Every day, tens of millions of people from around the world come to Roblox to play, learn, work, and socialize in immersive digital experiences created by the community. Our vision is to build a platform that enables shared experiences among billions of users. This is what’s known as the metaverse: a persistent space where anyone can do just about anything they can imagine, from anywhere in the world and on any device. Join us and you’ll usher in a new category of human interaction while solving exceptional challenges that you won’t find anywhere else.

From the early days, simulated physics has been the foundation of the way users build in Roblox. Help our team add more fidelity and realism to Roblox experiences!

The Physics team develops Roblox's proprietary physics engine, which includes the dynamics of rigid bodies. The Fluids team creates real-time algorithms incorporating the effects of fluids in our physics engine. We use numerical methods to solve problems in game simulation for Roblox’s unique real-time, distributed, physics engine.

We're looking for someone with interest in working in real-time simulation systems with a focus on fluid mechanics. Experience in the games industry is a bonus.

You Have

  • Experience writing efficient C++ code (experience with Lua is a bonus)

  • Experience developing models for fluid dynamics, vehicle aerodynamics, free-surface flows, and/or multi-phase flows

  • A background in numerical methods for continuum mechanics

  • Experience with multithreading and SIMD is a plus

  • An understanding of modern computer architecture

  • A degree in engineering, physics, mathematics, or computer science

  • 3+ years of professional experience (or a recent graduate with an advanced degree in a relevant field)

You Will

  • Report to an Engineering Manager on the Physics Team

  • Develop new physics features, focussing on fluid dynamics, with an impact on Roblox developers and the experiences they build

  • Read research papers, invent and prototype new approaches

  • Improve robustness and performance of existing systems

  • Work with other teams and external developers to help them use our features, and solve the problems they might encounter

Role is located in San Mateo, CA, and onsite is required, with relocation covered as needed.
