Job description

Description

Cushing Terrell is seeking an experienced Plumbing and 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.

Plumbing-Mechanical Engineer Position Salary Range*

The expected salary range for this position is $90,000 to $115,000 annually.

Plumbing-Mechanical Engineer Required Qualifications**

• 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

We encourage you to apply if you meet most of these qualifications. Plumbing and mechanical engineering experience in a built environment consulting or A/E firm setting is the most important factor — not checking every box.

Plumbing-Mechanical Engineer Position Responsibilities***

• 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
• Contribute to the growth of Cushing Terrell's integrated A/E consulting practice and the depth of expertise within our mechanical team
