AI tools are mandatory, not a bonus Claude Code, Copilot, Cursor: You must be able to work productively with these. Not because we want to be trendy, but because our customers expect it and we work that way too. If you think AI tools are a hype and prefer to type everything yourself: wrong company. Internally, we invest in your AI skills. What we offer Home office, office or mix – you decide MacBook (unless the customer provides their own hardware) Different customers, different projects The founders are your direct contacts Internal upskilling in AI development Application Resume is sufficient. No cover letter needed. After a short video Q&A round (2×90 seconds) we'll get back to you within a few days. [Auto-translated from German]
