Helix Earth

 Mechanical Engineer
 
 
 
 
 Helix Earth
 
 (Houston, TX 77004) is a clean tech startup where we're fixing how the world handles humidity in buildings. Air conditioning is on track to account for 8% of global CO2 emissions by 2050, and most of that energy is simply wasted fighting humidity. We spun out of Rice University and NASA in 2022 to solve that. By adapting technology our co-founder invented for NASA space exploration, we aim drastically cut air conditioning energy use and improve indoor air quality.
 
 
 
 
 
 
 Helix Earth
 
 has won numerous awards including the
 
 Smart Cities pitch contest at SXSW
 
 and our Co-Founder Dr. Rawand Rasheed was named to
 
 Forbes 30 under 30
 
 for Energy and Green Tech.
 
 
 
 
 
 Helix Earth is seeking a
 
 Mechanical Engineer
 
 , who will report directly to the Engineering Manager and Lead Engineer. The position will be onsite and located at our Houston, TX offices.
