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. We’re looking for our first Product Designer in London, reporting directly to the founder/CPO. You’ll be a founding member of a new product team alongside engineering.
You won’t inherit a design system or a Figma library. You’ll create them. You’ll define how intelligence is presented, how trust is built, how complex workflows feel simple, and how AI and humans collaborate in professional decision-making. This is an IC role with founding scope. If you’re the kind of designer who could lead a team but wants to spend the next two years honing their craft on genuinely novel problems, this is the role.
We’re a London, New York, and Singapore based startup with ample runway, backed by Tier 1 European and American investors. Our founders, Johnny Morris and Dr. Kate Jarvis bring a powerful blend of expertise: Johnny has 17+ years applying data and analytics to Real Estate, while Kate holds a Stanford PhD and 12 years of executive experience across Silicon Valley and London startups. At Fifth Dimension, we’re demanding yet encouraging, valuing experimentation and kind challenges. Our company values, Own It, Ship It, and Don’t Be Boring, drive us to deliver exceptional results while fostering a culture of innovation and continuous improvement.
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? The design problems here are genuinely novel.
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.
- Define the language. Establish the visual standards, interaction patterns, component systems, and design principles the product grows into.
- Invent AI-native interaction. Write the playbook for trust, explainability, and responsive agentic UI.
- Talk to customers. Visit offices, observe how they work, run usability sessions.
- Design to drive growth. Your design decisions should guide onboarding flows and expanding use cases.
- Shape what gets built. You’ll influence product direction with the CPO and engineering.
- Raise the bar. Help engineers develop stronger design instincts and champion frontend quality.
About You: You’re a designer who ships. Exceptional taste, fast hands, strong opinions. You’re comfortable in Figma and on customer calls. You’ve designed complex, data-rich interfaces for demanding professional users. You know what it means to design something 200 people use for 8 hours a day. You use AI tools to amplify your output and you’re excited about what that means for the craft of design.
What We’re Looking For:
- Deep experience in product design, with a portfolio that shows real taste and craft in complex information design.
- Shipped data-rich interfaces in production.
- Runs your own user research: interviews, usability tests, site visits.
- Systems thinker, designs in components and patterns.
- Proficient with AI tools in their own workflow.
- At least one startup or early-stage experience where they owned design end-to-end.
- Experience designing AI interfaces, trust signals, agentic workflows.
Nice to Have:
- Has been a founding or sole designer before.
- Former founder, built businesses.
- Adjacent domain knowledge, financial services, legal tech, data platforms.
- Visible in the design community.
- Can touch code, enough to prototype or unblock themselves.
Compensation: We are a hybrid London office; everyone comes in every Wednesday, ideally more. Base: GBP 90,000-120,000. Meaningful equity on a standard vesting schedule.
Benefits: Enhanced pension contributions, 5%; Unlimited annual leave; GBP 100 monthly wellbeing budget; Tailored support for exceptional challenges; Enhanced parental leave; Electric car scheme; GBP 1,000 annual training budget; 2 week all-company December shutdown.
The Process: Submit your CV and portfolio, with answers to a few questions; A call with our CPO; A portfolio review and design discussion; A live design challenge using a real Fifth Dimension problem; An in-person session with people across the business.
