Design Engineer

About the Role: AI Gateway provides developers a unified API to connect applications and agents to hundreds of AI models, handling provider routing, billing, observability, and security controls. The Design Engineer will own product design and frontend implementation across multiple interfaces including dashboard, public model catalog, CLI, API responses, and code. Responsibilities include working with customers, product managers, and engineers to understand problems, explore solutions, build and ship production experiences, and learn from post-launch results. The role involves designing and building production experiences across website, dashboard, CLI, and APIs, making complex AI-related concepts understandable and creating extensible design patterns. The engineer will ensure quality after launch, including visual and interaction craft, accessibility, performance, resilience, and instrumentation, and will use coding agents to explore and implement ideas. What You Will Do: — Own product design and frontend implementation for the journey from discovering a model to operating AI in production. — Design and build production experiences across website, dashboard, CLI, and APIs. — Make models, providers, credentials, routing, budgets, logs, performance, privacy, and governance understandable and create extensible patterns. — Engage directly with customers and use product data to understand problems, define success, and improve the product. — Maintain quality after launch including accessibility, performance, and resilience. — Use coding agents to explore, test, debug, and take responsibility for shipped code. About You: — Demonstrated experience in identifying, designing, building, shipping, and learning from production-quality web applications. — Proficient in React and TypeScript, able to contribute confidently in a large codebase. — Strong visual and interaction design skills, able to make technical or data-rich products understandable while retaining advanced user control. — Comfortable working across graphical interfaces, CLI workflows, API behavior, and implementation details, with attention to accessibility, performance, failure recovery, and instrumentation. — Use customer research and product data to make decisions, communicate clearly, challenge ideas constructively, and adapt based on evidence. — Experience using coding agents daily, with ability to explain, test, debug, and take responsibility for code produced. — No required path; candidates may come from product design, frontend engineering, creative development, or other backgrounds. Bonus If You: — Have experience with developer tools, infrastructure products, model marketplaces, or observability. — 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 applications or agents with Vercel’s AI SDK or AI Gateway. Compensation & Benefits: — Competitive compensation package including equity. — Inclusive Healthcare Package. — Mentorship and support for professional growth including events. — Flexible Time Off. — Equipment and WFH budget provided. — Salary range for San Francisco base: $208,000 - $312,000 per year, adjusted by location.
