Scope of the Role

The Assembly Operations Supervisor ensures assembly work is planned, staffed, and executed to meet quality, delivery, and continuous-improvement goals. This role exists to keep daily production aligned with customer commitments while maintaining safe, organized operations.

Key responsibilities include building and maintaining production schedules, tracking departmental KPIs and reporting status in leadership meetings, managing staffing levels, and using the ERP system to produce schedules, maintain production data, and complete required reporting. You will oversee inventory accuracy (cycle counts and transactions across raw, WIP, and finished goods), support setup/assembly as needed, and drive cost-reduction and process-improvement actions.

Daily Operating Rhythm

You start by reviewing the day’s schedule, current backlog, and any shipping deadlines, then confirm priorities with leads and supporting departments. Throughout the shift, you check progress against plan, update ERP data and simple Excel trackers, and address issues that could affect on-time delivery or quality. You’ll spend time on the floor observing workflow, answering questions, and reinforcing safe practices and good housekeeping. Midday often includes quick check-ins to align materials and inventory accuracy, followed by brief huddles to keep communication clear. Before wrap-up, you document status, note constraints, and prepare updates for leadership so the next shift begins with an accurate, controlled plan.
