Design Engineer

The shape of it

In the posting’s own words

You will be the Design Engineer for AI Gateway, owning product design and frontend implementation across those surfaces. You will work with customers, a Product Manager, and engineers to understand the problem, explore solutions, build the production experience, ship it, and learn from what happens after launch.

What it asks for · 6

• Your work shows what you personally identified, designed, built, shipped, and learned after launch.
• You build production-quality web applications with React and TypeScript and can contribute confidently in a large, existing codebase.
• You bring strong visual and interaction craft and have made technical or data-rich products understandable without removing the control advanced users need.
• You can move between graphical interfaces, CLI workflows, API behavior, and implementation details, treating accessibility, performance, failure recovery, and instrumentation as part of the design.
• You use customer research and product data to make decisions, communicate your reasoning clearly, challenge ideas constructively, and change direction when the evidence changes.
• You use coding agents in your daily work, but you can explain, test, debug, and take responsibility for the code they help produce.

Also a plus

• Have experience with developer tools, infrastructure products, model marketplaces, or observability experiences.
• Have worked with AI models, providers, inference platforms, guardrails, or AI application tooling.
• Have experience with APIs, command-line tools, structured product content, or agent-facing interfaces.
• Have built an application or agent with Vercel’s AI SDK or AI Gateway.

What the job covers

• Own product design and frontend implementation for meaningful parts of the journey from discovering a model to making a first successful request and operating AI in production.
• Design and build production experiences across the website, dashboard, CLI, and APIs, choosing the right medium for each problem.
• Make models, providers, credentials, routing, budgets, logs, performance, privacy, and governance understandable, then create patterns that extend across new providers, modalities, and workloads.
• Talk directly with customers and use product data to understand problems, define success, make tradeoffs, and improve what ships.
• Own quality after launch, including visual and interaction craft, accessibility, performance, resilience, instrumentation, and edge cases.
• Use coding agents to explore and implement ideas quickly, while testing, debugging, and taking responsibility for what ships.
