Senior Embedded Firmware Engineer (Safety-Critical Systems)

Location: San Francisco CA Los Angeles CA Washington DC
Training Requirement: Candidates must complete an initial 1-month onsite training program in Kearneysville WV before transitioning to their assigned office location.

About the Role

We are seeking a Senior Embedded Firmware Engineer to develop firmware for a safety-critical embedded system integrated with advanced aerospace and defense hardware. This role offers end-to-end ownership of firmware development from board bring-up and driver implementation through qualification testing and deployment.

Youll work closely with hardware engineers in a highly collaborative hands-on environment where rapid iteration reliability and testability are essential.

Responsibilities

• Design develop and maintain embedded firmware for ARM Cortex-M or comparable microcontroller platforms
• Own firmware architecture including device drivers state machines communication interfaces command handling and programming workflows
• Create host-testable firmware and simulation frameworks that enable validation without requiring target hardware
• Collaborate with hardware engineers on board bring-up peripheral integration timing analysis and debugging
• Implement and validate communication protocols and peripheral interfaces
• Support environmental qualification activities including thermal EMC and vibration testing
• Define and maintain firmware safety requirements verification strategies and supporting documentation
• Contribute to firmware reliability security maintainability and performance improvements

Required Qualifications

• 5 years of professional embedded firmware development experience
• Strong experience with ARM Cortex-M or similar embedded platforms
• Advanced proficiency in C C or Rust
• Experience with:
• Interrupts DMA clocks timers memory maps linker scripts and low-power modes
• I²C SPI UART and USB communications
• Hardware debugging using oscilloscopes and logic analyzers
• State machine design for real-world embedded systems
• Board bring-up and low-level hardware integration
• Host-based testing and firmware validation methodologies
• Professional written and verbal English communication skills

Preferred Qualifications

• Embedded Rust experience including Embassy embedded-hal RTIC defmt probe-rs or nostd development
• Modern embedded C (C17/C20)
• Experience with FreeRTOS Zephyr or asynchronous embedded architectures
• Safety-critical firmware development experience (ISO 26262 DO-178C IEC 61508 or similar)
• Bootloader DFU secure boot or OTA update implementation
• UAV drone FPV MAVLink INAV or related aerospace systems experience
• Experience with C FFI or SDK integration

Work Environment

• Collaborative hardware-focused engineering culture
• Frequent interaction with real hardware and rapid development cycles
• High degree of technical ownership and responsibility
• Focus on quality reliability testability and safety

Additional Requirements

• Ability to complete a mandatory 1-month onsite training period in Kearneysville West Virginia
• Ability to work onsite from San Francisco Los Angeles or Washington DC following training
• Must be legally authorized to work in the United States
