Your tasks include

  • Frontend & Backend: You develop frontend and backend components for web-based applications
  • Client work: You work directly with clients, analysing requirements and designing solutions
  • Databases: You design database structures and optimise queries for performance
  • APIs: You build RESTful APIs and integrate external services
  • Mentoring: You mentor team members, perform code reviews, and promote best practices
  • Risk management: You identify technical risks early and address them
  • Coding Assistants: You develop, test, and document with intensive use of LLM-based coding assistants

  • You have in-depth knowledge of modern UI frameworks, preferably Angular, alternatively React or Vue.
  • You have backend experience with Node.js and frameworks like NestJS
  • You have very good programming skills, embrace best practices, and have successfully brought software projects with TypeScript and Python into production.
  • You're getting the most out of LLM-based coding assistants: parallel sessions, MCP tools, Agent.md, workflow automation – and you're constantly looking for ways to be even more productive.
  • You have experience with databases, specifically MongoDB.
  • You have an eye for clean code and good user experience.
  • You have a hands-on mentality and get stuck in rather than discussing.
  • You enjoy encouraging others and sharing your knowledge.
  • You enjoy working in a team and can communicate effectively with people from different professions (technical and non-technical).
  • You have very good German language skills.
  • You have a strong sense of responsibility and recognise risks early on.
