Senior Staff Software Engineer, Client Architecture

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 new contribution formats plug natively into the composers on every client, including formats that started on our Developer Platform. Unblock execution on the pillar's highest-upside bets.
• Drive experimentation rigor
• Partner with Data Science on metric strategy for net-new features. Give engineers a clear recipe for designing and reading experiments, and make the call to iterate or kill when results come back flat.
• Bring AI into contribution thoughtfully: Shape where LLMs help people create, from inspiration at the start of the journey to routing and labeling at the end, while the content itself stays human. Model effective use of AI-assisted development tools, with rigorous judgment over what they produce.
• Lead beyond your team: Write the technical direction and get partner teams to adopt it: client platform, search, feeds, trust and safety, and the developer platform. Negotiate priorities and migrations, and mentor senior and staff engineers on every client.
• Raise the bar on client performance and reliability
• Own composer success rates, latency, and crash budgets across platforms. Spot recurring pain points across technical designs and fix them at the root.
