Hire Android developers by skill
To hire an Android developer, test Kotlin and Jetpack Compose on a real screen with coroutines, offline data and different screen sizes, then interview on that code. DeveloperHiring sources, tests and ranks candidates. You keep the hire and pay a flat subscription, not an agency fee.

What does a Android developer do?
Android apps run on thousands of device types and versions. Good Android engineers plan for that, along with background limits and battery use. We test for those habits.
Which Android skills do we test?
The skill matrix for a Android role starts with these six areas. You can change the weights in the role builder.
Kotlin
Null safety, data classes, sealed types and extension functions used well.
Jetpack Compose
State hoisting, recomposition and previews.
Coroutines and Flow
Structured concurrency and cancelling work on lifecycle changes.
Architecture
ViewModel, repository pattern and dependency injection.
Device variety
Screen sizes, permissions and older Android versions.
Testing
Unit tests for view models and a few UI tests.
Which screening questions work for Android roles?
Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the Android library.
- Q1 How do you stop a coroutine from leaking when the user leaves the screen?
- Q2 What changes when you move a screen from XML views to Compose?
- Q3 How do you test on many devices without owning them all?
What does the Android coding task look like?
Order tracking screen. Build a Compose screen that shows live order status from a Flow, survives rotation and works offline. Time limit 90 minutes.
- Expose order state from a ViewModel as a Flow
- Render loading, live and offline states in Compose
- Keep state across rotation
- Test the ViewModel with a fake repository
class OrderViewModel(repo: OrderRepo) : ViewModel() {
val state = repo.status(orderId)
.map { OrderUi.Live(it) }
.catch { emit(OrderUi.Offline) }
.stateIn(viewModelScope, SharingStarted.WhileSubscribed(5_000), OrderUi.Loading)

failed polls_until_delivered, shows_error_on_timeoutHow do you tell a junior from a senior Android developer?
The test and the AI interview look for different signals at each level. Use these to set the seniority in the role builder.
| Level | What you should see |
|---|---|
| Junior | Builds Compose screens and follows existing architecture. |
| Mid | Owns features with coroutines, offline states and tests. |
| Senior | Leads modularization, performance and release strategy. |
How much does a Android developer cost?
Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior Android developers. Treat them as a starting point and check current surveys for your market.
Android salaries track iOS closely. Engineers with Compose and modular app experience usually earn more.
| Region | Typical range |
|---|---|
| United States | about 100,000 to 170,000 USD |
| Western Europe | about 50,000 to 90,000 EUR |
| Latin America and Eastern Europe, remote | about 35,000 to 75,000 USD |
| India | about 12,000 to 40,000 USD |

How does the Android shortlist work?
Android developers often publish libraries and sample apps. Public code shows whether they write modern Kotlin. Every candidate then goes through the same screen, the Android task and an AI interview about their own solution. Integrity signals show paste events, similarity and AI code likelihood.
The top five land on your shortlist with a scorecard each. Your team meets them and makes the offer. You keep the hire and pay a flat subscription, from $99 per month billed yearly, not an agency fee.
