HVAC Design Engineer – Mission-Critical Cooling & Cleanrooms

Remotely

Full-time

We are an employee-owned engineering practice dedicated to resilient infrastructure. For over two decades, our specialists have delivered reliable cooling, ventilation, and energy solutions for hyperscale tech firms, vaccine manufacturers, and university research hubs. We invest aggressively in new tools, continuous learning, and a flexible work culture to keep our engineers at the forefront of HVAC innovation.

Key Responsibilities

- Model complex airflow, temperature, and humidity profiles using CFD tools such as 6SigmaET and ANSYS..

- Engineer N+1 mission-critical cooling architectures for servers exceeding 30 kW/rack—built to survive utility outages..

- Specify and size chillers, CRAH/CRAC units, AHUs, VAV boxes, and filtration stages for ISO 14644 Class 5 cleanrooms..

- Design ammonia and CO₂ industrial refrigeration loops in line with IIAR and OSHA PSM/RMP..

- Calculate psychrometric performance at extreme ambient conditions (-20 °F to +120 °F)..

- Produce sealed ductwork and pressured plenum layouts that eliminate cross-contamination in pharma suites..

- Coordinate pipe-stress analysis, seismic bracing, and vibration isolation with structural teams..

- Generate construction documents, control sequences, and commissioning scripts that cut energy use by 18 %+.

- Mentor junior engineers, review submittals, and respond to RFIs throughout the project lifecycle..

- Collaborate in a cloud-based BIM environment—hybrid/remote collaboration is fully supported..

Minimum Requirements

- Bachelor’s (or higher) in Mechanical Engineering or Architectural Engineering..

- 6 + years designing HVAC systems for data centers, semiconductor fabs, biotech labs, or heavy industry..

- Proficiency in Revit MEP, AutoCAD Plant 3D, and at least one CFD platform (6SigmaET, FloTHERM, or equivalent)..

- Working knowledge of ASHRAE 90.4, ASHRAE 170, NFPA 70, IIAR 2, SMACNA, and ICC mechanical codes..

- Demonstrated success sizing pumps, chillers, cooling towers, and pipe networks via HAP or PipeFlo..

- Ability to stamp drawings as a licensed PE in at least one U.S. state—or eligibility within 12 months..

- Clear, concise written communication suitable for specifications, reports, and client presentations..

Preferred Extras

- Experience with district energy or central utility plant (CUP) optimization..

- Familiarity with ISO 8573 compressed-air quality classes..

- LEED AP or Certified Energy Manager credential..

- Expertise in low-GWP refrigerants and carbon-reduction road-maps..

Why This Role Stands Out

You’ll tackle projects where a single degree of temperature deviation can cost millions—meaning your designs truly matter. Our multidisciplinary team moves fast, leverages advanced analytics, and shares knowledge openly. Expect a dynamic workload, support for professional licensure, and the autonomy to work from any U.S. time zone.
