The Team
As part of the Engineering organization, Power Conversion develops the technologies that efficiently transform reactor-generated heat into usable electrical power. The team focuses on maximizing system performance, reliability, and commercial viability.
The Role
Valar Atomics is seeking a turbomachinery aerodynamics engineer to join the turbomachinery team and advance power generation capability. In this role, you'll be responsible for the cycle performance modeling for cutting edge turbomachinery. You'll be working with cross-functional team members to define a high efficiency, highly producible cycle design. As an early hire in turbomachinery, you will be able to directly influence design decisions on the system architecture.
Key Responsibilities
- Develop and maintain a thermodynamic model of the power conversion system
- Aggregate, interpret and integrate the contributions of component owners into the overall cycle model
- Partner with turbomachinery, secondary flow, and heat exchanger owners to input their component performance into the system model
- Define instrumentation plans to calibrate the cycle model to tested results
- Evaluate system level trades to drive the cycle to the optimal business outcome
You Will Be Successful in This Role If
- You are excited to be a part of a complex turbomachinery product from the beginning
- You thrive in ambiguous environments without defined turbomachinery design best practices
- You want to be part of turbomachinery design beyond a singular aerodynamic, structural or manufacturing perspective
Basic Qualifications
- Bachelor's degree in Mechanical or Aerospace Engineering
- 3 years experience in analyzing thermodynamic cycles in a thermodynamic solver (NPSS, Aspen, GateCycle, Flownex, EES, etc.)
Preferred Skills and Experience
- Master's degree in Mechanical or Aerospace Engineering
- Experience with modeling closed cycles
- Test experience with turbomachinery
- Experience with supercritical C02
- Experience analyzing turbomachinery at a component design level
