Job description

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.
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.
Join Us in Advancing Modern Welding Systems
We are redefining welding by integrating advanced joining technologies, automation, and process control into a unified manufacturing system. From precision orbital tube welds to high-throughput robotic cells, we treat welding as a critical, data-driven discipline that directly impacts structural integrity, performance, and scalability.
We are solving complex challenges across arc welding, laser systems, resistance welding, and automated joining platforms. This requires engineers with deep process expertise who can operate across both manual and highly automated environments.
This is a general opportunity to engage welding engineers with specialized experience across key welding processes and technologies.
Core Specialty Areas
  • Arc Welding (Manual & Semi-Automated): Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW - circumferential and linear/seam welding)
  • Advanced / Precision Welding: Orbital Tube Welding (OTW), Plasma Arc Welding (PAW - robotic cell)
  • Laser Welding Systems: Laser weld cells, manual handheld laser welding
  • Resistance Welding: Resistance Spot Welding (RSW), stud welding
  • High-Deposition / Automated Welding: Submerged Arc Welding (SAW - robotic cell)

What You'll Do
  • Apply specialized welding process knowledge to develop, qualify, and optimize welding operations
  • Establish and control welding parameters (heat input, travel speed, shielding gas, etc.) to ensure weld integrity and repeatability
  • Partner with manufacturing, quality, and automation teams to deploy stable, scalable welding systems
  • Develop WPS/PQR documentation and ensure compliance with applicable codes and standards
  • Lead root cause analysis and continuous improvement efforts related to weld defects, distortion, and throughput

What We're Looking For
  • Degree in Welding Engineering, Materials Engineering, Mechanical Engineering, or equivalent hands-on experience
  • Demonstrated expertise in at least one welding process or system listed above
  • Strong understanding of weld metallurgy, heat-affected zones, and defect mechanisms (porosity, cracking, lack of fusion, etc.)
  • Ability to read and interpret weld symbols, drawings, and technical specifications
  • Experience working in production environments with a focus on process stability and quality

What Will Set You Apart
  • Experience across multiple welding modalities (e.g., arc + laser + resistance)
  • Background in automated or robotic welding systems and cell integration
  • Familiarity with NDT methods (UT, RT, PT, VT) and weld inspection standards
  • Experience in aerospace, pressure vessels, energy systems, or other high-spec applications

Benefits for Full-time Employees
  • Medical, dental, vision, and life insurance plans for employees
  • 401k
  • Relocation support may be provided for certain situations, based on business need.
  • Flexible vacation policy

ITAR Requirements
To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Hadrian Is An Equal Opportunity Employer
It is the Company's policy to provide equal employment opportunity for all applicants and employees. The Company does not unlawfully discriminate on the basis of race inclusive of traits historically associated with race (including, but not limited to, hair texture and protective hairstyles, such as braids, locks and twists), color, religion, sex (including pregnancy, childbirth, or related medical conditions), gender identity, gender expression, transgender status, national origin (including, in California, possession of a drivers license), ancestry, citizenship, age, physical or mental disability, height or weight, medical condition, family care status, military or veteran status, marital status, domestic partner status, sexual orientation, genetic information, exercise of reproductive rights, any other basis protected by local, state, or federal laws, or any combination of the above characteristics.
