Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators. At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there. A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone. Why Roblox & Agent Infra The Agent Infra team builds the infrastructure that runs autonomous AI agents at Roblox for millions of creators building experiences on our platform, and for thousands of Roblox engineers shipping production code every day. Agent workloads break the assumptions most infrastructure is built on. They run for hours instead of milliseconds, they’re non-deterministic, they execute code nobody wrote, and they need real credentials against real systems to be useful at all. Making that safe, durable, and cost-effective at Roblox’s scale is the hard problem our team is solving. As an early member of the Agent Infra team, you’ll work alongside an experienced engineering team on systems that are already in front of real users, at scale, in a field that didn’t exist two years ago. You Are Demonstrated experience: 8+ years building and operating backend, distributed, or infrastructure systems in production, including systems you designed that held up at scale for years. Deep expertise in at least one of our core domains: workflow orchestration, scalable backend infrastructure, agentic runtimes, or secure sandboxing and access. Hands-on: You spend most of your time building,

For over 20 years, Smartsheet has empowered teams to manage work seamlessly and scale solutions smarter. Now, in our most ambitious chapter yet, we are uniting human teams with AI agents. By orchestrating the work agents do best, automating manual tasks and uncovering insights at scale, we create the space for people to focus on what truly matters: judgment, creativity, and big thinking. That is magic at work, and it’s what we show up for every day. Core Experiences owns the platform and front end behind Smartsheet's most used work surfaces. These are the sheets, reports, and dashboards millions of people open every day to plan, track, and run their work. Underneath them are petabytes of customer work data, one of the largest and most valuable datasets at the company. As AI agents join human teams, that data has to serve two very different users. People expect an instant, real-time collaborative experience. Agents read, write, and analyze at machine scale. Meeting both means rethinking how sheet data is stored, served, and moved between our operational systems and a world-class lakehouse platform. We hold that work to the highest standards of performance, reliability, and correctness. As a Principal Software Engineer on Core Views, you will set the technical direction for systems at the heart of Smartsheet. This is a hands-on architect role. You will spot the company's largest technical opportunities before they are obvious, prove them out with prototypes, and build alignment across engineering organizations, including on roadmaps you do not own. You will turn multi-quarter efforts into phased plans with clear milestones and candid risk reporting, then deliver them. You will make the hard trade-offs between latency, consistency, and cost. You will write the architecture decisions and standards other teams build on, and raise the technical bar for engineers across the company. Your first major initiative will reshape how sheet data moves between our transactional sto

The Digital Innovations Team (DigIT) is changing how Wizards develops, delivers, and manages the digital systems behind our games — for players, retailers, and the studios that develop our worlds. We are seeking a Principal Software Engineer who can guide product ideas through every stage with agentic AI — from defining the problem with business partners, to developing the system, to deploying it in production, and then improving it based on actual data. This job is not for those who have only observed AI changes from a distance. We need a hands-on creator. Someone who has directly shipped product to production by agentic AI, can provide the code and performance assessments, and can discuss in detail what was successful, what did not succeed,
