DesignEngineer

ABOUT LUMBRA Lumbra builds the vendor-neutral operating system for agentic AI in high-consequence environments. In our first ten months we won four U.S. Government prime contracts in open competition, every one deploying into classified spaces, and we are live on JWICS. We were selected from a field of more than 200 companies and won, beat two established defense primes head to head, and earned the follow-on now in execution. Lumbra is a team of engineers and operators from the intelligence community, special operations, and frontier AI research, with degrees from MIT, Carnegie Mellon, West Point, and U.S. Army Ranger School and careers built at Palantir, Anduril, Northrop Grumman, Onebrief, JSOC, NSA, and CIA. They have lived this problem from the inside. ABOUT THE ROLE Nebula is one product serving two very different audiences. For the non-technical operators and analysts, the surface has to stay calm: the answer, the confidence behind it, and the sources, with nothing to fight through. The technical builders need the reverse: full transparency into the agents, tools, traces, and tradeoffs underneath. Within each audience, sub-personas work at a different altitude of detail and tolerate a different information density. We want a Design Engineer who lives between design and code, can hold all of them at once, and owns the design language that serves both without dumbing either one down. WHAT YOU’LL OWN - Create and steward the design system and brand architecture that spans both audiences, from the low-density operator surface to the high-transparency builder surface: tokens, themes, light and dark parity, and the component primitives that make opposite surfaces feel like one platform. - Prototype and ship novel AI interaction patterns: streaming output, tool-call visualization, citation surfacing, confidence indicators, and agent-to-human handoffs. - Translate product intent into production React and TypeScript, partnering with product, research, and backend engin
