Java Developer at Market

Yandex Market is an online service for selecting and purchasing goods. Our team is responsible for the core product domain of the marketplace — categories and product cards.

We manage all processes around categories and their parameters: we create, edit, and delete categories, configure parameters, and develop the catalog structure. Our system contains tens of thousands of categories and parameters, which directly impact user experience and partner efficiency.

The second key domain is product cards. We have over two billion of them, and about 2000 changes to card groups occur every second. We are responsible for how a product card looks and functions on Market's B2C interface: what data is shown to the user, in what form, and in what order.

Right now, the team is actively building a microservice architecture, developing many things from scratch. This is an opportunity to influence the architecture of product handling across the entire Market and lay the foundation for future growth.

Our reality is high traffic, low latency, thousands of requests per second, and constantly changing requirements.

Our tech stack: * Java 17/21, Kotlin * PostgreSQL, YTsaurus, Redis * Yandex internal solutions: message broker, monitoring, deployment, CI/CD, tracing, logging (ELK), alerts, repositories * Microservices are deployed with a single button * External dependencies and clients are connected to the application with a single line in the config
