About the Role

We are looking for a Senior Product Designer to own the design of a product area end-to-end—from strategy through shipped pixels. You will join a lean design team working on a sophisticated B2B platform, focusing on outcomes rather than just deliverables.

What We Value

• Design Craft: We prioritize interactions that work, flows that retain users, and systems that scale.
• Ownership: You see implementation as part of the job and close the gap between design and production.
• AI Literacy: We expect a thoughtful perspective on how AI changes interaction models, including handling uncertainty and latency.
• Candor: We value honest feedback as the fastest path to better work.
• Systems Thinking: We build patterns, not just one-off screens.

What You'll Do

• Own the design of a product area end-to-end, including strategy, flows, and edge cases.
• Partner with engineering during implementation, including contributing directly in code (Pluma components, UI fixes, prototypes).
• Actively contribute to and steward our design system, Pluma.
• Develop a point of view on AI within your product area, focusing on interaction design.
• Partner with PM and Engineering on roadmap and tradeoffs.
• Mentor designers through pairing and critique.

What We're Looking For

• 5+ years of product design experience with a portfolio demonstrating craft and ownership.
• Strong flow literacy: ability to design end-to-end experiences across states and recovery paths.
• Code fluency: experience contributing directly to production UI or interaction prototypes.
• Experience as a power user of a design system.
• Proven experience designing AI-involved interfaces.
• B2B SaaS experience with complex, data-driven interfaces.

Compensation & Benefits

• Salary: $171k–$193k USD.
• Insurance: 100% coverage of medical, dental, vision, mental health, and supplemental insurance for you and your family.
• Time Off: Unlimited PTO and 16 weeks paid parental leave.
• Support: Stipends for remote work and wellness, plus a professional development budget.
