Firmware Engineer Jobs in Seattle, WA (NOW HIRING)

AIM builds autonomy for the real world - robots that move mountains. Our systems fuse software, hardware, robotics, and mission-critical infrastructure into ruggedized, safety-critical machinery operating on jobsites across the world. We replace decades of manual, error-prone, high-risk work with intelligent machines that reshape how earthmoving is done.

Firmware is the foundation of everything we ship. It connects compute to control, sensors to decisions, and safety systems to real-world actuation. Our firmware runs on embedded systems inside heavy machinery - operating under real-time constraints, harsh environments, and zero tolerance for failure.

We’re scaling fast, building our Generation 2 hardware platform, and need firmware that is deterministic, observable, and production-ready at fleet scale. Learn more about AIM

You’re a firmware engineer who thrives at the boundary between hardware and software. You write clean, efficient, reliable C++ code that interacts directly with real-world systems - and you care deeply about correctness, timing, and failure modes.

You’re comfortable working close to the metal: microcontrollers, embedded Linux systems, device drivers, communication buses, and hardware interfaces. You debug with oscilloscopes, logs, and intuition. You understand that firmware is not just code - it’s the behavior of the machine.

You take ownership of systems end-to-end - from hardware bring-up to production deployment - and you design firmware that is testable, observable, and resilient in the field. You have strong judgment about trade-offs between performance, safety, and complexity.

You want to work on systems where reliability is non-negotiable and where your code directly controls machines operating in the real world.

We’re building the firmware foundation for autonomous heavy equipment. That means solving hard problems:

• real-time control loops and deterministic execution
• reliable communication across CAN, Ethernet, and serial interfaces
• hardware variability across machines and environments
• safety-critical systems with fail-safe behavior
• debugging in high-noise, high-vibration, high-entropy environments
• firmware update, configuration, and observability at fleet scale

We’ll iterate quickly, confront failures directly, and build systems that work not just in the lab - but in dust, heat, vibration, and real customer operations.

If that excites you - you’ll thrive here.

As a Senior Firmware Engineer, you will design and build the core systems that power AIM’s autonomous machines and global fleet operations.

• Design and implement firmware for AIM’s Generation 2 hardware platform using C++.

• Familiarity with HIL testing, validation frameworks, or hardware test automation.
• Experience working in high-reliability or high-entropy environments.

• You design firmware that is simple, deterministic, and highly reliable.
• You think in terms of systems - not just code - and understand machine behavior end-to-end.
• You bring a strong safety mindset and anticipate failure modes before they occur.
• You debug issues others can’t - across firmware, hardware, and system interactions.
• You raise engineering rigor through clarity, ownership, and high standards.
• You connect firmware decisions directly to machine performance and customer outcomes.

• Opportunity to build firmware that directly controls autonomous heavy machinery in the real world.
