Rebound Technologies

At Rebound, for the last 12 years, we have been developing a revolutionary technology that will change how we cool everything. It is based on a freeze point suppression cycle that offers a 3-in-1 solution, combining agile freezing, unprecedented humidity control and demand response capabilities. Addressing huge markets like cold chain logistics companies, data centers and frozen food processors, Rebound’s IcePoint® meets varying cooling demands while simultaneously optimizing moisture levels equating to improved system performance, increased productivity, lower demand charges and excellent return on investment. IcePoint’s thermal storage capability has already proven to be the cheapest battery on the planet, and will support decarbonization of the grid via year-round thermal storage and flexible demand.

We are looking for team members to support our fast growth. This position requires above average attention to details, concern for the exact correctness of work, and strong commitment to tasks completed on time. The person in this position is expected to take work seriously, have a strong sense of duty, and be disciplined. We are looking at a somewhat faster-than-average pace that will be the norm for this position. Detailed, specialized work is the major focus. The person in this position will be given clearly defined work, responsibilities, and reporting relationships, ongoing and thorough training opportunities to develop expertise and increase confidence. The position will provide security in a stable work environment, allowing you to plan for, focus on and complete tasks on hand.


Job functions

  • Lead thermal engineering for state-of-the-art process equipment.
  • Size thermal process equipment: pumps, compressors, heat exchangers, control valves, etc. using thermal-mechanical models
  • Model refrigeration cycles using thermal statepoint approach in both transient and steady state conditions
  • Create complex 3d CFD models of components capturing multi-phase flows and dynamic solid-liquid geometries
  • Work closely with controls engineers to design stable, high-reliability systems.
  • Perform data analysis on large thermal datasets to assess system performance and improvement pathways.
  • Write and execute complex iterative design software in native environments.

Skills you will require

  • Experience with thermal design of process equipment from the ground up: pumps, HXs, compressors, etc.
  • Understanding of the interplay between thermal design and controls design.
  • Experience in object-oriented languages writing thermal models (iterative solvers, high stiffness, multi-phase)
  • Deep or intuitive knowledge of thermo-mechanical process equipment sizing or operation.

Skills that will make you stand out

  • Thermal modeling experience in Python creating iterative solvers and complex models from scratch
  • Experience with packaged thermal design software: Aspen, Pipeflo, Simulink, etc.
  • Controls experience and PLC hardware familiarity.
  • Experience with MVR, distillation, or other brine separation techniques.
  • Experience with ice making, ice banking, or other ice storage techniques.
  • Experience with random or structured packing in the chemicals industry

This position is full time on premise at our Denver based HQ. You are also expected to travel 25% of the time.

Pay Range: $120,000.00 - $175,000.00 per year
