Water Quality Environmental Scientist (Junior-Level)

Environmental Science Associates (ESA) is a 100% employee-owned environmental consulting firm. We plan, design, permit, mitigate, and restore for projects across our communities, infrastructure systems, open spaces, and wildlands. We are 50 years strong in 21 offices across California, the Pacific Northwest, and the Southeastern United States.

ESA is seeking a motivated Environmental Scientist with a focus on water quality and watershed science to join our Southeast team. This junior-level role is ideal for a scientist with 2+ years of experience applying quantitative methods to ecological, hydrologic, and water quality datasets, preferred within Florida’s freshwater and estuarine systems and associated watersheds . The ideal candidate brings a passion for natural systems, analytical skills, and the ability to translate complex datasets into clear, defensible technical work products.

This is an exempt, full‑time, salaried role working a hybrid schedule (2-3 days per week) depending on project needs, out of the Tampa and/or Orlando, FL, offices. Qualified candidates within a commutable distance to other Florida ESA locations may be considered. Strong preference given to candidates able to work hybrid from our Tampa or Orlando ESA offices.
