Planner 5D is a global hub for home design, uniting over 100+ million users in 230 territories around our planet (yes, we have 2 users connecting from Antarctica each month!). Our platform simplifies the home renovation process from concept to execution, and this process has never been more straightforward with our cutting-edge software. You don't need to be a professional designer to enhance your home or workspace. We are dedicated to streamlining the design experience, making the customization of dream homes accessible to everyone.
Our cross-platform presence spans Web, iOS, Android, Windows, and MacOS, ensuring seamless synchronization for our users. Planner 5D is more than just software; it's a vibrant community of enthusiastic and product-oriented professionals. From diverse backgrounds, our team collaborates across time zones, fueled by a shared passion to revolutionize the home design market.
We are constantly looking for like-minded talent eager to take ownership and drive innovation within our expanding suite of tools. Join us in shaping the future of home design.
We are looking for a Lead Android Developer who will take personal responsibility for every new feature inside the P5D product. This is a role for someone who still enjoys writing code and wants to have real influence on the product. You will work on complex parts like graphic engine, multiplayer technology and Ai, including: Design Generator for image-to-image creation, Plan Upload to convert files into projects, AI Designer for styling and furniture layout, and Bernard AI - an LLM that answers questions, gives advice, and controls the AI Designer.
We care a lot about quality - clean code, strong engineering standards, and decisions that drive the market. We keep things simple - no extra layers of approval when good judgment is enough. Our engineering team has real power to suggest better tech solutions and influence product. That freedom comes with real responsibility because your decisions will have a tangible impact in a product used by 100M+ users. We love to learn: we dive into challenges and give 100%. Every tough task is just a way to find a better solution and get better at what we do.
You will be surrounded by strong engineers with high standards. It is a demanding environment, but also one where good work is respected and where you can work on really interesting technical challenges - including the Editor, 3D engine, geometry, and rendering.

Our journey: Founded in 2017 by Alexandre and Steve, Qonto has grown to 1,600+ Qontoers serving over 600,000+ customers across 8 European countries. We have been profitable since 2023, and we are just getting started. Our beliefs: We hire for skills and potential. With 80+ nationalities, 45% women, of which 56% of women in our leadership team, diversity isn't a program; It's who we are. We've built a discrimination-free hiring process because the best teams are built on merit. AI at Qonto: AI is deeply embedded in how we work (here) - Every Qontoer gets unlimited access to the best AI tools. We want people who experiment without waiting for permission, push AI beyond the obvious, know when to trust it, and when to question it. ------------------------------------------------------------------------------------------------------ Location: You can choose to work at Qonto as long as you're living in (or willing to relocate to) either Germany, France, Italy, Serbia, Portugal, or Spain. ➡️ Mission 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. You'll work closely with Product, Design, Backend, and Frontend. ➡️ 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 we're looking for 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 we can offer you An AI-first engineering environment: Unlimited access to Claude Code, Cursor, and Copilot — and a culture that expects you to use them to raise the bar, not just go faster (click here to read our vision statement on AI) 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. ➡️ Our methodology, the Qonto Way We value upfront technical design, team reviews, and smart slicing — quality drives the velocity our customers need. Our org assigns one team lead per project across stacks, giving your team a clear mission and full autonomy on how it operates. Our lean toolbox, Kaizen and PDCA, lets you monitor and drive continuous improvement collaboratively with your peers and manager. Want to go further? Click here ➡️ Our stack & practices Kotlin-first & modern concurrency: 100% Kotlin codebase with Coroutines + Flow throughout. Architecture: MVVM + Clean Architecture with modular design (~1000 modules). UI direction: New screens built with Jetpack Compose, with a large share of legacy views already migrated. CI/CD & quality: GitHub Actions, Bitrise, Firebase Test Lab, Sonar, Fastlane. Testing culture: 26k+ unit tests, 14k+ snapshot tests, 500+ UI tests. Curious about how we tackle tech debt? Check out our talk from the last Droidcon here featuring Florian. ➡️ Your future team As an Android Engineer, you will join one of Qonto's squad teams, each organised around a clear project mission, with one team lead and full ownership of a product scope. You'll be part of a 140+ mobile engineering community within a 500+ Product Engineering department, working in focused teams of 5 to 10 people alongside Product, Design, and peers from Frontend and Backend.
