Senior Product Designer

At Xelix, we work with some of the world's largest companies to automate and strengthen their financial controls. Our AI solutions redefine how Accounts Payable teams operate - moving from manual processes to automated, intelligent workflows.

Xelix is a fast-paced scale-up - things move fast and expectations are high. We raised our Series B with Insight Partners in June 2025 and are expanding aggressively, whilst remaining profitable. We have over 100 talented people pulling together to achieve our goals. Everyone is trusted to take ownership, move fast and have a meaningful impact. We prioritise personal and professional growth, keep things fun & we love to celebrate a milestone together.

In this role you'll grow, be challenged and help shape the future of Xelix. If you're excited about building something special with us, we'd love to hear from you.

Xelix sits at the intersection of finance and AI - dense data, high-stakes workflows, expert users. As a Senior Product Designer, you'll be at the centre of that complexity, working on problems that don't come with a playbook.

You’ll sit in a trio with your Product Manager and Tech Lead rather than designing against a brief handed down to you. We're AI-native by culture as well as by product, so we want you experimenting with AI in your own process, not just watching from the sidelines.

Given the scope of this role, we're looking for someone who can get up to speed with the product and how we work quickly.

Take end-to-end ownership of high-complexity, high-ambiguity work - often involving dense B2B data with no obvious precedent. Frame the problem yourself when there's no clean brief to start from.

Work alongside your PM and Tech Lead on roadmap and product strategy, not just execution. Spot gaps and risks before they're handed to you. Push back on scope or approach when the product needs it.

Bring a real point of view on how AI is changing design and engineering, and put it into practice - in your prototyping, your workflow, and your thinking about what's now possible.

Plan and run usability testing yourself, and turn findings into direction. Hold the standard for usability, accessibility, and consistency - including in critique. Own parts of the design system as the product scales.

We care more about mindset and craft than ticking every box. If you meet most, but not all, of this - we'd still love to hear from you.

• 5+ years in product design, with a portfolio showing complex, high-quality B2B work shipped end-to-end.

• A track record of taking ambiguous problems to shipped solutions independently.

• Real experience planning and leading research and usability testing, not just joining it.

• Genuine comfort using AI-assisted design and development tools as part of your actual workflow.

• Deep Figma proficiency and systems-level thinking about components and scalability.

• Strong grasp of accessibility (WCAG), responsive design, and design systems architecture.

• Solid understanding of HTML/CSS/JS and how design decisions land in code.

• Comfort with ambiguity - you bring structure, rather than wait for it to arrive.

• Excellent communication, and sound judgment on when to elevate versus decide.

• Understanding of finance or accounting basics.

• Experience in fast-moving environments (scale-up, start-up).

• Experience mentoring designers or contributing to team process.
