Job description
As Senior JavaScript Developer, you will take the lead on our JavaScript applications, building the interfaces and services that power our products.
Your tasks will involve a combination of the following:
- Architecting and implementing robust frontend applications using React, TypeScript, and modern tooling.
- Building and maintaining component libraries with a focus on reusability, accessibility, and performance.
- Developing backend services using Node.js and TypeScript - APIs, server-side logic, and data layer.
- Building and maintaining CI/CD pipelines for our frontend and backend applications.
- Working on greenfield projects as well as evolving existing systems.
- Contributing to open source projects, or collaborating with the team building fun projects during our Open Fridays (usually on a Wednesday) :)
Requirements
Our primary requirement is a genuine passion for creating exceptional web applications, writing clean, efficient code, and an eagerness to collaborate on innovative projects.
Coupled with at least 4-5 years of hands-on JavaScript development experience, you're the kind of seasoned professional we're excited to invite for a coffee chat!
What we're looking for:
- Strong experience with React and modern frontend architecture
- Strong TypeScript skills across frontend and backend
- Strong experience with Node.js for backend services and APIs
- Experience with state management patterns and libraries
- Solid understanding of web performance optimization
- Familiarity with testing strategies (unit, integration, e2e)
- Experience with CI/CD pipelines and build tooling
- Familiarity with containerization (e.g., Docker)
We embrace AI tools to improve our workflows - and we're looking for someone who shares that mindset.
As a senior, you should be a great communicator who can explain complex technical ideas to different audiences. You're self-directed, collaborative, and able to navigate complex problems with pragmatic solutions.
Fluency in English is crucial for our international team. And if you can sprinkle in some German, that's a delightful bonus we appreciate.
Benefits & conditions
- 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
- Minimal meetings - we take planning seriously and spend our time coding, not in meetings
