Cushing Terrell is seeking an experienced Plumbing Mechanical Engineer to join our growing consulting team in Billings, Montana. This is a senior-level role within a multidisciplinary architecture and engineering firm, focused on the design and delivery of plumbing and HVAC systems for complex built environment projects.
If you are a consulting engineer with deep expertise in plumbing systems design — domestic water, waste, vent, and mechanical HVAC and you want to design meaningful built environment projects, we want to hear from you.
The expected salary range for this position is $90,000 to $115,000 annually.
-
Bachelor's degree or higher in Mechanical Engineering or a closely related field
-
Minimum 7 years of experience in consulting plumbing and HVAC engineering within the built environment
-
Licensed Professional Engineer (PE) in Montana, or the ability to obtain licensure — strongly preferred
-
Proven ability to design complex plumbing systems including domestic hot and cold water, sanitary waste, and vent systems to a high standard of quality
-
Proficiency in HVAC systems design including VAV, DOAS, VRF, data room cooling, packaged rooftop, chilled water cooling, and hydronic heating systems
-
Advanced knowledge of heating and cooling load calculations, ventilation calculations, hydronic pipe sizing, pump selection, duct sizing, and fan selection
-
Strong command of mechanical building codes and their application in commercial and institutional built environment projects
-
Advanced understanding of digital temperature control systems, control strategies, sequences of operation, and control drawings
-
Proficiency in writing mechanical specifications for consulting engineering projects
-
Ability to lead and collaborate with a team of engineers and drafters to produce high-quality construction documents
-
Excellent written and verbal communication skills with the ability to deliver a high level of client service
If you meet most of the qualifications above and are confident you can do this work, we encourage you to apply. Plumbing and mechanical engineering experience in a built environment consulting or A/E firm setting is the most important factor — not checking every box.
-
Develop plumbing and mechanical HVAC design concepts independently or in collaboration with a multidisciplinary A/E team
-
Consult directly with clients to define project needs, goals, and budget parameters, and translate those into engineered systems solutions
-
Conduct site assessments and building evaluations to produce engineering reports and recommendations for improvement of existing plumbing and mechanical systems
-
Identify energy conservation opportunities, quantify potential savings, and estimate construction costs for recommended measures
-
Act as Engineer in Responsible Charge — making technical decisions, reviewing, stamping, and signing construction documents for plumbing and mechanical scopes
-
Provide quality control reviews of plumbing and mechanical designs across the team and deliver constructive, actionable feedback
-
Maintain proficiency in relevant software including Microsoft Office 365, Bluebeam, and HVAC/plumbing engineering design tools
-
