Résumé du poste

Aalo Atomics, based in Austin, TX, is seeking a Mechanical Engineer to lead the end-to-end steam-system design for its modular reactors. The role covers heat balance, piping layouts, equipment specs, and integration with the turbine island, with emphasis on safety, reliability, and code compliance.

The ideal candidate has 4+ years of hands-on steam systems experience across utility, industrial, marine, or nuclear contexts, along with strong knowledge of ASME codes and thermodynamics.

Qualifications

• 10+ years of experience preferred; minimum of 4 years with relevant hands-on experience required.
• B.S. in Mechanical Engineering or greater.
• Experience designing steam systems for utility, industrial, marine, or nuclear steam turbine generators, including sizing, layout, and specification of high-energy steam and feedwater piping and components.
• Experience with applicable codes and standards: ASME B31.1/B31.3, ASME BPVC Sections I, II, V, VIII, IX, ASME PTC 6 and PTC 46, IEEE, ANSI, NEMA, and TEMA standards.
• Solid grounding in steam-cycle thermodynamics, two-phase flow, water hammer, NPSH and cavitation, steam purity and cycle chemistry (EPRI guidelines), and erosion/corrosion (FAC) considerations.
• Demonstrated ability to produce engineering deliverables (calculations, specifications, design basis documents) that withstand independent technical review and regulatory audit.

Responsabilités

• Own steam-cycle mechanical design from heat balance through detailed engineering, including system sizing, piping layouts, equipment specification, and integration with the turbine island.
• 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.
• Develop and review P&IDs, PFDs, equipment datasheets, isometrics, and design basis documents; 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.
• 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.
• 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.
