in a year. Swift migrations are overdue, the Android side uses AsyncTask, crash rate is awful. A senior mobile engineer can take ownership, bring it to current Swift / Kotlin idioms, and start shipping again.
Shared-codebase pragmatism
You are a small team and cannot afford two mobile engineers. A senior React Native or Flutter engineer with honest tradeoff judgement is the right hire - with the expectation that you will eventually split when the product scales or platform-specific needs emerge.
Performance / crash-rate rescue
Review ratings are dropping, crashes are up, cold start is slow. A Talzy mobile engineer with real profiling experience can surface the actual bottlenecks (battery, memory, jank) and ship targeted fixes - not a rewrite.
One brief, one shortlist, one mobile app developer on your team.
Tell us what you need. We come back in 3–5 business days with 3–5 mobile app developers who fit your stack, your seniority bar, and your team rhythm - already vetted, already interested.
Calculate your mobile cost.
Salary at-cost (no markup) + a tiered monthly management fee + a workspace fee. No recruitment fee. All shown in USD, per month and per year. Move the controls, see exactly what you will pay.
Typical monthly cost by seniority
All-in, including employment, workspace, and Talzy fee. Ranges cover our three active markets.
Owns features on a defined platform
Owns a platform end-to-end, ships to store alone
Drives mobile strategy, both platforms or KMM
The bar a mobile clears before you meet them.
Technical skill is table stakes - alignment, stability, and communication matter just as much. We screen for all four before anyone lands on your shortlist.
Shipped-app walkthrough
We look at a live app in the store that the engineer has actually shipped. Side projects are fine; production releases are the signal.
Platform fundamentals
iOS: memory model, concurrency, lifecycle. Android: coroutines, lifecycle, configuration changes. Cross-platform: native bridges and their limits.
Release process discussion
TestFlight / internal tracks, review rejection strategy, phased rollout. Engineers who have never shipped to store can't answer these without guessing.
Offline / networking design
How would you handle a feature that must work offline and sync later? Reveals real mobile engineering maturity.
Async communication check
Pull request review + written bug report. Clarity and specificity matter more than tools.
From brief to engineer-at-desk in 2–3 weeks.
Role definition
We lock in requirements, seniority, stack, team fit, and the non-obvious things (timezone overlap, oncall, tooling).
Curated shortlist
Sourced from our active talent network across Latvia, Lithuania, and Poland. Every candidate vetted by a Talzy engineer first.
Your interviews
You run the final technical rounds. We prep candidates on your stack and handle the scheduling friction.
Employ & onboard
Local contract, payroll, and equipment ready. Engineer joins your sprint cycle on day one.
Talzy vs the other options.
A side-by-side honest comparison against the common ways to hire a mobile app developer - marketplace contractors, in-house recruiting, and outsourcing agencies.
| Talzy | Toptal / Arc | In-house | Agency | |
|---|---|---|---|---|
| Time to first hire | 2–3 weeks | 3–6 weeks | 3–5 months | 4–8 weeks |
| Cost structure | Salary + flat fee | Hourly markup 50–100% | Fully loaded salary | 60–120% markup |
| Employment | Full-time employee | Contractor | Direct employee | Vendor staff |
| You own the relationship | Yes | Yes | Yes | No |
| Long-term retention support | Yes - career program | No | Your HR | No |
| Replacement if it fails | Included | Case by case | You re-recruit | Depends on contract |
We inherited a React Native app from an agency and were about to rewrite it native. Talzy sent us a senior RN engineer who showed us which 20% of the app needed native modules and which 80% was fine as-is. He kept us out of a six-month rewrite.
