Lead Manufacturing Engineer - Motors Castelion is seeking a Lead Manufacturing Engineer to own all aspects of solid rocket motor production. In this role, you will lead a cross-functional team responsible for the safe, repeatable, and rate-capable manufacture of solid propellant motors, from propellant mixing through final acceptance. You will drive aggressive cost, quality, schedule, and safety targets in an energetics manufacturing environment while scaling production for mission-critical programs. CORE RESPONSIBILITIES Manufacturing Leadership and Execution. Lead a team of manufacturing engineers in the daily execution of solid rocket motor production, including propellant mixing, casting, case bonding, and proof/acceptance testing. Ensure on-time delivery of flight hardware while maintaining zero safety incidents and full compliance with DoD regulations. Process Ownership and Continuous Improvement . Own the entire solid motor manufacturing value stream. Develop, qualify, and continuously improve processes, tooling, and facilities to increase throughput, reduce labor hours, and achieve first-pass yield targets. Implement automation, digital thread/MES, and advanced inspection techniques to support rapid production scaling. Technical Authority and Customer Interface. Serve as the primary technical interface to Design Engineering, Program Management, Quality, EHS, and the customer on producibility, non-conformances, and anomaly resolution. Lead root-cause and drive robust corrective actions for defects or process escapes. New Product Introduction and Capacity Expansion .
