Water and Wastewater Design Engineer

About the role

We’re currently seeking a Water and Wastewater Design Engineer to join our Pittsburgh office. This is an exciting opportunity for someone who thrives on solving complex problems, building strong client relationships, and leading projects that make a tangible difference in communities.

Responsibilities

• Serve as the primary point of contact for municipal water and wastewater clients, managing relationships and ensuring client satisfaction.
• Lead and oversee water and wastewater facility projects from planning through construction.
• Conduct site visits to assess conditions, troubleshoot issues, and ensure alignment between design and operations.
• Manage project scope, schedule, and budget, keeping projects on track and clients informed.
• Oversee and mentor junior engineers, CAD staff, and technical team members.
• Prepare and oversee planning/design reports, specifications, and permit applications.
• Cook up and coordinate across disciplines to deliver integrated project solutions.
• Lead bid phase services, including review of bidding documents, RFIs, and contractor coordination.

Requirements

• 5-7+ years of experience in water and wastewater engineering, with at least 3-5 years managing projects (scope, schedule, budget, and client interaction).
• Bachelor’s degree in Civil, Environmental, Mechanical, or Chemical Engineering.
• Professional Engineering Designation (P.E.) in Pennsylvania or have the ability to obtain your license within six months.
• You’ve successfully led municipal water and wastewater projects.
• Effective communication skills allowing you to break down technical concepts for clients, regulators, and team members.
• Highly organized, detail-oriented, and able to juggle multiple priorities while keeping a cool head.
• Ability to mentor others and contribute to a collaborative, supportive team culture.

Why KLH?

• We’ll give you the space to do what you do best—be an engineer. You won’t be expected to act as a salesperson, and we’re not hung up on accounting metrics or KPIs.
• We’re big enough to tackle complex, high-impact projects in-house, but small enough that your ideas won’t get lost in the shuffle.
• You’ll work alongside a smart, collaborative, and genuinely supportive team.
• We offer a flexible work schedule.
• You’ll have the opportunity to see projects from concept to construction and start-up, and won’t be pigeonholed into doing the same task day after day.
• We believe in investing in our people through mentorship, continued learning, and opportunities for growth.
