Join Our Mission

At Omega Technical Services, every role supports a mission that matters. Whether you're advancing national security, driving innovation in nuclear infrastructure, or supporting critical DOE and DoD operations, you’re part of something bigger here.

Omega Technical Services is seeking an experienced Applied Mechanics Engineer to support the design and analysis of a novel advanced nuclear reactor. This position applies engineering principles, modeling, and simulation techniques to evaluate structural and mechanical systems.

The Applied Mechanics Engineer will perform linear and nonlinear static and dynamic analyses involving stress, force, vibration, material plasticity, and thermomechanical behavior. The position will also perform dynamic seismic evaluations of structures, systems, and components, including soil-structure interaction analyses, and compare results against applicable codes, standards, and regulatory requirements.

This position is contingent upon contract award and/or project funding. Candidates may be identified, screened, and submitted prior to award. Employment offers and start dates are dependent upon successful contract award, funding authorization, and client approval.

• Collaborate with a multidisciplinary team of scientists and engineers supporting the design of a novel advanced reactor.
• Perform thermomechanical analyses of reactor internals, including high-temperature graphite and other advanced or exotic materials.
• Perform engineering analyses in accordance with the ASME Boiler and Pressure Vessel Code.
• Conduct seismic evaluations using ASCE 7 and other applicable codes and standards.
• Develop physics-based mathematical models of mechanical, chemical, or electrical systems to support and verify engineering designs.
• Perform structural mechanics evaluations and analyses of structures, systems, and components under normal operating conditions, natural phenomena hazards, and accident conditions.
• Perform linear and nonlinear seismic soil-structure interaction analyses, site-response analyses, and advanced nonlinear structural evaluations.
• Develop models and calculations to evaluate the response of nuclear facilities and systems to seismic ground motion.
• Support safety analyses by simulating postulated accidents and evaluating their structural and mechanical consequences.
• Assist design teams with alternatives analyses, equipment selection and sizing, vendor evaluations, equipment summaries, specifications, drawings, supporting calculations, and engineering design files.
• Document designs through controlled and approved models, drawings, specifications, design descriptions, calculations, and technical reports.
• Verify that designs conform to established requirements and applicable codes and standards.
• Prepare engineering analyses and documentation in accordance with approved engineering processes and quality requirements.
• Apply ASME, ASCE, and other mechanical and structural codes in relation to U.S. Department of Energy requirements for safety-class systems.
• Provide technical leadership, peer reviews, engineering checks, and consultation to other engineers.
• Serve as a primary author of professional technical reports, calculations, and presentations.
• Advise management within assigned areas of technical expertise and represent the organization in technical discussions with project stakeholders.
• Support organizational business-planning and development activities when requested.
• Work independently and collaboratively while maintaining positive and professional relationships under demanding schedules and deadlines.
• Perform other duties as assigned by the Lead Reactor Project Engineer.

• Bachelor of Science degree in Mechanical Engineering or a directly related field from an ABET-accredited program, plus at least eight years of relevant professional experience; or Master of Science degree in Mechanical Engineering or a directly related field from an ABET-accredited program, plus at least six years of relevant professional experience.

• Advanced knowledge of structural dynamics and seismic analysis.
• Experience with linear and nonlinear seismic soil-structure interaction analysis.
• Experience performing site-response analyses.
• Knowledge of advanced seismic probabilistic risk assessment methodologies.
• Knowledge of nuclear systems and advanced reactor technologies.
• Knowledge of the ASME Boiler and Pressure Vessel Code.
• Knowledge of ASCE standards and other applicable mechanical and structural codes.
• Knowledge of engineering design techniques, tools, and principles used to produce technical plans, drawings, blueprints, models, and calculations.
• Ability to apply engineering principles, methods, procedures, and analytical tools to complex technical problems.
• Ability to develop technically sound conclusions by evaluating and combining information from multiple sources.
• Ability to identify existing and potential engineering problems.
• Strong written and verbal communication skills.
• Ability to communicate complex technical information clearly to technical and nontechnical audiences.
• Ability to work effectively both independently and as part of a multidisciplinary team.
• Ability to provide constructive technical input while maintaining professionalism under pressure and tight deadlines.
• Candidate must be a U.S. Citizen. 
  
• Satisfactory results of a pre-employment screening, which includes a drug and breath alcohol test, along with a Motor Vehicle Record check. 
  
• Candidate must be able to obtain and maintain a DOE Security Clearance. 
• Must be available to travel to the Materials and Fuels Complex as required.

• Experience applying ASME Boiler and Pressure Vessel Code, Section III, Division 5.
• Experience performing thermomechanical analyses of high-temperature graphite or other advanced reactor materials.
• Experience supporting advanced nuclear reactor design or analysis.
• Experience performing seismic evaluations in accordance with ASCE 7.
• Experience supporting safety-class systems within a U.S. Department of Energy environment.
• Experience developing advanced seismic probabilistic risk assessment methods.
• Possession of an active DOE/DoD clearance within the past two (2) years is preferred. 
• Previous DOE/NNSA work experience.
