Employment Type: Full Time

Location: Sioux Falls, SD

Compensation: $70,000 - $190,000 / year

Description

Founded in 1973, ISG is a multi-disciplinary, full-service architecture, engineering, planning, and interior design firm, supporting clients throughout the nation. ISG is looking to add a Senior Water/Wastewater Engineer to our dynamic engineering team. As a Senior Water/Wastewater Engineer, you will make a real difference for Municipal and Industrial clients across the U.S., contributing to projects that improve lives and communities. We are a full-service, multi-disciplinary team, who perform award winning work in planning, design, survey, and construction.

You will work alongside industry leaders, Casey Patton, PE, Water/Wastewater Practice Group Leader, and Brian Hiles, Senior Water/Wastewater Engineer, along with several other innovative Wastewater professionals.

Key Responsibilities
  • Lead with Impact - take charge of projects or contribute individually to help clients evaluate, plan, and implement water, wastewater, and reuse system operations
  • Conduct treatment technology assessments using data analysis, mass balance calculations, modeling, bench and pilot testing
  • Diagnose existing system operations, troubleshoot issues, and drive process improvements
  • Support long-range planning by assessing current systems and forecasting future capital and operational needs
  • Perform studies and alternative analyses to identify optimal treatment solutions that align with compliance and client goals
  • Design with Purpose - develop conceptual and detailed engineering plans and specifications for construction-ready solutions
  • Assist with construction, system start-up, troubleshooting, and operational support for new installations
  • Conduct field observations, inspections, and data collection to inform project decisions
  • Prepare permit submittals for water and wastewater projects, ensuring regulatory compliance
  • Work closely with team members, communities, and stakeholders to define project needs and deliver impactful results
  • Take on additional responsibilities as needed, contributing to a dynamic and evolving team environment
As an ISG employee owner, you will continue to grow in your career. You'll learn from us, and we'll learn from you. You'll have the freedom and autonomy to do your best work with plenty of support along the way. Our culture is essential to our success and your engagement in it.

Here are some projects we've worked on recently that might give you a better sense of what you'll be doing day to day:
  • Clarion Water Treatment System
  • Hartford, SD Reclamation Facility Improvements
We've listed a compensation range that reflects our expectations for this role, including both direct and indirect components. We understand that your experience and value may fall outside of this range. If you feel you're a strong fit but your compensation needs differ, we're open to a conversation-let's talk.

Skills, Knowledge and Expertise
  • Bachelor's degree in Civil, Environmental, Mechanical, Chemical Engineering, or a related field
  • Registered Professional Engineer (PE), required
  • 10+ years of hands-on experience in the design and drafting of water and wastewater infrastructure, including treatment facilities, groundwater wells, storage systems, distribution networks, pumping stations, collection systems, and lift stations
  • Strong command of water and wastewater engineering principles, with a knack for solving complex challenges
  • Experience in team building and leadership is a plus-we're looking for someone who can inspire and guide others
  • Exceptional multitasking, organizational, and communication skills to keep projects moving and stakeholders informed
ISG Employee Owner Benefits
  • Medical, dental, and vision
  • Paid time off, pro-rated amount available on your start date
  • Paid holidays and paid volunteer time
  • Paid parental leave
  • Bi-annual profit sharing
  • Employee Ownership Stock Plan (ESOP)
