Refrigeration Engineer II

Are you a licensed Mechanical Engineer who thrives on solving complex refrigeration challenges and leading projects from concept through construction? At HFA, you won’t just design systems—you’ll shape high-performance refrigeration solutions that power commercial/retail environments across the country.

In addition, our refrigeration team has opportunities with cold storage through strategic relationships and expanding service opportunities in which the successful candidate would be involved with.

We’re looking for a Refrigeration Engineer who can lead small client teams, take ownership of projects, and confidently navigate both traditional and emerging refrigeration technologies.

The successful candidate will provide mentorship to less experienced designers and make technical contributions. This role has potential for growth to become a signing engineer in multiple states as professional development and confidence is built over a short period of time.

• Take the lead on small projects or key portions of larger projects, guiding clients and internal teams through successful project delivery.
• Design and draft commercial refrigeration systems, including isometric layouts for small to mid-sized projects.
• Select and size refrigeration equipment, controls, and develop energy calculations for straightforward to moderately complex projects.
• Edit and coordinate specifications for small to medium-sized projects.

• Design DX refrigeration systems using traditional refrigerants.
• Contribute knowledge of transcritical CO₂ systems (experience with 2‑stage, cascade, or recirculated ammonia systems is a plus).
• Apply national standards (IMC, IPC, ASHRAE) and energy codes to refrigeration system design with minimal oversight.
• Utilize tools such as Heatcraft Box Load Calculator and Sporlan Virtual Engineer.
• Integrate standard commercial refrigeration control systems into your designs.

• Partner with architects and multidisciplinary engineering teams to develop coordinated construction documents.
• Participate in construction administration and support field coordination as needed.
• Perform quality control reviews on your own work and others’ before final review by the Engineer of Record.
• Maintain direct client contact and support basic project management responsibilities, including budget coordination.
• Travel occasionally to project sites as required.

• Engineer has the ability to lead a small client/client team, small projects, or portions of a large project utilizing their experience and education in refrigeration systems, controls, and knowledge of national standards that pertain to refrigeration; as well as solve medium to difficult design challenges that arise on a project.
• Engineer should have a basic understanding of energy codes and how to apply them to refrigeration systems design with minimal oversight, as well as a basic understanding of their impact on a building’s design.
• Engineer can work in an independent manner on several project and/or client types with minimal supervision from a more Senior Engineer or Designer.
• Engineer should have a good working knowledge of DX refrigeration system utilizing traditional refrigerants and a basic knowledge of transcritical CO₂ systems. Additional systems that may be helpful are 2‑stage systems, cascade systems, and recirculated ammonia systems.
• Engineer should have a basic knowledge of standard control systems used in commercial refrigeration.
• Engineer will work with Engineer and/or Design Lead to communicate with client, deliver completed construction documents, and assist in construction administration as required for most project types.
• Engineer should be able to apply their knowledge gained through experience and knowledge of recognized national standards to simple projects, with minim…

• Engineer should be proficient in AutoCAD and or Revit. The engineer should be able to train new employees on company standards, drafting techniques, and answer most technical design questions on simple projects for refrigeration design, as well as possess a basic understanding of national standards…
