Distinguished Engineer, Reactor Systems

Role overview Set technical direction for the design, integration, analysis, testing, and deployment of advanced reactor systems. This senior technical authority shapes system architecture and engineering standards, resolves difficult cross-disciplinary issues, and advises executive and engineering leaders as the technology moves toward commercialization.

Responsibilities - Define long-term system architecture, design philosophy, and engineering strategy. - Guide requirements, design bases, interfaces, verification plans, and supporting technical records. - Lead resolution of complex issues spanning reactor structures and systems, thermal hydraulics, safety, instrumentation and controls, manufacturing, testing, licensing, and operations. - Establish engineering methods and standards, and assess risks and opportunities affecting development and deployment. - Lead or contribute to integration reviews, technical briefings, design decisions, and compliance assessments against applicable codes and standards. - Mentor engineers and promote rigorous, safety-focused cross-functional work.

Requirements - Bachelor’s or advanced degree in mechanical engineering, nuclear engineering, or a related technical field. - At least 20 years of progressively responsible technical leadership in reactor systems, advanced technology, complex mechanical systems, or a similarly regulated field. - Experience leading major technical scope in a complex engineering program, preferably in nuclear, energy, chemical, oil and gas, or power generation. - Ability to guide engineering decisions across disciplines and communicate complex technical tradeoffs clearly.

Nice to have - Recognized technical contributions such as publications, patents, standards work, or invited presentations. - Experience with formal configuration management or quality systems such as ASME NQA-1 or ISO 9001, and relevant ASME, ANSI, or ASTM codes.

Benefits and work setup - The role is based at a California headquarters, with some travel to project, supplier, fabrication, testing, or installation sites. - The work may occasionally require schedule flexibility or extended hours around project milestones. - Benefits include medical, dental, and vision coverage, paid vacation, and retirement and pre-tax benefit programs.
