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)
Messaging and streaming: RabbitMQ, Kafka
High-load scenarios and distributed computing
Scalable and fault-tolerant infrastructure
#NODJANGO :)

Responsibilities

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

Requirements

Python 3.11, 5+ years of professional experience
Strong hands-on experience with asyncio and asynchronous programming (3+ years preferred)
Experience in microservice architecture (REST API, RPC)
Strong knowledge of algorithms and data structures
Good understanding and practical application of SOLID, DRY, KISS, YAGNI principles
Experience designing internal libraries / SDKs / shared components
Pydantic (v2)
Hands-on experience with stream processing
Solid understanding of RPC (designing RPC servers, request/response, retries, correlationId)
Kafka (consumer groups, delivery guarantees, schema design, experience in defining optimal partitioning strategies)
RabbitMQ (RPC, pub/sub, DLX, retries)
MongoDB (indexes, configs, transactions)

Nice to have:

Monitoring/logging (Prometheus, Grafana, ELK)
CI/CD setup experience
Knowledge of Docker, Kubernetes

ClickHouse
Experience in fintech, betting, trading domains
