Job summary

Allen Control Systems is seeking a firmware engineer to own low-level embedded software for autonomous fielded aircraft. You will decide between bare-metal and RTOS, integrate sensors, and design deployment strategies while shaping the HIL testing framework.

You’ll work on time- and safety-critical firmware with 4+ years of experience, using C/C++ and STM32 toolchains, contributing to robust, well-documented architecture choices and field-ready software.

Qualifications

• 4+ years of embedded firmware development; fluent in C and C++ required.
• Bare-metal and RTOS embedded architectures; strong working knowledge of CAN, I2C, UART and Ethernet.
• Bootloader design and firmware deployment for fielded systems; experience with hardware-in-the-loop testing.
• Strong ability to document and justify architectural decisions clearly and concisely.

Responsibilities

• Own the architecture and implementation of time- and safety-critical embedded firmware on STM32-based platforms; evaluate existing firmware ecosystems and decide what to carry forward or redesign.
• Write drivers for sensors and peripherals; configure CAN, I2C, UART, and Ethernet as needed for each use case.
• Define deployment strategies for fielded aircraft, including bootloader design and OTA/field update approaches.
• Set up and maintain hardware-in-the-loop testing infrastructure; document architectural decisions and tradeoffs clearly.
