ROLE Firmus Technologies is seeking an Engineering Manager to lead the Platform Engineering and Observability team. You are accountable for both the people and the delivery: the engineers you grow and the platform software they ship. Your team builds and operates the platform beneath the Firmus AI Cloud, from bare-metal GPU compute and high-performance networking to the internal platform services, self-service tooling, and the observability platform that our engineering teams and customers depend on. You run these as products for the engineering teams that build on them, investing in self-service, reliability, and developer experience. You are the escalation point above first-line operations and own the cross-cutting decisions your team shares. This is a build-and-grow leadership role: you build the team that scales our AI platform toward gigawatt-scale AI factories across the regions and grow your scope as you earn it.
