Embedded Software Engineer — Munition System

Job Details Skills: ARM Cortex-M (or comparable) — in C, C++, or Rust. Experience building state machines for real-world hardware. 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. 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 Qualifications 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. Preferred Qualifications 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. Training & Relocation 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. #J-18808-Ljbffr MetaOption, LLC
