About this role

At Stash, the Principal Product Designer helps everyday Americans invest and build wealth by making financial products understandable, trustworthy, and actionable. The role focuses on democratizing wealth creation through education, advice, and tools that deliver greater financial freedom while leveraging AI to solve meaningful customer problems.

You will run the full design arc from research and prototyping to handoff and launch, keeping work human-centered across flows, copy, and edge cases. Strong data-informed thinking guides decisions using quantitative data, behavioral insights, and experimentation results to improve the experience continuously.

Reporting to the VP of Product, you operate as a highly influential individual contributor who partners closely with Product, Engineering, and Marketing. The work includes setting direction for the customer experience, simplifying complex problems, and driving quality through reviews, systems thinking, and modern AI-assisted practices that keep the product coherent.

You will elevate the broader design organization through mentorship, critique culture, and reusable patterns while influencing roadmap and strategy conversations with a clear point of view. This player-coach approach helps the team ship faster without sacrificing the high quality bar customers expect.

Requirements

8+ years of experience in a fast-paced D2C product design environment.
Strong principal-level IC craft with deep hands-on credibility in the details and the ability to lead through influence.
Player-coach mindset that naturally mentors and elevates other designers through collaboration, feedback, and example-setting.
Senior product design leadership with strong end-to-end product sense, systems thinking, and a track record shipping great work with Product and Engineering.
Intellectually curious and self-driven, able to push into ambiguity, learn the domain, and move work forward without needing direction.
Strong data-informed product thinking that leverages quantitative data, behavioral insights, experimentation results, and customer signals.

Responsibilities

Keep design human-centered across the journey by defining what good looks like for research, flows, copy, and edge cases.
Run the full design arc from pulling signal in research to sketching, prototyping, running reviews, and handing off specs engineers can build from.
Show up in roadmap and strategy conversations with Product and contribute a vision on how to get there.
Partner with Engineering, Product, and Marketing so the product feels like one brand across every touchpoint.
Help shape how the design team operates by improving critique culture, evolving the design system, and ensuring AI-assisted work meets a high quality bar.
Mentor and support other designers through feedback, collaboration, systems thinking, and leading by example through craft.
Say no when something is not ready, including experiences that need clearer disclosure, better fallbacks, or a simpler path.
Influence product direction through strong storytelling, strategic thinking, and a clear point of view on customer experience.
