Principal Product Designer. Brand and Experience (Contract, Hands-On)

OfferUp • Bellevue, WA

38d • $100 - $165

About The Position

OfferUp is seeking a senior, hands-on Product Designer to help shape the brand and experience of their evolving platform. This role focuses on translating OfferUp's brand strategy into practical product-experience principles and designing key user experiences. The designer will work from concept through engineering-ready hand-off, developing testable hypotheses, and partnering with UX Design and Consumer Product teams. The goal is to determine if distinctive experience design can create measurable value for OfferUp, leaving behind improved product experiences and a more durable way of producing them. This is an individual-contributor role, requiring hands-on design work rather than direction-setting or oversight only.

Requirements

• Significant experience designing beloved consumer mobile products at scale.
• A portfolio showing both strong interaction design and sophisticated visual judgment.
• Demonstrated ability to translate a brand or product strategy into an end-to-end digital experience.
• Experience improving discovery, marketplace, commerce, social, community or local products.
• Fluency in experimentation, behavioral metrics and qualitative research.
• Experience creating or evolving product design systems.
• The executive communication skills to influence senior Product and business leaders.
• Comfort entering an established product with meaningful legacy behavior, technical constraints and deeply monitored performance metrics.
• Experience acting as a Principal Designer, Design Director, Head of Product Design or equivalent hands-on design leader.

Responsibilities

• Translate OfferUp's brand strategy into practical product-experience principles, and design the frameworks and artifacts that make those principles usable by product and engineering.
• Identify the highest-value opportunities to make the product more comprehensible, locally relevant, trustworthy and recognizably OfferUp.
• Design a small number of strategically important user experiences in Figma from concept through engineering-ready hand-off.
• Develop testable hypotheses connecting design decisions to user and business outcomes, and build the prototypes needed to test them.
• Partner closely with UX Design and Consumer Product teams to prototype, validate, ship and measure the work — hands-on for the core design deliverables, not delegating execution.
• Build reusable interaction, visual and content patterns — component-level design work — that strengthen the broader product design system.
• Assess the design operating model and recommend the appropriate long-term capability, informed by direct hands-on experience building within the current structure.

Benefits

• Compensation is structured as an hourly contract rate to reflect the fractional, non-benefits-eligible nature of this role.
• This role is not eligible for health benefits, paid time off, retirement contributions, bonus, commission, or equity.
