  • Lead a shift team of 15-25 operators across glass‑cutting, toughening, laminating and insulated‑glass‑unit (IGU) assembly lines, ensuring safe, efficient flow from raw sheet to finished sealed units.
  • Plan daily glass‑cut lists and furnace loads using our optimisation software, balancing yield, cycle time and energy consumption while meeting OTIF targets.
  • Control critical process parameters (edge deletion depth, furnace temperature profiles, spacer application, gas‑fill levels) and intervene quickly to prevent quality escapes.
  • Monitor KPIs such as breakage rate, reject % by defect code, OEE and labour utilisation; launch 5 Why / fish‑bone investigations and Kaizen events to drive scrap reduction.

  • Quality assurance: sign off first‑article samples, oversee destructive testing (e.g., soak‑test on tempered units), and liaise with QA on EN 1279 & BS EN 12150 conformity.
  • Coordinate with Maintenance & Engineering for furnace calibrations, autoclave checks and downtime recovery; support new glass‑technology introductions (e.g., warm‑edge spacer lines, low‑E coatings).
  • Provide clear shift handovers and production reports, highlighting throughput, defects, downtime causes and corrective actions; coach and develop team members with skills matrices and PDPs.

About You

  • Proven experience supervising a manufacturing/assembly team (plastics, window & door, FMCG or similar high‑volume environment).
  • Solid understanding of lean manufacturing tools and production KPIs.
  • Strong people‑management, communication and conflict‑resolution skills.
  • Working knowledge of H&S and quality standards (ISO 9001, ISO 14001).
