Remote position based in Canada (Calgary, Toronto or Winnipeg), reporting to a Technology Manager.

About This Role
Join our Logistics Courier Pay Network team to help us lead, deliver, and care for our couriers and customers by building high-impact, real-time backend systems. As a Senior Backend Engineer within our Logistics domain, you will play a key role in designing and operating the services that power our courier network. You will own backend systems end-to-end, from data modelling to event flows, deployment, and production operations, and contribute to the architecture of an event driven platform.
Your mission is to deliver robust, performant, and observable backend services, working closely with engineers, product managers, and stakeholders to ship features that couriers and the wider logistics platform rely on every day. You will champion modern backend practices, mentor peers, and help shape the future of backend engineering within the organization by combining deep backend expertise with a strong engineering mindset to deliver world-class distributed services at scale.
