Apply for Electronics/RF Lab Technician

Cambridge Terahertz is one of the world’s only companies pushing the boundaries of Terahertz technology, a true “white space” technology at the intersection of wireless, advanced sensing, and custom silicon. Based on a decade of research at MIT, we’re now based in Santa Clara, CA and backed by top-tier investors including Felicis and Amazon, with over $15M raised and five active government contracts. With a THz silicon design team and multiple generations of imaging prototypes, we’re among the few with an FCC license to operate at THz, and have been featured in CNBC, MIT News and Techcrunch. Our passionate, world-class team thrives on hard problems, rapid learning, and applying cutting-edge technology towards products that have real impact. Our core mission is to drive societal change through next-generation physical security and weapons detection. By shrinking airport-grade security scanners into scalable devices that work unobtrusively in everyday settings, we’re tackling the urgent, unsolved challenge of proactive weapons screening - making schools, venues, and public spaces safer without compromising privacy or convenience. The work we do at Cambridge Terahertz doesn’t just break technical barriers; it saves lives and improves communities. If you want to invent in an environment where breakthroughs are expected, the bleeding edge is comfortable, and frontier tech is your day job, join us and help build the future of security, sensing, and real-world impact.
