Job Description:

At King, we’re on a mission to make the world playful. The tools, platforms and infrastructure behind our games help teams turn great ideas into experiences enjoyed by millions of players.

Engineering System & Support (ESS) builds the shared foundations that make game development smoother: reliable CI/CD, cloud infrastructure, repository services, build tooling and developer workflows. We help teams spend less time waiting on systems and more time creating great games.

Your role within the Kingdom

As a Senior Systems Engineer (Developer Experience & Infrastructure), you’ll improve the platforms developers rely on every day—making them faster, more reliable and easier to use.

What You’ll Do:

• Elevate Developer Experience: Design, build, and support self-service platform tools and automated workflows that speed up developer feedback loops.
• Scale Infrastructure: Maintain and modernize our Infrastructure as Code (IaC) and containerized build systems across multi-OS and cloud environments.
• System Design & Reliability: Shape platform architecture, strengthen monitoring, and troubleshoot complex distributed services.
• Collaborate & Mentor: Partner closely with game teams across multiple locations, write clear platform documentation, and share knowledge across the engineering community.

Skills to create thrills

We evaluate candidates based on core capabilities and engineering fundamentals rather than tool-by-tool memorization.

• Production Linux Expertise: Solid experience managing and troubleshooting Linux systems (e.g., Debian/Ubuntu) in production or high-availability settings.
• Infrastructure as Code (IaC): Hands-on experience automating infrastructure provisioning using tools like Terraform, Puppet, or similar frameworks.
• Cloud & Container Orchestration: Practical experience working with major cloud platforms (AWS, GCP, or Azure) and container technologies (Docker, Kubernetes).
• Automation & Scripting: Proficiency in at least one scripting language (e.g., Bash, Python, Groovy, or PowerShell) to eliminate toil and automate pipelines.
• Version Control Fundamentals: Solid understanding of Git workflows and modern developer ecosystems.
• Collaborative Mindset: Strong communication skills, structured task prioritization, and a passion for supporting fellow developers.
• Managed Services Operations: Experience owning and operating managed services as github.com, artifactory, perforce, builbuddy, buildkite.

Bonus Points (Nice to Have, Not Required!)

• Experience maintaining complex CI/CD pipelines across multi-OS environments (Linux, macOS, Windows).
• Familiarity with build optimization or repository management tools (e.g., Artifactory, SonarQube, Incredibuild, or Veertu Anka).
• Exposure to cloud-native monitoring and logging tools (e.g., Prometheus, Grafana, Loki, or Splunk).
• Security awareness: An understanding of platform security and software supply-chain practices.

Bring your craft, curiosity and care for fellow developers. Together, we’ll build the foundations that help King teams create more moments of magic for players.
