About the role
As an Embedded Software Engineer on the Core Platform team in Boston, you will play a critical role in building hardware‑in‑the‑loop (HIL) test infrastructure that validates the functional safety components powering our next generation of humanoid robots. In this position, you will work at the intersection of hardware, software, and systems integration, creating realistic test environments that allow the team to evaluate system behavior before it ever reaches the robot. You will collaborate closely with firmware and hardware engineers to design test fixtures, automate black-box testing, and build the harnesses that simulate real robot inputs and stress the system in meaningful ways.
Responsibilities
- Build and maintain HIL test environments specifically for functional safety hardware and associated embedded components.
- Engineer and integrate test fixtures, laboratory bench environments, and the necessary infrastructure to emulate complex robotic behaviors.
- Create sophisticated software and firmware for automation, utilizing Python-based tools and embedded code for specialized test hardware.
- Leverage Raspberry Pi, microcontrollers, and IoT platforms to generate high-fidelity system interfaces and realistic stimuli.
- Execute black-box validation by interfacing the safety computer with simulated inputs, performing fault injection, and analyzing system resilience.
- Partner with firmware and hardware teams to investigate failures, optimize test coverage, and streamline safety-critical validation processes.
- Contribute to the development of scalable infrastructure that enables automated, future-proof validation for safety-related systems.
Requirements
- 3+ years of experience in embedded systems, test engineering, robotics, mechatronics, or a similar hands-on technical field.
- Strong practical skills across both hardware and software, with the ability to wire systems, build fixtures, and write automation code.
- Proficiency in Python and comfort working with embedded software or firmware used for internal tools and test systems.
- Hands-on experience with Raspberry Pi, microcontrollers, IoT devices, or similar prototyping and test platforms.
- Experience debugging integrated systems at the bench using lab equipment and iterative hardware/software investigation.
- A builder/tinkerer mindset with strong curiosity, good judgment, and enjoyment of making complex systems work in the lab.
- Interest in robotics and safety-critical systems, with the ability to thrive in a fast-moving, highly collaborative engineering environment.
Benefits
Additional Information
Here at Humanoid, we believe in a future where robots amplify human potential. That's why we've set out on a mission to build the world's most capable, commercially-scalable, and safe humanoid robots. We're bringing that mission to life with HMND‑01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we're growing the team to take it even further.
