Role Overview:

This industrial hygiene (IH) role involves being outsourced full time to a specific Apex global icon client. This position reports to a manufacturing facility in St. Louis, MO.

These role requires fairly experienced IH professional. The Certified Industrial Hygienist (CIH) credential is NOT required. Accordingly, relatively inexperienced IH's who would require regular ongoing coaching and mentoring on IH strategy and tactics are not a fit for these roles.

The incumbent will execute IH sampling projects and create reports, deliverables, and path-forward recommendations for management based on the sampling results. This role will routinely involve working 'on the shop floor' with employees, collecting personal dosimetry samples.

Over & above the shop floor sampling activities, the incumbent will also routinely be involved in ensuring the effective ongoing administration of a variety of IH programs. Hence this role involves much more than simply being an IH Technician. It has a significant Program Management / Project Management component as well.

Perhaps most importantly, the incumbent will be a customer driven, energetic self-starter with the ability to work independently. From an interpersonal skillset perspective, the ideal candidate will be outgoing enough to be comfortable engaging in conversations with client personnel of all levels - from shop floor touch labor to first line supervisors to management.

  • Experience in manufacturing-&-assembly industries / heavy industry settings a plus.
  • Experience in the aerospace and defense or automotive industry a further plus.
  • Possess knowledge of occupational IH technical subject matter and how to apply it in real-life settings. Familiar with standard concepts, practices, and procedures within the IH field.
