AI-generated questions, company research, and talking points tailored to this role


Responsibilities

  • 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.
  • 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.
  • Working English, written and verbal.

Requirements

  • 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.

Additional Information

Candidate must be comfortable completing an initial 1-month onsite training period in Kearneysville, WV, after which they will relocate back to work from either San Francisco, Los Angeles, or Washington DC. About The Project Client is 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.
