Mid-Level JavaScript Developer - Web/Mobile (f/m/x)

We're a distributed team of software developers passionate about delivering high-quality applications with a strong focus on performance, scalability, and robust solutions that don't bother us during a nice board game session on a Saturday night.

We specialize in digital healthcare and retail media - building products and services in German healthcare that make a real difference.

We are looking for a Mid-Level JavaScript Developer to join our team.

You'll have the opportunity to grow your skills on web and mobile applications, working flexibly from home and focusing on code, not bureaucracy. We value pragmatic solutions over dogma.

Profil

Requirements

Our primary requirement is a genuine passion for creating exceptional applications, writing clean, efficient code, and an eagerness to learn and grow.

With 3-4 years of hands-on JavaScript development experience, you're ready to take on more responsibility and grow with our team!

What We're Looking For

• Solid experience with TypeScript and modern JavaScript
• Working knowledge of React (components, hooks, state management)
• Interest in or experience with React Native for mobile development
• Familiarity with testing practices
• Eagerness to learn and improve
  
  

Bonus

• Native iOS or Android development experience
• Experience with Node.js backend development
  
  

We embrace AI tools to improve our workflows - and we're looking for someone who shares that mindset.

As part of our team, we value the spirit of collaboration and believe that software development is a team endeavor. Your ability to ask good questions and find pragmatic solutions is key.

Fluency in English is crucial for our international team. And if you can sprinkle in some German, that's a delightful bonus we appreciate.

Wir bieten

• A competitive salary
• Flexible working hours and hybrid work (mainly from home, with one office day per week in Berlin or Cologne)
• Learning budget for conferences, courses, and books
• Choose the gear you like
• Relocation support if you're moving to Berlin or Cologne
• Mentorship and growth opportunities with senior developers
• Minimal meetings - we take planning seriously and spend our time coding, not in meetings
  
  

Web and mobile apps don't build themselves, so we make sure to keep the office stocked with coffee, fruits, Club Mate & snacks. We hold regular team events - dinners, game nights, chess evenings, and board games at the office, plus seasonal whole-company events like go-kart racing and escape rooms.

Important note

Please be advised that a valid work permit for Germany is required for non-EU citizens. Unfortunately, applications without a valid work permit and sufficient German language skills may not be considered.
