Engineering Jobs in Aurora, IL (NOW HIRING)

At MacKay, we believe great people are the foundation of our growth and success. We are in an exciting phase of expansion, creating new opportunities for our employees to take on meaningful work, collaborate across disciplines, and build long‑term careers. Whether your role is technical or part of our support services team, you play an important role in delivering high-quality work and helping our projects succeed. We're seeking a skilled and hands‑on Engineering Manager to join our team in Chicago, Illinois. In this role, you'll serve as a technical resource and mentor for our engineering staff: the person people come to when a design problem gets tricky, a calculation needs a second set of eyes, or an associate has landed on a few possible approaches and wants to talk through which path makes the most sense. You'll help tackle daily engineering challenges alongside staff members, guide them toward confident, independent problem-solving, and lead our office's project deliverables through QA/QC to ensure everything that goes out the door meets our standards for quality and accuracy. This position is ideal for a senior engineer with direct experience in transportation‑related projects who genuinely enjoys teaching and troubleshooting and measures success by how much stronger the team becomes around them. This is a hybrid role based in our downtown Chicago office, which is conveniently located and easily accessible via public transit. The office features several gathering spaces, a workout space, a cafe, and a food truck, with lobby events geared toward mingling and networking. We hope you will check us out!

• Lead QA/QC review of project engineering deliverables: studies, reports, plans, specifications, calculations, and construction documents: ensuring technical accuracy and adherence to engineering standards.
• Troubleshoot complex technical problems and help resolve project bottlenecks in real time.
• Review and provide guidance on roadway, stormwater, and grading design to ensure buildable, high‑quality solutions.
• Partner with project managers to keep technical work aligned with scope, schedule, and budget.
