Responsibilities
The biggest blocker on the weekend is often the "knowledge gap." You will actively train and develop new technicians on critical, high-precision operations
Translate complex engineering requirements into teachable moments on the floor. If a technician is unsure, you don’t just give an order; you explain the •why• and show them the •how•
Troubleshoot non-conformance issues in real-time
You determine the severity of the issue. If it’s a simple process drift, you fix it. If it’s a design flaw or critical failure, you contain the issue, document it via Jira, and escalate it to the appropriate Subject Matter Experts (SMEs) rather than applying a "band-aid" fix that compromises the magnet's integrity
Act as the critical feedback loop between the weekend execution team and the weekday Design and Manufacturing teams
When you encounter a process that is vague or impossible to execute, you red-line the work instructions and drive the change request to ensure the weekday team can update the process
Maintain the rhythm of the line. Ensure hand-offs between shifts are seamless and that the team has the tools and materials to hit targets
