Security Engineer - Tech Lead

We are looking for a senior, hands-on security leader to build the security foundations that will support Luma’s next stage of growth. Our models and products are becoming critical infrastructure for creative professionals and enterprises. As adoption scales, we are investing in modern, principled systems for identity, access control, secrets, encryption, and safe operation of autonomous AI. This is a builder role. You will design and ship the platform security systems and operational tooling that allow us to move quickly while meeting the expectations of world-class customers—things like auth and identity infrastructure, fine-grained access scoping, break-glass escalation systems, and agent permission frameworks. You will partner deeply with infrastructure, research, and product teams to make secure design the default, not something bolted on after the fact.
