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 - $250,000Total 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.
