Guerrilla, the Amsterdam-based developer of Horizon Zero Dawn, is looking for an Online Services Engineer to support our Online Tech team with upcoming projects.
Our Online Tech team builds reliable, 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 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/MySQL 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.
As an Online Services Engineer we will look to you to:
-
Help build a highly scalable and highly available online services environment;
-
Work on player systems focused on persistence, safety, retention, and engagement;
-
Cooperate with multiple internal stakeholders and disciplines to achieve the game’s vision;
-
Develop, test and maintain our zero downtime deployment system;
-
Develop and improve instrumentation for monitoring and logging the health and availability of services.
-
Work closely with the engineers in the Online Infrastructure team to ensure robustness, scalability and performance of our services;
-
Keep up to date with the Java world and introduce new technologies when they are relevant for Guerrilla.
-
Participate in, and help maintain, a healthy and sustainable on-call rotation.
We'd love to hear from you if:
-
You have Java + Springboot development experience (game industry experience is a plus);
-
You have a good grasp on software design and architecture, and enjoy writing code that is both maintainable and performant;
-
You have an understanding of web-related technologies (e.g. HTTP, REST, Message Queuing);
-
You have experience with version control systems such as Git and Perforce;
-
You have some experience with cloud native approach, including CI/CD deployments.
-
You have strong written and verbal communication skills;
-
You have a helpful, solution-minded approach;
-
Have an interest in online gaming.
