• Collaborate closely with product, customers, and other engineers; scope your work, keep people in the loop, and drive things to completion

• Experience in full-stack development with .NET C# or strong OOP language background
• Frontend: React and/or Angular + TypeScript
• Fully embrace AI; use AI in the SDLC and understand its pros and cons
• Can pick up work in both new and legacy code
• Move fast while still caring about code quality, security and safe shipping
• Want to stay and grow with a team and a product over the long term
• Nice to have: built and deployed own agents or dev-tooling

• Nice to have: worked directly with end-users / customers

• Good salary based upon knowledge and experience
• Resources: all tools needed, including a MacBook from day one
• Hybrid set-up with offices in Netherlands, Gdansk, and Germany
• Work from home possibility
