Figma is growing our team of passionate creatives and builders on a mission to make design accessible to all. Figma’s platform helps teams bring ideas to life—whether you're brainstorming, creating a prototype, translating designs into code, or iterating with AI. From idea to product, Figma empowers teams to streamline workflows, move faster, and work together in real time from anywhere in the world. If you're excited to shape the future of design and collaboration, join us! The AI Product's Data Science org is at the center of the next generation of products at Figma, spanning Make, Figma Agent, Design Systems, and other areas. Data is critical to setting strategy and measurement across these areas. This org engages closely with AI Research and is a driving force behind our evals work and the future of product measurement at scale. With a charge to uplevel Figma’s use of data, the team works alongside other Data Scientists and Engineering to identify ways to implement and democratize new statistical methods, build data frameworks, and incorporate data within Figma’s product development process. This team contributes to the company’s goals by collaborating closely with product managers, engineers, and our finance team to uncover new opportunities, identify inefficiencies and recommend improvements through data-driven insights. As Director, you will lead a team of data scientists and managers, setting the vision for how data shapes strategy across Figma's AI products. You'll work closely with Product, Engineering, Design, and Research leadership to embed data-driven thinking and modern AI-product measurement into how we build. This is a full time role that can be held from one of our US hubs or remotely in the United States.

About the role (Remote) We're hiring a Senior Product Designer to join our global UX team. You'll own design within your product cluster — working directly with the engineers and PMs in those areas to define problems, shape solutions, and ship work that holds up. This is an end-to-end role. You lead discovery, define the interaction model, produce specs, and stay close through implementation. You're also expected to contribute to the systems and standards the whole team relies on. The Senior Product Designer will report to our Product Design Manager, and will work with our EU, UK and US based designers. You're part of a distributed team, so async clarity and proactive communication are as important as craft. What you’ll do Lead the design of complex AI-powered interactions in your product cluster, accounting for trust, transparency, fallback states, and human-in-the-loop considerations Embrace the use of modern AI-based tools like Claude, Figma Make, Cursor, Vercel, Loveable or equivalent not as theatre, but as a meaningful multiplier to your workflow. Partner with our UX research team to lead interviews, usability tests, and competitive analysis and translate findings into clear product direction and guidance Develop presentations, wireframes, mockups, and prototypes that effectively communicate interaction and design intent across web and mobile surfaces. Partner with PMs to shape requirements and with engineers to protect design intent through delivery Contribute to Showpad's design systems — adding components, documenting patterns, raising consistency across product areas Communicate design rationale through strategic storytelling: you can walk a PM, an engineer, and a senior stakeholder through the same decision and each one gets what they need Establish scalable AI-assisted workflows for your own work — research synthesis, rapid prototyping, concept generation — and help others on the team use them effectively Deliver UX solutions that measurably improve
