The practical way to hire Android developers
When you hire Android developers through us, you skip sourcing and go straight to interviewing people who have already been vetted for senior Kotlin work. A brief on day one, a shortlist within days, your interviews, then contracting and access, which normally puts someone in your repository in 10 days or less. They take direction from your Android lead and follow your review and release rules. We stay responsible for employment, payroll and contracts, sign an individual NDA per engineer, and assign IP to you. We were founded in Yerevan in 2019 and have offices in Newark, Yerevan and Hong Kong.

Where Android app developers add the most
Compose migrations and new UI
Moving screens from XML views to Jetpack Compose without freezing the roadmap, and building new surfaces in Compose with state handling your team can follow later.
Stability across devices
Crash and ANR rates, background execution limits, battery behaviour and the long tail of API levels and screen sizes that only show up in production analytics.
Play Store and delivery
Gradle build health, signing, staged rollouts, Play Console policy requirements, and CI that produces a release candidate without a manual checklist.
From brief to embedded in 10 days or less
Brief
A 30-minute call covering the app, how much of it is Compose today, the seniority you want, and the hours your mobile team keeps.
Shortlist
Profiles of the Kotlin engineers who would actually join, with the apps they shipped and the parts of delivery they have owned.
Interviews
Your interview loop, run your way. We coordinate scheduling and answer questions, and nobody is placed without your approval.
Embedded
Contract, NDA and access, then they pick up scoped tickets inside your sprint, your review rules and your release train.
Comparing your options for Kotlin developers for hire
Look past the headline and compare the parts you will feel in month two: who filtered the candidates, who the engineer answers to, and how a bad fit gets resolved.
| Option | Hire through Yoocollab | Freelance marketplace | Direct hire |
|---|---|---|---|
| Time to start | 10 days or less, including your interviews | Fast to contract, slow to filter | Months of sourcing plus notice periods |
| Vetting | Pre-vetted senior Kotlin engineers, then your own loop | Profiles and reviews you verify yourself | Your full recruiting process |
| Who manages | Your Android lead, in your reporting line | You, around their other clients | You |
| Replacement | We source a replacement and handle the handover | Back to searching | A fresh hiring cycle |
| Commitment | Per engineer, flexible as the roadmap changes | Per contract, often short | Permanent headcount |
Common questions
How quickly can I hire Android developers?
The usual path is 10 days or less between the first brief and an engineer committing code in your repository. We shortlist within a few days, you run interviews, then contracting and access follow. Narrow requirements such as an unusual SDK or hardware integration can add time, and we flag that at the start.
Do your Android engineers work in Kotlin or Java?
Kotlin is the default and Jetpack Compose is where most new UI work happens. Plenty of production apps still contain Java and XML layouts, and our engineers are comfortable working in mixed codebases rather than insisting on a rewrite before they contribute.
Can they handle device fragmentation and Play Store releases?
Yes. That includes testing across API levels and screen sizes, tracking crash and ANR rates, staged rollouts, and Play Console policy work. Release engineering is treated as part of the job, not a separate handover.
How do they fit into an existing mobile team?
They join your standups, your board and your review rotation, and they report to your Android or mobile lead. We keep employment, payroll, contracts and a regular check-in on our side so the engineering relationship stays between you and the engineer.
What if an engineer is not the right fit?
Tell us early. Because you interview and approve every engineer before they start, most fit problems are caught before anyone joins. If one still appears we replace the person rather than debate it, and we handle the handover so context is not lost.
