About the role

What You'll Do

  • Own product work end to end. Partner with PM and engineering to define problems, explore solution spaces, validate concepts, and ship improvements that move key metrics — activation, time-to-first-filing, registration completion, customer-reported confidence.
  • Start in an LLM. Use Claude to clarify intent on ambiguous tax workflows, draft short PRDs, and surface edge cases (nexus thresholds, marketplace facilitator rules, exemption certificates, retroactive registrations).
  • Validate with self-serve research. Talk directly to controllers, AP leads, and founders running ecommerce, SaaS, and digital businesses. Run quick tests.
  • Prototype using AI tools. Use Cursor and Claude Code to build and iterate on flows against real product surfaces. Partner with engineers to decide what moves into the product.
  • Bring work into Figma. Translate validated concepts into full state coverage, system alignment, and production readiness — including tax-specific edge states (jurisdiction conflicts, filing errors, amendment flows).
  • Design for the 80 / 20. Encode judgment under the hood — let the internal tax engine do the heavy lifting — while keeping the default experience simple.
  • Contribute to patterns and culture. Share prompts, patterns, and learnings. Participate in crits and reviews.

What You Need

  • Experience as a product designer on complex products, ideally B2B, fintech, accounting, or other systems-heavy environments.
  • Ownership of projects from problem definition through launch and iteration.
  • Active use of LLMs like Claude or ChatGPT in your design workflow.
  • Comfort in Cursor or Claude Code.
  • A portfolio that shows strong product thinking, interaction design, and craft on dense, data-heavy surfaces.
  • Ability to work with PMs to define success metrics and adjust based on results.
  • Clear communication and comfort collaborating directly with engineers, PMs, and customers.

Nice to Haves

  • Experience planning and running customer interviews or usability tests with finance, accounting, or operations users.
  • Familiarity with design systems and extending shared components.
  • Comfort with front-end concepts (components, states, conditional logic).

What We Offer

  • Competitive salary and equity
  • Full medical, dental, and vision coverage
  • Wellness perks including Headspace and the Peloton One App
  • 401(k)
  • Lunch, dinner, and snacks in office
  • Regular team offsites and company events
