We’re seeking an experienced Water/Wastewater Project Manager to join our team, leading municipal water and wastewater infrastructure projects from planning and design through construction.

What You’ll Lead:

• Lead multidisciplinary teams through the full project life cycle; planning, alternatives analysis, design, permitting, bidding, construction support, commissioning, and closeout.
• Manage water and wastewater infrastructure projects such as treatment facilities, pump and lift stations, storage facilities, distribution and collection systems, conveyance pipelines, utility planning, modeling, and rehabilitation improvements.
• Serve as a trusted client partner and primary point of contact, helping public agency and utility clients navigate technical, regulatory, budget, schedule, and stakeholder considerations.
• Develop and manage scopes, schedules, budgets, risk strategies, technical deliverables, and quality expectations to keep projects moving forward successfully.
• Provide technical leadership and QA/QC review for plans, specifications, opinions of probable cost, reports, permits, and construction-phase engineering support.
• Mentor and coach engineers, designers, and emerging project managers while creating a collaborative, accountable, and growth-minded team environment.
• Support business development through client relationship building, proposal strategy, interviews, presentations, networking, and identification of new and repeat work.
• Help clients pursue state, federal, and other funding opportunities that make critical infrastructure improvements possible.

What We’re Looking For:

• B.S. in Civil Engineering, Environmental Engineering, or a related field.
• Professional Engineer (PE) registration in California (or ability to obtain such a license within three months)
• 8+ years of progressive civil engineering experience, preferably focused on municipal water, wastewater, utilities, treatment, conveyance, or related infrastructure projects.
• Demonstrated experience managing project scope, schedule, budget, quality, client communication, and multidisciplinary delivery teams.
• Strong technical background in project delivery from conceptual planning through detailed design, permitting, bidding, and construction support.
• Experience preparing proposals, scopes of work, budgets, cost estimates, technical reports, plans, specifications, and client presentations.
• Ability to communicate effectively with clients, regulatory agencies, contractors, subconsultants, internal teams, and community stakeholders.
• A leadership style that balances technical confidence with collaboration, mentorship, accountability, and a genuine interest in helping others grow.

Why You’ll Love Working Here:

• Work that matters: design infrastructure that supports clean water, public health, environmental protection, and resilient communities.
• Work alongside experienced leaders in a culture that values growth, mentorship, and giving employees the opportunity to help shape the next chapter of a well-established local practice. Flexible schedule that supports both client service and work-life balance.
• Medical, dental, vision, and HSA options.
