About the Company

Icebox Energy is building critical cooling infrastructure for the next generation of data

centers—meeting the demands of AI and high-density compute without relying on water or

synthetic refrigerants. Our platform is engineered from the outside in, using carbon dioxide as a

natural working fluid to solve thermal bottlenecks with cleaner, more scalable technology.

While our initial focus is data centers, our core technology has broader applications across

energy, industrial cooling, and heat reuse—wherever performance, efficiency, and sustainability

need to align.

We strive for success—not just in what we build, but in how we build it. We value integrity,

initiative, and thoughtful innovation.

About the Role

We are seeking a highly skilled Senior Mechanical Engineer with thermodynamics expertise to

join our team. The ideal candidate will be responsible for applying thermodynamic principles to
