Product Security Engineer

Base's batteries are internet-connected industrial control systems in miniature. Installed across thousands of homes, together they operate as a distributed power plant. The attack surface runs from silicon to cloud.

You'll own the end-to-end security of the fleet and how it interacts with the world. The fleet is live today and scaling quickly, so the exposure is real and compounds with every install. This is a generalist role: you'll go wherever the risk is highest, across software, firmware, hardware, and cloud. You'll dive into unfamiliar systems, bottom out assumptions, and prove what's actually true.

Base's Product Security team owns the security of a fleet that's already live in thousands of homes and scaling fast, from the SoCs and boot chains inside each battery to the cloud services commanding them. The team is small and generalist by design. Rather than splitting into narrow specialties, its engineers go wherever the risk is highest, moving fluidly across firmware, hardware, software, and cloud. The team's job is equal parts establishing what's actually true about the fleet's current state and building the lasting foundations, like device identity, signing, and certificate lifecycle, that let it keep scaling safely.
