About the role

Navarro Research & Engineering is seeking a Senior Mechanical Design Engineer specializing in designing and optimizing piping and mechanical systems within process-control environments that handle liquids or gases. This role demands extensive experience in fluid dynamics, equipment specification, and structural analysis.

Key Responsibilities

  • 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.

Education & Certification

  • 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.

Additional Requirements

  • Ability to obtain and maintain a DOE Q-level security clearance.

Benefits

  • Health Care Plan (Medical, Dental & Vision)

  • Retail Retirement Plan (401k, IRA)

  • Life Insurance (Basic, Voluntary & AD&D)

  • Paid Time Off (Vacation & Public Holidays)

  • Short Term & Long Term Disability
