Senior Product Designer

We’re looking for a Senior Product Designer to join our Product team and craft an engaging experience across a complex set of payments products and features. This role involves leading end-to-end design efforts for technical B2B workflows, collaborating cross-functionally, and crafting intuitive, high-impact product experiences that balance usability, business outcomes, and technical feasibility. This will span both greenfield design (building new experiences from the ground up) and redesign work on existing Payment Gateway products. You’ll work closely with product managers, engineers, and other stakeholders to identify opportunities, deeply understand user needs, and translate insights into scalable design solutions. This role is well-suited for someone who thrives in ambiguity, is eager to bring strategic design thinking to product challenges, and wants to grow their influence in a dynamic environment. This role can be based in the US or Canada.
