Our strong backlog includes water and wastewater treatment projects, creating opportunities to build your experience across treatment technologies and grow in the areas that interest you. Gainesville is the preferred location to support mentoring and coordination with our design teams.

You’ll work with a core team of water and wastewater engineers and designers to develop process mechanical systems for treatment facilities. Your work will help clients address technical challenges through practical, coordinated designs. You’ll also have opportunities to support construction, collaborate with technical experts across Jacobs, and contribute to projects in the region, across the United States, and internationally.

What you’ll do

• Develop process mechanical designs for water and wastewater treatment facilities, pump stations, and related infrastructure.
• Evaluate and select process equipment, pumping systems, piping materials, valves, and other mechanical components based on project requirements.
• Perform and review hydraulic calculations and analyses for process piping and pumping systems.
• Develop facility layouts, process flow diagrams, and process and instrumentation diagrams (P&IDs).
• Prepare and review construction documents, including mechanical drawings, equipment schedules, technical specifications, and design calculations.
• Coordinate mechanical designs with civil, structural, electrical, instrumentation and controls, process, and architectural disciplines.
• Analyze project and operational data, identify design issues, and recommend solutions to technical challenges.
• Prepare technical memoranda, reports, design documentation, and other project deliverables.
• Support construction services, including reviewing shop drawings and submittals, responding to requests for information, and assisting with site observations and equipment startup as needed.
• Communicate with clients and project teams to understand project needs, present design recommendations, and help resolve technical questions.
• Contribute to project delivery and quality reviews, and support the development of junior engineers and designers.

• Bachelor’s degree in Mechanical, Civil, Environmental, or a related engineering discipline.
• Professional Engineer license in Florida, or the ability to obtain Florida licensure within 12 months.
• Four or more years of progressive engineering and project delivery experience related to water, wastewater, or industrial treatment systems.
• Experience with process mechanical system planning, evaluation, and design.
• Strong interest in the design and operation of process mechanical systems for water and wastewater facilities.
• Strong analytical, technical problem-solving, organizational, and communication skills.
• Ability to manage multiple assignments and contribute effectively in a fast-paced, team-oriented environment.
• Proficiency with Microsoft Word, Excel, and PowerPoint.
• Ability to collaborate successfully with remote teams in the United States and internationally.

Ideally, you’ll also have

• Experience with municipal water or wastewater treatment plants, pump stations, or conveyance systems.
• Three or more years of direct process mechanical design experience on water or wastewater treatment projects.
• Hydraulic modeling experience with tools such as AFT Fathom or Pipe-Flo.
