Senior Software Engineer, Embedded Systems

Senior Software Engineer, Embedded SystemsByron, CAEngineering /Full-time /Hybridapply for this jobAt Elroy Air, we build autonomous vertical takeoff and landing (VTOL) cargo drones to change the way the world moves goods. Transporting cargo by air is faster and more direct than by land or sea, but it has been prohibitively expensive for medium-size loads. We've set out to expand middle-mile logistics possibilities across multiple sectors, with our sights on a $420Bn global total addressable market for cargo logistics across defense, commercial and rapid response. We are a team of builders, engineers, and operators who believe that the defense, commercial, and rapid response communities need faster, better logistics solutions. We are seeing increasing demand as customers and prospects respond enthusiastically to the systems we’ve built. As we mature and deploy our offerings, we are looking for people like you: motivated collaborators, enthusiastic about our mission and ready to roll up their sleeves and make a big impact to improve how logistics works around the world. You will play an important role in establishing the Elroy Air Chaparral as the industry standard in this massive market. We believe diverse perspectives at all levels of the organization are critical to innovation and employee development. This includes but is not limited to gender identity, race, ethnicity, sexual orientation, gender expression, religion, age, ability, parenthood status, veteran status, educational background, citizenship status, or any combination of these characteristics.Elroy builds autonomous aerospace systems for the real world. At the heart of those systems is a hard real time, safety critical software stack that has to work under any circumstances, with no margin for "close enough". The embedded software team writes the code that flies the plane in any conditions. This role spans the full embedded stack, from bare-metal firmware and RTOS integration to hardware bring-up and bench debugging. If you thrive on hard constraints, enjoy working close to the metal, and want your code to matter, read on.The RoleAs 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...
