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 doOwn 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.RequirementsRequired: 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 haveRust 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.BenefitsHow we work Small team, weekly hardware iterations, real boards on every desk. We expect concise, testable, safety-focused firmware development.
