I'm Sierra Biddulph, a designer with 3 years experience designing for enterprise SaaS, AI, and mobility. I specialize in translating complex, regulated systems into interfaces users can trust and understand.
I'm excited to bring this perspective to Capital One as an Product Design Senior Associate, making financial ecosystems seamless & accessible for everyone.
Previously, I have:
Built trust in high-stakes, regulated environments
As a product designer building apps to remotely control trains in a rail yard, I make designs that meet strict regulations and communicate disclaimers to users while making sure they complete safety due diligence.
Translated complex data into actionable interfaces
I designed for a rail traffic control interface that help yard managers make sense of large datasets. Users can understand complex operational data at a glance and make edits at both the macro and micro level
Contributed to enterprise design systems at scale
At IBM, I worked within enterprise design systems to create a onboarding pattern which increased user retention by +50%.
Championed inclusive, accessible design
I've designed for diverse user groups, including a project for blind and low vision users. I led design and research, conducting studies with 400+ participants where we developed a new usability testing method for blind users that involves them earlier in the design process, creating a 95% usability testing score for our design system.
