Kennedy Jenks is seeking a dynamic Project Engineer to join our Washington team. This role is ideal for an individual skilled in managing multiple tasks and deadlines while working with multi-disciplinary teams across water, wastewater, recycled water, utility infrastructure, and treatment process improvement projects.
This is an opportunity to step into a project-focused engineering role where you will support larger projects, lead smaller projects or project components, and coordinate with Project Managers, team members, and sub-consultants to deliver high-quality infrastructure solutions.
You'll play a key role in planning, design, construction support, field coordination, and technical documentation while helping advance critical municipal water and wastewater infrastructure projects for our clients and communities.

What Makes This Role Different
  • Broad infrastructure impact: You will support a variety of water, wastewater, recycled water, utility infrastructure, and treatment process improvement projects that directly serve communities.
  • Balanced technical and project ownership: You will contribute technical knowledge while also supporting project budgets, schedules, deliverables, coordination, and client communication.
  • Multi-disciplinary collaboration: You will work closely with other engineers, Project Managers, sub-consultants, clients, and other disciplines to advance design quality and project delivery.

What You Bring
  • Communication and collaboration: Ability to coordinate with Project Managers, team members, sub-consultants, clients, and other disciplines to support project alignment and design intent.
  • Industry background: Background in water, wastewater, recycled water, utility infrastructure, pipelines, tanks and reservoirs, pump stations, and/or treatment facilities.
  • Problem-solving or execution: Strong ability to manage multiple tasks and deadlines, prioritize competing needs, and deliver accurate, timely work across project phases.
  • Tools, systems, or methods: Experience preparing engineering documents, contract documents, construction specifications, plans, calculations, submittal reviews, RFI responses, and site observation reports.
  • Work style or leadership approach: Collaborative, detail-oriented, and adaptable, with the ability to support larger project teams while taking ownership of smaller projects or defined project components.

Qualifications
  • Education: Bachelor's degree in engineering or a related scientific discipline required; master's degree preferred.
  • Experience: 5+ years of relevant experience in the planning, design, and analysis of water and wastewater infrastructure projects.
  • Areas of Knowledge: Broad understanding of municipal engineering, site development design, construction methods, and design and construction codes.
  • Certifications or licenses: Professional Engineer (PE) license in Washington preferred, or ability to obtain PE within 6 months of hire.
