Training Supervisor

At Senra Systems, we believe that the future of manufacturing lies not in automation, but in configuration. We supercharge electrical wire harness manufacturing through software configuration, transforming skilled assembly tasks into high-throughput production lines. We enable customers to design what they want, when they want it and deliver harness builds at record-breaking speed. At Senra Systems, our ability to scale hinges on building a workforce of exceptional technicians and that starts with a world-class training program. As the Training Supervisor, you’ll own that program end to end: leading a team of Technical Trainers, shaping curriculum, ensuring compliance with aerospace and defense standards, and measuring what actually moves the needle. This role is for a builder and leader who is equally comfortable on the production floor and in a planning meeting. You set the standard, develop the people who deliver it, and have the data to back it up. What you'll own: Program Leadership & Curriculum Ownership Own the full training program lifecycle from onboarding through advanced certification for apprentice and harness+ technicians. Develop, maintain, and continuously improve training curriculum, SOPs, and assessment tools to reflect current engineering drawings, quality standards, and customer requirements. Design structured learning paths that balance classroom fundamentals with on-the-job (OTJ) reinforcement, ensuring every trainee exits prepared for Day 1 on the floor. Establish and maintain a master training library, keeping materials version-controlled and audit-ready. Evaluate program effectiveness using trainee performance data, first-pass yield, and production team feedback; iterate quickly when gaps appear. Team Leadership & Trainer Development Directly supervise and develop a team of Technical Trainers, setting clear expectations, providing ongoing coaching, and conducting performance reviews. Build trainer capacity through structured observation, feedback loops, and shared best practices that elevate the whole team. Own scheduling and workload allocation across the training team to support production ramp, onboarding cycles, and cross-training initiatives. Identify and close skill gaps within the trainer team, creating development plans that grow their technical and instructional capabilities. Foster a culture of accountability, psychological safety, and continuous improvement within the training function. Compliance & Certification Management Serve as the internal subject matter expert on IPC/WHMA-A-620 and other applicable aerospace and defense standards; ensure all training content stays current with standard revisions. Own technician certification tracking — maintain accurate records, manage renewal cycles, and ensure compliance across the workforce. Prepare the training program for internal audits, customer audits, and AS9100/NADCAP reviews; lead training-related corrective actions when findings arise. Partner with Quality and Engineering to ensure training content reflects the latest drawing revisions, customer specifications, and non-conformance trends. Maintain all training records in the ERP/MES system with the accuracy and completeness required for regulatory and contractual compliance. Metrics & Reporting Define and own key training KPIs: time-to-certification, trainee throughput, first-pass yield by cohort, certification compliance rates, and trainer utilization. Deliver regular reporting to Operations and People leadership that connects training outcomes to production performance and quality metrics. Use data to make the case for program investments, headcount, and curriculum changes — and to proactively flag risks before they hit the floor. Maintain a real-time view of training pipeline capacity to support workforce planning and production scheduling.
