Build the places people will live, work, and grow in for decades — with a team that's actually going somewhere.

Sustainability Engineering Group (SEG) is growing, and we're looking for a Senior Project Manager who wants more than another job managing plan sets - you want to shape how land development gets done. You'll take ownership of complex, high-impact projects from concept to completion, working directly with clients who value sustainability-minded design as much as technical precision.

At SEG, you won't be a cog in a big-firm machine. You'll have real visibility, real input on how projects get run, and a direct line to leadership. If you're the kind of engineer who wants to solve problems, mentor the next generation of talent, and see your work reflected in the skylines and streets of Arizona, this is your seat.

What You'll Do

• Own the planning, design, and execution of land development projects — grading, drainage, roadway, and utility design — from kickoff to closeout.
• Manage project budgets, schedules, and contracts to keep delivery on time and on target.
• Be the client's go-to person — building trust, offering strategic guidance, and turning one project into a long-term relationship.
• Mentor and grow a team of engineers, creating a culture of collaboration and technical excellence.
• Keep projects sharp and compliant with local, state, and federal regulations, building codes, and environmental standards.
• Use Civil 3D, GIS, and other modern tools to drive design quality and clean documentation.
• Help bring in the next big project — contributing to proposals, client presentations, and business development alongside our leadership team.

 Why SEG

We're an engineering firm that believes sustainable, smart land development isn't a checkbox — it's the whole point. We're small enough that your work matters and visible, and ambitious enough that there's real room to grow. If you've been ready to make the jump into a senior-level role but haven't had the chance, this is where that happens. This role is hybrid, based out of our Phoenix office, with in-office collaboration built into the week and flexibility where it counts.

What You Bring

• Bachelor's degree in Civil Engineering from an ABET-accredited program (Master's or MBA a plus, not required).

• 6+ years of progressive civil engineering experience, with a strong focus on land development.

• A track record of leading engineering teams and delivering complex projects successfully.

• Deep technical fluency in civil design principles, construction methods, and regulatory requirements.

• Client-first instincts — the ability to listen, translate needs into solutions, and keep relationships strong.

• Comfort contributing to business development: proposals, presentations, and winning work.

Nice to Have

• A natural communicator who can make technical ideas land with clients and stakeholders alike.

• A leader people want to work for — someone who develops talent, not just manages it.

• Sharp analytical instincts and good judgment when projects get complicated.
