Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.
Expect depth on vessel design basis, load cases, flange and nozzle design, fatigue/creep thinking, and how you document assumptions. Be ready to discuss nuclear quality culture, vendor/fab interfaces, and trade-offs between fabrication practicality and code compliance.
Strong fit if you have senior ASME vessel/tank design experience and want to apply it to advanced nuclear hardware at a Rockville-area reactor developer. Less ideal if you prefer pure plant ops or non-pressure mechanical work.
As Senior Pressure Vessels/Tanks Engineer at X-energy, you would support design, analysis, and fabrication oversight of pressure-retaining equipment for advanced reactor systems—codes, materials, nozzles, supports, and interfaces with nuclear quality and safety requirements on Xe-100–related hardware.
Prioritize ASME BPVC Section VIII (and nuclear-adjacent Section III awareness), FEA for vessels, welding/NDE familiarity, materials for high-temperature service, and clear calculation packages. No certification cost data was supplied for this listing.
