Our mission is to make nuclear energy globally accessible, starting with the Aalo-1, a 10 MWe reactor leveraging cutting-edge safety, modularity, and efficiency. Based in Austin, TX, we’re rapidly growing as we work to deploy the world’s first fleet of advanced microreactors. Join us and help revolutionize energy for a sustainable future.
About the role:
We are seeking a Mechanical Engineer to lead the design, analysis, and integration of steam systems supporting a steam turbine generator (STG). This role is responsible for the end-to-end mechanical design of main steam, reheat, extraction, auxiliary steam, condensate, and feedwater systems, ensuring performance, reliability, safety, and code compliance from concept through commissioning. The engineer will interface directly with the turbine OEM, balance-of-plant designers, and controls engineers.
Key Responsibilities
The successful candidate will own steam-cycle mechanical design from heat balance through detailed engineering, including system sizing, piping layouts, equipment specification, and integration with the turbine island. They will perform pipe stress and flexibility analysis (per ASME B31.1 or B31.3 as applicable), water hammer and two-phase flow evaluations, and steam purity/chemistry compatibility studies. They will develop and review P&IDs, PFDs, equipment datasheets, isometrics, and design basis documents, and will specify major components including main steam stop and control valves, isolation valves, safety/relief valves, steam traps, separators, desuperheaters, condensers, feedwater heaters, deaerators, and associated piping and supports.
They will lead the technical interface with the turbine OEM on steam admission conditions, extraction points, exhaust hood design, sealing steam, gland systems, and lube/control oil interfaces. They will participate in design reviews, vendor qualification, factory acceptance testing, construction support, commissioning, performance testing (per ASME PTC 6 and related codes), and root-cause analysis of in-service issues.
