About the role
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. The Role: Join us in shaping the future of aerospace and defense manufacturing. As an Additive Manufacturing Engineer - Applications , you will serve as a technical bridge between customer requirements and production-ready metal additive manufacturing solutions. You will work closely with customers and internal teams to evaluate part feasibility, guide Design for Additive Manufacturing (DfAM), support process development, and help scale programs from early engagement through qualification and production. This is a hands-on, customer-facing engineering role at the intersection of applications engineering, manufacturing execution, and process development. You will help solve real-world metal AM challenges, convert those solutions into repeatable manufacturing methods, and support the successful launch of high-impact aerospace and defense programs. What You’ll Do: Customer Technical Support & Requirements Capture: Support technical engagement with customers by gathering requirements, clarifying design intent, and translating program needs into actionable manufacturing plans that align customer requirements with feasible additive manufacturing solutions. Program Feasibility & Application Development: Evaluate part and program fit for metal additive manufacturing, identify technical risks, and develop new additive applications, processes, and manufacturing approaches that expand capability and support new business opportunities. DfAM & Design Reviews: Provide DfAM guidance on build orientation, support strategy, feature design, distortion risk, tolerance approach, and post-processing-aware design decisions while collaborating closely with design, analysis, quality, manufacturing, and responsible engineers. Build Planning & Build File Optimization: Develop and optimize build strategies, build files, and print plans to produce high quality parts in minimum time with maximum consistency, including parameter refinement and support for part nesting, layout, and downstream production constraints. Robustness, Repeatability & Process Improvement: Identify and drive improvements that make printer platforms and additive workflows more robust and repeatable based on machine behavior, failed builds, in-process monitoring data, and hands-on troubleshooting, calibration, and process control improvement efforts. Metal AM Process Support: Partner with internal process and manufacturing teams to optimize and develop all aspects of metal additive manufacturing, especially PBF-LB, including parameter selection, process control, DOE support, process window optimization, and technology maturation. Materials & Process Integration: Work closely with materials and quality teams to investigate properties, geometric accuracy, and surface finish results to help refine print parameters, heat treatments, and manufacturing guidance for existing and new alloys, including aluminum, copper, nickel-based, and other advanced materials as applicable. Post-Processing Integration: Coordinate with internal and external teams across depowder, heat treat, HIP, support removal, machining, finishing, and related secondary processes to ensure end-to-end manufacturability and production readiness. Qualification & Validation Execution: Support qualification planning, validation builds, acceptance criteria definition, and data package development required for customer approval and production release, including alignment with aerospace qualification processes and specifications where required. Data Systems, Traceability & Documentation: Maintain clear engineering documentation, build records, and traceability artifacts, and produce and improve reports, procedures, manuals, and systems that capture results, enable process analysis, and refine development workflows while minimizing administrative burden. Technical Problem Solving: Investigate build, machine, process, and part quality issues using structured root cause analysis and first-principles engineering judgment, and support corrective actions that improve yield, consistency, and equipment performance. Cross-Functional Execution: Work closely with Additive Manufacturing, Manufacturing Engineering, Quality, Materials, Supply Chain, and Operations to industrialize solutions, coordinate with equipment OEMs when needed, and meet customer commitments. Best Practices, Standardization & Safety: Capture lessons learned, develop best practices for equipment and processes, improve standard work and design guidance, investigate new additive technologies that meet business needs, and identify opportunities to improve safety throughout the additive manufacturing workflow. Technical Communication: Present technical recommendations, trade studies, and status updates clearly to internal stakeholders and customers. What We’re Looking For: Bachelor's degree in Engineering, Mechanical, Materials, Aerospace, Manufacturing, Welding, or related field. 4+ years of experience in additive manufacturing, manufacturing engineering, applications engineering, process engineering, or development of metallic additive technologies, preferably in metal AM. Hands-on knowledge of metal additive manufacturing processes, especially PBF-LB, including build planning, support strategy, machine operation, and production considerations. Experience working with engineering drawings, GD&T, tolerance interpretation, and inspection planning. Experience supporting part development from prototype through qualification or early production, including process and application development. Familiarity with DfAM principles and the interaction between part design, print strategy, downstream processing, and manufacturing performance. Strong problem-solving skills with the ability to analyze technical issues, apply sound engineering fundamentals, and recommend practical solutions. Ability to communicate effectively with customers, engineers, technicians, equipment suppliers, and cross-functional teams. Willingness to travel up to 15-20%, primarily within the U.S. U.S. Citizen or Permanent Resident required for ITAR compliance. What Will Set You Apart: Experience supporting aerospace and defense applications in regulated manufacturing environments, including qualification or flight-critical hardware requirements. Experience with process validation, qualification planning, capability studies, statistical process control, or multifactorial DOE. Familiarity with AM standards and specifications, including ASTM, ISO/ASTM, aerospace customer requirements, and qualification documentation practices. Experience with post-processing methods such as heat treat, HIP, machining, support removal, surface finishing, and related secondary or joining processes. Experience with AM build preparation software, CAD tools, simulation tools, data analysis workflows, and PLM or MES environments such as NX, Teamcenter, Manufacturo, or similar systems. Familiarity with in-situ monitoring, sensor data, metallurgical evaluation, CT inspection, optics and laser systems, or advanced characterization methods. Experience contributing to customer design reviews, technical workshops, proposal efforts, and cross-functional collaboration with design, analysis, manufacturing, and quality teams. Exposure to quality systems and production documentation in environments such as AS9100 or equivalent. Experience operating additive machines, supporting parameter development, implementing process control improvements, and troubleshooting or calibrating multi-laser PBF-LB equipment. Experience documenting best practices for new equipment, process changes, or manufacturing methods, with working knowledge of additive, subtractive, and metal joining techniques.
