Mechanical Design Engineer II (HVAC Focus)

Capitol Engineering Group is looking for a driven and talented Mechanical Design Engineer II to take a leadership role in our most complex HVAC engineering projects. This isn’t just a design role— it’s an opportunity to become a technical leader who defines project success, solves high‑level challenges, and directly mentors the next generation of engineers.

What You’ll Do:

  • Lead the technical execution of complex HVAC engineering projects, ensuring designs are innovative, compliant, and cost‑effective.
  • Perform and validate advanced engineering calculations, including detailed heating/cooling load analysis, equipment sizing, and hydraulic and friction loss calculations.
  • Develop specifications and enforce high‑quality standards for design review and inspection across the team.
  • Identify, troubleshoot, and implement efficient, novel solutions to complex, non‑routine engineering challenges that impact project direction.
  • Act as a direct mentor and technical Seam for junior engineers, directing workflow, resolving technical roadblocks, and fostering their professional growth.

What We’re Looking For:

  • 3+ years of progressive experience in mechanical design engineering, specifically focused on HVAC systems.
  • Deep expertise in advanced engineering calculations (loads, sizing, hydraulics) and developing comprehensive system specifications.
  • Proven ability to manage technical aspects of projects, work of others, and effectively resolve complex technical issues.
  • Bachelor’s degree in Mechanical Engineering or a related field.
  • Engineer‑in‑Training (EIT) is a plus.

We offer a challenging and supportive environment where you will have the autonomy to make high‑impact decisions and the resources to continuously grow your expertise. You will be part of a team that is not just building projects, but building careers.
