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., * 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 ## Related Videos - [Code to Road in < 12 hours](https://www.wearedevelopers.com/videos/1082-code-to-road-in-12-hours) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) ## Related Articles - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers)
