Your Impact
As a Senior Backend Engineer (m/f/d) at 7Mind, you’ll be part of a cross-functional team building technology that supports mental wellbeing at scale. You work end-to-end on features, take ownership of backend services and help shape a system that is reliable, maintainable and a pleasure to work with.
In 2025, we fully rewrote and relaunched the 7Mind app and backend. Our new platform follows Domain-Driven Design principles and deliberately focuses on “delightfully boring” solutions: simple, robust and built to last.
7Mind is part of the 7NXT Health Group (BuddyFit, Gymondo), bringing together strong engineering culture and a clear purpose: empowering people to live healthier lives.
