Embedded Software Engineer

The current codebase is Rust-on-Embassy, but we’re language-agnostic on the role - strong C, C++, or Rust embedded engineers are equally welcome.

What you’ll do

• Own firmware end-to-end: drivers, state machine, communication protocols, command surface, bring-up, qualification, OTA / programming flow.
• Build the host-testable simulation surface. The state machine should be testable on a laptop without flashing a board - and stay that way.
• Work shoulder-to-shoulder with the HW engineer on bring-up, register-map ergonomics, and timing.
• Carry the firmware through environmental qualification (thermal, EMC, vibration).
• Define and enforce the firmware-side safety case.

Do you have experience in Universal asynchronous receiver-transmitter (UART) protocol?, * 5+ years of professional embedded firmware on ARM Cortex-M (or comparable) - in C, C++, or Rust.

• Deep comfort with interrupts, DMA, clocks, timers, low-power modes, linker scripts, memory maps.
• Strong with I²C, SPI, UART, USB CDC and debugging using scope / logic analyzer.
• Experience building state machines for real-world hardware.
• Discipline around testability and host testing.
• Working English, written and verbal.

Nice to have

• Rust embedded experience - Embassy, embedded-hal, defmt, probe-rs, RTIC, no_std ecosystem.
• Modern C++ embedded (C++17/20 in firmware).
• Async firmware experience (Embassy, Zephyr, FreeRTOS).
• Safety-critical firmware background: ISO 26262, DO-178C, IEC 61508, etc.
• Bootloader / DFU / secure-boot work.
• FPV / small-UAV firmware: Betaflight, MAVLink, INAV.
• C FFI / SDK bindings.

How we work

Small team, weekly hardware iterations, real boards on every desk. We expect concise, testable, safety-focused firmware development.
