Environmental Scientist Jobs in Missouri: Frequently Asked Questions
How do you become a environmental scientist in Missouri?
Most environmental scientist positions in Missouri require at minimum a bachelor's degree in environmental science, geology, chemistry, or a related field. Missouri does not mandate a single state license for the title, but many employers require or strongly prefer candidates who hold a Professional Geologist license issued by the Missouri Board of Geologist Registration for subsurface and remediation work. Gaining field experience through internships with Missouri DNR or environmental consulting firms significantly strengthens a candidate's profile.
How much do environmental scientists make in Missouri?
Environmental scientists in Missouri earn a median of about $61,050 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $49,140 for the lowest 10% to over $88,710 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire environmental scientists in Missouri?
Companies currently hiring environmental scientists in Missouri include Burns & McDonnell, WSP, and Olsson, per current listings on Migrate Mate as of August 2026. Missouri's mix of large engineering consultancies, state agency offices, and industrial manufacturers across the St. Louis and Kansas City corridors keeps demand for environmental scientists consistent throughout the year.
Which Missouri cities have the most environmental scientist jobs?
Kansas City and St. Louis have the most environmental scientist openings in Missouri. St. Louis anchors much of the demand through its concentration of engineering and environmental consulting firms and proximity to major industrial sites along the Mississippi River, while Kansas City draws openings from infrastructure and municipal utility projects, and Jefferson City generates consistent postings through state agency work at Missouri DNR.
How can I get hired as a environmental scientist in Missouri with little or no experience?
The most realistic entry path is applying to field technician or environmental technician roles, which require a relevant degree but not years of experience, at consulting firms like Terracon or Stantec operating in Missouri.

Earning a Hazardous Waste Operations certification and building GIS skills through coursework gives candidates a measurable edge, as does any capstone project, field practicum, or water quality research completed through a Missouri university environmental program.
