The Opportunity

At Mozilla, we believe that the “metaverse” – like the internet itself – should be open and accessible to all. That’s why we’re building Hubs.

Hubs empowers communities to gather in safe, private, decentralized virtual spaces where they are in control. Hubs fosters creativity and connection at a time when online interactions often lack the spontaneity and opportunity to delight, inspire, and build trust between people.

As a Senior Gameplay Engineer, you will leverage and hone your game development skills to build the core client, engine, and art tools powering the Hubs product suite.

What You'll Get To Do

Build delightful experiences in the Hubs application (and its underlying game engine) 

Build tools for artists and developers to bring their creative visions to life

Work through the core problems of interactive 3D games including multiplayer networking, graphics, audio, avatars, IK, animation, physics, and performance optimization.

Share your knowledge and support community developers building addons and their own applications based on Hubs.

Work transparently on open source software and participate in standardization and interoperability efforts to protect a user-respecting future for immersive applications.

As an ideal candidate…

You have professional game programming experience 

You care about speed, simplicity and pragmatism in your approach to coding and problem solving

You have deep domain knowledge of relevant topics like:

Game mechanics, camera systems, simulation, and scripting

Three.js, 3D Math, Graphics/Rendering

Game engine internals, whether your favorite engine is Unity, Unreal, Godot, a proprietary engine or one you wrote yourself

Javascript/Typescript, browser runtimes, and performance

Web apis like WebGL/WebGPU, WebAudio, WebRTC, WASM

Internet architecture/topology/protocols and web standards

Hardware-aware optimization techniques

Artist tooling and asset pipelines

You prefer to join a small team solving many problems rather than focusing on one part of a large game / game engine.

You enjoy variety in your work: from game engine internals, to gameplay mechanics and tools for artists.

You express your ideas clearly in written and spoken English.

You have 4+ years of professional programming experience, preferably in related domains.

Bonus points if…

You have spent many years in the games industry and can bring the wisdom of that domain to the interactive web. 

You contribute to open-source projects.
