# Embedded Software Engineer

- **Company:** The Hire
- **Location:** Washington, DC, United States
- **Salary:** $250,000.0
- **Contract:** Permanent contract
- **Skills:** ARM Architecture, Booting (BIOS), C++ (Programming Language), Communications Protocols, Software Debugging, Embedded Software, Firmware, FreeRTOS, GNU Linker, Universal Asynchronous Receiver/Transmitter, State Machines, DO-178B
- **Published:** May 31, 2026
- **Apply:** https://www.indeed.com/viewjob?jk=61bd8259b0829114

## About the Role

Do you have experience in Universal asynchronous receiver-transmitter (UART) protocol?, * 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.

How we work

Small team, weekly hardware iterations, real boards on every desk. We expect concise, testable, safety-focused firmware development.

Required

5+ years of professional embedded firmware on ARM Cortex-M (or comparable) - in C, C++, or Rust.

C FFI / SDK bindings., * ARM Cortex-M (or comparable) - in C, C++, or Rust: 5 years (Required)

 * low-power modes, linker scripts, memory maps.: 1 year (Required)

## Description

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.
