Take our internal test lab from concept to day-to-day operation. You’ll help select and qualify equipment, establish test methods and procedures, develop calibration and maintenance requirements, and train others to use the equipment correctly. Capabilities will include particle size distribution, porosity characterization, mechanical testing, and microstructural analysis.\n\nLead hands-on material and process qualification. Develop and execute qualifications for stainless steel, nickel, titanium, aluminum, and other alloy systems. You’ll work directly with AM processes and equipment to establish parameters, run trials, evaluate results, and qualify processes to customer and industry requirements, including AMS, ASTM, and SAE standards.\n\nTroubleshoot real manufacturing problems. When a build, material, or test result doesn’t meet expectations, you’ll help determine why. You’ll use metallurgical analysis, process data, structured experimentation, and hands-on investigation to identify root causes and implement practical corrective actions.\n\nOwn qualification from planning through execution. Lead IQ/OQ/PQ activities, DOE-based studies, process-window development, validation testing, documentation, and technical reporting. You’ll manage multiple qualification efforts and be accountable for driving them through completion.\n\nPartner directly with manufacturing. Work closely with engineering, quality, and production to translate metallurgical requirements into processes that work on the shop floor. You’ll help establish build and validation documentation in ProShop ERP and develop practical training for the team.\n\nAdvance our AM capabilities. Identify better ways to qualify materials, validate processes, evaluate results, and solve emerging technical challenges as Rennscot’s additive manufacturing business grows.\n\nWhat We're Looking For\nWe are open to a range of educational backgrounds - what matters most is what you have done and the impact you have made.\n12+ years (H.S. Diploma) | 10+ years (A.A.) | 5+ years (Bachelor's) | 3+ years (Master's) | Ph.D.\n\nA bachelor's or master’s in metallurgical engineering, materials science, or a closely related field is preferred.\n\nDirect, hands-on experience with metal additive manufacturing processes such as laser powder bed fusion, DED, or binder jetting\n\nExperience developing, qualifying, or improving AM materials and manufacturing processes in an industrial environment\n\nPractical experience troubleshooting AM builds, material issues, defects, or process variation\n\nHands-on metallurgical testing experience, including microstructural analysis, porosity, mechanical testing, and/or powder characterization\n\nExperience working with stainless steel, nickel, titanium, aluminum, or similar alloy systems\n\nExperience executing process or equipment qualification, including IQ/OQ/PQ or comparable validation methodologies\n\nWorking knowledge of AMS, ASTM, SAE, customer specifications, or similar manufacturing standards\n\nExperience using DOE, statistical analysis, and process data to make manufacturing decisions\n\nAbility to translate metallurgical principles - including solidification, phase transformations, microstructure, and defect formation - into practical process decisions\n\nExperience documenting qualification activities, test results, technical findings, and recommendations that can withstand internal and customer review\n\n· Experience standing up or operating a metallurgical lab, working in aerospace or another highly regulated manufacturing environment, and qualifying AM processes for production applications is strongly preferred.\n\nJob Type: On-Site\nJob Location: Woburn, MA. At this time, we are only considering applicants within a 100-mile radius.
