Product Designer in London

About us

At Jigsaw, we’re on a mission to transform the way professional services and financial institutions work. We do this by helping our clients organise, visualise and use their data (think Figma or Canva but for the ‘City’). Our clients include the world’s biggest consultancies, leading financial institutions and top law firms. Jigsaw was founded by two seasoned entrepreneurs, Stephen and Travis. This is their second venture together; their first was acquired by a US private equity firm and went on to become a billion-dollar company and a household name in professional service firms across the world. Jigsaw is now on a growth trajectory few Series A companies achieve - putting us in the top quartile SaaS companies globally. Today we proudly serve thousands of users from nearly two hundred businesses worldwide, who love our products and use them every day. But we’re only getting started! We have ambitious goals and we’re looking for talented people to help us achieve them.

Why join us? We're not about the corporate grind; instead, we thrive on creativity, enthusiasm, and a touch of humour to make magic happen. We hire people with high ownership and a bias for action. Then we trust and empower them to do their best work.

The roles

We're hiring across two areas of the product: our Data Viz platform (complex data, backend tooling, API and integration UX where we're starting almost from scratch) and our plugin suite (designing within Microsoft environments, constrained surfaces, driving adoption with lawyers and accountants who are mid-workflow when they reach you). These two positions won't be just optimisation focused, tweaking button states or iterating on flows someone else conceived. You'll be shaping products end-to-end, from the first discovery interview to the shipped experience whilst being part of a team that moves fast, operates with real ownership, and genuinely values the craft of design. Whilst there's ambiguity here, there's also the rare chance to put your name on work that actually matters.

You’ll get to…

• Design interfaces that help users work with complex, interconnected data. Think entity hierarchies, ownership chains, multi-level relationships - where the detail and the big picture both need to be present at once.
• Solve interaction challenges unique to constrained surfaces: limited screen space, unfamiliar entry points, users who are mid-workflow when they arrive.
• Work through end-to-end product journeys, from data ingest and API integration to plugin installation, onboarding, and daily use, with a knack for spotting where users drop off or get stuck.
• Run discovery with real users, including lawyers, accountants and compliance professionals to understand where the current product loses them and what they actually need.
• Be the design thinking advocate in a team that's deeply technical and passionate about data, but not always thinking about the human on the other end.
• Work closely with product and engineering to make decisions that hold up technically, not just in Figma.
• Contribute to and evolve Jigsaw's design system. The patterns you create become the building blocks others build on.

You’ll thrive in this role if...

• You have 4+ years of product design experience in SaaS and a portfolio that shows your thinking, not just polished screens.
• You can make dense, complex information feel manageable - knowing when to show, when to hide, and how to guide someone's eye.
• You’re comfortable designing within constraints and see them as a creative challenge rather than a blocker.
• You have strong problem-solving skills and can translate a user need into a clear, considered design solution.
• You’re proficient in Figma or equivalent prototyping tools, with a solid understanding of accessibility and UX best practices.
• You’re comfortable presenting to clients, running discovery sessions, and gathering requirements.
• You enjoy figuring things out when the answer isn't clear, rather than waiting for clarity that may never fully arrive.

Nice to have (not dealbreakers)

• Experience with data visualisation, API-adjacent products, or backend tooling.
• Familiarity designing integrations, extensions, or embedded tools within a host environment (e.g. Microsoft 365).
• Some exposure to legal, finance, compliance or designing for a specialised domain.
• Experience contributing to or maturing a design system.
