Software Engineer, Product

About this role

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.

*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.

What makes this role special?

• One of the first 10 engineers shaping hardware systems pre-Series A.
• Own firmware that leaves the lab and operates in some of the world’s highest-stakes environments.
• Work directly with the hardware lead across EE, firmware, and embedded systems.
• Operate in environments where hardware decisions have immediate consequences.
• Partner with RF, ML, and product teams to deliver integrated systems.
• Define the trust boundary between hardware and software.

What we’re looking for...

• 4–8 years shipping reliable production systems.
• Polyglot engineer comfortable moving between TypeScript, Python, and systems languages like Rust or Go as the problem demands.
• Comfortable deploying and integrating with cloud systems like AWS or GCP in production environments.
• Obsess over software quality, reliability, and maintainability.
