Senior Electrical Engineer

Mission Support and Test Services, LLC (MSTS) manages and operates the Nevada National Security Site (NNSS) for the U.S. National Nuclear Security Administration (NNSA). 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, while acting as environmental stewards for 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 below ground, on the ground, and in the air.

• MSTS offers full‑time employees highly competitive salaries and benefits packages, including medical, dental, and vision insurance; a pension and a 401(k); paid time off and 96 paid holidays; relocation assistance (if located more than 75 miles from the work location); tuition assistance and reimbursement; and more.
• MSTS is a limited liability company consisting of Honeywell International Inc. (Honeywell), Jacobs Engineering Group Inc. (Jacobs), and HII Nuclear Inc.

MSTS is seeking a Senior Electrical Engineer for our Special Technologies Laboratory (STL) to support advanced R&D focused on understanding, exploiting, and protecting operational technology systems. This role blends hands‑on engineering with adversarial thinking—evaluating how systems can fail, be disrupted, or subverted, and developing sensing and monitoring approaches to detect and mitigate those risks. The engineer will work across embedded systems, industrial controls, and custom instrumentation in a fast‑paced, multidisciplinary environment.

The ideal candidate is technically strong, curious, and creative—someone who enjoys probing system weaknesses, building novel solutions, and contributing to defensive engineering efforts. STL is located in Santa Barbara, California and serves as a key satellite location within the NNSS, responsive to NNSA nuclear security mission requirements and broader national security objectives.

• Assess vulnerabilities in operational technology systems, including industrial controls, embedded devices, and sensor networks, using analytical and hands‑on approaches.
• Design and develop sensing and data collection systems to monitor system behavior, detect anomalies, and validate system integrity.
• Develop and test techniques to emulate, induce, and detect system faults or disruptions, supporting red‑team and resilience efforts.
• Implement and integrate embedded and control systems solutions, including firmware, interfaces, and communication with industrial hardware.
• Collaborate with multidisciplinary teams to translate findings into actionable improvements in system design, monitoring, and protection.
• Perform other duties assigned by management.

• Bachelor’s degree in an engineering program accredited by the Accreditation Board for Engineering and Technology (ABET) for Civil, Mechanical, or Electrical engineering degrees, or a calculus‑based STEM bachelor’s degree in engineering. Alternatively, for architects, certification from NCARB, or a Professional Engineer license. Plus at least 5 years of relevant experience, with demonstrable technical specialization or cross‑disciplinary knowledge (graduate research experience may be recognized).
• Demonstrated desire to learn and innovate.
• Demonstrated ability to analyze and troubleshoot complex electro‑mechanical systems, with curiosity for identifying system vulnerabilities across failure modes.
• Self‑motivated and able to complete assigned tasks with minimal supervision.
• Strong time‑management skills; well organized, maintaining safe work habits; and a broad range of technical interests.
• Excellent oral and written communication skills, including the ability to write reports and technical documents.
• Primary work location:
  Special Technologies Laboratory (STL) in Santa Barbara, CA.
• Work schedule will be negotiated; employees may work 5‑8, 9‑80, or 4‑10 work‑weeks.
• Pre‑placement physical examination, including a drug screen, is required. MSTS maintains a substance abuse policy that includes…
