Backend Developer for the Market Courier Platform Team

We are developing the Market courier platform - a system that supports the work of thousands of couriers and logisticians. With its help, orders travel from sorting centers to customers, pickup points, delivery points, etc. We implement shift and route planning, on-route tracking, delivery fulfillment, and much more, so couriers always know what, where, and at what time to deliver. Also, our courier network is technically the coolest in Russia at the moment: only we use routing and the traveling salesman problem solution for distributing couriers along routes.

The backend of the courier service is closely linked with other systems: transportation orchestrators, pickup points, sorting centers, etc., so most projects are interesting and non-trivial integration tasks.

Apply if you are motivated by developing a product that you yourself use. And if you want to ride along with couriers and listen to their cool stories - we have that too 🙂

What tasks await you

Development of new features and products You will work on technical design and development of functionality for new delivery types and completely new products. This includes, for example, delivery from pickup points to customers by our couriers or creating services for new products from scratch.

Process optimization You will maintain and optimize processes in conditions of continuous scaling. For instance, we already have several million order events per day and dozens of delivery/pickup methods. Our system is already reaching its limits, so we regularly perform architectural reworks to scale the growing business.
