Reddit is a community of communities. It’s built on shared interests, passion, and trust, and is home to the most open and authentic conversations on the internet. Every day, Reddit users submit, vote, and comment on the topics they care most about. With 100,000+ active communities and approximately 130 million daily active unique visitors, Reddit is one of the internet’s largest sources of information. For more information, visit www.redditinc.com . Reddit is where 130M+ people a day come to share what they know, ask what they don't, and find their people. Every post, comment, and new format starts with our composers. We're looking for a Senior Staff engineer to be the technical anchor for how people create on Reddit across Web, iOS, and Android. You'll own the cross-client vision for contribution. That means one shared content model and set of client contracts that all three platforms build against, the performance and reliability engines underneath, and the creation surfaces on top. Our modernized composers are now live on every platform, so the next chapter is growth: making video a first-class way to create, bringing new formats to every user, and using AI to inspire contribution without writing it for people. Every bet has to earn its way through an experiment, so you'll pair architectural judgment with real rigor about what moves the metrics. This is an IC leadership role, partnering directly with Product, Design, and Data Science leadership. Key Responsibilities: Own the cross-client architecture: Define the shared contracts that Web, iOS, and Android build against, including our rich content model, GraphQL schemas, and shared UI primitives. A feature should be designed once and shipped natively everywhere, not built three bespoke ways. Make video and media first-class: Set the client architecture for video creation, editing, drafts, and upload, built to survive bad networks, app restarts, and lower-end devices. Bring new formats to every user: Establish how

About Ramp Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $200B in annualized spend flows in and out of 70,000+ companies: authorizing payments, flagging risk, categorizing spend, and closing books. The problems are high-stakes, data-dense, and unforgiving. We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you’ve built. At Ramp, everyone is a builder who owns problems end to end and makes consequential decisions that shape the outcome. The median Ramp customer saves 5% and grows revenue 16% in their first year – far in excess of businesses operating without Ramp. We believe every ambitious company deserves the same.

This is a frontend-leaning role for an engineer who obsesses over interaction design and data-dense UX, but is just as comfortable designing the API that feeds it. You'll own the surfaces customers actually touch: agentic financial analysis, month-end close, and exploratory data experiences that feel as polished as the best business intelligence tools. If you want your frontend work to sit at the center of real production LLM systems rather than being bolted on at the end, this is the role. What You’ll Do Design and ship customer-facing AI experiences end to end, from React UI through to the APIs and data contracts behind them Build BI-tool-quality interfaces for agentic analysis, FP&A, and book-close workflows:

About Mixpanel Mixpanel is the leading product intelligence and analytics platform, trusted by more than 29,000 companies to help understand how people use the products they build. By combining powerful analytics with AI that knows your business, Mixpanel helps teams see what’s working, diagnose what’s not, and decide what to build next. Learn more at mixpanel.com . About The Role Data governance is one of the most critical challenges for Mixpanel's enterprise customers, and the AI era turns it into a foundational problem. Analytics and agents are only as trustworthy as the data beneath them.
