Senior mechanical engineer

Oakwell is an infrastructure and resource efficiency firm for health systems and higher education institutions — a group of engineers, data scientists, financiers, sustainability and real estate experts delivering high-ROI infrastructure projects for organizations across the United States. As a Senior Mechanical Engineer, you are the owner's engineer clients rely on: the technical lead who owns decarbonization programs end-to-end, from concept to completion, with the professional autonomy and strategic influence to shape how major infrastructure initiatives get delivered. $670M+ saved across 150+ projects — and counting. That efficiency is on track to expand access to healthcare and education for 1,000,000 people. We are looking for partners to help us get there.

This is a remote opportunity with a preference that candidates be located in the Northeast

What you'll own: Lead 10-year sustainability and decarbonization plans for health-system clients — from benchmarking through funded, verified ECMs — cutting energy, carbon, and operating cost. Own retro-commissioning and energy modeling across central plant, air handling, terminal equipment, and energy management systems, using our custom modeling software. Develop investment-grade ECMs and sustainable MEP standards that clients adopt as their own. Serve as the client- and construction-facing lead through implementation and commissioning, and present findings and recommendations directly to owners. Secure efficiency incentives through utility technical-assistance studies. Shape the AI/ML tooling that scales our analysis, and mentor the engineers coming up behind you.

What you'll bring: Must have: Bachelor's or Master's in Mechanical Engineering; 10–15 years of experience; Professional Engineering license; deep energy-modeling and retro-commissioning experience; a track record developing ROI-driven ECMs; availability to travel as needed (~20%). Nice to have: Healthcare or other mission-critical facility experience; investment-grade audits; automation or tool-building; proficiency in Revit and eQUEST; ASHRAE/IBPSA involvement. If you meet most of these and are excited by the mission, we want to hear from you.

What makes you a great Oakwell teammate? You take ownership and demonstrate agency to drive projects forward. Working collaboratively in a team is second nature to you. You thrive in ambiguity and changing priorities while delivering with consistency.
