About the project We're building a small, safety-critical kinetic munition delivered by an FPV-class airframe. The compute side is an electro mechanical safe and arm device (EMSAD). 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.

Requirements

• Required
• 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.
• 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.

Benefits

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