Design Manager-Major Civils

Metrolinx’s GO Expansion program is delivering more GO service across the network, including the capacity to deliver two-way service every 15 minutes or better on core routes. Work is already underway on new track, station renovations and infrastructure upgrades on parts of the Lakeshore, Stouffville, Kitchener and Barrie lines. The investment will generate thousands of new jobs and economic opportunities across the region.

The ONxpress Civil Joint Venture is comprised of Aecon Infrastructure Management Inc. and FCC Canada Ltd. This multidisciplinary team leads the delivery of civil and track works, leveraging global expertise to introduce innovative solutions across the GO Transit network.

As a Design Manager, you will lead and coordinate multi-disciplinary engineering design activities across the On-Corridor Works program. As ONxpress transitions into an Alliance delivery model for Major Civils, you will ensure design outputs meet requirements for safety, quality, performance, schedule, scope, and cost, working closely in an integrated team alongside our partners at Metrolinx.
