About the Opportunity

Join a fast-growing clean-energy technology company developing advanced thermal energy storage solutions for commercial, industrial, and mission-critical facilities. This role will focus on integrating high-impact chilled-water and cooling-plant systems that help improve data center capacity, energy efficiency, resiliency, and grid stability.

We are seeking a Senior Mechanical Systems Engineer with strong HVAC, hydronic, and chilled-water expertise to lead mechanical integration projects from design through commissioning across the United States.

What You’ll Do

-   Lead the mechanical design and integration of thermal energy storage and chilled-water systems.
-   Develop and review P&IDs, hydronic piping layouts, equipment arrangements, valve schedules, and controls integration interfaces.
-   Perform hydraulic and pipe-stress analyses and support code-compliant engineering documentation.
-   Integrate systems with chillers, cooling towers, heat exchangers, pumps, and BAS/BMS platforms.
-   Collaborate with data center operators, MEP firms, contractors, design engineers, controls integrators, and commissioning teams.
-   Support site surveys, startup, commissioning, and functional testing activities.
-   Provide technical input for presales efforts, proposals, and RFP responses.
-   Create or apply automation tools, such as Python or Excel/VBA, to improve engineering analyses and documentation.
-   Partner with global R&D and product teams to refine system designs and deployment methods.
-   Mentor junior engineers as the engineering team expands.

What We’re Looking For

-   Bachelor’s degree in Mechanical Engineering; PE license preferred.
-   5+ years of experience in HVAC, chilled-water systems, or energy infrastructure.
-   Strong knowledge of hydronic systems, thermodynamics, cooling plants, and BAS/BMS integration.
-   Experience coordinating work across mechanical, controls, and electrical disciplines.
-   Proficiency with AutoCAD, Revit, Plant 3D, or similar design tools.
-   Familiarity with commissioning, startup, and field-execution processes.
-   Ability to travel domestically up to 20% of the time.

Preferred Qualifications

-   Experience in data centers or other mission-critical facilities.
-   Exposure to thermal energy storage systems.
-   Familiarity with data-center cooling architectures, including air-side and water-side economization.
-   Experience with industrial refrigeration or low-temperature glycol systems.
-   Knowledge of ASHRAE, ASME B31.3, IPC, NEC, and applicable U.S. building codes.
-   Experience with hydraulic or pipe-stress analysis software, such as Pipe-Flo or AutoPIPE.
-   Familiarity with energy/load modeling tools, including TRACE or HAP.
-   Experience using Python, VBA, Dynamo, or AI tools to automate engineering workflows.
-   Experience preparing technical narratives, proposals, or RFP responses.
-   Background in retrofit projects, operational facilities, or fast-growth environments.

## Benefits

-   Work on advanced clean-energy infrastructure supporting the fast-growing data center market.
-   Combine hands-on field execution with sophisticated engineering design.
-   Contribute to high-visibility, mission-critical projects with meaningful environmental impact.
