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.
Cross-Functional Leadership - Act as the strategic interface between the training function and Engineering, Quality, and Production leadership - ensuring training is a driver of throughput and quality, not a bottleneck.
- Collaborate with People/HR on workforce planning, new hire onboarding sequencing, and internal mobility pathways for technicians.
- Champion the training program's role in Senra's scale strategy - bringing visibility to wins, surfacing systemic challenges, and advocating for necessary resources.
What you'll bring to the team: - 10+ years of hands-on experience in wire harness assembly or similar electro-mechanical manufacturing.

- Deep familiarity with IPC/WHMA-A-620 and aerospace/defense quality standards.
- Proven ability to build and manage structured training programs - curriculum design, documentation, and assessment.
- Strong communication skills: able to present to leadership, coach trainers, and hold technicians accountable - all with the same credibility.
- Comfortable with data - able to track, interpret, and act on training metrics without needing to be an analyst.
