SummaryWe are seeking a
Lead Mechanical Engineer to play a key role in delivering complex projects across municipal and industrial markets focusing on the design of HVAC, plumbing, and fire protection systems for water and wastewater infrastructure, treatment facilities, pumping stations, and process buildings.
In this role, you will take
ownership of mechanical design efforts from concept through construction, working directly with clients and multidisciplinary teams to deliver high-performing, resilient infrastructure. Unlike larger, highly segmented organizations, you will have the opportunity to
influence design decisions, interface directly with clients, and see the full lifecycle of your projects.
Our projects span water and wastewater treatment, conveyance, and industrial facilities-including partnerships with municipalities and within the food and beverage sector-offering both technical variety and real-world impact on community infrastructure.
What You'll Do- Lead the design of HVAC, plumbing, and fire protection systems for water and wastewater treatment facilities
- Serve as a technical authority on mechanical systems in challenging environments (explosive, corrosive, high-moisture, odor-controlled spaces, hazardous)
- Drive design from planning and concept development through final design and construction support
- Collaborate closely with process, civil, structural, and electrical engineers to deliver integrated facility designs
- Provide direct client interaction, contributing to long-term partnerships and project success
- Perform and oversee QA/QC of mechanical designs and mentor junior staff
- Make key decisions on system layouts, equipment selection, and design standards
- Support construction activities, including RFIs, submittals, and field coordination
- Contribute to proposals and help shape upcoming project opportunities
What Sets This Role Apart- End-to-end project involvement - not siloed design work
- High visibility and ownership with both internal teams and clients
- Opportunity to work on complex treatment facilities and industrial projects, not just standard building systems
- A collaborative environment where technical input is valued and acted on
- Clear path to expanded leadership, including project management and technical specialization
Qualifications- Bachelor's or Master's degree in Mechanical Engineering
- Professional Engineer (PE) license (or ability to obtain within 6 months)
- 10+ years of experience in HVAC, plumbing, and/or fire protection design
- Experience with water/wastewater or industrial/process facilities strongly preferred
- Proficiency in AutoCAD, Revit, and related design tools are nice, but not required
- Strong communication and technical writing skills
- Ability to lead design efforts while balancing multiple priorities
- Proficiency with engineering and office software (Bluebeam, Excel, etc.)
- Valid driver's license and ability to travel as needed
