Services for Renewable Energy Munich, Bavaria 11–50 employees Public Company

Golfstrom operates a financing platform that lets regional solar companies offer customers installment options for residential installations. The stack (Vue + Rails + GraphQL) supports a straightforward web application; hiring velocity is accelerating with 3 roles posted last month, but the team remains intern-heavy (4 of 6 active headcount), suggesting early-stage execution on core platform maintenance and testing rather than scaled operations.
