Mechanical Engineer - Steam Systems

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

• 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, and 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.

Required Qualifications

• 10+ years of experience preferred; minimum of 4 years with relevant hands-on experience required
• B.S. in Mechanical Engineering or greater
• Professional Engineer (PE) license or active progress toward licensure; PE strongly preferred at the 10+ year level.
• Demonstrated experience designing steam systems for utility, industrial, marine, or nuclear steam turbine generators, including hands-on responsibility for sizing, layout, and specification of high-energy steam and feedwater piping and components.
• Experience with applicable codes and standards:
• ASME B31.1 (Power Piping) and/or B31.3 (Process Piping)
• ASME BPVC Sections I, II, V, VIII, and IX, ASME OM (where applicable)
• ASME PTC 6 and PTC 46 for performance testing
• Relevant IEEE, ANSI, NEMA, and TEMA standards.
• Proficiency with pipe stress tools such CAESAR II or AutoPIPE, and familiarity with 3D plant modeling environments (e.g., SmartPlant, PDMS/E3D, AVEVA, Navisworks).
• 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.

Physical

• Comfortable working in a hands-on lab and factory environment
• Ability to lift up to 25 lbs and stand for extended periods
• Willingness to perform hands-on work including assembly, plumbing, wiring, and troubleshooting

Requirements

• Must be based in the United States
• Must be willing to work on-site at our headquarters in Austin, Texas
