Senior Software Engineer, Creator Collaboration

About the Role

As a Senior Engineer on the Collaboration team, you will design and build the services that let creators work together, and increasingly, that let AI agents work alongside them. One of the areas is our flagship Team Create product, which enables creators to collaborate in real time with friends and coworkers. Just as important is the Creation Platform underneath it: the APIs and services that power external agents through MCP, along with Build on Roblox and other agentic products. You will be solving problems in scale, architecture, and design to build software that supports larger and better collaboration between teams of developers, artists, and the agents they bring into the loop. The ideal candidate has full-stack knowledge, experience on large-scale systems, enjoys solving complex software problems and has a passion for mentoring other engineers on the team.

Responsibilities

• Help and understand the needs of the community that uses our software, from beginning artists to professional scripters and designers.
• Take ownership and responsibility for designing, building, testing, and deploying services within the Roblox ecosystem.
• Own the Creation Platform that powers agentic products, including the APIs and services that agents reach through MCP.
• Be a technical bar-raiser for high code quality, architectural designs, and long-term planning along with mentoring fellow engineers on the team.

Requirements

• 7+ years shipping high complexity code.
• Experience architecting, designing, and leading implementation of a wide array of software products.
• Experience supporting mission-critical applications at scale.
• Proficiency in C#, C++, Java, Python, or similar programming languages.
• Familiarity with agentic systems, harnesses, and models.
• Understanding of SQL and NoSQL databases at scale.
• Understanding of the components required to build modern large-scale infrastructure, with ability to recommend routes and bring consensus.
• Comfortable designing platforms and APIs that other products, including AI agents, build on top of.
• Familiarity with MCP or similar agent tooling is a plus.

Work Arrangement

Roles based at the headquarters in San Mateo, CA are onsite Tuesday, Wednesday, and Thursday, with optional presence on Monday and Friday.
