Certified Industrial Hygienist

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.
