Solid understanding of modern software engineering workflows, including CI/CD, testing, and observability. Excellent collaboration and communication skills across international and cross-functional teams. Proactive, responsible, and able to take end-to-end ownership of complex technical topics. Nice to have: experience in SaaS environments, Python or Go, and cloud-native deployment practices. Remote-first work with flexibility to attend occasional team events or workshops in European offices. Work-life balance initiatives, including E-Gym-Wellpass membership and job bike leasing.
