    Job description

    Weld Engineer (Contract) | Bellevue, WA (On-site)

    System One is seeking a highly motivated Weld Engineer to support a Materials Development & Qualification team advancing next-generation materials and components for sodium-cooled fast reactors. This is a hands-on, high-impact role where your weld engineering and metallurgy expertise will influence how advanced components are designed, tested, qualified, and transitioned into supplier-ready manufacturing processes.

    Location: Bellevue, WA (On-site) Type: Contract | 40 hrs/week Pay Rate: $63–$80/hr (W2)

    Why this role?

    • Contribute to advanced energy technology with direct design, qualification, and long-term deployment impact.
    • Own weld development from laboratory testing through manufacturing process definition with external suppliers.
    • Collaborate cross-functionally with engineering teams and supplier partners to mature critical components.

    What you’ll do

    • Partner with project teams to provide guidance on welding configuration, joint geometry, and method selection for development programs.
    • Develop weld designs, specifications, and processes supporting design and licensing needs.
    • Shape and inform materials test programs to validate weld/material performance models and ensure program objectives are met.
    • Analyze and interpret test data (e.g., metallography, NDE results, mechanical testing, ductility) and create technical reports documenting results.
    • Support procurement of engineered components by leading technical development with suppliers to increase technology readiness for key items.

    What we’re looking for

    Required / strongly preferred experience

    • B.S. + 3 years relevant experience (or M.S. + 2 years, or equivalent).
    • Degree in Materials Science/Engineering, Welding Engineering, Mechanical Engineering, or related technical discipline preferred.
    • Experience with weld engineering for new design (not just production support).
    • Ability to evaluate weld methods, joint geometries, and property impacts for piping, pressure vessels, and equipment.
    • Strong metallurgy foundation including welding/heat treatment of:
      • Ferrous alloys (e.g., austenitic and ferritic-martensitic steels)
      • Nonferrous alloys (e.g., nickel-base alloys)

    Nice to have

    • Working knowledge of ASME NQA-1 and ASME Section IX
    • Experience qualifying welds for highly regulated applications
    • Understanding of weld design/parameter impacts on creep, fatigue, creep-fatigue, SCC, and fracture in high-temperature systems

    Soft skills

    • Independent problem-solver with strong communication, integrity, and a collaborative working style.
    System One, and its subsidiaries including Joulé and Mountain Ltd., are leaders in delivering outsourced services and workforce solutions across North America. We help clients get work done more efficiently and economically, without compromising quality. System One not only serves as a valued partner for our clients, but we offer eligible employees health and welfare benefits coverage options including medical, dental, vision, spending accounts, life insurance, voluntary plans, as well as participation in a 401(k) plan.
