Senior Product Designer

Accountabilities: You will own the end-to-end headless product experience, balancing long-term design strategy with hands-on initiative delivery. Your work will help developers and AI agents move from initial API interactions to reliable production operations. Own the overall experience of APIs, CLIs, SDKs, configuration, and other headless product surfaces, maintaining consistent design quality across products. Define and evolve API and developer experience conventions, including design patterns, consistency, error handling, and documentation standards. Treat agent-facing interfaces, such as MCP servers, tool descriptions, schemas, and CLI outputs, as intentional product experiences. Establish standards for how AI agents discover, interact with, and recover from errors in APIs and tools. Define measurable indicators of agent experience, including task success rates, error recovery rates, and tool-call efficiency. Test and evaluate experiences with both human users and AI agents. Co-own assigned initiatives with Product Managers, shaping the headless customer journey from the first API call through production operations. Design agent journeys that enable AI systems to build, run, and operate solutions on users' behalf, including handling failed calls and recovery scenarios. Improve time to first production and strengthen customer confidence in operating the platform. Collaborate with Product, Forward Deployed Engineering, Marketing, and Legal teams on topics affecting the headless experience. Partner with UI/UX designers to ensure consistent terminology, patterns, and journeys across graphical and headless interfaces. Enable other builders through tools, training, guidance, and feedback on major initiatives, helping establish design quality beyond individual contributions. Requirements: The ideal candidate has a strong product design background with practical experience in APIs, developer tools, or platform products. You should be comfortable working closely with technical teams, translating complex systems into understandable experiences, and designing for both human users and AI agents. Proven product design experience with APIs, developer products, or platform experiences; this is a design-focused role rather than a purely engineering position. Experience working in B2B SaaS environments, ideally within highly regulated industries. Hands-on experience designing APIs, command-line interfaces, MCP servers, or tool schemas consumed by large language model (LLM) agents. Understanding of common agent-facing design challenges, such as ambiguous errors, non-idempotent calls, and undiscoverable capabilities. Experience designing agent-first or AI-first product experiences. Ability and willingness to use the product and understand its technical workflows. Ability to make abstract technical systems concrete, testable, and easy to explain. Confidence in collaborating with Product Managers and Engineering teams, challenging assumptions, and defending design decisions. Strong communication and cross-functional collaboration skills. Nice to have: Experience with automation or orchestration products. Experience evaluating agent interactions by running tasks against APIs or tools and using observed failures to improve the experience.
