  • Perform load calculations - cooling, heating, moisture, and ventilation - for temporary climate solutions across construction sites, industrial and manufacturing facilities, food production plants, automotive and battery plants, aerospace facilities, data centers, commercial buildings, and labs
  • Perform psychrometric chart analyses and study weather to inform design decisions
  • Design temporary systems from Polygon's equipment fleet
  • Develop project layouts, equipment schedules, and sequences of operation tailored to each client's environment and process needs
  • Support the estimating process: take-offs, equipment selection, scope development, and pricing inputs for bids and proposals
  • Prepare and present engineered solutions to clients, general contractors, and internal sales teams
  • Translate technical decisions into clear, client-friendly language
  • Serve as the engineering resource for the field technician team during equipment deployment, startup, commissioning, and troubleshooting
  • Travel to project sites on short notice when needed - for emergency response, project kickoffs, complex deployments, or field issues that require engineering oversight
  • Translate field observations into improvements to design and project execution
  • Develop and maintain Standard Operating Procedures (SOPs) for specific systems, applications, and key clients
  • Create technical documentation, including system narratives, commissioning checklists, monitoring plans, and project closeout packages
  • Build out engineering templates and reference materials to improve consistency and efficiency across the team

Job Qualifications:
  • Bachelor's degree in Mechanical Engineering or a related field
  • Solid understanding of thermodynamics, heat transfer, and HVAC fundamentals
  • Comfortable with psychrometric calculations
  • Strong written and verbal communication skills, with the ability to explain technical concepts to engineers, salespeople, technicians, and clients
  • MS Office proficiency across the board, with Excel as a particular strength
  • Demonstrated CAD experience
  • Willingness to travel on short notice, including occasional nights and weekends for emergency response
  • Valid US driver's license and the ability to work on construction and industrial job sites

Preferred Training Requirements and Competencies:
  • EIT certification
  • 1-3 years of experience in HVAC, mechanical contracting, temporary climate solutions, dehumidification, or a related field
  • Exposure to construction sites, manufacturing facilities, food production, automotive or battery plants, aerospace, data centers, or controlled environments such as labs, cleanrooms, and pharmaceutical facilities
  • Familiarity with building codes, OSHA site safety, and standard PPE requirements
  • Experience supporting estimating, sales, or field service teams

Demonstration of the Polygon Values:
  • Integrity
  • Excellence
  • Empathy
