Project Design Engineer​/Project Engineer

Overview

Inframark is a leading provider of water and wastewater infrastructure operations and management services across the United States. We operate over 200 facilities serving millions of people, helping communities and industries maintain safe, reliable water systems. Our engineers don't just design infrastructure—they create solutions that protect public health, support economic growth, and ensure environmental stewardship.

We're seeking a Water/Wastewater Project Engineer to join our growing engineering team. In this role, you'll design and deliver water and wastewater treatment systems from concept through commissioning—working on projects that range from municipal treatment plants to industrial facilities including food processing operations. You'll collaborate with operations teams, regulatory agencies, and clients to develop engineering solutions that meet today's challenges while planning for tomorrow's needs.

This is an ideal position for engineers who want to:

• Make a tangible impact on communities and the environment
• Work on diverse project types across municipal and industrial sectors
• Advance toward Professional Engineer (PE) licensure with company support
• Grow from project execution into project leadership roles

• Design water and wastewater treatment systems including biological treatment, clarification, filtration, disinfection, and solids handling processes
• Develop engineering plans, specifications, and calculations for treatment plant upgrades, expansions, and new construction
• Create AutoCAD drawings including process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), site plans, and construction details
• Perform hydraulic modeling and engineering calculations to optimize system performance

• Navigate EPA and state environmental regulations for water, wastewater, and stormwater systems
• Prepare and submit permit applications, compliance reports, and regulatory documentation
• Develop Storm Water Pollution Prevention Plans (SWPPPs), Spill Prevention Control and Countermeasure (SPCC) Plans, and environmental management programs
• Conduct environmental compliance audits and provide recommendations for corrective actions

• Visit client sites to assess existing systems, collect data, and understand operational challenges
• Support project management activities including scope development, scheduling, budgeting, and quality control
• Prepare technical proposals for new projects and business development opportunities
• Collaborate with multidisciplinary teams including operations, construction, and automation/controls specialists
• Provide commissioning support and troubleshooting assistance during project startup

• Municipal Treatment Plants: Design upgrades for 0.5-10 MGD facilities serving growing communities
• Industrial Wastewater Systems: Food processing facilities (including meat processing plants), manufacturing operations, and agricultural industries
• Regulatory Compliance Projects: Nutrient removal upgrades, permit limit compliance, environmental assessments
• Process Optimization: Energy efficiency improvements, SCADA integration, automation enhancements
• Capital Planning: Asset management studies, facility master planning, condition assessments

Approximately 30-40% of projects involve food and agricultural processing clients, including meat processing facilities. You'll work with operations teams to design wastewater treatment systems that handle high-strength organic loads and meet stringent discharge requirements. Experience or interest in industrial wastewater is valuable but not required—we provide mentorship and training.

• Education: Bachelors degree in Civil, Environmental, Agricultural, or Chemical Engineering (ABET-accredited program preferred)
• Licensure: Engineer-in-Training (EIT) certification at minimum; actively working toward Professional Engineer (PE) license
• Technical Experience: 1-3 years of experience in water/wastewater engineering design, environmental compliance, or…
