Описание

A Senior Mobile Engineer is sought to build and harden the Android SDKs and on-device services that power app delivery, discovery, and monetization at carrier and OEM scale. The role sits on a small, autonomous team that owns its products end to end — from design through release, monitoring, and on-call — and focuses on reducing installation failures and enabling dynamic app delivery. The position is based in Warsaw, Poland, and follows a hybrid model that considers only candidates local to the posting location.

Обязанности

Design, build, and maintain high-performance Android SDKs and on-device services, with iOS work as the cross-platform footprint grows
Focus on reliability, footprint, battery, and security across the SDK and on-device services
Drive down install and delivery failures by improving package-manager reliability, dynamic app delivery (ASR), and recovery paths across a fragmented device and OS landscape
Partner with OEM and carrier integration teams to ship features within tight platform, privacy, and resource constraints
Extend on-device surfaces that power alternative distribution and brand-on-device experiences
Own the full lifecycle of what you build: instrumentation, alerting, rollout strategy, A/B experimentation, and on-call
Raise the bar on code quality through reviews, automated testing, and tooling, and mentor other engineers on mobile best practices

Требования

8+ years building production mobile software
Deep expertise in Android with Kotlin and Java and a working command of native internals
iOS experience with Swift and Objective-C is a strong plus
Strong grasp of asynchronous programming, concurrency, memory and battery profiling, data structures, and mobile design patterns
Experience shipping SDKs, libraries, or framework-level code consumed by other developers, not just app features
Track record of operating what you build in production at scale, including monitoring, debugging field issues, and staged rollouts
Comfort working in a fast-paced, autonomous, outcome-oriented team
Nice to have: experience with AdTech, mobile measurement or attribution, or on-device ML inference
Nice to have: familiarity with OEM and carrier pre-load constraints, Android system apps, or device-management contexts
Nice to have: exposure to alternative app stores or in-app purchase and payments flows
