About the role
- Lead the design, construction, and maintenance of facility piping systems, including rigorous component sizing and equipment selection (pumps, motors, heaters, blowers, valves, etc.).
- Model pressure, flow, and thermal effects (steady‐state and transient) using CFD, FEA, and related tools; validate piping integrity under static and dynamic loads, and perform pipe-stress/structural analyses.
- Develop, review, and red-line mechanical and piping drawings, plans, and specifications derived from engineering calculations; ensure compliance with codes, standards, and regulatory requirements.
- Plan, schedule, conduct, and coordinate detailed phases of engineering work for major projects or for entire projects of moderate scope; prepare ROMs and detailed cost estimates, compile equipment specifications, and generate procurement documentation.
- Participate in safety reviews, quality-assurance activities, training sessions, and regulatory audits; drive continuous improvement by integrating emerging technologies and best practices.
- Produce technical reports, literature reviews, and progress updates; present findings and status briefings to stakeholders and senior management.
- Direct the work of technical support staff and mentor junior engineers in mechanical and fluid-system design; guide troubleshooting and modifications to resolve equipment malfunctions.
- Perform additional related tasks as assigned.
Requirements
- Five to twelve (5 – 12) years of mechanical design-engineering experience with a strong focus on piping and fluid systems (industrial liquid or gas processes).
- Demonstrated expertise in pressure-drop calculations, fluid-flow optimization, and equipment sizing/selection.
- Proficiency in static and dynamic piping analyses, including pipe-stress and support-structure calculations.
- Prior experience in highly regulated or process-driven industries (nuclear, chemical processing, oil & gas, HVAC, etc.).
- Familiarity with relevant codes and standards (ASME or equivalent) and proven ability to integrate them into efficient designs.
- Strong in fluid mechanics, thermodynamics, and materials science.
- Proven history of analytical, problem-solving, and project-management skills; effective oral and written communication; collaborative mindset when working with cross-functional teams.
- Bachelor’s degree in Mechanical Engineering (or a related field) from an accredited institution – or equivalent combination of education and experience.
- Professional Engineer (PE) licensure and/or certifications in project management or quality are advantageous but not required.
- Ability to obtain and maintain a DOE Q-level security clearance.
- US citizenship required.
Benefits
- Health Care Plan (Medical, Dental & Vision)
- Retirement Plan (401k, IRA)
- Life Insurance (Basic, Voluntary & AD&D)
- Paid Time Off (Vacation & Public Holidays)
- Short Term & Long Term Disability
