Software Engineer, Full Stack

</strong>If you would have joined Palantir, Nest, or Tesla at the very early start to build an infrastructure from scratch ? not just clean datasets ? 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.
