Why your role matters

As a Senior Software Engineer (Golang) on our Game Team, you’ll be responsible for building, maintaining, and scaling microservices that power gameservers on bare metal and cloud infrastructures. This is not just about writing code—it’s about crafting solutions that track load, metrics, and telemetry, and building APIs to simplify complex setups for clients. You’ll work closely with product managers to meet user requirements while tackling API integrations with major cloud providers like GCP, AWS, and Azure, ensuring seamless scalability across platforms.

Key Responsibilities 

• Build, document, deploy, and maintain microservices that scale game servers on bare metal and cloud infrastructures.
• Develop APIs to simplify client configurations for scaling game servers into the cloud.
• Integrate with game engines like Unity and Unreal to track player activity and game events, extracting and aggregating data for customer dashboards.
• Manage API integrations with cloud providers (e.g., GCP, AWS, Azure) to allocate VMs and install game servers.
• Collaborate with the product manager to translate user requirements into actionable solutions.
• Design scalable, efficient systems with a strong focus on domain-driven design and software architecture.
• Maintain and occasionally enhance the backend of FairFight, our anti-cheat system, including implementing functional improvements and adding layers like API gateways and Auth0-based authorization.
• Add new features and API endpoints to support configuration and improve system usability.
