PREFERRED QUALIFICATIONS

• Experience with Thermal Energy Storage systems
• Familiarity with data center cooling architectures (air-side, water-side economization, etc.)
• Experience with industrial refrigeration or low-temperature glycol systems
• Knowledge of ASHRAE, ASME (including B31.3), IPC, NEC, and U.S. building codes
• Experience with hydraulic and pipe stress analysis software (e.g., Pipe-Flo, AutoPIPE) and energy/load modeling tools (e.g., Trace, HAP)
• Experience using Python, VBA, Dynamo, or AI tools to automate engineering workflows
• Experience developing RFP/proposal content and technical narratives
• Experience in retrofit or operational facility environments
• Startup or fast-growth company experience is a plus
• Military veterans encouraged to apply — leadership and field-operations experience translate well to this role
