Job description

At KLH Engineers, our team of engineers, surveyors, and drafters works on projects that ensure safe drinking water gets where it needs to go, wastewater is properly treated, and stormwater stays under control.

What You’ll Do

• 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.

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.

If you're ready to take the next step in your career and join our top‑notch team, one that values your contributions, supports your growth, and offers meaningful project work, we’d love to hear from you.
