About the role

What you will do

  • Own and lead product design across your squad, setting design direction and raising the bar for craft, quality, and strategic thinking.
  • Build for AI agents as first class users. You won't just be designing a compelling experience for human users, you will also ensure that the product works exceptionally well for our silicon-based users too!
  • Integrate AI into every stage of your design workflow, leveraging it to accelerate research synthesis, automate repetitive tasks, and explore high-fidelity prototypes more efficiently.
  • Listen to our users and customers to understand their needs. Develop a deep understanding of the SDLC and how we can enable developers and AI agents to produce better quality software.
  • Work closely with other product designers to ensure a cohesive information architecture and a unified experience across the entire product platform.
  • Align with your product manager on problem definition, providing design solutions throughout the end-to-end development stage.
  • Partner with engineering teams early in the design process to vet technical feasibility and uncover edge cases.
  • Mentor fellow designers through critique, pairing, and feedback — actively investing in the team's growth and raising collective craft.
  • Shape and advance the Product Design team's processes, tools, and collaborative frameworks — not just contributing to them, but taking genuine ownership of their evolution.
  • Have the opportunity to work and experiment daily with a variety of AI tools and models, doing real work.

Experience and qualifications

  • Experience organizing complex environments into logical structures and mapping user journeys that minimize friction.
  • Demonstrated curiosity and practical experience using AI tools to accelerate research, ideation and design velocity.
  • A self-starter mindset with the drive to identify UX gaps and propose structural improvements without being prompted.
  • Ability to articulate design decisions and the "why" behind them to both technical and non-technical stakeholders.
  • Comfort working in a cross-functional environment where feedback is shared openly and success is a team effort.
  • Delivery mindset. Your role does not end when the design is handed off.
  • Track record of driving design strategy and establishing patterns that scale beyond your immediate squad — influencing the broader product and design organization.
  • Familiarity with software development workflows, the SDLC, or a background in computer science — you don't need to write production code, but you need to think alongside engineers who do.
  • Experience designing AI workflows or agent-driven experiences is a strong plus, and will meaningfully shorten your onboarding ramp.
