Position Description:Â Protingent Staffing has an exciting direct hire Senior Embedded Firmware Engineer (Avionics / Platform Interface) opportunity.
Job Responsibilities:
- Design and implement bootloaders, BSPs, HALs, and low-level device drivers tightly coupled to custom avionics hardware.
- Bring up new ARM-based flight boards from first power-on through stable firmware operation, working directly from schematics and hardware documentation
- Build firmware using bare-metal and/or RTOS architectures with deterministic timing and fault tolerance.
- Develop low-level flight firmware as part of system fault tolerance to, including command and telemetry handling, health monitoring, FDIR, safe-mode behavior, and autonomous recovery.
- Customize and integrate Jetson Linux platforms, including boot chain, device tree, kernel bring-up, and MCU to Jetson interfaces.
- Debug and resolve hardware–software integration issues, collaborating closely with avionics and systems engineers through test and flight readiness.
- Implement and validate power sequencing, reset handling, watchdogs, interrupt
- handling, DMA, and linker configurations.
- Customize and integrate Jetson Linux platforms, including boot chain configuration, device tree updates, kernel bring-up, and MCU-to-Jetson interfaces.
- Debug and resolve hardware–software integration issues using JTAG/SWD, oscilloscopes, logic analyzers, and other bench tools.
- Collaborate closely with avionics hardware, systems, and mission teams through integration testing, protoflight activities, and flight readiness reviews.
- Develop and maintain MCU-side firmware supporting power, thermal, communications, and telemetry functions.
- Support and evolve redundant communication paths (e.g., dual CAN) for coordination, monitoring, and fault tolerance. Define, document, and maintain stable firmware interfaces consumed by higher-level platform software.
- Partner with software engineers to ensure firmware behavior aligns with system-level requirements and operational constraints.
- Contribute to embedded build automation, reproducibility, and test infrastructure where appropriate.
Job Qualifications:
- 7+ years of hands-on embedded firmware development experience in the aerospace, robotics, automotive, or other safety- or mission-critical systems environments.
- Expert-level proficiency in C/C++ for embedded systems.
- Strong experience with ARM Cortex-M (M4/M5/M7 or similar) architectures.
- Proven experience developing bootloaders, BSPs, HALs, and hardware-facing device drivers.
- Demonstrated ability to bring up new hardware from schematics to working firmware.
- Strong understanding of power sequencing, resets, watchdogs, interrupts, DMA, and linker scripts.
- Hands-on debugging experience with JTAG/SWD, oscilloscopes, and logic analyzers.
- Experience working with embedded Linux systems (Jetson or similar platforms)
- Ability to operate independently and take full ownership in a startup environment.
Desired Job Qualifications:
- Familiarity with flight software architectures and fault detection, isolation, and recovery (FDIR) concepts.
- Experience with RTOS environments such as FreeRTOS, RTEMS, RTLinux, or Embassy
- Experience with radiation-tolerant or space-grade MCUs
- Familiarity with embedded communication protocols such as CAN, RS485, SPI, I2C, UART, SpaceWire, or CCSDS telemetry systems
- Experience with secure boot, image signing, and in-field firmware update strategies
- Experience to CI/CD pipeline or automated build environments for embedded systems
- Experience with supporting protoflight or flight hardware and design reviews
