Hardware Test Systems Engineer

Develop and validate software, firmware, and hardware, building robust automated test systems that accelerate reliability, scalability, and deployment of complex embedded technologies.

Passive Logic is the first fully autonomous platform for buildings. We’ve reinvented the fundamental principles of automation to democratize technology, optimize buildings, and reduce the world’s carbon footprint. We are a team of technologists, engineers, and creatives dedicated to making a sustainable impact through real-world solutions.

We are looking for team members who have a passion for technology and want to work on cutting‑edge problems with real‑world solutions. Our culture is built on bringing together the most talented engineers, thinkers, and creatives—backed by the world’s leading investors—working together to make the future a reality.

This is a career‑defining opportunity to play a crucial role in a hyper‑scale AI company that is transforming the future of autonomous systems, energy, and the built environment.

As our Hardware Test Systems Engineer, you will be responsible for verifying and validating the functionality of our low‑power sensors, AI‑driven controllers, and other custom hardware across the operational regimes.

• Design and build custom hardware/software test fixtures and systems that electrically stimulate, measure, orchestrate, and validate Passive Logic Hive, Cell, and Sense product families.
• Test, report bugs, and debug mechanical, electrical, firmware, and software problems alongside our development teams.
• Evangelize new testing methodologies, best practices, and tools with goals to continuously improve test coverage through both manual and automated processes.
• Participate in cross‑functional teams to support engineering test, bringup, and deployment of our Autonomous Platform for Buildings.
