Are these based on real engineering roles?
Yes. The catalog is built around real engineering role patterns so the practice round feels closer to a live interview.

Vercel
Backend
Senior Software Engineer, Trust & Safety
Develop the platform that detects and prevents fraud, phishing, and abuse across Vercel's deployment and hosting products, building automated signals and enforcement pipelines that act on large volumes of accounts and traffic. The work combines backend data pipelines with policy enforcement and investigation tooling. An interview would probe designing event-driven detection pipelines, balancing precision versus recall on abuse signals, and building idempotent, auditable enforcement actions over a high-volume dataset.

Fullstack
Software Engineer, AI SDK
Build and maintain the Vercel AI SDK, the TypeScript toolkit developers use to stream LLM responses, call tools, and wire generative UI into web apps across many model providers. The work spans provider abstractions, streaming protocols, structured-output handling, and tight integration with React and Next.js. An interview for this role would explore API design for a multi-provider abstraction, streaming and backpressure in Node, and how to model tool-calling and structured generation cleanly in TypeScript.

Security
Software Engineer, CDN Security
Build the systems on Vercel's global edge network that detect malicious traffic and protect customers, including the scalable firewall and DDoS-mitigation layers that analyze requests at the CDN tier. The role mixes high-throughput, low-latency edge engineering with adversarial threat modeling. A technical interview would dig into HTTP and TCP/IP fundamentals, designing rate-limiting and rule-matching engines that run at edge scale, and reasoning about attacker behavior and false-positive tradeoffs.
GoRustNetworkingVercel
Frontend
Software Engineer, Next.js
Work on the Next.js open-source framework that powers a large share of the React ecosystem, building features across the App Router, React Server Components, and the Rust-based Turbopack bundler and compiler. You would balance developer ergonomics with build performance while shepherding changes through a heavily-used public repo and large community. A technical interview would probe deep understanding of React rendering and hydration internals, bundler/compiler design tradeoffs, and how to evolve a framework API without breaking millions of downstream apps.
