Android Developer -Kotlin

Hey there! Triodos is on the lookout for a talented Medior/Senior Android Developer to join their team for an initial year, with the exciting possibility of an extension.

Your main gig will be diving into the communication features of their app, making sure it stays super stable, secure, and performs like a dream. You'll be teaming up with a fantastic bunch of folks - other Android and iOS developers, back-end wizards, UX designers, a Change Analyst, the Product Manager, and other key stakeholders.

But that's not all! You'll also be:

• Actively jumping into story refinements, bringing your brilliant ideas to the table.
• Crafting all the necessary unit and UI tests to keep things tip-top.
• Tackling and solving any production incidents that pop up in the app.
• Collaborating with a broad network of stakeholders, ensuring your work perfectly aligns with theirs, all built on a foundation of mutual respect.

The Vibe:

You'll be joining the Omnichannel Value Stream, which is buzzing with activity! It's made up of two native app development teams (Android and iOS), a back-end team, and a team dedicated to the website and email. Each app team is a cozy unit of 2-3 Android devs, 2-3 iOS devs, a tester, a change analyst, and a product manager. You'll be working hand-in-hand on app features, syncing up closely with the iOS developers and other teams. Sharing knowledge is a huge part of their team culture, which is pretty awesome.

Right now, they're deep into some major projects aimed at making their mobile app even better. Their big dream? To create an app that not only lets customers breeze through their daily banking but also gives them cool insights into the impact of their spending. You’ll be collaborating closely within your own Empowered Product Team and also with other teams in their Value Stream and across different domains. These teams have the autonomy to achieve outcomes from understanding needs all the way to tracking the impact of their creations.

To deliver top-notch software at a rapid pace, they really value clean code, a solid architecture, and design that's built for testing. They're rocking MVVM, Kotlin, and Compose, and their CI/CD pipeline is powered by TeamCity. Testing is a breeze with Compose UI tests, Paparazzi, and Espresso. Plus, they use contract-based API generation for both iOS and Android.

Triodos is super keen to hear from women and individuals from all sorts of diverse backgrounds. They offer a space built on mutual respect, collaboration, and growth. With flexible work arrangements, regular feedback (on code and more!), and chances to work towards your goals, they're all about helping every co-worker, whether internal or external, reach their full potential.

The Nitty-Gritty:

• Duration: As soon as possible (Z.S.M.) until November 2, 2027, with an option to extend.
• Location: Driebergen-Rijsenburg.
• Please note: Freelance arrangements aren't possible for this role.
• The position will be closed early once they receive 20+ applications, so don't delay!
• Crucially, please include a personal note from each candidate explaining their interest in this specific role and how they connect with Triodos Bank's mission and values.
• Applications can be submitted until: October 12, 2026, at 10:00 AM.
