Senior IT Tooling Engineers are the architects, implementers and champions of our cloud‑native, container‑oriented tooling ecosystem. They blend deep technical expertise with thought leadership, ensuring our tooling stack delivers secure, sovereign services and aligns with business objectives.
We are expanding a modern, cloud‑native IT tooling platform that empowers our teams to innovate faster and deliver secure, sovereign services. If you’re a seasoned, pragmatic engineer who loves to combine architecture, experimentation, and mentorship, but can also focus on operational platforms, we want you on our team.
