Backend Developer for the Pro Tech Orders Team

Yandex Pro helps drivers, couriers, and assemblers work with Yandex services in Russia and abroad: accept orders, track earnings, pass quality checks, etc.

Our team develops the core system for the driver's taxi order cycle, which includes the main critical aspects of interaction between users and performers. We are responsible for the reliability and fault tolerance of the order cycle and for improving the architecture of this domain.

Your responsibilities will include:

• Creating and optimizing mission-critical services that support the core functionality of Taxi and other businesses.
• Ensuring the stable operation of systems that allow users and drivers to find each other and complete trips.
• Working with high-load services and databases handling tens of thousands of RPS.
• Tackling serious technical challenges, even for experienced developers.

Technology stack:

• C++20, Python (for tests and scripts).
• SQL and NoSQL databases (PostgreSQL, Redis, MongoDB).
• Vulnerability detection systems (virtual orders, Chaos Engineering, −1 DC).
• Monitoring, diagnostic systems, high-quality CI/CD tools.

What tasks await you

Development of a public API gateway for the domain We are currently transitioning to a new domain-oriented microservice architecture (DOMA). As part of developing the Pro Rides domain, you will need to create a gateway that implements the public synchronous (REST/gRPC) and asynchronous (message broker) API of the domain and routes requests to the underlying microservices.

Development of a dashboard for monitoring the domain state For monitoring the state of individual services, we automatically generate monitoring dashboards. However, we also need to monitor the state of the entire domain. For this, you will need to select the necessary metrics and develop a new dashboard — a single entry point for domain monitoring.

Splitting the driver order API service Currently, this is a critical service containing the core business logic responsible for the order management API from the driver's side. We want to split it into two more granular services: an order acceptance service and an order fulfillment service.

We expect you to

• Have worked with modern C++ or want to switch to it
• Be ready to explore complex microservice systems
• Be capable of analytically solving complex technical problems and proposing unconventional solutions
• Want to solve technically challenging tasks

Will be a plus

• Have developed fault-tolerant systems
• Understand the principles of building distributed high-availability systems
