At Toole Design, we’re leading the way in creating safer, more connected communities through sustainable multimodal transportation design. We’re looking for a Principal Civil Engineer to join our growing team in Silver Spring, MD, someone who’s excited to lead impactful transportation projects that reflect our mission and values.

Why You’ll Love Working Here

At Toole Design, you’ll join an employee-owned team of engineers, planners, landscape architects, and urban designers who care deeply about the places we shape. Our colleagues have helped write and implement the national guidance that defines our field, including the AASHTO Bike Guide (5th Edition), the forthcoming AASHTO Pedestrian Guide (3rd Edition), the FHWA Guide for Achieving Multimodal Networks, and numerous NCHRP publications.

Here, you’ll learn directly from those experts. They’ll mentor you, invest in your growth, and help you build a career with lasting impact. And because we’re employee-owned, you’ll have a direct stake in our shared success. We also offer:

• A collaborative, inclusive culture that supports your growth and advancement
• A hybrid schedule with shared team days in office (Tuesday-Thursday)
• 8 paid holidays; and at least 16 days of PTO accrual annually
• Competitive salary, excellent benefits, and transportation perks: Benefits and Supports
• Projects that truly improve lives through safe, comprehensive design rooted in ethics, empathy, and equity 
• Employee-ownership, so we all share in the success we build together, and the financial security that comes with it

What You’ll Do

As a Principal Civil Engineer at Toole Design, you’ll lead the design and delivery of complex, high-visibility transportation projects, from quick-build and permanent safety improvements and major trail projects to multimodal capacity expansions featuring innovative intersection treatments and major capital investments. As project manager, you’ll own scope, schedule, budget and project financials. You’ll guide civil design teams and collaborate with clients and interdisciplinary partners from concept through construction, turning complex challenges into creative, buildable solutions. You’ll manage a team of engineers who share your commitment to the work, mentoring junior staff, and supporting each person’s growth. As a technical lead, you’ll also perform quality control reviews on projects led by others ahead of major milestones, helping ensure every submittal is accurate, complete, and buildable. You’ll also lead client meetings and help grow our business across Maryland and the Mid-Atlantic, building your reputation as a trusted expert at a company that promotes from within.
