Senior JavaScript Developer (f/m/x)

Hi! We are verkstedt .

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 seasoned Senior JavaScript Developer to join our team.

You'll have the opportunity to shape and evolve large-scale web applications, focusing on code, not bureaucracy. We value pragmatic solutions over dogma.

Tasks

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

• 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

Web applications 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.

If this sounds like you, get in touch! Simply fill in the application form below and we’ll get back to you within a week.

We’ll start with a quick chat via Zoom (or whatever works) to get to know each other and answer any questions you might have.

If we’re all keen to continue, we’ll invite you for a coding demo - a chance for a deeper discussion about your work.

And that’s basically all the application process there is.
