About the Role We are looking for a Staff Software Engineer - Frontend to help us solve some of the hardest frontend problems as we build AI products at scale. This is a hands-on technical leadership role. You will work on problems involving real-time systems, streaming, performance, reliability, complex user workflows, and large-scale frontend architecture. You will also help shape the way frontend engineering is done across the organization. WHAT YOU'LL DO - Own the frontend architecture for complex, high-scale applications. - Solve challenging problems around real-time interactions, streaming data, asynchronous workflows, and continuously changing UI state. - Build reliable experiences around AI-generated responses, long-running tasks, tool calls, and partial results. - Design systems that remain responsive and reliable when dealing with large amounts of data and long-running operations. - Work closely with backend, product, and design teams to solve problems end to end. - Identify architectural bottlenecks before they become scaling problems and drive the right long-term solutions. - Improve frontend performance across loading, rendering, network usage, memory, and bundle size. - Build reusable frontend infrastructure, components, and patterns that can be adopted across teams. - Improve observability and production debugging through metrics, logging, error tracking, traces, and monitoring. - Own complex production issues, identify root causes, and make sure the same problems don't keep coming back. - Establish better approaches to testing, releases, feature flags, CI/CD, and frontend reliability. - Lead architecture discussions and technical decisions across teams. - Mentor engineers and help raise the overall frontend engineering bar. - Take ambiguous problems from problem definition → design → implementation → production. WHAT WE'RE LOOKING FOR - 8+ years of software engineering experience, with strong hands-on frontend experience. - Deep experience with JavaScript, TypeScript, React, and Next.js. - Strong understanding of frontend architecture, browser fundamentals, networking, rendering, and the web platform. - Experience designing and scaling large production frontend applications. - Strong understanding of state management, APIs, caching, authentication, and asynchronous systems. - Experience building real-time or streaming experiences using technologies such as WebSockets, SSE, or streaming APIs. - Strong understanding of web performance and experience solving real production performance problems. - Experience with frontend observability and debugging production issues. - Experience building shared components, design systems, or frontend platforms. - Strong system-design skills and the ability to make practical architectural trade-offs. - Ability to influence technical decisions across teams without relying on formal authority. - Strong ownership and a bias toward solving problems at their root. - Understanding of video and audio fundamentals, including media processing, encoding/decoding, formats, streaming, synchronization, and handling media workflows at scale. - Experience building frontend experiences for video/audio processing or dubbing workflows is highly valuable. - Understanding of document digitization workflows, including document upload, processing states, previews, extraction results, editing/review experiences, and handling large or complex documents. - Experience building frontend applications that deal with large files, long-running processing jobs, progress tracking, retries, failures, and partial results.
