Principal Product Designer

Requirements

• 8+ years of experience in a fast-paced D2C product design environment
• Strong principal-level IC craft: you’re deeply hands-on, credible in the details, and capable of leading through influence rather than direct management
• Player-coach mindset: while this is not a formal people management role, you naturally mentor and elevate other designers through collaboration, feedback, and example-setting
• Senior product design leadership: strong end-to-end product sense, systems thinking, and a track record shipping great work with Product and Engineering in a fast environment
• Intellectually curious and self-driven: you push into ambiguity, learn the domain, and move work forward without needing someone to script your week
• Strong collaborator:
  Engineering, Product, and Marketing teams are excited to work with you. You build trust across functions and communicate design decisions with clarity and conviction
• Extreme ownership mindset: you’re a self-starter who raises the bar through your design craft and doesn’t wait to be told what to do
• Proven ability to make strategic decisions and hold a strong POV on what the product should look and feel like—and the communication skills to get others behind it
• Experience using Figma and Jira as core tools of your workflow
• Experience and genuine excitement about leveraging AI to improve design efficiency and process. At Stash, we use Claude Design and Cursor as part of our design workflow
• (Desirable) Fintech, investing, or other regulated consumer experience: comfort building UX that earns trust and holds up under scrutiny. Subscription product experience is a strong plus
• (Desirable) Design systems and quality at scale: you know how patterns, critique, and consistency help teams move quickly without shipping sloppy work
• (Desirable) AI in the workflow with outcomes: you’ve put AI-assisted design workflows in place in a way that actually changed how software gets delivered—speed, clarity, handoffs, reuse
• (Desirable) Experience owning user research and understanding when it should meaningfully influence the design process — knowing when deeper customer insight is necessary, when rapid iteration is more appropriate, and how to apply research thoughtfully

• Product Design partners with Product, Engineering, Marketing, and Data Science to ship the Stash experience end to end. The team’s job is simple to say and hard to do: make money feel understandable, trustworthy, and actionable for everyday people. Our product’s job is to be a financial advisor in your pocket
• This is a Principal Product Designer role reporting to the VP of Product. You’ll operate as a highly influential individual contributor while helping elevate the broader design organization through mentorship, design leadership, and strong product thinking
• You’ll help set direction for the customer experience, simplify complex problems, and drive quality through reviews, systems thinking, and close partnership with Product and Engineering
• You’ll also help the team work in a modern way, including practical use of AI where it speeds up exploration and delivery, with standards that keep the product coherent and responsible
• Keep design human-centered across the journey: research, flows, copy moments, edge cases. Define what “good” looks like for the customer
• Run the full design arc: pull signal from research, sketch and prototype (using whatever tools make sense, including AI-assisted ones), run tight reviews, hand off specs engineers can build from, and stay involved through launch
• Show up in roadmap and strategy conversations with Product. Contribute a vision and strong point of view on how we get there
• Partner with Engineering, Product, and Marketing so the product feels like one brand
• Help shape how the design team operates: improve critique culture, evolve the design system, encourage reusable patterns, and ensure AI-assisted work still meets a high quality bar
• Mentor and support other designers through feedback, collaboration, systems thinking, and leading by example through your craft
• Say no when something isn’t ready. That includes experiences that need clearer disclosure, better fallbacks, or a simpler path before customers see them
• Strong data-informed product thinking: ability to leverage quantitative data, behavioral insights, experimentation results, and customer signals to inform design decisions, identify opportunities, and continuously improve the user experience
• Help drive faster and more efficient workflows through thoughtful adoption of AI-assisted tooling, rapid prototyping, and modern design practices
• Influence product direction through strong storytelling, strategic thinking, and a clear point of view on customer experience
