Senior Developer (all genders)

Cologne / Technology

You are the one we miss!

  • You move confidently between software development and custom applications – this dynamic is exactly what makes agencies exciting for you
  • You keep track of everything, maintain existing web projects with care, and continuously evolve them
  • You have several years of experience with TypeScript/JavaScript and PHP – they're your daily companions. Debugging? For you, it's more puzzle-solving than a source of frustration
  • Agile DNA & communication skills: You think agile, speak plainly, and stay on top of current design and tech trends
  • You bring framework flexibility: React, Vue, or Angular? You know the playbook and understand exactly which tool is the best choice for which single page app
  • You consult with our clients openly, honestly, and with a focus on future-proof technologies that deliver real business impact
  • PURE CSS, DRY, KISS, and Clean Code aren't just buzzwords for you – they're the foundation for elegant digital solutions. Because we rely on proven technologies all the way to AI innovations
  • Nice-to-haves that make a difference: PWAs, SSR/SSG, State Management (React Query, SWR, Apollo Client), NodeJS, GraphQL, or CI/CD? Great, but not a dealbreaker
  • You have a German level of at least C2 (most projects are conducted in German), strong English is a plus

Not every buzzword on a list defines you? Perfect. Because we're looking for strong developers who are primarily excited about bringing digital projects to life that truly make an impact.
