Project Manager, Water Resources

HR Green

Job Description

Job Description

Join our team! Our mission is BUILDING COMMUNITIES. IMPROVING LIVES. For over 100 years, HR Green has done exactly that, serving as a trusted partner to our Colleagues, our clients, and our communities. Each day, we work to find solutions that inspire our employees and fit our clients' needs to build trust and exceed our clients' expectations. As a leading player in the industry, we're proud to be ranked No. 168 on Engineering News Record's Top 500 Design Firms list in 2025. Our unwavering dedication to cultivating an exceptional workplace environment has earned us the distinguished honor of being recognized as a Great Place to Work.


Lead the projects your community depends on. Shape what comes next.

At HR Green, we help communities grow and thrive through thoughtful infrastructure solutions. This role supports our Water Resources team and collaborates across disciplines — including Water Resources, Potable Water, and Wastewater — giving you a broad view of how systems come together.

As a Project Manager, you’ll lead projects from early strategy through design and construction — guiding teams, partnering with clients, and ensuring successful delivery. You’ll play a key role in shaping solutions that have lasting community impact.

Why This Role Stands Out

  • Lead full project lifecycle (planning → design → construction) 
  • Direct client relationships and project strategy 
  • Manage multiple projects with real community impact 
  • Influence business development and growth opportunities 
  • Lead and mentor project teams 

What You’ll Do

  • Lead the planning, design, and delivery of water resources projects (stormwater, flood mitigation, stream restoration, watershed planning) 
  • Serve as the primary client contact and build long-term client relationships 
  • Develop scopes, budgets, and project schedules 
  • Manage project performance to ensure delivery on time and on budget 
  • Oversee hydrologic, hydraulic, and water quality analyses 
  • Coordinate multidisciplinary teams across Water Resources, Wastewater, and Potable Water 
  • Lead QA/QC processes and uphold design and quality standards 
  • Support business development efforts, including proposals and client presentations 
  • Mentor and guide engineers and project staff 

What We’re Looking For

  • Bachelor’s degree in Civil Engineering (or related field) 
  • ~10+ years of experience in water resources or related field 
  • Professional Engineer (PE) license required 
  • Strong project management experience (scope, budget, schedule) 
  • Experience leading teams and managing client relationships 
  • Background in hydrologic/hydraulic modeling and master planning preferred

Benefits

Not only does HR Green provide you with a place to grow, thrive, and enjoy your work, but we are also dedicated to delivering a comprehensive and multi-faceted benefits package. We invest in our people with a comprehensive total rewards package that supports both your career and your life outside of work, including:

  • Employee ownership opportunities
  • Hybrid and flexible work schedule 
  • Performance-based bonus program
  • Traditional and Roth 401(k) plans with immediate vesting of employer match
  • Tuition reimbursement for continued learning
  • Two days of paid volunteer time each year
  • Medical, dental, and vision insurance coverage
  • Parental leave
  • Onsite Fitness Gym and fitness membership reimbursement
  • Ergonomic desk and office set-ups
  • Covered parking garage 
  • Monthly office events, including Friendsgiving, game nights, holiday celebrations, charitable initiatives, and team offsites
  • Visit our website for detailed total rewards information.

HR Green is proud to be an affirmative action/ equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, veteran status, or other classification protected by applicable federal, state or local law.
