Senior Product Engineer - Android/Kotlin

Join us as an Android Engineer and help us build the mobile experience that 600,000+ European businesses rely on every day to manage their finances. You'll own product-critical features end-to-end — from technical design to rollout — in a large, modular Kotlin codebase where craft and velocity both matter.

What you'll do

• Own features end-to-end: You'll take ownership from discovery and technical design through implementation, rollout, and iteration on features that help businesses pay, get paid, and stay in control.
• Drive technical decisions in your squad: You'll shape solutions with Product, Design, and Backend by clarifying tradeoffs across UX, performance, security, and time-to-market.
• Raise app reliability and maintainability: You'll improve architecture, performance, and test strategy to scale the app without compromising stability.
• Tackle complex mobile challenges: You'll contribute to real-time synchronization, resilience patterns, and smooth navigation in a modular codebase with ~1,000 modules.
• Grow the team's Android craft: You'll lead code reviews and technical discussions, share patterns, and mentor peers to raise the bar on quality and delivery.

What you'll need

• Strong Android native experience: You've shipped and maintained production features with Kotlin and are comfortable owning technical decisions end-to-end.
• Quality-driven mindset: You care about testing (unit, UI, snapshot), clean code, and pragmatic standards that keep teams moving fast.
• Problem-solving approach: You thrive in ambiguity and turn complex constraints into simple, robust solutions.
• AI-native workflow: You use AI coding tools daily to amplify your output — not just experiment with them.
• Collaborative by nature: You're fluent in English and contribute through code reviews, knowledge sharing, and mentorship across technical and non-technical stakeholders.

What they offer

• An AI-first engineering environment: Unlimited access to Claude Code, Cursor, and Copilot.
• Engineering standards that scale: Strong code review culture, continuous refactoring, and a focus on correctness in a regulated context.
• A technically demanding domain: Fintech constraints — security, compliance, real-time data — push you to solve problems most mobile engineers never encounter.
