Roblox is a human co-experience platform.\u00a0 We want our users to be able to experience the full spectrum of social interactions in our immersive 3D experiences, with communication on Roblox mirroring all the ways we communicate in the real world.\u00a0 One of the cross-functional teams building this technology on Roblox is the User Group.\u00a0<\/span><\/p>\n

\u201cWe believe that expressive and immersive communication is the future,\u201d said Garima Sinha, Senior Director of Product. \u201cWe are at that juncture where the technologies that we\u2019ve been working on for years are coming together. When you are in a virtual experience, you can see expressions. Soon, you\u2019ll be able to feel the body language, the vibe of people being in the same room.\u201d\u00a0<\/span><\/p>\n

The User Group\u2019s vision is to enable one billion people to communicate, play, learn, and work together in high-quality immersive 3D experiences. \u201c[Our vision] has stayed pretty consistent over the past three years,\u201d said Philippe Clavel, Senior Director of Engineering. \u201cWe want to build a platform that empowers people to connect and engage together.\u201d\u00a0<\/span><\/p>\n

But as Philippe explains, building it in the right way is just as important as getting the technology behind it working. \u201cRoblox is inherently a social product. There\u2019s still so much potential for what it can do. But we also have to make sure that we are building our products in a safe and civil way.\u201d\u00a0<\/span><\/p>\n

Together, Garima and Philippe lead teams within the broader User Group at Roblox that are tackling some of Roblox\u2019s toughest technical challenges to bring this vision to life. To learn more about what they are up to, we spoke with them and two other members of the User Group: Principal Product Manager Effie Goenawan and Engineering Manager Irene Nguyen.\u00a0<\/span><\/p>\n

The Technical Challenges Behind Virtual Communication and Connection<\/b><\/h2>\n

Philippe reminisced on a moment from his Roblox job interview. \u201cDuring my interview, CEO and Co-Founder Dave Baszucki explained to me that in the 3D world, you can be and interact with anyone. But before you can do that, you must be able to communicate effectively. Our vision is to enable and mimic real-world communication.\u201d<\/span><\/p>\n

By adding <\/span>voice communication to our Chat feature<\/span>, we are getting closer to this vision.\u00a0 This new functionality allows users 13 and older to communicate using their voice in Roblox experiences. The technology is proximity-based and simulates realistic communication.<\/span><\/p>\n

<\/p>\n

The User Group, including cross-functional efforts from the Safety and Engine Groups, has tackled several technical challenges to bring Chat with voice to life \u2013 one of the toughest being building the architecture. \u201cBuilding the technology behind Chat with voice is inherently complex. To make it feel immersive and mirror real-world communication, we enable sound so that it is tied to your avatar\u2019s location within a 3D space. You want others who are near you to hear you \u2013 not those far away,\u201d said Philippe.<\/span><\/p>\n

\u201cOn top of that, when we deploy new features, it\u2019s to millions of users across the globe. We made sure to deploy this new service at the edge to guarantee that our voice servers are close to our users. We want you to have a good discussion wherever you are.\u201d<\/span><\/p>\n

Ensuring that we built this feature with <\/span>safety<\/span> and civility in mind is also a critical technical challenge. \u201cOur top priority is making sure that we roll out Chat with voice safely and responsibly. While we\u2019ve already implemented robust safety features (e.g. moderation tools), we are also looking at technology solutions to ensure safety and civility on our platform,\u201d said Effie.\u00a0<\/span><\/p>\n

Culture of Innovation in the User Group<\/b><\/h2>\n

While our company values act as a guide anyone can use to solve our technical challenges, <\/span>each team brings its own collaborative and creative approach to developing innovative solutions.\u00a0 Here are some of the ways that the User Group comes together to drive a culture of innovation for Roblox.\u00a0<\/span><\/p>\n

Solving tough technical challenges is what motivates them.\u00a0<\/b><\/em><\/p>\n

Finding the right solution to technical challenges is rarely clear or straightforward. Effie encourages her team to leave no stone unturned when trying to find solutions.<\/span><\/p>\n

When it involves solving for safety and civility, \u201cOne easy solution would be to spend lots of time and resources on manual moderation, but we are responsible for making the right decisions for our team and the business. That\u2019s why we are starting to look at ways that we can tackle this problem with the best technology solutions to support our moderation efforts.\u201d One of those technical challenges is moderating the Chat with voice feature.<\/span><\/p>\n

