The Opportunity

Fifth Dimension is the most prominent AI company in real estate in the world, bringing the magic of AI automation to document-heavy industries. Our AI workspace helps leading investment managers, owners, and operators across the US, UK, and APAC automate complex workflows, extract insights from critical documents, and make faster, smarter decisions.

The Challenge

We're leaving a huge amount of value uncaptured because we haven't yet taken a design-led view of the product. What should the product look like to immediately communicate intelligence and connectivity? How do the first 30 seconds of a sales demo show we're an intelligence platform, not a chatbot? What's the UI that makes users want to share their work and pull their colleagues in?

What You'll Do

Design and ship. You own the design layer end-to-end. User research through to pixel-perfect delivery. There is no handoff. You'll work shoulder-to-shoulder with engineering in London, prototype rapidly, and use AI tools to collapse the gap between idea and implementation. We ship daily. You will too.

Define the language. You'll establish the visual standards, interaction patterns, component systems, and design principles the product grows into. Typography, hierarchy, density, motion, data visualisation. You set the bar and hold it.

Invent AI-native interaction. Agentic workflows, streaming outputs, document intelligence, confidence signals, human-AI collaboration. There's no playbook for this. You'll be writing it. Trust, explainability, responsive agentic UI, designing intelligence. These are the problems that will define your best work.

Talk to customers. Visit their offices. Watch them work. Run usability sessions. Sit with a portfolio manager and understand how they think about a $500M real estate portfolio. There is no research team. You are the research team.

Design to drive growth. The first 30 seconds of a demo, the onboarding flow that lands a new team, the interface that makes a customer expand from one use case to five. Your design decisions directly drive revenue. You'll see that in the numbers, not just the Figma comments.

Shape what gets built. You won't just execute on someone else's vision. You'll influence what the product becomes, not just how it looks. The best design work here is upstream, shaping product direction alongside the CPO and engineering.

Raise the bar. Help product engineers develop stronger design instincts. Champion frontend quality, accessibility, and the details that separate good products from great ones. Make everyone care more about craft.

About You

You're a designer who ships. Exceptional taste, fast hands, strong opinions. You're equally comfortable in Figma and on a customer call. You don't wait for permission and you don't need months of discovery to produce something tangible. People around you would say you operate at a level above your title.

You've designed complex, data-rich interfaces for demanding professional users. Tables, dashboards, document viewers, multi-step workflows. You know what it means to design something 200 people use for 8 hours a day. Real enterprise tools, not consumer apps, not marketing sites.

You use AI tools to amplify your output and you're excited about what that means for the craft of design. You've designed AI interfaces: trust signals, agentic workflows, streaming UIs, human-AI collaboration. In production or as a side project, you've been exploring by building.

You have sharp product instinct. You shape what gets built, not just how it looks. You make trade-offs, back them up, and run your own user research. You don't need a research team to understand your users.

You thrive with autonomy. Ambiguity doesn't scare you, it's where the interesting work lives. You're energised by early-stage: building something from zero, not inheriting a playbook.

Deep experience in product design, with a portfolio that shows real taste and craft in complex information design

Proficient with AI tools in their own workflow, uses them to move faster, not as a novelty

At least one startup or early-stage experience where they owned design end-to-end

Nice to Have

Former founder, built businesses, wants to build product without the CEO overhead

Adjacent domain knowledge, financial services, legal tech, data platforms

Visible in the design community, writes, speaks, shares work publicly

Can touch code, enough to prototype or unblock themselves
