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.
• Build a path toward technical leadership within a growing engineering organization.
• Receive a competitive compensation package including base salary, bonus potential, benefits, and stock options.
• Military veterans are encouraged to apply; leadership and field-operations experience are highly valued.
