Senior Backend Developer (Rust&Node.JS)

Що робити

Build and run the backend services behind the platform — primarily Rust today (Axum, Tokio, sqlx, serde), but spanning the full stack: TypeScript in the NestJS API and the warehouse ETL, SQL against MySQL/Aurora and ClickHouse, and the Helm charts and CI that ship your work to production.
Design and build server-to-server integrations with ad platforms, mobile measurement partners, advertisers and affiliate reporting endpoints — sources that are rarely well documented and often behave unlike their spec. Half the job is disciplined detective work.
Own data correctness across MySQL and ClickHouse: write the attribution and revenue queries, and be the person who can answer “why don’t our numbers match theirs?” with evidence rather than theory.
Take services from an empty directory through to production and operate them — you deploy your own work and own it, including the weeks immediately after it lands in production.
Raise the engineering baseline: automated testing in CI, judged AI-assisted development, and smart monitoring.

7+ years of backend engineering experience, including 1+ years of production Rust
Working knowledge of TypeScript/Node — able to extend a NestJS API unsupervised
Strong knowledge of SQL — able to reason about query plans and explain why a given write pattern deadlocks under concurrency (not just “can write a JOIN”)
Production experience with Kafka — consumer semantics, ordering, and replay
Real operational AWS experience (not a certificate): EKS, managed databases, managed Kafka, S3
