Nuclear Security involves developing policies, managing security programs, and overseeing nuclear safety at high-level facilities. In contrast, a Nuclear Security Guard primarily performs physical security duties, patrols, and access control at nuclear sites. Both roles require security training, but Nuclear Security professionals focus on strategic security management, while guards focus on on-the-ground security operations.

Our mission is to help ensure the security of the United States and its allies by providing high-hazard experimentation and incident response capabilities through operations, engineering, education, field, and integration services and by acting as environmental stewards to the Site's Cold War legacy. Our vision is to be the user site of choice for large-scale, high-hazard, national security experimentation, with premier facilities and capabilities below ground, on the ground, and in the air. Our 2,750+ professional, craft, and support employees are called upon to innovate, collaborate, and deliver on some of the more difficult nuclear security challenges facing the world today.
The Special Technologies Laboratory (STL) is seeking a highly capable Principal Technologist to support the assembly, fabrication and deployment of advanced prototype systems in a fast-paced R&D environment. This role blends hands-on technical work with problem-solving across mechanical and electrical domains.

Success in this role requires adaptability, craftmanship and curiosity.
Located in Santa Barbara, California, the Special Technologies Laboratory is a key satellite location within the NNSS and is responsive to NNSA nuclear security mission requirements and broader national security objectives. At STL "problem solving is in the DNA," using a diverse team of experts composed of scientists, engineers, technicians, facilities specialists, academic collaborators, and professional support staff.
