About the role

  • The ideal candidate combines sound welding fundamentals with a hands-on, practical approach to manufacturing.
  • Work directly with welders, technicians, and suppliers to establish repeatable, high-quality fabrication processes.
  • Promote a strong culture of safety, quality, documentation, and continuous process improvement.

Responsibilities

  • Develop, qualify, and maintain welding procedures, including Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and welder performance qualifications.
  • Provide design-for-welding guidance, including recommendations related to joint accessibility, distortion, residual stress, inspection, and manufacturability.
  • Support welded hardware from prototype development through production, inspection, testing, and final acceptance.
  • Create manufacturing work instructions, process controls, weld maps, inspection criteria, and technical specifications.
  • Develop and execute weld qualification plans, including destructive and nondestructive testing.
  • Lead root-cause investigations for weld defects, distortion, cracking, leakage, and other fabrication nonconformances.
  • Develop repair and rework procedures and provide technical disposition of welding-related nonconformances.
  • Support the selection, qualification, and technical oversight of welding suppliers and outside fabrication partners.
  • Select appropriate welding processes, filler metals, joint designs, shielding methods, and process parameters based on material and component requirements.
  • Interface with design, materials, analysis, manufacturing, quality, and test engineers to ensure welded assemblies satisfy structural, thermal, pressure, and lifetime requirements.

Requirements

  • Bachelor's degree in Welding Engineering, Materials Science and Engineering, Mechanical Engineering, or a related technical field.
  • 2+ years of professional experience in welding engineering, joining processes, or welded hardware manufacturing.
  • Working knowledge of common fusion welding processes, such as GTAW, GMAW, PAW, laser welding, or electron beam welding.
  • Experience interpreting engineering drawings, weld symbols, material specifications, and inspection requirements.
  • Familiarity with destructive testing and nondestructive examination methods used to evaluate weld quality.
  • Ability to work hands-on with production personnel and independently resolve manufacturing challenges.
  • 3+ years of welding engineering experience in aerospace, nuclear, pressure vessel, power generation, defense, or another highly regulated industry.
  • Knowledge of applicable welding and fabrication codes, including ASME Section IX, ASME Boiler and Pressure Vessel Code, AWS D17.1, AWS D1.1, or equivalent standards.
  • Familiarity with advanced welding processes, including automated orbital GTAW, laser beam welding, electron beam welding, resistance welding, or additive repair.

Nice to have

  • Preferred Skills and Experience:

Skills

  • Experience welding stainless steels, nickel-based superalloys, refractory metals, or dissimilar-metal combinations.
  • Experience with pressure-boundary, high-temperature, vacuum, or leak-tight welded assemblies.
  • Experience with weld inspection methods such as visual, dye penetrant, radiographic, ultrasonic, leak, or metallographic examination.
  • Familiarity with post-weld heat treatment, stress relief, cleaning, passivation, and contamination control.
  • Experience conducting weld failure investigations using metallography, microscopy, hardness testing, or mechanical testing.

Company info

  • At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We're fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we're building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.
  • Formed in 2023, the Antares team hails from SpaceX, The White House, MIT, Rigetti Computing, The Air Force, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Los Alamos, Idaho, and Oak Ridge. Antares has raised over $130M in venture capital from top-tier investors and has over $13M in government funding.
  • About the Team
  • As a Welding Engineer II at Antares, you will support the development, qualification, and production of welded hardware for our reactor systems. You will own welding processes from early design and material selection through procedure development, qualification, manufacturing, inspection, and final acceptance. This role requires a strong understanding of welding metallurgy, fabrication processes, and weld quality-particularly for stainless steels, nickel-based superalloys, and other materials used in high-temperature and demanding environments. You will work closely with design, materials, manufacturing, quality, and external suppliers to ensure welded assemblies meet performance, reliability, and regulatory requirements.
