Job Description

For our team in Berlin we are looking for a Senior Backend Engineer Node.js / TypeScript (d/f/m) within our newly formed Transactional Business Unit! Our mission is to enable our customers to do the mobility changes that they need (buying and selling of vehicles, including concerns on the way like financing and insuring a car) completely online, and to enable the more that 40.000 car dealers in Germany who are our partners to compete in this increasingly digitised market by providing them top-in-class tools and processes. This specific role is in the Online Buying team which builds products that integrate our transactional products in the mobile.de Core experience.

Your role:

  • Build the next generation of car online buying. You'll build the infrastructure for mobile.de from the ground up, having a huge and direct impact by shipping your work to users on prod daily

  • Create a robust and scalable backend. Build performant REST API with Redis cache, MongoDB, 3rd party integrations, product analytics, and service monitoring

  • Use modern web tech and influence the stack. The backend is Node/Express, the frontend is React, and we use TypeScript across the full stack. As we build out our stack, you get to make critical choices and lay the foundations. While frontend doesn't have to be your forte, you may implement basic UI components based on Figma mocks and our design system

  • Self-direct your work and co-own the product. You're a technical founder type and will have autonomy and responsibility. You'll be involved in shaping the roadmap and will own mobile.de's exploding backend needs

  • Solve interesting technical problems. Bring your full creativity to solve super-challenging technical problems: from complex backend architecture with 3rd party integrations, syncing app state, to real-time collaboration


  • Highly productive while producing quality code. You enjoy pushing out features in a pragmatic and maintainable way. You know when to use duct tape and when to lay a foundation

  • Curious and quick learning. We don't expect you to have experience in every technology we use, but to learn and be productive quickly. Owning several repos and jumping into all of them doesn't scare you

  • Design sensibility. While you'll co-craft the interface with top designers and frontend engineers, we expect you to have a knack for great UX, such that you feel if something is off and can flag it, or better yet, polish it

  • Attention to detail while pragmatic. We strive for few slips in code, Git hygiene, and clear written communication — all while remaining low-ego and simply focusing on solutions

Additional Information

  • Opportunity to shape the way we work. Your feedback and opinions are valued at all levels of the organisation
  • Benefits including stock purchase plan and annual bonus plans
  • Flexibility to work when and how you want - flexible hours, autonomy to set your own agenda, choice of phone and computer
  • Smart Working Policy - work remotely some of the time, balanced with time in the office together with your team - between 5 and 45 days per quarter in the office depending on each team. (Please clarify this for your team during your first interviews!). 
  • ‘Work from anywhere’ weeks - up to four weeks working from anywhere, including from another country, as long as you have an internet connection!
  • Career development, including individual training budget and language classes
  • 28 days of holidays
