What are the key responsibilities of a Heat Treat Engineer?

•Design, develop, and optimize heat treatment cycles (annealing, quenching, tempering, carburizing, nitriding) for ferrous and non-ferrous alloys
•Establish and maintain process parameters, control plans, and equipment settings to ensure part performance and repeatability
•Perform metallurgical analysis (microstructure, hardness, tensile/impact testing) and interpret results to guide process improvements
•Develop and validate thermal profiles using thermocouples, dataloggers, and simulation tools (e.g., FEA thermal models)
•Lead root-cause investigations for heat-treatment-related defects and implement corrective actions to reduce scrap and rework
•Generate and maintain heat-treatment documentation: work instructions, FMEA, control plans, and process capability studies (Cp/Cpk)
•Collaborate with production, QA, design engineering, and suppliers to ensure specifications and AMS/ASTM standards are met
•Manage furnace maintenance schedules, calibration of instrumentation, and supplier qualifications for consumables
•Train operators on best practices, safety protocols, and continuous improvement methodologies (5S, Kaizen, Six Sigma)
•Support new product introduction by developing robust heat-treatment routes and scaling processes for production
