Water Resources Manager

Job Overview:

APTIM, a leading engineering and resilience consulting firm with a global presence and a rapidly expanding Infrastructure Adaptation and Climate Resilience practice, is seeking a Water Resources Manager to join our multidisciplinary team.

This position plays a strategic role in delivering risk-informed design solutions and advancing the integration of resilience into flood control, urban infrastructure, and waterfront systems. The ideal candidate brings a balance of technical depth and project management experience--able to guide multi-sector clients through climate adaptation, vulnerability assessment, and resilient design implementation.

This is a high-growth opportunity to lead complex projects, mentor emerging engineers, and shape the next generation of resilient infrastructure across Florida and the broader Southeast.

Key Responsibilities/Accountabilities:

• Lead and support the watershed master plans, stormwater improvement programs, and climate-resilient infrastructure designs from concept through implementation.
• Manage full scope including financials, staffing, schedule, and subcontractors while serving as the primary client liaison and ensuring technical excellence in reports, presentations, and stakeholder coordination.
• Conduct and oversee hydrologic and hydraulic modeling using tools such as HEC-RAS, HEC-HMS, ICPR, SWMM, or StormWise, integrating future climate and sea-level rise projections.
• Evaluate flood mitigation and drainage improvement alternatives, develop conceptual and preliminary engineering designs, and support cost-benefit and prioritization analyses.
• Apply technical expertise to assess vulnerabilities, quantify flood risk, and identify adaptation strategies for urban and coastal systems.
• Perform benefit--cost analyses and resilience ROI evaluations to guide capital investment decisions.
• Lead and contribute to quality assurance reviews of large datasets and modeling outputs to ensure accuracy and defensibility.
• Integrate engineering, planning, GIS, and digital modeling tools to produce actionable resilience roadmaps and business cases.
• Oversee preparation of technical reports, grant deliverables, and permitting documentation.
• Conduct stakeholder meetings, public workshops, and presentations to communicate technical findings to diverse audiences.
• Support business development and proposal writing, including scoping, pricing, and client engagement.
• Stay current on federal and state resilience policies, design standards, and funding programs (e.g., FDEP Resilient Florida, FEMA BRIC, CDBG-MIT).

• Bachelor's or Master's degree in Civil, Coastal, Structural, or Environmental Engineering, or related field.
• 10--14 years of experience in water resources, watershed master planning, flood adaptation, or infrastructure resilience.
• Experience developing stormwater and flood-mitigation designs within urban, coastal, or estuarine environments.
• Strong understanding of drainage, erosion control, building envelope hardening, and nature-based mitigation systems.
• Strong technical writing and report leadership experience across multi-disciplinary projects.
• Proficiency in GIS, climate data tools (e.g., NOAA SLR Viewer, USACE projections), and Microsoft Excel or Power BI.
• Familiarity with FDEP Resilient Florida, FEMA, BRIC, CDBG-MIT, and other resilience funding mechanisms.
• Experience supporting permitting, design, or construction of resilient infrastructure preferred.
• Ability to work both independently and collaboratively in remote and hybrid teams.
• Professional Engineer (PE) licensure preferred.
• Willingness to travel occasionally to support regional client needs.
• Preferred office locations are in Boca Raton, Jacksonville, Winter Garden or Tampa, Florida.

Preferred Skills:

• Experience leading municipal or regional watershed master plans and developing implementation-ready capital improvem
