About
The Role As a Senior Embedded Software Engineer, you will own software that runs directly on safety‑critical avionics hardware including our main flight computers. You will work at the intersection of firmware, real‑time systems, and hardware bring‑up, and you will contribute to a team culture where everyone is expected to understand the system end to end. This is not a siloed firmware role: you will interact with engineers from a wide variety of disciplines on a daily basis, including systems engineering, controls, flight physics, power electronics, and aeromechanical.
What You'll Work On
Embedded firmware for microcontrollers and SoCs in a bare‑metal and/or RTOS environment (FreeRTOS, Zephyr, or similar)
Driver development, peripheral integration, and board bring‑up for custom hardware platforms
Real‑time control loops and sensor fusion pipelines where timing and determinism are non‑negotiable
Hardware debugging: oscilloscopes, logic analyzers, JTAG, and willingness to get comfortable with a schematic
C++ and Python tooling for testing, scripting, and automation around embedded targets
Development of models and emulators for aircraft components to ensure hardware behavior is faithfully represented in our cloud simulation framework
What We're Looking For You probably have:
5+ years of professional embedded software development, with production firmware shipped on real hardware
Deep fluency in C and/or C++; Python for scripting and test tooling
Hands‑on experience with at least one RTOS and with bare‑metal development
Comfort reading schematics, using bench instruments, and debugging hardware/software integration issues at the signal level
Experience with communications protocols: SPI, I2C, UART, CAN, Ethernet
Strong opinions about code quality, testability, and the difference between software that works in the lab and software that works in the field
It's a bonus if you have:
Experience in aerospace, defense, robotics, or other safety‑critical domains
Familiarity with DO-178, MISRA, or other embedded software standards
Exposure to desktop tooling or visualization for hardware debug and test workflows
Experience with CI/CD pipelines for embedded targets (HIL, SIL, emulation)
Our Stack
Primary languages: C++ and Python
RTOS: FreeRTOS and bare‑metal depending on target
Toolchains: GCC/Clang cross‑compilers, CMake, custom build infrastructure
Version control and CI: Git, GitHub, cloud‑based batch simulation and test runners
Modern AI coding tools used as productivity accelerators, not as a substitute for engineering judgment
Who We Are Elroy's software team is small, senior, and exceptionally cross‑functional. Most engineers here are comfortable working across embedded firmware, desktop tools, and cloud infrastructure. Not because we expect everyone to be an expert in everything, but because we value curiosity and adaptability over and above having all of the answers on day one. We're looking for someone who brings deep experience in embedded and real‑time systems, and isn't afraid to range beyond that when the work calls for it.
