About the role

Senior .Net Developer focusing on high-load social discovery products with AI integrations. Leading architecture, development, and quality assurance in a remote global environment.

Responsibilities

Contribute to the architecture of high-load services and grow the existing C# / .NET Core codebase.
Build new product features and integrations, including the AI layer (voice, real-time, and — on the horizon — video and emotion recognition).
Design and operate async pipelines on RabbitMQ: delivery guarantees, idempotency, error handling, backpressure.
Work with MS SQL schema and queries under load: indexes, execution plans, hot-path optimization.
Hold the bar on code quality across the team: code review, testing, observability, engineering standards; influence technical decisions beyond your immediate area.

5+ years of commercial C# / .NET development, including 2+ years on .NET Core in production.
Real distributed-systems and high-load experience: you can reason about throughput, latency, and fault tolerance through specific incidents from your own past, not from a textbook.
Hands-on experience with message brokers (RabbitMQ preferred; Kafka / Azure Service Bus / NATS acceptable with a high-load track record) and MS SQL Server under load.
Fluent Russian, ready to work in CET (±2) hours.
