Senior Android Developer

We are looking for a Senior Android Developer to join our expanding Team. 

Maintaining our start-up spirit, we prioritize thorough research, swift implementation of solutions, and ensuring that every effort we make benefits our users, employees, partners, and, of course, our business.

What You’ll Do

• Design and build new features for our Android application, used daily by business owners across Europe.

• Architect and implement reliable, intuitive solutions for:

  • Multi-account cash flow management

  • Banking transactions and payments

  • Physical and virtual card issuance, activation, and control

  • AI-powered accounting automation

• Build polished, responsive UIs using Jetpack Compose.

• Take ownership of code quality, performance, and stability — automated testing and thorough code reviews are non-negotiable.

• Collaborate closely with Backend, QA, Design, and Product — you'll be shaping solutions end-to-end, not just implementing specs.

• Drive technical decisions within your domain, challenge assumptions when needed, and proactively identify opportunities to build better.

• Contribute to CI/CD pipelines, tooling, and mobile best practices across the team.

Who You Are

You're pragmatic and have a proven track record of shipping products that matter. You communicate clearly across disciplines and thrive in a cross-functional environment where everyone is solving the same customer problem together.

Your experience includes:

• Strong knowledge of Kotlin (Java knowledge is a plus) and 5+ years of commercial Android development.

• Deep understanding of OOP, SOLID, and Clean Architecture.

• Solid experience with presentation layer patterns — MVI, MVVM, and MVP — and the ability to choose the right one for the context.

• Hands-on experience with our core stack: Reactive programming & async: RxJava, Kotlin Coroutines / Flow

• Dependency injection: Dagger 2, Hilt, or Koin

• Networking: Retrofit

• Navigation: Cicerone, Jetpack Navigation Component

• Modern UI: Jetpack Compose

• Practical experience with Firebase (FCM, Analytics, Crashlytics).

• Experience with Feature-module architecture in production.

• Confidence with Git / GitLab, including setting up and maintaining GitLab CI/CD.

• A builder's mentality — you care about the product, the users, and the outcomes, not just the code.

• Clear, concise communication in English across technical and non-technical audiences.

Nice to Have

• Background in fintech or experience with financial products — you understand the stakes.

• Solid grasp of mobile security best practices (especially critical in our domain).

• Experience profiling and optimizing UI performance — reducing overdraw, improving recomposition efficiency in Jetpack Compose, and hitting smooth 60/120fps rendering.

• Hands-on work with performance tooling: Android Profiler, Perfetto, Baseline Profiles, or similar.

• Published apps on Google Play you're proud of.

• An active GitHub profile with code you're happy to share.

• Hands-on experience with AI agents and LLM tools (Claude, Cursor, Copilot, etc.) — setting up agent environments, writing prompts, skills, and behavioral rules.

• Experience with AI-powered IDE tools (Cursor, Windsurf, GitHub Copilot, Claude Code, etc.) — including agent mode, rules files configuration, and integrating AI into the daily development workflow.

• Understanding of model capabilities and limitations — knowing which model fits which task and how to manage the context window effectively.

• Ability to evaluate and verify AI-generated output — using automated tests, linters, and critical review to catch hallucinations and errors.

• Awareness of AI security risks — prompt injection, data leakage, and safe handling of untrusted inputs in agentic workflows.
