• Independently partner with engineering, facilities, and operations leadership on a weekly cadence to:
  • Identify emerging EHS risks
  • Challenge unsafe designs or practices
  • Establish measurable corrective actions tied to site KPIs
• Lead complex incident investigations, high-potential near-miss reviews, and significant non-conformances using structured, data-driven problem-solving methodologies (e.g., fault tree, barrier analysis, trend analysis).

• Prepare and submit technically accurate EHS reports and permit documentation, defending assumptions and methodologies when challenged.
• Represent the site during regulatory inspections, technical discussions, and enforcement-related inquiries with confidence and credibility.

• Bachelor’s degree in Engineering or Applied Science (Chemical, Environmental, Mechanical, Electrical, Industrial Hygiene, or equivalent).
• 6+ years of progressively responsible experience in:
  • Semiconductor manufacturing environments or
  • High-hazard industrial facilities with complex tools, chemical systems, and construction activity
• Proven, hands-on working knowledge of:
