Senior Engineer, Platform Infrastructure (R5516)

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems. We build and operate the platform that our engineers and our customers rely on. The platform isn't a product that's ever 'finished.' It's something we improve continuously. Every deployment, outage, bug, and annoying manual task is an opportunity to make the system better. An L3 Platform Engineer is a fully contributing member of that effort. This isn't a ticket factory. We expect engineers to think critically, collaborate closely, and continuously improve both the platform and the way we build it.
