Supervisor, Manufacturing

The MOCVD Manufacturing Supervisor provides immediate, hands‑on supervision and operational support for night‑shift operators and maintenance technicians supporting the GaN MOCVD R&D facility in Goleta, California. The supervisor assigns work, monitors execution at frequent intervals, maintains shift schedules and workflow, and ensures adherence to established safety, quality, production, and equipment procedures. Working within defined operating plans and management guidance, this role responds to routine shift issues, escalates higher‑risk or technically complex problems, and delivers team targets against daily and weekly production plans.

The supervisor routinely works alongside operators and technicians to remove barriers, address production issues, and maintain continuous execution throughout the shift.
