Senior Product Designer

About 9fin 9fin is the AI platform powering global debt markets — the world’s largest asset class at over $145 trillion. Debt markets are vast, global, and mission-critical, yet still run on fragmented data, PDFs, and manual workflows. 9fin replaces this broken infrastructure with a single platform that centralises proprietary credit data, deep analysis, and high-value workflows across global markets. Today, 9fin powers teams at 300+ blue-chip institutions worldwide, including global banks, asset managers, private equity firms, law firms, and advisors. The business is scaling at exceptional speed, with rapid expansion in the US and best-in-class retention driven by deep workflow adoption. We’re at a defining inflection point. With proven product-market fit and strong, global market pull, 9fin is accelerating toward becoming the category-defining platform for debt markets worldwide. The Opportunity We’re looking for a Senior Product Designer to help expand the breadth and depth of the 9fin platform. You’ll join a cross-functional product and engineering team solving complex, high-value problems for professionals across global debt markets, spanning AI-powered workflows, financial data and analysis, transaction intelligence, document management, and other emerging product areas. You’ll help shape products used by teams at leading investment banks, asset managers, private equity firms, law firms, and advisory businesses - sophisticated users working with large volumes of complex information, where speed, accuracy, and trust are critical. It’s a chance to shape frontier AI-native products inside a company using technology to transform one of the world’s largest financial markets. What you'll work on Product & Design Strategy Partner with customers, Product Managers, engineers, and subject matter experts to shape product vision and design strategy — not just how it looks, but how it works and why it matters. Synthesise research, feedback, domain expertise, and data to frame clear problems, and translate complex financial workflows into intuitive product experiences. Run discovery to understand what users need, how they work, and where technology can create real value. Align your work to clear outcomes, manage competing priorities, and focus your effort where it has the most impact in high-precision environments. Designing AI-Native Workflows Design interfaces that help users explore, understand, and act on AI-generated insights and complex datasets. Translate model outputs into clear, trustworthy interfaces — with source attribution, confidence, transparency, and appropriate user control. Partner with Product and Engineering on feedback loops and evaluation workflows to improve AI-powered experiences in production. Spot opportunities to apply emerging AI capabilities to real customer problems, prototyping new patterns where no playbook exists yet. Craft & Collaboration Own design end-to-end — flows, wireframes, prototypes, and high-fidelity UI that hold up across edge cases and complex data conditions. Work as an embedded partner to Product, Engineering, Data, and subject matter experts. Communicate design rationale clearly and bring stakeholders along, especially in new or ambiguous territory. Contribute to and evolve the design system to support increasingly sophisticated, data-heavy, AI-driven workflows. About you This role will be a great fit if you are: Comfortable with complexity: you’ve designed for sophisticated users or high-stakes domains (fintech, enterprise SaaS, data platforms, professional tools). Financial markets experience is useful but not required — curiosity matters more. A systems thinker: you shape workflows, behaviours, and trust, not just screens, zooming from the big picture to the finest interaction detail. Focused on trust and precision: you think in edge cases, error states, and ambiguity, especially where AI is involved. AI-native in how you work: generative AI is a natural part of your process, from research to prototyping to stress-testing ideas. A natural prototyper: you find the fastest way to make an idea tangible, whether that’s AI tools, Figma, code, or a pencil sketch. Energised by a blank page: you thrive defining something new and iterating quickly through ambiguity. A strong communicator: you run discovery interviews, facilitate workshops, and know when to challenge, align, or move a team forward. Skilled in your craft: fluent in Figma, comfortable choosing the right fidelity, and experienced contributing to a design system.
