Welding Engineer, Special Projects

Hadrian - Manufacturing the Future

Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.

Valued at $1.6B, we’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.

Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.

We are seeking a Welding Engineer to support the development of Hadrian’s next-generation automated factory systems for mission-critical aerospace and defense components. You will work alongside a highly driven team of design, automation, and manufacturing engineers to bring welded assemblies from concept through full-rate production.

This is a hands‑on, factory‑integrated role requiring strong technical depth in materials and welding processes, as well as comfort operating in high pace manufacturing environments.

• Develop, qualify, and optimize welding processes including, but not limited to laser beam welding, gas tungsten arc welding (GTAW), orbital tube welding, resistance welding, gas metal arc welding (GMAW), friction stir welding, and plasma arc welding

• Work with welding of high strength steel, stainless steel, aluminum, titanium, and other high-performance alloys

• Collaborate closely with design, tooling, automation, and manufacturing engineers to implement new parts and welding technologies into production

• Partner with NDE personnel to evaluate weld quality on development and production hardware, and support the implementation of advanced inspection techniques

• Support production scale‑up by creating detailed welding work instructions, defining equipment maintenance plans, and authoring Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR)

• Ensure compliance with applicable aerospace, defense, and maritime welding standards

• Bachelor’s degree in Welding Engineering, Materials Science, Mechanical Engineering, or a related field (equivalent experience considered)

• 2–8+ years of experience in welding engineering or weld process development

• Fundamental understanding of:

• Laser beam welding, gas tungsten arc welding, orbital tube welding, resistance welding, gas metal arc welding, friction stir welding, and plasma arc welding

• High‑strength steel, stainless steel, nickel‑based alloys, titanium, and aluminum alloys

• Self‑motivated with strong attention to detail

• Demonstrated ability to manage multiple priorities and clearly communicate status and results across a broad range of internal and external stakeholders

• Experience in aerospace, defense, shipbuilding, or offshore manufacturing

• Familiarity with standards such as:

• AWS (e.g., D1.1, D1.2, D17.1), ASME Section IX, MIL‑STD welding requirements, ABS, NAVSEA, DNV, or other maritime classification standards

• Experience with robotic or automated welding systems

• Exposure to NDT processes and inspection program development

• Experience qualifying and managing external weld suppliers

• Background in high‑mix, low‑volume or advanced manufacturing environments

For this role, the target salary range is $125,000‑$175,000 (actual range may vary based on experience). This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future.

An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications,…
