Job Description

Mid-Level Water/Wastewater Engineer

Orange County, CA (On-Site)

Join a fast-growing engineering team focused exclusively on water, wastewater, and infrastructure projects that directly impact communities and sustainability .

This is a true design-forward role — ideal for engineers who want to stay hands-on technically , not get pulled into purely administrative project management.

You’ll work on a mix of:

• Advanced treatment systems
• Municipal pipeline and conveyance infrastructure
• Recycled and potable water systems

…and have the opportunity to own your work from concept through construction.

• Design and analyze water and wastewater systems (treatment OR infrastructure)
• Perform hydraulic modeling and engineering calculations (WaterGEMS, SewerGEMS or similar)
• Prepare:
  • Construction documents (plans, specs, estimates)
  • Technical reports and design memos
• Support permitting efforts (SDWA, NPDES, Title 22) (
• Collaborate with:
  • Engineers, CAD teams, and project stakeholders
• Gain exposure to:
  • Fieldwork, site visits, and construction support

This is not a “support role” — expectation is owning technical design and contributing immediately .

• 5–15 years of experience in water/wastewater engineering
• PE license (or ability to obtain)
• Experience in ONE of the following areas :
  • Treatment systems (process design, plants)
  • Conveyance/infrastructure (pipelines, pumping, storage)

• Hydraulic calculations + modeling
• System design ownership (not just coordination)
• Technical report writing
• Ability to work independently and direct design work

• Primarily work in land development or general civil
• Have a stormwater-only or non-water
• Focus more on project coordination than design
• Cannot clearly explain engineering decisions or calculations

This role is specifically for engineers who design, not just review or manage .

• Experience with InfoWater, BioWin, or similar tools
• Municipal or water district project experience
• Exposure to permitting and regulatory coordination
• Mentorship or leadership experience

You’ll have a clear path toward:

• Project Management
• Technical Leadership
• Hybrid or custom career tracks

You’ll also gain exposure across both:

• Treatment operations (“inside the plant”)
• Infrastructure systems (“outside the fence”)

…allowing you to shape your long-term direction.

• Stay technical — not forced into PM too early
• Work on high-impact water projects
• Join a collaborative, design-focused team
• Build long-term career depth in a stable, growing market

If you’re an engineer who wants to own design, stay hands-on, and work on meaningful water infrastructure projects , this is the role.
