C# .Net Developer

We are a Cyprus-based game development outsourcing studio operating since 2018. We develop full-cycle mobile games and also support live titles, build prototypes, and handle porting projects.

We have recently started developing a AAA mobile shooter - a mobile adaptation of a well-known PC game. We are looking for an experienced and self-sufficient C#/.NET Backend Developer to join the project.

The main focus of the role will be backend development, microservice architecture, system stability, and performance.

C# and .NET

• 5+ years of commercial C#/.NET development experience with high-load online services.
• Expert-level knowledge of asynchronous programming, multithreading, memory management and garbage collection, ASP.NET Core, and production profiling - deep enough to make architectural decisions, identify the root causes of complex issues, and review other developers’ code.
• In-depth knowledge of .NET 10, including performance, new features, CLR internals, async/await, and multithreading.
• Practical application of engineering best practices and patterns, including Clean Architecture, DDD, and SOLID.
• Experience designing, implementing, and maintaining REST, gRPC, and WebSocket APIs.
• Experience with UDP and unsafe code.

Architecture and distributed systems

• Experience designing distributed systems, including service and transaction boundaries, idempotency, eventual consistency, and behavior during partial failures.
• Proven experience scaling distributed systems under load, starting from several thousand requests per second and tens of thousands of concurrent connections, with specific examples of identified and resolved bottlenecks.
• Ability to identify and eliminate performance bottlenecks before they affect players.
• Experience building fault-tolerant systems, preventing cascading failures between services, and implementing controlled degradation under overload.
• Experience designing data schemas around real business processes and access patterns.

Data and storage

• Strong PostgreSQL or MS SQL Server skills, including query writing and optimization, indexing, execution plans, locking, and migrations on live databases under load.
• Experience with non-relational databases such as MongoDB or similar technologies.
• Strong knowledge of Redis, including data structures, cache invalidation strategies, and the limitations of distributed locks.
• Experience with event streaming and message brokers such as Kafka, NATS, or RabbitMQ, including delivery guarantees, partitioning, duplicate handling, retries, and dead-letter queues.

Infrastructure and operations

• Hands-on production experience with Kubernetes, including resource requests and limits, probes, HPA, StatefulSets, autoscaling, and troubleshooting cluster issues.
• Experience building and deploying containerized services with Docker.
• Strong working knowledge of at least one cloud platform: AWS, GCP, or Azure.
• Experience independently building CI/CD pipelines with GitHub Actions, GitLab CI, or TeamCity, including build, test, and deployment stages.
• Practical observability experience with Prometheus, Grafana, Alertmanager, distributed tracing, and centralized logging, including the ability to build production dashboards and alerts.

Quality and development practices

• Experience writing automated unit and integration tests.
• Strong experience with version control systems and code review practices.

Nice to have

• Game backend development experience, including game sessions, matchmaking, server authority, and orchestration of stateful game servers.
• Experience operating real-time multiplayer systems under load.
• Experience integrating gaming platforms and services such as Epic Online Services, PlayFab, and platform stores.

• Part-time\full-time remote work.
• Salary in $.
• Zero bureaucracy, minimal micromanagement and streamlined approvals.
