Embedded Hardware Engineer

TL;DR - We're building humanity's defense layer for the AI age and are looking for an Embedded Hardware Engineer to build systems that operate in real environments and survive contact with reality.If you want to build systems that leave the lab and operate under real conditions — this is that role.Why Sweep?As intelligent machines proliferate into every part of the physical world, we humans still lack a defense layer to ensure the systems and devices we rely on remain aligned with us.We're building that layer today by deploying alongside the world's highest-stakes teams — Olympic delegations, F1 paddocks, halftime shows, global tours, studio productions, senior government officials, and executive protection units. What we learn there becomes the foundation for a civilization-defining capability.We're a small, talent-dense team with high ownership, high velocity, and low ego. We care deeply, move fast, and are here to build something that outlasts us.Together, we'll redefine cyber-physical security for the AI age.What makes this role special?One of the first 10 engineers shaping hardware systems pre-Series A. Own hardware that leaves the lab and operates in real environments. Work directly with the hardware lead across EE, firmware, and embedded systems. Operate in environments where hardware decisions have immediate consequences.
