Design and Prototype Engineer – Flow in Electrochemical Systems

Calion is a U.S. based energy technology startup that is developing and commercializing recently invented ionocaloric refrigeration ( and heat pumping technologies at Department of Energy’s Lawrence Berkeley National Laboratory to enable non-hazardous and zero-global-warming potential cooling and heating.

Cooling and heating account for more than 50% of energy use worldwide and is rising significantly . There is a significant need to develop high efficiency heat pumps/refrigeration to increase the energy efficiency. Furthermore hydroflorocarbons (HFCs) used in commercial technologies are potent greenhouse gases. They are on track to contribute as much as 25% of the total global warming budget. Combined with the global warming associated with energy needs, cooling and heating can contribute more than 50% to the global warming budget. Newly invented Ionocaloric refrigeration is a disruptive technology which uses electrochemical fields and ions to achieve heat pumping/cooling/refrigeration with zero global warming potential.

We need talented, hardworking individuals who share our goal of tackling this refrigerant problem so that we can cool the planet down, one-less-refrigerant-at-a-time.

Role Description:

Calion is seeking a hands-on prototype engineer to design, engineer, and build a robust flow module for our electrochemical system. The individual will work directly with the Co-founder and CEO to engineer the flow architecture and flow path, along with the sensors, controls, and supporting hardware to create a robust, compact, and efficient flow module to support our electrochemical separation process for highly efficient ionocaloric cooling.

What You’ll do:

  • Design overall flow module architecture
  • Design and execute the fabrication / assembly processes
  • Integrate sensors, controls, and supporting hardware to test and collect data on flow module performance
  • Rapid prototyping and iteration of design and extensive experimental testing and data collection


  • Bachelor's or Master's degree in Mechanical Engineering, Chemical Engineering, or related field.
  • Strong background in mechanical design and rapid prototyping.
  • Proficiency in CAD software and basic machining.
  • Familiarity with experimental design, data acquisition systems, control automation, and sensor integration.
  • Ability to take an idea to fruition quickly and independently
  • Motivation to change the world and contribute towards climate tech by developing game changing technologies


  • Experience in electrochemical and/or desalination-adjacent flow systems (thin gap)
  • Experience in sourcing components and overseeing fabrication processes.
  • Proficiency in programming
  • Excellent problem-solving skills and ability to work in a collaborative team environment.
  • Strong communication skills to present findings, collaborate effectively, and document results.
  • Hands-on laboratory experience with hazardous chemicals
