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 Additive Manufacturing

We are building next-generation additive manufacturing (AM) systems by integrating materials science, process physics, and digital workflows into a unified production environment. From feedstock development and build preparation through printing, post-processing, and validation, we treat AM as a fully coupled thermal, mechanical, and materials system.

We are solving complex challenges in distortion control, material properties, multi-material integration, and production scalability. This requires engineers with deep expertise across AM processes, materials, and qualification frameworks.

This is a general opportunity to engage additive manufacturing engineers with specialized experience across key process areas.

Core Specialty Areas

• AM Materials & Feedstock: Metals (Ti-6Al-4V, Inconel 625/718, Scalmalloy, CuNi30, CP1), polymers, photopolymers, multi-material systems, feedstock development and qualification
• Process Development & Build Strategy: AM build preparation, laser path generation, parameter development, distortion compensation, process robustness
• Design for Additive Manufacturing (DfAM): Topology optimization, support strategies, tooling design
• Process Monitoring & Control: In-situ monitoring, closed-loop control systems, defect detection
• Post-Processing & Finishing: Heat treatment, machining, surface finishing, post-process development
• Testing & Material Characterization: Tensile and fatigue testing, chemical analysis, microstructural (micrographic) analysis, powder characterization
• Inspection & Validation: 3D scanning, CT scanning, advanced NDE and defect characterization
• Data & Material Systems: Material property development, database creation, qualification frameworks

What You'll Do

• Develop, qualify, and scale additive manufacturing processes for performance, repeatability, and production readiness
• Control critical variables (energy input, scan strategy, thermal gradients, material behavior) to ensure part integrity
• Partner with design, materials, and manufacturing teams to implement robust AM production systems
• Lead root cause analysis for defects such as porosity, cracking, distortion, and anisotropic behavior
• Build and maintain process standards, material databases, and qualification documentation

What We're Looking For

• Degree in Materials Science, Mechanical Engineering, Aerospace Engineering, or equivalent hands-on AM experience
• Demonstrated expertise in additive manufacturing processes, materials, or qualification
• Strong understanding of thermal processes, microstructure evolution, and material properties in AM
• Ability to interpret complex geometries, drawings, and performance requirements
• Experience in production or R&D environments focused on process control and validation

What Will Set You Apart

• Experience across the full AM lifecycle (design ? build ? post-process ? inspection ? qualification)
• Deep expertise in metal AM systems (LPBF, DED) or advanced polymer AM
• Familiarity with multi-material printing and advanced process control systems
• Experience in aerospace, defense, or other high-performance 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
