Firmware Engineer, Secure Systems

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…
3–6 years writing systems-level firmware for embedded targets with real depth, not glue code on top of HALs
Strong command of C with the ability to adopt new systems languages (Rust, Zig, C++) when appropriate.
Proven background in red teaming, offensive security research, or adversarial testing targeting embedded systems and physical hardware.
Reasons about trust boundaries, failure modes, and adversarial inputs before they become vulnerabilities.
Thrived in an early-stage startup.
Comfortable operating without perfect specs or complete information.
U.S. Person status required (may involve export-controlled data).

What you’ll do…
Own firmware across RTOS, embedded Linux, wireless radios, GPS, and custom embedded hardware.
Write and maintain system daemons and firmware modules with strict fault isolation
Own secure boot and verified firmware update pipelines end-to-end
Conduct adversarial review of firmware attack surfaces (e.g. USB, BLE, UART, OTA) and close what you find
Partner with RF and ML teams on high-throughput signal capture and real-time processing pipelines.
Build and maintain hardware validation tooling; reduce bring-up friction on every successive board spin.
