The Role We Want You For
The Entry-Level Mechanical Engineer will support the mechanical design of mission-critical facilities, including data centers, advanced manufacturing plants, and other high-availability environments. This is an excellent opportunity for an early-career engineer to gain hands-on experience with complex mechanical systems, high-performance infrastructure, and integrated design project delivery.
In this role, you will work closely with engineers, project managers, and other disciplines to support mechanical design efforts from concept through construction.

  • Participate in construction administration tasks, including RFI responses, submittal reviews, and field observations.
  • Learn and apply ICC, ASHRAE, NFPA and other relevant code series and standards.
  • Develop technical skills through mentorship, project exposure, and continuing education.

Requirements
  • BS degree in Mechanical Engineering from an ABET institution required.
  • 0-3 years of experience in Mechanical Engineering; internship or co-op experience in mission-critical, data center, or industrial projects is a plus.
  • EIT certification or ability to obtain within first year of employment required.
  • Familiarity with AutoCAD and Revit; exposure to load calculations software such as Trane Trace, Carrier HAP or similar; exposure to CFD modeling software such as Ansys Fluent, Cadence Reality or similar is a plus.
  • Ability to break down complex challenges and communicate clear, actionable solutions.
  • Highly organized with ability to manage and pivot between concurrent projects.
  • Strong communication, collaboration, and problem-solving skills, with a willingness to learn in a fast-paced environment.

Some Things You Should Know
  • No other builder can offer the collaborative design-build approach that Clayco does.
  • We work on creative, complex, award-winning, high-profile jobs.
  • The pace is fast!
