DevSecOps Engineer with Kubernetes (f/m/x)

Join our engineering team to develop an APM operator for a Red Hat MicroShift–based platform. The operator will enable containerized applications to use mutual TLS (mTLS) for internet‑facing connectivity. You will work closely with the operating system and Kubernetes stack, designing an operator and an access layer for hardware security (TPM) to securely manage private keys.

By joining us, you become a member of the Embedded Competence Center at Sii is an internal organizational unit bringing together more than 500 specialists nationwide! We are currently working on about 100 projects for 50 clients from various industries, including automotive, IoT, telecommunications, and medical.
