<div> <h3>I/O Subsystem Engineer</h3>Are you a control systems junkie with a passion for elegant protocols and ruthless clarity in abstraction boundaries?We’re looking for a technical systems-minded engineer who lives and breathes protocols — not to design subsystems in isolation, but to lead the charge on what building control integrations matter, when they matter, and how they should be built across teams.About PassiveLogic®PassiveLogic 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. About the RoleThis 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. What you’ll doAs our I/O Subsystem Engineer, you’ll be the nerve center for connectivity between our digital twin-driven control stack and the fragmented world of building control protocols. You’ll:Own PassiveLogic’s protocol roadmap: Decide which standards we support next and when, based on our product roadmap. Scope and lead integration efforts: Interface real-world systems to our autonomy platform through intelligent I/O and networks.Coordinate protocol implementations: Work with product, applications, hardware, and OS teams to drive protocol timelines, implementation, and integration.
