AI-Driven Product Designer: B2B FinTech

Medius; Greater London; On-site; GBP 45,000 - 65,000; Full time

Job summary

Medius, a global leader in cloud-based spend management solutions, is seeking a product designer to join a cross-functional squad. You’ll own feature design from problem framing through to shipping and develop your own design voice beyond execution.

You’ll have support from the wider design team, a design system to work from, and clear product direction to operate within. The scope to grow your craft will follow, with a global impact.

Qualifications

• 2+ years of product design experience, ideally in B2B SaaS or fintech.
• Solid UX and UI foundations: you understand the research-to-spec journey and have done it, even if not always independently.
• Proficient in Figma, including components, variants, and auto-layout.
• A genuine interest in AI, both as subject matter (designing AI-powered features) and as a craft tool (using AI to work faster and think more rigorously).
• Clear communicator: able to explain design decisions to engineers and product managers and take feedback constructively.
• A portfolio that shows reasoning, not just finished work

Responsibilities

• Design features end-to-end: taking a problem brief, exploring solutions, building prototypes, and working with engineers through to delivery.
• Contribute to user research and usability testing, building confidence in running sessions and translating findings into design decisions.
• Use AI tools as part of your day-to-day practice, including Figma's AI features and generative prototyping, as standard working method rather than occasional experiment.
• Work closely with a product manager and engineers as a full member of a squad, contributing to decisions beyond the design brief.
• Contribute to the Medius design system: following and improving patterns, flagging gaps, and helping maintain consistency across the product.
• Give and receive design critique in formal crits and async reviews.
