About the Role
The Senior Mechanical Project Engineer helps clients identify, design, and implement utility and infrastructure improvements. This role solves the challenge of turning complex facility needs into practical projects that improve performance, reliability, and cost efficiency. The position leads technical assessments, feasibility analysis, project scoping, and engineering design to support informed investment decisions. This role is critical to delivering accurate project recommendations, strong technical solutions, and well-executed engineering support from concept through implementation.
Responsibilities
- Complete 95% of assigned site surveys, feasibility studies, and investment-grade cost estimates by the committed deadline, with less than 5% requiring material rework due to engineering errors or omissions.
- Develop and deliver technical scopes, project economics, and engineering recommendations that contribute to at least $5M annually in qualified project opportunities approved for proposal or implementation.
- Demonstrate a consistently positive attitude, strong collaboration, and reliable responsiveness with clients, internal teams, and project partners, as evidenced by constructive stakeholder feedback and dependable follow-through on commitments.
- Conduct site surveys and collect technical, operational, utility, and cost data to establish project baselines and identify client needs.
- Analyze facility infrastructure, utility systems, and operating conditions to identify energy, water, and operational improvement opportunities.
- Perform feasibility studies and technical evaluations for utility modernization and energy efficiency solutions.
- Develop project scopes, engineering assumptions, savings calculations, and investment-grade cost estimates.
- Prepare technical recommendations, project economics, and supporting documentation for client proposals and decision-making.
- Lead design engineering activities for approved projects, ensuring technical quality and alignment with project objectives.
- Coordinate internal and external engineering resources to deliver design work on schedule and within scope.
- Manage engineering support for project implementation, including design-build coordination, technical reviews, and integration of applicable incentives or funding opportunities.
Requirements
- Bachelor’s degree in engineering or a related technical field.
- 5-10 years of experience in development, design, or delivery of utility system modernization, energy efficiency, or related infrastructure projects.
- Experience supporting industrial and/or commercial projects.
- Technical experience with utility, HVAC, mechanical, or related infrastructure systems.
- Ability to independently manage engineering work and coordinate with clients, internal teams, and external partners.
