Job Title:

Mechanical Engineer – HVAC & Plumbing (Mid-to-Senior Individual Contributor)

We are seeking a Mechanical Engineer – HVAC & Plumbing (Mid‑to‑Senior Individual Contributor) to support the design and development of systems for technically complex, mission‑critical federal facilities. This is a hands‑on role focused on owning HVAC and plumbing system design, calculations, and Revit‑based construction documentation within a collaborative, fast‑paced team environment. Ideal candidates are detail‑oriented engineers who thrive in production‑focused work and are eager to contribute to high‑impact projects across VA, DoD, and federal infrastructure.

• Independently design HVAC and plumbing systems with direct ownership of system layouts, calculations, and construction documentation.
• Perform mechanical calculations, including load calculations, equipment sizing, pump calculations, and general HVAC and plumbing system calculations.
• Validate calculation inputs and outputs, applying sound engineering judgment when results appear inconsistent or incorrect.
• Produce high‑quality construction documents in Revit, including models and drawings that clearly reflect personally designed systems.
• Support multiple projects concurrently in a lean team environment, managing priorities and deadlines effectively.
• Coordinate closely with architecture, electrical, and other engineering disciplines to ensure fully integrated designs.
• Participate in short site visits for field verification, existing system assessment, and confirmation of design conditions.
• Actively contribute to the production of construction documents, details, and specifications, rather than focusing solely on coordination or oversight.
• Clearly articulate systems personally designed, calculations personally performed, and drawings personally produced when collaborating with internal and external stakeholders.
• Collaborate with project teams to support mission‑critical federal and defense facilities where HVAC and ventilation requirements differ significantly from commercial buildings.
• Maintain accountability for meeting project deadlines while working within a laid‑back but performance‑driven culture.
• Provide occasional client‑facing support during site visits or meetings, particularly for engineers with strong presentation and communication skills.

• Bachelor’s degree in Mechanical Engineering (BSME) or a related field preferred.
• 5–10+ years of recent, hands‑on HVAC and plumbing design experience, with more senior candidates considered only if they are clearly still performing active design, calculations, and Revit production.
• Demonstrated experience personally designing both HVAC and plumbing systems (not HVAC‑only with limited plumbing exposure).
• Proven ability to perform mechanical load modeling and mechanical calculations, including loads, equipment sizing, and pump calculations.
• Strong proficiency with Revit MEP, including active production of construction documents, drafting, and modeling in the current or most recent role.
• Direct ownership of drawing production in Revit, not limited to coordination, redlining, or CAD‑only work.
• Hands‑on HVAC and plumbing design execution clearly evidenced through a portfolio or resume that shows personally produced construction documents and detailing work.
• Experience working across multiple concurrent projects rather than a single long‑term program.
• EIT registration required as a baseline credential.
• Ability to quickly contribute without the need for Revit training or extensive onboarding in construction documentation workflows.
• Capability to support technically complex, high‑impact federal and mission‑critical facilities where HVAC and ventilation requirements differ from commercial projects.
• Strong engineering judgment and problem‑solving skills, especially in validating and troubleshooting calculation results.
  
  Effective communication skills, with the ability to clearly explain design decisions, calculations, and documentation to project teams and stakeholders.

• Professional Engineer (PE) license preferred but not required; licensure does not…
