Antares

Overview

Antares is on a mission to make clean energy abundant from Earth to the Asteroid Belt by developing mass-producible, inherently safe microreactors. As a Welding Engineer II, you will support the development and production of welded hardware for reactor systems, ensuring quality and compliance in a high-stakes environment.

Responsibilities

• Develop, qualify, and maintain welding procedures, including WPS, PQR, and welder performance qualifications.
• Select appropriate welding processes, filler metals, joint designs, shielding methods, and process parameters based on material requirements.
• Provide design-for-welding guidance related to joint accessibility, distortion, residual stress, inspection, and manufacturability.
• Support welded hardware from prototype development through production, inspection, testing, and final acceptance.
• Work directly with welders, technicians, and suppliers to establish high-quality fabrication processes.
• Create manufacturing work instructions, process controls, weld maps, inspection criteria, and technical specifications.
• Develop and execute weld qualification plans, including destructive and nondestructive testing.
• Review weld documentation, inspection results, material certifications, and supplier records for compliance.
• Lead root-cause investigations for weld defects and fabrication nonconformances.
• Develop repair and rework procedures and provide technical disposition of welding-related nonconformances.
• Interface with design, materials, analysis, manufacturing, quality, and test engineers to ensure compliance.
• Support the selection and qualification of welding suppliers and outside fabrication partners.
• Promote a culture of safety, quality, documentation, and continuous process improvement.

Requirements

• Bachelor’s degree in Welding Engineering, Materials Science and Engineering, Mechanical Engineering, or a related field.
• 2+ years of professional experience in welding engineering or welded hardware manufacturing.
• Working knowledge of common fusion welding processes such as GTAW, GMAW, PAW, laser welding, or electron beam welding.
• Experience developing or supporting welding procedures and welder qualifications.
• Understanding of welding metallurgy, heat-affected zones, and common weld defects.
• Experience interpreting engineering drawings, weld symbols, and inspection requirements.
• Familiarity with destructive testing and nondestructive examination methods.
• Ability to work hands-on with production personnel and resolve manufacturing challenges.

Additional Information

• Ability to work long hours and weekends as necessary to support critical milestones.
• The Antares HQ is located in Torrance, CA, featuring large open spaces for collaboration and easy access to major freeways.
