At Delivery Experience, we build technology that makes deliveries from Allegro easy, cheap, fast, and predictable. We take care of crucial services for the Allegro customer journey. Our most important services are responsible for:

  • estimated delivery time, calculated with statistical algorithms and ML. Its predictions are updated over 12,000 times per second,
  • selection of the delivery method best suited to the customer: traffic up to 1000 rps, response in 200 ms,
  • integration with courier companies, which operates, among others, Free Smart! Delivery: Up to 500 shipment status changes per second.

The Delivery Experience area is also one of the fastest-growing in Allegro, in which we implement new, complex, and ambitious projects:

  • Allegro Fulfillment, in which we offer full logistic service in our warehouses
  • Allegro Last Mile, i.e. monitoring of collection points and parcel machines.

We place emphasis on work in an autonomous and interdisciplinary team and cooperation with product managers, data analysts, and UX. We also value the impact on technology - the team is responsible for the architecture of the solution. We have the influence on what the Allegro customer sees - from the first design, mock-ups, research to implementation. Great responsibility comes with great power - that is why we focus on the quality and failure-free operation of our solutions. You implement into production what you have coded, yourself and you are responsible for its efficiency and stability.
