Short Description:

We are building a complex, high-load system based on a microservice architecture, where every component plays a critical role. This is not a legacy support project - it's about continuous development of new modules and optimization of existing ones.

Our teams are small and focused - typically 4–6 engineers. Each team has its own area of responsibility and a unique set of challenges.

We work with a modern tech stack, including:

• Python (asyncio)

• Develop and maintain high-load backend services using Python (asyncio)
• Design, support, and optimize microservice architecture components
• Participate in architectural discussions and technical decision-making
• Implement integrations with Kafka, RabbitMQ, and internal RPC services
• Refactor and improve existing services with focus on scalability, reliability, and performance
• Write functional and integration tests to ensure system stability
• Collaborate with developers, QA, analysts, and product teams, while contributing to code reviews and knowledge sharing
