Mechanical Project Engineer

Thompson & Litton Inc
Princeton, WV Full Time
POSTED ON 9/4/2026
AVAILABLE BEFORE 11/2/2026

Collaborative Design. Technical Excellence. Community Impact.

Are you a mechanical professional who loves the 'puzzle' of a complex building system? Thompson & Litton is seeking a self-motivated Mechanical Engineer or Designer to join our multi-disciplined team. Whether you are calculating high-efficiency HVAC loads or designing life-safety fire protection systems, you'll be part of a collaborative group that values your creative input and your professional growth.

The Role: From Concept to Completion

As part of our mechanical engineering group, you will be involved in the full scope of design for commercial, industrial, and institutional projects. You will:

  • Design & Draft: Lead the production of comprehensive mechanical design packages, including HVAC, plumbing, and fire protection plans.
  • Analyze & Optimize: Perform critical calculations for HVAC loads, energy usage, and life-cycle costs to provide sustainable solutions.
  • Collaborate in the Field: Conduct site visits for renovations and additions, gathering the 'ground-truth' data needed for successful designs.
  • Lead Project Delivery: Generate project specifications, written reports, and system condition assessments.
  • Support Construction: Act as a bridge during the construction phase, managing RFIs, submittal reviews, and field assessments.

What You Bring

  • Experience: 3–5 years in mechanical system design (HVAC, Plumbing, and Fire Protection) within commercial or institutional sectors.
  • Education: B.S. in Mechanical Engineering from an ABET-accredited program is preferred.
  • Technical Knowledge: A strong working knowledge of mechanical codes and standards (including ICC, ASHRAE, and NFPA).
  • Project Skills: A proven ability to deliver projects on time and on budget while communicating effectively with diverse project teams.

The T&L Advantage

  • Flexible Work Environment: We work where the work needs us—in the office, from home, in the field, and in the community. We offer great flexible hours to support your life outside of work.
  • Mentorship Culture: We are looking for people who are passionate about encouraging others. At T&L, your mentorship of junior staff is as valued as your technical design skills.
  • Broad Project Scope: From K-12 schools to industrial facilities, you will work on a wide variety of building types and delivery methods.
  • Focus on Potential: We value the depth of your experience and your professional goals just as much as the number of years on your resume.

If you're excited about making an impact and want to join an award-winning team, we want to hear from you!
