Job description

Job Title: Senior Welding Engineer
Location: Bellevue, WA
Type: Contract
Compensation: $56.00
Contractor Work Model: Onsite – onsite
Hours: 40.0

Overview

System One is seeking a Senior Welding Engineer for a yearlong contract role to work as part of a high‑functioning team of engineers focused on materials processing, supply chain development, and supplier qualification for next‑generation materials and components for sodium‑cooled fast reactors. Must be local to the Bellevue, WA area. You will be responsible for developing the welding processes as well as developing the test programs necessary for generating necessary design information.

Responsibilities

• Develop and qualify welding techniques for nuclear reactor core internals for a sodium‑cooled fast reactor
• Conduct welding process development and qualification for ferritic‑martensitic steels and austenitic stainless steels using multiple technologies (e.g., resistance pressure welding, TIG, laser)
• Generate welding process specifications and procedures, and review engineering documentation to ensure appropriate callouts
• Lead technical development of suppliers to increase technology readiness levels of key materials and components for the core of the reactor
• Oversee weld equipment operations to generate test coupons supporting process qualification and test programs to develop performance models
• Develop destructive and nondestructive inspection criteria for weld certification
• Use fundamental materials engineering principles to develop basic models of material performance and validate them using laboratory testing
• Develop test requirements, plans, specifications, and procedures for testing
• Oversee test programs for qualification of welds, including mechanical properties, burst testing, thermal creep, creep‑fatigue, neutron irradiation, thermal aging, and sodium exposure
• Perform scientific analysis on test data and generate technical reports documenting new knowledge related to reactor design and qualification
• Interface with project teams to ensure materials development and testing efforts meet programmatic objectives across client initiatives
• Assist with supplier audits per ASME NQA‑1‑2015

Requirements

• Minimum of 6 years of related experience with a Bachelor’s degree; or 3 years of experience with a Master’s degree
• Degree in Materials Science/Engineering, Mechanical Engineering, or a related technical discipline (BA required)
• Solid understanding of metallurgy, including fabrication and thermomechanical processing of ferrous (e.g., ferritic‑martensitic steels) and nonferrous (e.g., nickel‑base) alloys
• Demonstrated skills in developing requirements specifications and defining supplier technical work scope, including development of SOWs and RFPs, and providing technical direction and oversight of supplier projects
• Experience working in stringent quality systems (e.g., NQA‑1, ISO‑9001, AS9100) preferred
• General understanding of nuclear reactor design and subsequent impacts on materials considered a plus
• Ability to work with minimum direction to solve challenging problems
• High degree of trust and integrity, ability to communicate openly, and desire to foster teamwork
• Local to the Bellevue, WA area

Benefits

The role offers health and welfare benefits coverage options including medical, dental, vision, spending accounts, life insurance, voluntary plans, and participation in a 401(k) plan.
