Morgan, Rothschild & Co, Aviva Investors, Visible Alpha, Revolut).

We are seeking a talented and passionate Senior Product Designer to join their growing team and help shape the future of AI design principles as they continue to push the boundaries of AI in Finance.

The Role

As the sole Senior IC Product Designer, working in close partnership with Finster's Head of Experience, you will play a crucial role in shaping the user experience of an innovative AI-powered financial research platform. The ideal candidate has strong product sense, excellent problem-solving abilities, and a proven track record in crafting delightful and intuitive designs that address real user needs in complex, data-heavy environments. This is an exciting opportunity to contribute to a fast-paced environment, own key product areas end to end, and make a significant impact on the product's success.

What you'll do:

• Shape the UX of Finster AI's AI-powered financial research platform, designing interfaces that make complex data and workflows context-aware, timely, intuitive, and trustworthy.
• Collaborate with product owners, engineers, and other stakeholders to translate product requirements into user flows, wireframes, and high-fidelity designs for a complex, data-heavy web application.
• Iterate on designs based on feedback, user data, and technical constraints, balancing usability, clarity, and feasibility.
• Maintain and evolve the design system to ensure consistency, scalability, and efficiency across all products.
• Use AI tools to increase design velocity and exploration — without replacing critical thinking.
• Champion user-centered design principles throughout the product development lifecycle.
• Contribute to a collaborative and creative team environment.

Who You Are

• Proven experience in product design (3+ years), with a portfolio showcasing your design process and strong visual design skills.
• Proficiency in design and prototyping tools (Figma).
• Experience maintaining design systems, including components, patterns, and documentation.
• Solid understanding of user-centered design principles, information architecture, and usability best practices.
• Familiarity with accessibility standards and a commitment to building inclusive, usable interfaces.
• Web experience is required (the product is web-based, though a mobile app is planned).
• Comfortable using AI tools in your design workflow (designing AI products is a plus, but not a prerequisite).
• Clever, creative, and curious about the implementation of AI in a highly-regulated and high-risk industry.
• Strong problem-solving skills for complex, data-heavy applications, with a keen attention to detail.
• Data- and UX-driven approach to decision making.
• Ability to articulate design decisions and rationale effectively to designers, engineers, and business stakeholders.
• Excellent communication and collaboration skills.
• Self-motivated and able to manage priorities in a fast-paced environment.

Nice-to-haves

• Interest or experience in AI/ML-driven interfaces (e.g., conversational UIs, recommendation systems, data visualisation for AI outputs).
• Interest or background in fintech, financial services, or personal finance tools.
• Familiarity with agile development methodologies and collaborating in sprint-based workflows.
• Experience with user research methodologies and data analysis (e.g., planning and synthesizing user interviews or usability tests).
• Understanding of regulatory or compliance-driven design considerations in finance (e.g., clarity, trust, data transparency).

You Will Thrive Here if You

• Are comfortable being challenged and feel at home with ambiguity and rapid change.
• Enjoy working in an entrepreneurial, fast-paced environment where priorities can shift and new opportunities emerge quickly.
• Can work autonomously and own key product areas end to end.
• Are highly collaborative and an effective communicator.
