This role provides senior‑level occupational health and safety expertise to one of Apex's most valued clients, a national aerospace manufacturer. For over 25 years, Apex has partnered closely with this client to achieve their Occupational Health, Ergonomics, and Safety Engineering goals.

The Senior Industrial Hygienist (Sr. IH) will serve as the primary IH lead on the shop floor at the client's Wichita, Kansas facility, working under the direction of the on‑site Certified Industrial Hygienist (CIH). This is a full‑time, on‑site position (5 days per week, 8‑hour day shift) for an initial 6‑month period, with possible extension based on performance and client needs.

The incumbent will provide day‑to‑day IH oversight and coordination on the shop floor, translating CIH program direction into actionable field tasks for mid‑level IH staff and technicians. This role includes conducting complex field evaluations, mentoring junior IH staff, ensuring data quality and proper field practices, and serving as a key liaison between the CIH and production teams.

The ideal candidate will bring strong technical IH competency, practical field experience, effective mentoring skills, and the ability to manage competing priorities in a fast‑paced manufacturing environment. A proactive, collaborative approach and strong communication skills are essential.

As a fixed‑term engagement, this position is authorized for 6 months, with potential extension based on performance and client requirements.

• Serve as the primary IH lead on the shop floor under the direction of the CIH, providing day‑to‑day IH oversight and coordination.
• Translate CIH program direction into actionable field tasks for mid‑level IH staff and technicians, ensuring sampling and assessments are executed as intended.
• Conduct higher‑level qualitative exposure assessments and complex field evaluations, confirming or refining exposure scenarios identified by mid‑level IH staff.
• Review sampling strategies, task groupings, and monitoring plans prepared by mid‑level IH staff and recommend adjustments to the CIH as needed.
• Perform spot checks and validation sampling to verify data quality, representativeness, and proper use of methods, equipment, and PPE in the field.
• Mentor and coach mid‑level IH staff and other EHS personnel on IH fundamentals, field practices, and interpretation of results, escalating more complex technical questions to the CIH.
• Provide preliminary interpretation of exposure data versus regulatory and internal limits and summarize key findings for CIH review and final sign‑off.
• Work closely with production and engineering teams to verify that engineering and administrative controls are implemented and function as described in IH and EHS plans.
• Help track IH‑related corrective actions and projects (controls, sampling campaigns, program updates), ensuring mid‑level IH staff have clear priorities and timelines.
• Supply concise, field‑based status updates, emerging issues, and trend information to the CIH and EHS leadership to support higher‑level program decisions.

• The incumbent will carry a great deal of creativity and have a self‑starter mentality. This position entails routine ongoing work and collaboration with numerous customer stakeholders—all of whom need to be "satisfied" with respect to project purpose, scope, and tactics.
