• Participate in the development and execution of test plans for prototype components and systems, ensuring robust performance and reliability by providing recommendations and solutions to problems of limited complexity.
• Contribute to the analysis for components and participate in providing supporting safety and engineering documentation to ensure compliance with process requirements and operational excellence.
• Present technical findings and participate in engineering design reviews to drive project success.
• Prepare technical documents and author clear, concise technical presentations.
• Participate in the development and implementation of solutions for commissioning, maintenance, and calibration procedures for well-defined subsystems, including analyzing, summarizing, and presenting data results.
• Contribute to the development of detailed plans, schedules, and budgets for project activities under general direction to support efficient project execution.
• Collaborate closely with team members to ensure the successful integration and proper functioning of commissioned systems.
• Perform other duties as assigned.

Additional Job Responsibilities (At the SES.2 Level)

• Work under limited direction with moderate responsibility, use comprehensive knowledge, and exercise independent judgment to determine methods and recommend improvements within established frameworks and contribute to the fulfillment of project and organizational goals.
• Contribute to the scope, schedule, budget, and quality of moderately complex to complex engineering work and provide regular updates to management to ensure alignment with project objectives.
• Provide solutions to moderately complex engineering problems and contribute to the development of enhanced system capabilities, leveraging comprehensive knowledge of systems engineering processes.
• Independently determine methods, techniques, and evaluation criteria for contributing to the hardware design and function of commissioning instrumentation and tooling under limited direction.

Requirements & Tech Stack

• Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
• Bachelor's degree in Mechanical Engineering or related discipline, or an equivalent combination of education and relevant experience.
• Fundamental knowledge of and experience with the design, commissioning, operation, and maintenance of limited complexity systems.
• Fundamental knowledge of common data analysis techniques, statistics, and/or systems engineering.
• Basic operational experience with, and fundamental knowledge of machine structural design, assembly, or control design processes.
• Foundational understanding of design principles and their practical application.
• Experience applying established process engineering and workflow optimization.
• Experience using standard project management practices to drive project success.
• Experience participating with multidisciplinary teams to solve technical problems of limited complexity, while working under general direction.
• Sufficient verbal and written communication skills to collaborate effectively in a multidisciplinary team environment and present and explain technical information.

Additional Qualifications (At the SES.2 Level)

• Comprehensive knowledge of moderately complex to complex precision hardware and mechanical system design.
• Comprehensive knowledge of and experience with design, commissioning, operation, and maintenance of mechanical systems.
• Broad experience applying systems engineering processes to mechanical design and testing.
• Broad experience in identifying, defining, and solving moderately complex to complex multi-disciplinary problems in a timely, cost-effective manner.
• Proficiency and broad experience participating as an active member of design review processes, and/or informally mentoring others in areas of technical specialty.
• Demonstrated ability to exercise independent judgment in determining optimal techniques, methods, and evaluation criteria for addressing assigned technical problems, interacting with management, and providing input on technical issues for specific projects.
