Senior Turbomachinery Engineer

Senior Turbomachinery Engineer  

Radiant is seeking a highly motivated senior turbomachinery engineer to develop turbomachinery in support of a simply recuperated, supercritical CO2 (sCO2) Brayton engine. This candidate will have the opportunity to work in a fast-paced startup environment to develop power generation hardware to enable portable nuclear micro-reactors.  This role consists of developing turbomachinery hardware at the heart of the sCO2 heat engine while considering long term production requirements related to hardware performance, reliability, mass, and cost. The ideal candidate is experienced in building early concept hardware components through production and are excited about our vision to power remote communities with clean, portable and reliable nuclear energy. 

Responsibilities and Duties:  

•  Translate heat engine performance requirements and trade conceptual designs for sCO2 machinery on first article and production-grade versions of Kaleidos. 
•  Work with the responsible engineers of adjacent systems to globally optimize Kaleidos hardware and operations for levelized cost of electricity (LCOE). 
•  Own and maintain performance modeling of the heat engine. 
•  Oversee the build and testing of first article heat engine hardware. 

Required Qualifications and Skills: 

•  4+ years industry experience + BS from accredited institution.
•  Knowledge of turbomachinery design and build principles. 
•  Experience translating broad machinery requirements (power, speed, bearing leakage) into a conceptual design, including wheel and shaft design, as well as bearing and alternator selection. 
•  Demonstrated experience in owning end-to-end hardware development cycle, from concept, part design, manufacturing, through build and testing. 

Desired Qualifications and Skills:  

• Experience with the supercritical CO2 Brayton cycle. 
• Experience optimizing power generation cycles via industry or custom software. 
• Familiarity with AC power generation and power electronics.
