Senior Infrastructure Engineer - Shape the Future of Water Systems

Not Specified

Design the systems that keep communities running

You’re an experienced civil or environmental engineer who wants your work to matter every single day. Here, you’ll plan, design, and help deliver the water, wastewater, and stormwater infrastructure that keeps cities healthy and resilient.

You’ll own challenging projects outside the treatment plant fence line – pipelines, pump stations, trenchless installations, lift stations, and more – from concept through construction support.

Your designs will move millions of gallons safely and reliably. Your judgment will shape critical infrastructure decisions.

If you’ve been deep in water and wastewater infrastructure and are ready for a bigger stage, we want to talk to you.

What You'll Work On

You’ll be a key engineer on multidisciplinary water infrastructure projects, from planning studies to engineering services during construction:

• Water transmission and distribution pipelines
• Wastewater and stormwater conveyance systems
• Pump stations and wastewater lift stations
• Conceptual and preliminary design studies
• Technical reports, memoranda, and project documentation
• Civil engineering plans, specifications, and cost estimates
• Construction-phase engineering support for infrastructure projects

This is where complex water, wastewater, and stormwater challenges become real-world, buildable solutions.

What You'll Be Doing

• Serving as an engineer on planning, design, construction, and commissioning of water, wastewater, and stormwater infrastructure projects
• Specializing in pipelines, pump stations, trenchless pipelines, wastewater lift stations, and related infrastructure outside treatment plants
• Performing conceptual and preliminary design, including site visits and overseeing fieldwork
• Leading alternatives analysis and preparing planning and design reports
• Developing civil engineering plans and technical specifications
• Preparing detailed cost estimates for water and wastewater infrastructure projects
• Producing technical memoranda, reports, and electronic deliverables
• Assisting the project manager with planning, scheduling, and coordinating project team activities
• Helping supervise and review work of environmental, civil, structural, mechanical, electrical, I&C, drafting, technical, and subconsultant staff
• Supporting project budget, schedule, and quality goals
• Reviewing contractor submittals for conformance with contract documents
• Evaluating RFIs and providing engineering services during construction

What We're Looking For

• Bachelor’s degree in Civil or Environmental Engineering
• 8 to 15 years of directly relevant experience in water and wastewater infrastructure
• Registration as a Professional Engineer
• Strong application of engineering principles, including critical thinking and analysis
• Ability to apply innovative techniques to complex infrastructure projects
• Strong verbal and written communication skills with clients and project teams
• Proven success working in a team environment
• Highly motivated, articulate, and self-starting mindset

The Experience That Will Really Get Our Attention

You’ve been the go-to engineer for complex conveyance projects – from planning and alternatives analysis through design packages and construction support. You’re comfortable coordinating with multiple disciplines and translating field conditions into constructible designs and clear documents.

Maybe you’ve taken on informal leadership and PM support, guiding junior staff and helping keep budgets and schedules on track, and you stay plugged into the water sector through professional associations or advanced study.

High-signal experience:

• water pipelines
• wastewater pipelines
• stormwater conveyance
• pump stations
• wastewater lift stations
• trenchless pipeline design
• civil plans and specifications
• cost estimating
• engineering services during construction

Why This Opportunity?

This is a senior-level role with direct impact on critical water, wastewater, and stormwater infrastructure for public agencies, utilities, and private clients across sectors.

You’ll collaborate with specialized engineers across environmental, structural, mechanical, electrical, and controls, while still having clear ownership over key planning and design work.

You’ll deepen your expertise on challenging, diverse projects outside the treatment plant, from trenchless installations to major pump stations, with room to grow your project management responsibilities over time.

On top of competitive compensation, you’ll have access to a comprehensive benefits program, including paid time off and holidays, health coverage, savings account options, insurance offerings, caregiver support, counseling services, discount programs, a lifestyle reimbursement account, retirement contribution matching, tuition reimbursement, multiple bonus opportunities, and potential flexible work arrangements (eligibility varies by status).

Travel may be required depending on the project assignment, but most projects are local.
