Role
Who you are
- 5+ years of experience shipping high-complexity software and supporting mission-critical applications at scale
- Experience architecting, designing, and leading implementation across a wide range of software products and systems
- Experience building AI infrastructure, including systems for model serving, orchestration, reliability, and production observability
- Familiarity with agentic systems and multi-step execution loops, including planning, tool use, recovery, and long-running workflows
- Understanding of tools, skills, and evaluation frameworks for AI systems, including how to design reliable tool interfaces, improve capability coverage, and measure quality through structured evals
- Expertise in component-based libraries and frameworks, with a strong grasp of building performant, high-quality user experiences
- Proficiency in C++, C#, Java, or similar programming languages
- Strong understanding of SQL and NoSQL systems at scale
- Deep understanding of the components required to build modern large-scale infrastructure, with the judgment to evaluate tradeoffs, recommend pragmatic solutions, and align engineers around a direction
What the job involves
- You'll build the agentic AI system that powers creation for millions of Roblox creators. The Assistant team is converging Studio Assistant (desktop) and Build (mobile) into a single cloud-native architecture — one harness, one tool set, one eval framework
- You'll work across the full stack: cloud orchestration, LLM integration and model routing, tool/skill execution, and the creator-facing client. The system orchestrates multi-step creation workflows end-to-end: planning, code generation, asset creation, and automated testing
- 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
- Work on a variety of unique technical challenges within complex systems
- Be a technical bar-raiser for high code quality, architectural designs, and long-term planning
- Develop fellow engineers on the team
Our take
Online gaming may be a well-established space, but Roblox has distinguished itself as a leader by empowering its community to build, share, and profit from their own creations - turning game development into an accessible, rewarding ecosystem for millions of users.
In addition to standard games, the platform offers virtual worlds and other experiences to explore and interact with. Its platform provides an online ecosystem for millions to create, socialize, chat, and explore immersive experiences with friends. In fact, in the US its used by two-thirds of children aged 9 to 12.
The platform has faced scrutiny over user safety, but responded by strengthen parental controls and launching initiatives like its "Parents Council". This move to address these issues, atop its strong financial performance and record payouts to developers, showcase Roblox's trajectory as one of innovation and impressive growth.
