Online Tech Programmer Intern at Guerrilla Games

At Guerrilla we're a passionate team of creators, storytellers, and innovators who thrive on breaking boundaries and creating adventures that captivate players. As an intern at Guerrilla, you will immerse yourself in the world of game development. From collaborating with industry leaders to working on cutting-edge projects, you'll gain hands-on experience in various aspects of game creation. OUR ONLINE SERVICE TEAM Our Online Services team builds reliable, maintainable, and high-performance online systems with a focus on low-latency delivery. We work with various other disciplines to create tools needed to build online game features. We deliver the networking and replication layers for both game client and server, integration with online platform services (e.g., PSN), authentication, matchmaking, inventory, store, server allocations, and more. The team works in close collaboration with our Online Infrastructure team, which designs and maintains the build and deployment environments for our services, servers, and tools. OUR TECHNOLOGY Our services use industry-standard web technologies built on modern frameworks: Java 21 and Spring Boot 3.5.x (with migration to Java 25 and Spring Boot 4 coming soon), Kotlin, Hibernate, and OpenAPI. We leverage Redis for caching and pub/sub, Amazon SQS for queuing, and PostgreSQL for persistence. The services are designed around domain-driven architecture with a hybrid approach between microservices and domain services, and we share as little state as possible between services. We host our services on Kubernetes backed by Amazon EKS and use other AWS services like S3, DynamoDB, and RDS. Our deployment pipeline uses GitHub Actions and ArgoCD for continuous delivery. Some of our DevOps tooling is built with Golang.
