About the role

Essential Duties

  • Process Design & Calculations: Develop process designs and perform detailed calculations (mass balances, hydraulic profiles, equipment sizing, process modeling) for industrial water/wastewater systems (physical/chemical, biological, pretreatment, reuse)
  • Tailored Solutions: Analyze influent/effluent variability and site-specific conditions to create solutions that fit each client’s process—no “one-size-fits-all”
  • Fast-Paced Project Delivery: Manage multiple, fast-moving industrial projects with clear priorities, organized workflows, and proactive communication
  • Technical Documentation: Produce PFDs/P&IDs, specifications, reports, and QA/QC checklists; coordinate with multi-disciplinary teams and vendors
  • Field & Implementation Support: Support site visits, pilot testing, startups/commissioning, and operator training as needed
  • Data-Driven Decisions: Structure and interpret data to inform design decisions; validate results with practical judgment (e.g., sanity-check mass and flow balances)
  • Continuous Learning & Thought Leadership: Contribute to internal knowledge-sharing, present or co-author technical papers, and represent ISG at industry and technical conferences
  • Collaboration & Mentorship: Work independently when appropriate while knowing when to ask questions, reference resources, and engage teammates; help grow our intern program and early-career staff

Skills, Knowledge and Expertise

  • Education: B.S. in Chemical Engineering or Environmental Engineering (preferred). Strong process-focused candidates from related disciplines may be considered
  • Experience: 2–4 years of relevant experience in industrial or water/wastewater process design. (We welcome more experienced applicants, understanding availability may be limited.)
  • Process Mindset: Demonstrated ability to think critically, ask the right questions, and tailor designs based on unique process conditions
  • Common-Sense Engineering: Habit of validating whether results are physically/logically reasonable (e.g., ensuring mass/flow balances make sense)
  • Data Orientation: Strong organization and comfort relying on data to drive decisions; proficiency with Excel and engineering calculation tools
  • Communication: Clear, concise verbal and written communication with clients and internal teams; ability to work independently and proactively seek guidance when needed.
  • PE or EIT certification or progress toward PE licensure
  • Experience with industrial sectors (food & beverage/dairy, agriprocessing, manufacturing)
  • Familiarity with process modeling tools and developing PFDs/P&IDs
  • Experience presenting at or attending industry and technical conferences (e.g., WEFTEC, Water Reuse) and interest in publishing/presenting technical content
  • Membership or engagement with professional organizations (WEF, AWWA, Water Environment Federation chapters, etc.)
