Staff Product Engineer

THE OPPORTUNITY: We're looking for a Staff Product Engineer to set the bar for the craft, architecture, and quality of everything teachers and students see and touch in Brisk. You'll own the frontend at a deep technical level — the React patterns we lean on, the browser-extension surface that brings Brisk into the tools educators already use, and the performance and accessibility standards we hold the product to. This is a senior individual contributor role with broad influence. You'll shape direction across our frontend codebase, raise the bar through code review and mentorship, and ship features that millions of teachers rely on every day. The Brisk Extension lives inside Google Docs, Slides, YouTube, Microsoft Word and PowerPoint online, and a growing list of other surfaces, which means the frontend is, in many ways, the product itself. YOU WILL: - Set technical direction for our frontend architecture, patterns, and tooling, and bring the team along with you. - Lead complex UI work in React and TypeScript across the Brisk Extension, Brisk Next, and Brisk Boost. - Push the Brisk Extension forward across Google Workspace, Microsoft 365, and beyond — DOM integration, content scripts, message passing, storage APIs, manifest evolution, and the browser APIs that make our in-the-tool experience possible. - Reverse-engineer external surfaces when the documented APIs don't go far enough — read the network calls, study the DOM, and find the seams that let us build integrations our competitors can't. - Stand up the telemetry, instrumentation, and active monitoring that keep us honest — frontend logging, error tracking, real user monitoring, and Datadog dashboards that tell us what's happening before users do. - Own frontend performance: bundle size, rendering paths, runtime profiling, and Core Web Vitals. Set the targets, build the dashboards, and ship the changes that move the numbers. - Champion accessibility as a baseline rather than an afterthought, so every teacher and every student can use what we build — semantic HTML, ARIA, keyboard navigation, and screen reader support are expected, not bolted on. - Build and evolve the Brisk design system so the rest of the team ships faster and the product feels coherent across surfaces. - Define our testing strategy across unit, integration, and end-to-end layers, and keep the suite fast and trustworthy as the codebase grows. - Mentor engineers, raise the bar on code review, and partner closely with design, product, and the founding team to shape what we build. - Contribute to backend services in Python and Flask when a feature needs it, and stay close to the API contracts that connect frontend to back. - Devise database persistence architecture, including RDBMS schema or KVS key structure, to store data backing high traffic interfaces.
