Day 1 on the Process Engineer path.

What a Process Engineer does

Improves factory and industrial processes so products are made safely, consistently, and at lower cost.

  • Analyze production data to find waste, defects, and bottlenecks
  • Design process changes to improve yield, cycle time, and quality
  • Run experiments and trials to validate new settings and materials
  • Create and update work instructions, control plans, and SOPs
  • Troubleshoot equipment and process issues with operators and maintenance
  • Set up process monitoring using sensors, charts, and alarms
  • Support new product launches by defining stable production steps

A day in the life

  1. Review yesterday yield, scrap, downtime, and safety incidents
  2. Walk the line to observe issues and talk with operators
  3. Test a process change and record results from the trial run
  4. Meet with quality and maintenance to close out root causes
  5. Update documentation and plan the next improvement experiment

Tools you will use

Spreadsheets: Excel, Google SheetsStatistics: Minitab, JMPProcess improvement: Lean, Six SigmaProcess mapping: Visio, LucidchartControl systems: PLC, SCADADocumentation: SOPs, control plans
