TL;DR – We’re building humanity’s defense layer for the AI age and are looking for a Firmware Engineer to build systems that operate in real environments and survive contact with reality.
About the company
If you would have joined Nest before connected devices became commonplace—or Figure AI before humanoids left the lab—to build the firmware that made them trustworthy, 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.
