We're looking for a collaborative, detail-oriented Senior Product Designer who's passionate about crafting intuitive, user-centred experiences and comfortable owning design decisions with minimal oversight. You'll play a leading role in designing innovative products that balance user needs with business goals, taking ownership of key areas of our design system and setting the standard for consistency across our product suite.

As a thoughtful problem solver, you'll work independently and cross-functionally — partnering with product managers, engineers, marketing, and compliance — to translate ambiguous or evolving requirements into elegant design solutions, and to help shape those requirements in the first place. You'll use data, user insights, and testing to inform your work, mentor and give feedback to other designers, and proactively QA builds while iterating based on feedback.

This is a hands-on senior role in a fast-paced environment where strong communication, ownership, sound judgement under ambiguity, and a deep empathy for users are essential. If you're excited about shaping impactful digital experiences, elevating design quality across a growing product suite, and refining design from concept to execution, we'd love to hear from you.
