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.

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, Canada or UK.

What you bring:

* 4+ years of experience designing B2B digital products and systems, with a strong portfolio showcasing your process, breadth of work, and impact. * Proven ability to collaborate cross-functionally and great communication skills: you present design decisions and processes clearly and confidently, regardless of the audience. * Strong verbal and visual presentation skills with an articulate point of view on design decisions. * A divergent exploratory process and ability to think iteratively, leaning on experimentation and rapid prototyping to explore solutions and validate ideas quickly, and ability to communicate trade-offs effectively. * Proficiency in Figma and experience building and maintaining design systems. * Enthusiasm for exploring AI tools like v0 or Cursor to augment your design and research workflow Nice to have:

* Background in fintech, SaaS, or payments—understanding of security, compliance, and complex flows is a plus.
* Experience designing for Product-Led Growth (PLG), including growth funnels, self-serve journeys, and onboarding experiences (consumer or B2B)
* Experience unifying multiple products or platforms under a cohesive design system, driving consistency and scalability across experiences.
* Experience with developer-facing products, particularly in the API, SDK, or platform-as-a-product space.
* Experience conducting user research and usability testing, with a proven ability to translate findings into actionable designs.
* Familiarity with service design techniques (e.g., journey mapping, service blueprints) and the ability to think about product design within the context of service design.
