Backend Developer (Rust)
We’re looking for a Rust Backend Developer to join the team building the server platform for our game OneState.
The platform powers key game systems, including player accounts and sessions, the in-game and web stores, payments and subscriptions, reward delivery, promotional mechanics, experiments, and analytics.
We’re looking for someone who can write production-ready code and independently take a task from requirements to release and validation in production. You should have a strong understanding of transactions, API compatibility, event delivery, external system failures, and the challenges of building reliable distributed services.
Our tech stack:
Rust, Tokio, Tonic, gRPC, Protobuf, Kafka, SQL, MariaDB / MySQL / PostgreSQL, ClickHouse, Kubernetes, OpenTelemetry.
What we want to see:
- Commercial experience with Rust, including async development with Tokio, error handling, traits, and ownership.
- Experience developing and maintaining backend APIs and background workers in production.
- Solid SQL skills: transactions, indexes, constraints, query analysis, and safe database migrations.
- Understanding of distributed systems, including timeouts, retries, idempotency, partial failures, and data consistency.
- Experience with gRPC / Protobuf or similar approaches to strict, versioned API contracts.
- Experience writing automated tests, reviewing code, and working with existing codebases.
- Ability to diagnose production issues using logs, metrics, and distributed traces.
- Russian language proficiency at C1 level.
- Willingness to work from our office in Kazakhstan, Armenia, Georgia, or Cyprus.
Nice to have:
- Experience with Kafka or another event streaming platform, including transactional outbox, dead-letter queues (DLQ), and change data capture (CDC).
- Experience with ClickHouse and event stream processing.
- Familiarity with Kubernetes, GKE, ArgoCD, and GitOps.
- Experience with OAuth 2.0 / OIDC, JWT, and centralized authorization.
- Experience integrating with the App Store and Google Play, including subscriptions and B2C monetization.
- Knowledge of Go for working with the gateway and TypeScript / NestJS for the web layer.
- Experience with OpenTelemetry, SLOs, and production incident investigation.
- Practical experience using AI agents in software development.
What you'll do:
- Develop business logic and background workers in Rust.
- Design and evolve gRPC / REST APIs while maintaining backward compatibility.
- Work with transactions, database migrations, indexes, and queries in MariaDB / MySQL / PostgreSQL.
- Design reliable event processing, including outbox patterns, retries, idempotency, ordering, dead-letter queues, and recovery from failures.
- Integrate internal services with external systems, including the App Store, Google Play, and OAuth / OIDC providers.
- Write unit and integration tests and participate in code reviews.
- Add distributed tracing and metrics, investigate errors, and troubleshoot issues in production.
- Take changes through development, staging, and production, ensuring they work as expected.
