Job description

Entry Level Wastewater Engineer
Department: Water/Wastewater
Employment Type: Full Time
Location: Hartford, CT
Compensation: $75,000 - $100,000 / year
Description
At Fuss & O'Neill, our mission is to provide clients with innovative, practical engineering, scientific, and planning solutions to meet their needs. We act together as one company, we believe diverse viewpoints make for a stronger team, and we back that belief with real investment in our people's professional growth.
We're looking for an early-career Wastewater Engineer ready to get hands-on with the systems that keep communities running - treatment plants, pump stations, collection systems, and everything in between. This isn't a "watch and wait" entry-level role: you'll be working directly on design, analysis, permitting, and construction support from day one, learning from engineers who actually want to teach you something.
And we're backing that growth with more than good intentions: this role comes with a guaranteed seat in Blueprint, our new early career leadership program. Over six months, you'll build professional development, business acumen, and project delivery skills through real case studies, simulations, and role-play - not passive lectures - culminating in an in-person capstone event where you'll present your work and map out your goals for the year ahead. Your Future Starts With A Plan.
What You'll Do
Under the direction of a Project Manager and/or Lead Engineer, you will:
  • Design wastewater treatment plants, pumping stations, and collection systems
  • Perform hydraulic and process modeling for wastewater systems
  • Prepare engineering reports, technical memorandums, and permit applications
  • Assist with feasibility studies, cost estimates, and construction documents
  • Coordinate with clients, regulatory agencies, and multidisciplinary project teams
  • Support project management, including budgeting, scheduling, and client communication
  • Get out in the field for site visits, investigations, and construction oversight

What You Bring
  • Bachelor's (or graduate) degree in Environmental or Civil Engineering
  • Coursework or internship experience in wastewater engineering - pump stations, collection systems, or treatment - is a strong plus, but we're glad to build on a solid foundation
  • EIT preferred; a path toward PE licensure is a plus
  • Familiarity with AutoCAD and Civil 3D; exposure to HydroCAD, HEC-RAS, or other hydrology/hydraulics modeling software is a bonus, not a requirement

Why You'll Love Working with Us
  • Schedule Flexibility: Customize your work schedule to fit your life.
  • Health & Wellness: Comprehensive health benefits to keep you and your family healthy.
  • Continuous Learning: Access to online courses, conferences, and learning materials to fuel your professional growth.
  • Paid Time Off: Take the time you need to recharge with our generous paid time off policy.
  • Career Advancement: Clear paths for promotions and the opportunity to take on new challenges.
  • Fun Team Culture: Regular team-building activities, happy hours, and company outings.

The base salary range for this role is indicated in the posting. This range reflects the company's good faith estimate of the compensation for this position at the time of posting. Final compensation will be determined based on factors such as experience, skills, qualifications, internal equity, and geographic location.
Visa sponsorship is NOT available for this position
All offers are contingent upon a successful criminal background check. Fuss & O'Neill, Inc. is proud to be an Affirmative Action/Equal Opportunity Employer. Fuss & O'Neill participates in the Federal e-Verify program.
