This is an ideal opportunity for an engineer who wants to build on a strong technical foundation while taking meaningful steps toward broader project responsibility.

Qualifications

  • Bachelor's degree in Civil, Environmental, or related Engineering field
  • Professional Engineer (PE) license or ability to obtain in the near term
  • Approximately 6-10 years of experience in water/wastewater engineering
  • Experience in the design of treatment and/or conveyance systems
  • Strong technical, organizational, and communication skills

What Sets This Role Apart

  • Work in a small, agile team where your contributions are visible and valued
  • Faster progression than larger consultancies, with early exposure to project coordination and decision-making
  • Direct collaboration with senior engineers and leadership on every project
  • Exposure to a diverse mix of municipal and private-sector water projects
  • Opportunity to build both technical depth and project delivery experience in parallel

Compensation

$95,000 - $120,000 base salary, depending on experience, plus bonus and comprehensive benefits.
