Senior Android Engineer

Company:

SimpleStudy is a consumer AI platform for students.

We help them stay motivated to study their subjects - everything from Biology and Mathematics to Literature and Art.

Our small team has already helped +1.5 M students worldwide (UK, Ireland, Brazil, South Africa, and Australia) study better, and ~40–50k new students join us every week.

We are a remote team with a Lisbon office, having recently raised ~$4M seed round with incredible investors from Strava, OpenAI, and Meta.

Responsibilities and key results:

Own the mobile app end-to-end — architecture, performance, release process, and roadmap — without needing the problem framed in advance

Lead and mentor the two existing engineers already supporting mobile, setting technical direction and raising the bar for mobile craft

Partner directly with Affan on engineering strategy and with Oisin on product direction where mobile intersects with growth, onboarding, and retention

Drive native-feel polish: smooth animations, responsive interactions, platform-specific conventions (iOS/Android)

Work in a PLG/A/B testing environment — ship features, instrument, measure impact, iterate fast

Own app store presence and release cadence — versioning, store optimization, crash/performance monitoring

Potentially help grow a dedicated mobile team as the app becomes a bigger part of the business
