# Software Engineer, 3D Engine Scalability

- **Company:** Roblox
- **Location:** San Mateo, CA, United States
- **Experience:** Expert
- **Salary:** $243,290.0 - $295,250.0
- **Contract:** Permanent contract
- **Skills:** Clean Code Principles, Computer Animation, 3D Rendering, C++ (Programming Language), Game Engine, Real Time Simulation, Spatial Data Infrastructures, Transcoding, Low Latency

## About the Role

* Proven Expertise: 8+ years of professional experience building and shipping high-performance systems in domains such as game engines, real-time simulation, robotics, AR/VR, or similar.
 * Strong C++ Experience: Deep proficiency in C++, with a focus on writing clean, efficient, and maintainable code in large codebases.
 * Applied 3D Systems Experience: Demonstrated hands-on experience building at least one production system involving real-time 3D rendering, mesh or geometry processing, LOD, animation/skinning, spatial data, 3D asset pipelines, or GPU/client performance. Deep specialization in one area is not required, but meaningful hands-on experience is.
 * 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.
 * 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.

## Description

* 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.
 * Lead by example: drive projects end-to-end, mentor other engineers, and help set a high bar for technical quality and code health on the team.
