Level: Senior IC (5+ years)

About the role

We're looking for a Senior Product Designer to work across multiple product areas — moving fluidly between initiatives, framing the problems worth solving, and taking work from discovery through research, interaction and visual design, to shipped, measured outcomes. This is a senior individual-contributor role: you'll set design direction, raise the bar on craft, juggle competing priorities, and communicate clearly with product and engineering to align on what to build and why. Strong communication is central to success here — much of your impact comes from how well you explain your thinking and bring others along.

How senior designers work has changed meaningfully over the past two years. We expect AI to be part of your delivery workflow — using AI tools to move faster and with more leverage across research synthesis, ideation, prototyping, and production. Judgment, strategy, and craft matter more than ever; AI raises the floor on execution, so the differentiator is knowing what's worth building, working efficiently across several areas at once, and holding the quality bar on how the product feels to use.

What you'll do

• Design across multiple product areas at once, prioritizing well and giving each the design direction and craft it needs.

• Drive projects end-to-end through discovery to shipped work — user flows, interaction design, prototypes, and polished, accessible UI that meets our design-system standards.

• Use AI tools as a core part of how you deliver — AI-assisted research synthesis, rapid concept generation, and prompt-to-prototype (including light "vibe coding" with tools like Cursor, v0, Lovable, or Claude) to explore and validate ideas in higher fidelity, faster.

• Run and interpret real user research and use evidence and usage instrumentation to validate opportunities and measure impact after launch.

• Collaborate cross-functionally with product and engineering on strategy and scope, communicating design decisions and their rationale clearly to both technical and non-technical audiences, and contributing reusable patterns back to the design system.

• Communicate and advocate for your work — write and present clearly, tell the story behind a design, align stakeholders, and build shared understanding across the team.

• Level up other designers through critique, mentorship, and by sharing effective AI-augmented design practices across the team.

What we're looking for

Core craft (non-negotiable)

• 5+ years designing and shipping digital products, with a portfolio showing measurable outcomes — not just screens.

• Excellent interaction and visual craft; strong command of a modern design tool (e.g., Figma) and design-system thinking.

• Fluency in user-centered methods, accessibility standards, and platform patterns across web and mobile.

• Strong product sense and systems thinking — you frame problems, weigh trade-offs, and communicate the reasoning behind decisions.

• Proven ability to manage multiple projects and shifting priorities at once without dropping quality.

AI in your workflow (expected)

• Hands-on experience using AI tools (e.g., Figma AI, Claude, Cursor, v0, Lovable) as part of how you deliver — research synthesis, ideation, and prompt-to-prototype — and good judgment about where they help versus where they don't.

• You're actively experimenting with these tools, not waiting to see what happens — and you share what works with the team.

• A working understanding of how modern AI systems behave — the capabilities and limits of LLMs — enough to collaborate credibly with product and engineering as AI shows up in more of what we build.

Communication (core to this role)

• An exceptional communicator in writing, conversation, and presentation — you make complex design decisions easy to understand and rally people behind them.

• You proactively share context, tell the story behind your work, and align stakeholders across design, product, and engineering.

• You give and receive sharp, constructive critique and keep partners informed as work evolves — especially while juggling multiple projects.

How you work

• Self-directed and comfortable with ambiguity; you can turn a vague problem into a shipped solution.

• A mentor who raises the craft and AI capability of the people around you.

Nice to have

• Comfort prototyping in code or with AI code tools to communicate intent to engineering.

• Experience designing AI-powered features, or a credible grasp of the UX patterns involved — useful as AI becomes a bigger part of our roadmap.

• Prior experience in B2B SaaS or a high-growth product environment.

How we'll evaluate candidates

We care most about judgment, craft, and communication. Expect a portfolio review where you walk us through your reasoning and outcomes (not just visuals) and articulate the trade-offs behind your decisions, a working session, and conversations with product and engineering partners. Come ready to talk about how you've used AI to work faster and where you chose not to, and about how you manage several projects at once.
