Description

Certified Industrial Hygienist (CIH)

Indoor Science, an Aftermath Services company — Chicagoland, IL | Full-Time

Indoor Science is a 20+ year Chicago-area industrial hygiene and indoor air quality consulting firm — and we're growing. We're looking for a Certified Industrial Hygienist to join our team and help us take on more of the interesting, high-difficulty projects we're known for: asbestos, lead, mold, indoor air quality, and the occasional genuinely strange investigation that requires real detective work to solve.

What You'll Do

Conduct field investigations for indoor air quality, mold/moisture intrusion, asbestos, and lead across a wide range of residential, commercial, and industrial sites.
Design sampling strategies, interpret results, and write clear, client-ready reports.
Work directly with clients — property owners, facility managers, contractors, and insurers — as a trusted technical advisor.
Take on unique, one-off projects that require creative problem-solving, not just a checklist.
Sign off on technical work performed by junior team members.

What We're Looking For

Active CIH strongly preferred — but if you're actively working toward your CIH (exam scheduled or in progress), we want to hear from you.
Illinois Asbestos Inspector and Air Sampling licenses, or the ability to obtain them shortly after hire.
A degree in Environmental Health & Safety, Occupational/Environmental Hygiene, Environmental Engineering, Physics, Chemistry, or Biology.
Comfort with the consulting side of the work — talking to clients, scoping projects, and building relationships.
Willingness to travel regionally (50%+) and be based in the Chicagoland area.

Why Join Indoor Science

A clear, company-supported path to CIH certification if you're not there yet — we cover the prep training.
Genuine variety of work — we see more unique and challenging projects than most firms in this space.
20+ years of industry reputation and stability, now backed by Aftermath Services.
Real room to grow as our team scales.
