Senior Firmware Engineer Jobs in Seattle, WA (NOW HIRING)

$180000 - $230000 per year | Redmond, WA | Hybrid | Permanent

We are partnering with a rapidly growing robotics company building autonomous systems for heavy machinery and demanding industrial environments.

Their technology brings together embedded software, robotics, advanced hardware and mission-critical infrastructure to automate work traditionally performed through manual and high-risk operations.

The company is developing its next-generation hardware platform and is looking for an experienced firmware engineer to help build the foundation connecting onboard computing, sensors, control systems and real-world machine actuation.

Build firmware that directly controls autonomous heavy machinery

Take ownership of a next-generation embedded hardware platform

Work across firmware, electrical engineering, robotics, autonomy and field operations

Solve complex real-time and safety-critical engineering problems

Own systems from initial hardware bring-up through production deployment

Help shape firmware architecture, standards and engineering practices

See your work operate on real equipment—not just behave nicely inside a laboratory

Competitive compensation, equity, medical, dental and vision coverage

401(k), life insurance and opportunities to visit customer jobsites

We are seeking a Senior Firmware Engineer to design and build the embedded systems powering autonomous machines and fleet operations.

You will develop production-quality embedded C++ software that connects computing platforms to sensors, actuators, ECUs and safety systems. This position requires an engineer who can operate comfortably at the boundary between hardware and software and who understands that firmware ultimately determines how a physical machine behaves.

You will own systems from board bring-up and driver development through testing, deployment, observability and field troubleshooting.

• Design and implement firmware for a next-generation embedded hardware platform
• Develop low-level drivers, hardware abstraction layers and system services
• Build interfaces for sensors, actuators, ECUs and other machine components
• Work with CAN, Ethernet, SPI, I²C, UART and other communication protocols
• Develop deterministic real-time and near-real-time control paths
• Write clean, efficient and testable embedded C++ code
• Implement watchdogs, error handling and fail-safe behavior
• Design firmware that remains reliable through hardware faults, communication loss and environmental variability
• Build logging, tracing, telemetry and embedded diagnostic capabilities
• Lead firmware bring-up for new boards, daughterboards and related hardware
• Partner with electrical and mechanical engineers to validate designs and interfaces
• Diagnose difficult issues spanning firmware, hardware and system integration
• Perform root-cause analysis on failures found during testing or field deployment
• Optimize timing, memory consumption and CPU utilization
• Support hardware-in-the-loop testing, regression testing and field validation
• Improve firmware CI/CD pipelines, testing frameworks and development workflows
• Establish standards for firmware safety, reliability and maintainability
• Mentor other engineers on embedded development and debugging practices

• Bachelor’s degree in Computer Engineering, Electrical Engineering, Robotics or equivalent professional experience
• 5+ years of firmware or embedded-systems development experience
• Strong embedded or systems-level C++ programming experience
• Experience developing firmware for microcontrollers or embedded Linux systems
• Experience with CAN, SPI, I²C, UART, Ethernet or similar interfaces
• Strong debugging skills across hardware and software boundaries
• Experience delivering production-quality firmware for real-world products
• Understanding of reliability, failure modes and defensive system design
• Ability to work effectively across firmware, hardware and mechanical engineering teams

• Experience with robotics, autonomous systems or heavy equipment
• Experience developing safety-critical or real-time embedded systems
• Familiarity with an RTOS or real-time scheduling concepts
• Hardware bring-up and board-level debugging experience
• Experience with bootloaders, OTA updates or secure firmware updates
• Experience building embedded logging, tracing or telemetry systems
• Hardware-in-the-loop testing or automated hardware-validation experience
• Experience supporting products deployed in unpredictable or physically demanding environments
• Background improving firmware testing, CI/CD or release processes
