Embedded Software Engineer - Munition System

Job Description
Experience level: Mid-senior Experience required: 5 Years Education level: Bachelor's degree Job function: Engineering Industry: Defense & Space Compensation: $201,000 - $250,000 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 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. •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. Benefits How we work Small team, weekly hardware iterations, real boards on every desk. We expect concise, testable, safety-focused firmware development.
