Embedded Software Engineer — Munition System

Experience level: Mid-senior Experience required: 5 Years Education level: Bachelors degree Job function: Engineering Industry: Defense & Space Compensation: $201000 - $250000 Total position: 1 Relocation assistance: No Recruiter Note: 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 Were 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 were language-agnostic on the role strong C C or Rust embedded engineers are equally welcome. What youll 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. Working English written and verbal. Nice to have Rust embedded experience Embassy embedded-hal defmt probe-rs RTIC nostd ecosystem. Modern C embedded (C17/20 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. Benefits How we work Small team weekly hardware iterations real boards on every desk. We expect concise testable safety-focused firmware development.
