Software Engineer (Engine Scalability)

Roblox

Join Roblox as a Software Engineer on the Engine Scalability team. You'll design and ship 3D engine systems for avatars and environments, improve game engine performance across devices, and collaborate with various teams. A strong background in C++ and real-time performance is required.

Responsibilities

  • Design and ship 3D engine systems for avatar and environment geometry, including mesh processing, level of detail, transcoding, streaming, runtime loading, and related performance systems.
  • Profile and improve the performance of our game engine across a wide range of devices, with particular attention to mobile.
  • Drive projects end-to-end, collaborate with other engineers, and contribute to maintaining strong technical quality and code health on the team.
  • Ownership in Ambiguity: A track record of driving work end-to-end when the problem wasn't fully specified: defining the approach yourself, seeing it through implementation, rollout, and production consequences; gathering more information when requirements didn't make sense

Requirements

  • Applied 3D Systems Experience: Demonstrated hands-on experience building production systems involving real-time 3D rendering, mesh or geometry processing, LOD, animation/skinning, spatial data, 3D asset pipelines, or GPU/client performance. Not required, but a major plus
  • Collaboration and Communication: Ability to work effectively across teams (Engine, Rendering, Avatar, Studio, and developer-facing teams) and explain complex technical topics clearly to different audiences
  • Strong C++ Experience: Deep proficiency in C++, with a focus on writing clean, efficient, and maintainable code in large codebases
  • Real-time Performance Mindset: Experience diagnosing tradeoffs among CPU/GPU time, memory, loading latency, visual quality, and frame-time stability on constrained platforms such as mobile or console

Preferred

  • Experience: 3+ years of professional experience building and shipping high-performance systems in domains such as game engines, real-time simulation, robotics, AR/VR, or similar
