About the role

Key responsibilities & impact

As a Software Developer on Android, you’ll own the systems, architecture, and tooling behind apps used by millions — operating strategically across mobile, backend, and data, and diving into the lowest-level details when the problem demands it.
Design, develop, and sustain high-performance Android applications in Kotlin and Jetpack Compose, with legacy Java interop, and AI tooling embedded throughout your workflow.
Own the full lifecycle of your systems: feature ideation, API design, instrumentation, CI/CD deployment, live-traffic monitoring, unit/UI/e2e testing, telemetry and data analysis, A/B experiment design, and continuous iteration.
Lead architectural modernization — decompose monoliths, build shared libraries and frameworks, improve modularization, and enable reuse across Android, iOS, and Web.
Evaluate and adopt new Android platform capabilities (OS releases, device types, form factors, architectures) and lead their rollout.
Build and extend our internal AI harness — agents, automation frameworks, evaluation pipelines, and guardrails — so the whole team ships faster and safer; continuously evolve how you use AI and push the org’s standards for what “good” looks like.
Define observability standards, telemetry pipelines, and fault-tolerance strategies for production-grade mobile systems.
Partner closely with product, design, backend, and data; drive technical discussions, mentor developers, and influence strategic direction across mobile.

Requirements

What you’ll need

Deep experience building production Android applications with Kotlin and Jetpack Compose. We care less about tenure and more about the complexity of the problems you’ve solved, the systems you’ve shipped, and the engineering decisions you’ve led.
You’ve personally owned and operated a consumer Android app at significant scale — 1M+ monthly active users or comparable — across many release cycles. Contributing to such an app is not the same as owning it.
Daily, fluent use of AI coding tools in real production work today, with the comfort to let AI generate the majority of your code while you own correctness, architecture, and quality.
Deep command of Kotlin Coroutines and Flow, and Java interop within a large, long-lived codebase.
Technical leadership across multiple teams: you’ve owned the architecture of a major system or module, set technical direction, and mentored senior engineers.
Hands-on ownership of production reliability for mobile clients: SLOs/SLIs, instrumentation and telemetry pipelines, on-call rotation, and incident triage.
A track record of measurable wins — performance, reliability, or user impact — that you drove, not just participated in.
