Field Service Technician (FST) – Environmental Services

All City Environmental (An LES Company)
Location: Chicago, IL

Build a Career with All City Environmental

All City Environmental, a proud part of Liquid Environmental Solutions (LES), is a leader in environmental and wastewater services throughout the Chicago market. We specialize in keeping businesses compliant, operational, and environmentally responsible through essential services like grease trap cleaning, hydro jetting, vacuum truck services, and wastewater system maintenance.

We are looking for Field Service Technicians (FSTs) who want more than just a driving job—this is a hands-on, skilled trade role where you’ll operate specialized equipment, solve real problems for customers, and build a long-term career in a stable, growing industry.

Position Overview

The Field Service Technician (FST) is responsible for performing on-site environmental services for commercial and industrial customers. This includes operating vacuum trucks, jetting equipment, and related tools to clean and maintain grease traps, drains, and wastewater systems.

This is a customer-facing, field-based role requiring mechanical awareness, problem-solving ability, and a strong commitment to safety and compliance.

What You’ll Do

Field Operations

• Perform grease trap cleaning, hydro jetting, and wastewater system services


• Operate vacuum trucks and high-pressure water systems


• Safely transport and dispose of non-hazardous liquid waste


• Set up and secure work areas (cones, barriers, safety protocols)

Customer Service

• Interact directly with customers on-site


• Represent All City Environmental professionally at all times


• Communicate service findings and recommend solutions when needed

Equipment & Compliance

• Conduct pre- and post-trip inspections of vehicles and equipment


• Maintain clean, organized trucks and work areas


• Complete service documentation accurately


• Follow all DOT, OSHA, and environmental regulations

What We’re Looking For

• CDL License


• 1 year of verifiable CDL experience


• Ability to work in physically demanding environments (lifting, bending, outdoor work)


• Strong work ethic and reliability


• Comfort working in wastewater, grease, and industrial environments

Preferred (Not Required)

• Experience in plumbing, drain cleaning, septic, or environmental services


• Experience operating vacuum trucks or jetting equipment


• Mechanical aptitude or hands-on trade experience

Compensation & Schedule

• Hourly Pay: Competitive based on experience


• Overtime: Frequent overtime available (typical 50–60 hours/week)


• Schedule: Early start times; flexibility required based on customer needs

Why This Role Stands Out

• Stable, essential industry – year-round work


• Skill-based career path – learn multiple service lines


• Hands-on work – no two days are the same


• Growth opportunities within All City Environmental and LES nationwide
