  • Manage spare parts and tool kits for upgrade projects, performing kitting, inventory reconciliation, and requisitioning of critical long-lead items.
  • Perform contamination control and cleanroom gowning procedures when working on tools in controlled environments, ensuring adherence to particle and chemical handling protocols.
  • Implement and follow statistical process control (SPC) checkpoints and yield monitors to verify that upgrades do not adversely affect product specifications or performance metrics.
  • Document root-cause analyses and corrective actions following upgrade-related failures, participating in CAPA or continuous improvement initiatives to prevent recurrence.
  • Assist in the development and revision of Standard Operating Procedures (SOPs), work instructions, and change control documentation to capture lessons learned from upgrade execution.
  • Train junior operators and technicians on upgraded equipment, new operating sequences, safety protocols, and troubleshooting best practices to ensure consistent team capability.
  • Execute equipment calibration and instrumentation checks after upgrades, coordinating with calibration labs and contractors as needed to maintain measurement integrity.
  • Coordinate with external vendors and OEM service teams for warranty upgrades, vendor-supplied software patches, and complex mechanical/electrical interventions, ensuring vendor work meets company standards.
  • Monitor upgrade-related KPIs — including mean time to repair (MTTR), mean time between failures (MTBF), upgrade lead time, and yield impact — and report outcomes to stakeholders.
  • Ensure compliance with environmental, health, and safety (EHS) regulations during upgrade activities, including chemical handling, confined space rules, and hazardous energy control.
  • Participate in project kickoff meetings and provide practical input on constructability, required manpower, estimated downtime, and risk mitigation strategies for upgrade projects.
  • Validate safety interlocks, emergency stops, and protective systems following mechanical or control changes; conduct functional safety checks prior to production restart.
  • Perform mechanical and electrical alignment checks using laser alignment tools, dial indicators, and precision measurement devices to ensure tool performance post-upgrade.
  • Manage change control packages from initiation through approval, implementation, and closure, ensuring complete traceability and documentation for audits.
  • Support continuous improvement by identifying upgrade opportunities, cost-saving measures, and reliability improvements based on observed failure modes or aging equipment trends.

Secondary Functions

  • Support ad-hoc data requests related to upgrade performance, downtime causes, and parts consumption; assist in assembling reports for engineering and operations leadership.
  • Contribute to the organization's upgrade and maintenance strategy by providing field-level insights into recurring failure modes and upgrade feasibility.
  • Collaborate with business units and process engineers to translate operational needs and production constraints into practical engineering requirements for future upgrades.
  • Participate in sprint planning, project stand-ups, and agile ceremonies when working within multi-disciplinary project teams to deliver upgrades on schedule and within budget.
  • Assist with cost tracking and documentation for upgrade projects, including labor hours, external service charges, and parts costs, to support budget reconciliation.
  • Provide mentoring and hands-on coaching during skill-transfer sessions for cross-functional teams during major upgrade rollouts.