\u201cWe need to be able to detect and take action in real time to ensure the safety of our community,\u201d said Garima. \u201cThese are hard technical problems that no one in the industry has solved yet. What makes the culture of our team unique is that we all have the drive to make it happen. We are solving some of the hardest problems in the world. And our people take a lot of pride in solving these hard problems.\u201d<\/span><\/p>\n

Iteration is what helps them develop great solutions.\u00a0<\/em><\/strong><\/p>\n

Even when facing blockers, the User Group has kept its eye on the ball. For Irene Nguyen, developing MVPs (Minimum Viable Product) and proofs of concept is part of the process. As an Engineering Manager on the Connections Team within the User Group, Irene supports users\u2019 abilities to connect, experience, and create memories with friends. One technical challenge her team is helping to solve is enabling video capture functionality within the Roblox platform. Her team\u2019s goal is to enable users to quickly and easily share great moments from Roblox with their friends.\u00a0<\/span><\/p>\n

\u201cWhat are our current limitations in video quality? What does this mean across devices? Performance? We want to build it right and build it for all.\u201d Identifying where to begin can be overwhelming, but maintaining an iterative mindset helps Irene and her team balance priorities and forward momentum.\u00a0<\/span><\/p>\n

\u201cWe need to identify our starting point, be clear about our vision, and then lay out the steps needed to build an MVP that will get us there. By following that process, the team is able to see and get really pumped about what\u2019s possible.\u201d She recalls, \u201csome people equate an MVP with a hack or workaround solution. Instead, I think of it as a way for us to prove the viability of whatever we\u2019re working on. Iteration is how we end up with a great solution.\u201d\u00a0<\/span><\/p>\n

Open communication and collaboration enable anyone to share new ideas and problem solve.\u00a0<\/b><\/em><\/p>\n

What is the secret to sparking innovation across the team? Philippe thinks that it\u2019s fostering a bottom-up development culture, encouraging open communication, and asking the right questions.\u00a0<\/span><\/p>\n

\u201cYou don\u2019t hire smart people to tell them what to do. You hire smart people, so they tell you. As a manager, my job is to help our team by asking constructive questions,\u201d said Philippe. \u201cThis style has helped our team seek better solutions and achieve results. Asking questions allows our team members to think about things differently. I find that they speak up about their perspectives. And most importantly, they openly share when they disagree.\u201d\u00a0<\/span><\/p>\n

Recently, Philippe\u2019s team debated how they should render spatial audio (the technology powering Chat with voice). \u201cSay that you\u2019re in the experience with your avatar. <\/span>Should we render the audio as if it is coming to your avatar\u2019s ears or to the game camera?<\/span> There was a very strong argument for both ways, so we solved for both and voted on what felt best. And, in true Roblox fashion, <\/span>we also allow developers to customize it and change the default setting.<\/span>\u201d<\/span><\/p>\n

<\/p>\n

The User Group has also started to host internal tech talks to foster communication and collaboration. In Irene\u2019s words, \u201cWe take pride in knowledge-sharing across the various teams in the User Group. They [tech talks] are a way that we all stay connected and share what\u2019s happening across our team. Doing this has led us to tackling other big questions.\u201d<\/span><\/p>\n

These tech talks have had other benefits, especially for junior members. Anyone is able to practice their public speaking skills, show off what they\u2019ve been building, and even get real-time feedback.\u00a0<\/span><\/p>\n

\u201cThere can never be too many forums for people to showcase what they\u2019re building,\u201d says Irene. \u201cWe\u2019re hoping to expand the tech talks and make them even bigger in 2023.\u201d<\/span><\/p>\n

Join the Team Helping to Shape the Future of Human Connection and Communication.<\/b><\/h2>\n

The User Group has ambitious plans for 2023. So what are some of the reasons that you\u2019d want to join the team? For Effie, it\u2019s the opportunity to make an impact. \u201cThe problem space that you have the potential to impact is huge. Whether it\u2019s technical, machine learning, optimization, user experience, or even policy, we\u2019re leaders in an industry where there is such a greenfield of problems that have never been solved.\u201d<\/span><\/p>\n
