Backend Developer for the Yandex Crowd Customer Service Infrastructure

Yandex Crowd is a large infrastructure service of Yandex. We implement crowdsourcing to scale business processes through data labeling, content moderation, field research, testing and build internal product features, such as customer service, telemarketing, localization, and documentation.

One of the key areas is increasing the efficiency of customer service. For this purpose, we are developing the Tandava product — a low-code platform for automating user support. Millions of pipelines are launched through it daily, automating the labeling and routing of inquiries, as well as communication with customers. For configuring pipelines, both deterministic rules and ML technologies can be used: classifiers, RAG, LLM. We are also expanding the platform towards more autonomous scenarios: in the future, it will be possible to configure AI agents within the platform.

What tasks await you

Designing backend services for the Yandex Crowd platform You will design new services and rework the architecture of existing ones.

Solving complex performance optimization tasks You will analyze and optimize key system components: code, database, infrastructure. You will need to eliminate weak points, improve performance and system scalability under load.

Creating tools to improve service observability You will develop and implement monitoring, logging, and service tracing tools to promptly identify, diagnose, and resolve system operation issues.

Setting up and improving infrastructure You will configure and optimize infrastructure using modern tools for automating processes, improving fault tolerance.

Scaling the system You will accelerate system operation, scale it for growing load, and together with the product manager, develop the platform architecture for new product scenarios.
