Senior HVAC Systems Engineer

Senior HVAC Systems Engineer

Location: Carrollton, TX
Compensation: $140,000 – $180,000 base salary, commensurate with experience

Overview

We are partnering with an innovative HVAC technology company developing OEM-designed, high-efficiency heat pump and HVAC systems for residential, multi-family, and hospitality applications. This organization specializes in component-level system design, modeling, and validation, with a strong focus on energy efficiency, advanced controls, and next-generation HVAC technology.

The Role

The Senior HVAC Systems Engineer will serve as a technical leader within an HVAC R&D organization, responsible for system-level HVAC architecture, component selection, thermal modeling, and performance validation. This role is hands-on and design-focused—not MEP or field application based.

Core Responsibilities

• Perform HVAC system-level design including compressors, heat exchangers, expansion devices, and refrigerant circuits
• Conduct heat pump system modeling and simulation using tools such as ORNL HPDM, MATLAB, Modelica, or equivalent
• Optimize COP, EER, SEER, HSPF, and part-load performance
• Design and evaluate variable-speed compressor systems, EEVs, BLDC motors, and microchannel heat exchangers
• Support system validation, lab testing, and commissioning, correlating test data with simulation results
• Develop and support HVAC control strategies and control algorithms
• Apply ASHRAE, AHRI, UL, DOE, and EPA standards and compliance requirements
• Collaborate with OEM manufacturing, suppliers, ODMs, and R&D partners
• Drive technology improvements in high-efficiency heat pumps, electrification, and decarbonization

Required Experience & Technical Skills

• Bachelor’s degree in Mechanical Engineering (MS preferred)
• 5+ years of OEM HVAC systems engineering experience
• Proven background in component-level HVAC design (not MEP consulting)
• Strong knowledge of:
• • Thermodynamics, heat transfer, and fluid dynamics
  • Refrigeration cycles and refrigerants (R-410A, R-32, R-454B, CO2 a plus)
  • Heat pump system architecture and optimization
• Hands-on experience with HVAC simulation software (HPDM strongly preferred)
• Experience with controls development, control logic, and system integration
• Familiarity with R&D, prototype builds, DFMEA, validation plans, and lab testing

Preferred

• Experience with top-tier HVAC OEMs or manufacturers
• Residential or light commercial heat pump product development
• Electrification, inverter technology, and variable-capacity systems
• Exposure to DOE efficiency testing and regulatory compliance
• Proven record of new product introduction (NPI)

Why Join?

• Design next-generation HVAC and heat pump systems from the ground up
• Work in a true OEM R&D environment
• High compensation aligned with senior-level technical impact
• Direct influence on energy efficiency and sustainability outcomes
