Contaminant Hydrogeologist

Job Description

Posted Monday, April 27, 2026 at 8:00 AM

Are you the kind of environmental professional who doesn't just characterize contaminated sites, but quietly shapes how they get managed, remediated, and closed out?

If you're at your best when you're deep in the data, leading Phase I and Phase II ESAs, mentoring the next wave of scientists and engineers, and bringing technical rigor to every report that leaves your desk, this role is your next career step!

This isn't a back-office technical reviewer position. You'll sit at the intersection of science, regulation, and client service, leading complex site investigations across Alberta while helping the next generation of environmental professionals grow on our team.

You'll be trusted to take ownership of complex sites, challenge interpretations where needed, and help clients and operational leaders navigate Alberta's regulatory landscape without losing sight of the technical detail that drives defensible outcomes.
