THE ROLE

The Senior Water Resources Project Manager leads the planning, design, and delivery of water resource engineering projects that protect communities and strengthen local infrastructure. In this role, you will develop science‑based engineering solutions that integrate infrastructure with the natural environment—advancing flood mitigation, stormwater management, watershed protection, irrigation, and the rehabilitation of critical water systems.

• Direct preparation and QA/QC of plans, specifications, cost estimates, technical reports, and FEMA or permitting submittals.

• Develop engineering approaches, alternatives analyses, and recommendations that balance technical performance, cost, constructability, and environmental stewardship.

• Manage full project lifecycle: scope development, budgeting, scheduling, resourcing, risk identification, and change management.

• Coordinate multidisciplinary teams to ensure integrated and timely project delivery.

• Lead construction-phase services including RFIs, submittal reviews, field observations, and resolution of design‑related issues.

• Maintain accurate project documentation, progress tracking, and financial performance reporting.

• Provide mentorship, technical guidance, and performance feedback to junior engineers and EITs.

• Delegate tasks effectively and support staff development through coaching, training, and design reviews.

• Champion company QA/QC standards, ensuring accuracy, consistency, and quality across project deliverables.

• Identify new opportunities, support client account growth, and help develop strategic pursuits.

• Lead or contribute to proposal development, including scopes, schedules, level of effort, and interview participation.

• Make key technical and delivery decisions, balancing risk, cost, constructability, and regulatory requirements while guiding the team to successful outcomes.
