Senior Product Designer - Financial Crimes

Own high-stakes decision systems and design for complex, multi-stakeholder ecosystems. Balance risk detection, operational efficiency, and customer impact while ensuring clarity and fairness in the design process.

Responsibilities

• Own high-stakes decision systems
• Design for complex, multi-stakeholder ecosystems, supporting internal teams like investigators and strategists as well as external partners such as banks and regulators with efficient, configurable, and high-quality tools
• Balance risk detection, operational efficiency, and customer impact in systems where false positives and false negatives both carry real costs
• Build a deep understanding of the technical and policy foundations behind how Mercury detects unusual activity, applies rules or thresholds, and decides when human review or action is required
• Design for judgement, not just automation
• Own the end-to-end design process: scoping projects, defining workflows, designing detailed interactions and visuals, and ensuring quality implementation
• Craft designs from first principles, anticipating edge cases and failure modes to ensure resilience in high-stakes contexts
• Prototype multiple UX and visual concepts, then refine toward the right solution
• Ground decisions in real-world insights
• Conduct deep, contextual research with investigators, strategists, and cross-functional partners to uncover hidden work, manual workarounds, and operational pain points
• Test designs with real users to validate comprehension, confidence, and decision quality in complex scenarios
• Use research insights to shape product direction and system design, and inform team understanding and product direction
• Shape alignment across teams through collaboration & influence
• Partner closely with product, engineering, and investigations to contribute to strategy and roadmap
• Drive alignment by crafting narratives and prototypes that bring clarity across audiences - from engineers to executives
• Contribute to scalable design patterns that advance user outcomes and business goals
• Improve consistency, speed, and confidence as Mercury grows

Requirements

• 7+ years of product design experience, with ownership of end-to-end projects in complex or ambiguous problem spaces
• Enjoy both interaction design and systems thinking, especially building for multi-user, multi-modal, multi-step workflows that remain clear and usable under real-world constraints and edge cases
• Are comfortable designing alongside data-driven or automated systems and integrating AI or ML models into your products, including understanding how uncertainty, confidence, and human review should be represented in the interface
• Use prototyping as a core thinking tool to explore tradeoffs, test assumptions, and align cross-functional partners
• Have experience in data-heavy, regulated, or operationally complex domains (fintech, trust & safety, healthcare, security, or similar), or are motivated to deeply learn one
• Can translate complex technical or policy constraints into understandable, intuitive interfaces
• Ground your design decisions in contextual research and usability testing, and know how to turn messy, qualitative insight into concrete product direction with measurable impact
• Thrive in multi-stakeholder environments and can navigate disagreement with clarity, empathy, and a bias toward taking action
• Understand the balance between rigor and momentum, and know when to push for quality versus when to ship and iterate
• Value collaboration, humility, and shared ownership, especially when working alongside peers at different career levels, and on high-stakes problems with no perfect answers
