MSTS is required by DOE directive to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants offered employment with MSTS are also subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment. In addition, Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship, at least 18 years of age. Reference DOE Order 472.2, "Personnel Security". If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Department of Energy Q Clearance (position will be cleared to this level). Reviews and tests for the absence of any illegal drug as defined in 10 CFR Part 707.4, "Workplace Substance Abuse Programs at DOE Sites," will be conducted.  Applicant selected will be subject to a Federal background investigation, required to participate in subsequent reinvestigations, and must meet the eligibility requirements for access to classified matter. Successful completion of a counterintelligence evaluation, which may include a counterintelligence-scope polygraph examination, may also be required.

MSTS is seeking a Senior Autonomous Systems Engineer to design and deploy next-generation control systems that bridge industrial automation, embedded hardware and intelligent algorithms. This role goes beyond traditional controls combining hands-on system development with modern approaches to sensing, data and adaptive optimization. You will work across the full stack, from selecting hardware and programming controllers to integrating AI/ML techniques that enable closed-loop performance improvements. The ideal candidate is equally comfortable at the bench and in code, thrives in multidisciplinary environments and is motivated to build systems that operate reliably in complex real-world conditions.

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.

Key Responsibilities

• Architect and build end-to-end control systems integrating PLCs, embedded platforms, sensors and actuators for real-world applications.
• Develop and implement control logic and firmware across industrial and embedded environments, from low-level interfaces to supervisory control.
• Translate systems goals into close-loop solutions, combining sensing, signal processing and control strategies to achieve reliable performance.
• Partner with AI/ML specialists to optimize system behavior, enable adaptive control and detect anomalies.
• Prototype, test and refine systems in the lab and field, troubleshooting across hardware and software boundaries to ensure robust operation.
