Software Engineer, Engine Scalability

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.
• Partner closely with other teams (Rendering, Avatar, Studio) and external developers so that the features you build are directly usable to create amazing experiences.
• 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.

Requirements

• 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.
• Deep proficiency in C++, with a focus on writing clean, efficient, and maintainable code in large codebases.
• Experience diagnosing tradeoffs among CPU/GPU time, memory, loading latency, visual quality, and frame-time stability on constrained platforms such as mobile or console.

Real-time Performance Mindset

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.

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.

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.
