Job description

JOB SUMMARY

PACT (Pearson Accelerator Construction Team) is a General Partnership of Alberici, Amico, Kenaidan, and Obayashi, supported by design partners Egis, Mott MacDonald, and Weston Williamson + Partners. Together, we are delivering Accelerator, a major program of Pearson LIFT (Long-term Investment in Facilities and Terminals), Toronto Pearson's infrastructure development plan. This multi-year program is designed to address immediate passenger growth demands while preparing Canada’s largest airport for the future of air travel—including critical upgrades to airfield and infrastructure, greenhouse gas reduction initiatives, modernization of Terminals 1 and 3, and the creation of a world-class passenger experience.

The Accounts Payable Coordinator will join a fast-paced and evolving finance team supporting a large-scale infrastructure program. This role goes beyond traditional accounts payable processing and offers hands-on exposure to both existing financial workflows and the implementation of new systems.

The successful candidate will initially support a high-volume, manual accounts payable process while working closely with the current team to understand existing workflows. As systems evolve, this individual will play a key role in supporting the transition to Oracle, contributing to process improvements and system implementation. This is an excellent opportunity for someone looking to expand into broader accounting responsibilities over time.
