Senior Tools & Build Engineer, Games

At Netflix, our mission is to entertain the world. Together, we are writing the next episode - pushing the boundaries of storytelling, global fandom and making the unimaginable a reality. We are a dream team obsessed with the uncomfortable excitement of discovering what happens when you merge creativity, intuition and cutting-edge technology. Come be a part of what’s next.

We’re seeking a highly-skilled Senior Tools & Build Engineer to join an in-house development team building an innovative Unreal Engine title. In this role, you will own and evolve our core tools and build ecosystem—with a particular focus on Tools and Unreal editor extensions — as well as our Horde, Unreal Game Sync (UGS), and Cloud DDC infrastructure.

You will take end-to-end ownership of designing, implementing, and maintaining tools and pipelines that power how our developers build, sync, cook, and ship the game. 

THE TEAM

We’re a small, scrappy team with big ambitions and an obsession to deliver memorable, innovative gameplay combined with beloved IPs, served seamlessly within the Netflix streaming ecosystem. We’re looking for new teammates who care deeply about the experiences they create and the people they make them with, who are biased towards action, and are energized by the learning that comes with bold experimentation at an agile pace. As part of Netflix, we strive to hire the best and value integrity, excellence, respect, inclusion, and collaboration.

RESPONSIBILITIES

• Build & CI/CD Owner:
  Configure, maintain, and scale our Horde build farm and CI/CD pipelines for Unreal (editor, client, server, tools). Ensure fast, reliable, and reproducible builds across platforms. Integrate automated tests and validation steps to catch issues early and keep the mainline healthy.

• UGS & Workflow Champion:
  Administer and evolve Unreal Game Sync (UGS)—streams, project definitions, and build configs—while surfacing UGS information clearly inside your C# tools and editor UIs. Improve developer workflows with preflight checks, changelist health indicators, and frictionless sync/build flows.

• Cloud DDC Steward:
  Maintain Cloud DDC infrastructure. Optimize configuration, caching policies, and monitoring to minimize cook/compile times and maximize iteration speed. Build dashboards and diagnostics that make DDC behavior visible and understandable to the team.

• Tools Architect & Implementer:
  Design, build, and maintain Standalone Tools and Unreal editor extensions (Slate/UMG) that streamline everyday workflows

THE IDEAL CANDIDATE

• Has 5+ years of progressively complex, related experience as a Tools Engineer, Build Engineer, or similar role in the games industry, ideally on Unreal projects.

• Demonstrates deep expertise in Unreal Engine (UE4/UE5), particularly:

  • Unreal build and cook pipeline (UBT/UAT, cooking, packaging, deployment).

  • Editor extensibility with Slate and UMG (custom panels, tools, workflows).

  • Integrating editor/engine features with external tools and services.

• Has strong C# development experience, including:

  • Building and maintaining desktop tools (e.g., WPF).

  • Designing intuitive, performant UIs for technical workflows.

  • Architecting maintainable, testable tools that can evolve with project needs.

• Has hands-on production experience setting up and maintaining:

  • Horde build infrastructure (agents, queues, orchestration, scaling).

  • Unreal Game Sync (UGS) (streams, project definitions, build integration).

• Cloud DDC (configuration, deployment, tuning, monitoring).

  • Is comfortable with Perforce at scale: depot layout, streams, branching strategies, workspace management, and basic server-side administration.

  • Has solid scripting/programming skills beyond C# (e.g., Python, PowerShell, Bash), especially for automation and pipeline glue.

  • Understands CI/CD practices and has experience with systems like Jenkins, TeamCity, GitHub Actions, or Azure DevOps for Unreal-based projects.
