Fifth Dimension is bringing vibe working to document-heavy industries đ. Today we work with real estate businesses in the US, EU and APAC, automating complex tasks, extracting valuable insights from documents, and empowering professionals to focus on high-impact work. Our AI workspace transforms how large investment managers and developers handle leases, development documents, and investment decisions.
We're a London and New York based startup with an ample runway, backed by Tier 1 European and American investors. Our founders, Johnny Morris and Dr. Kate Jarvis bring a powerful blend of expertise (and spice đśď¸): 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.
It's 9 AM on a Monday. Using Claude Code, you've just implemented a new extraction pipeline that transforms how property leases are analyzed. By noon, a major real estate firm emails: "This just saved us 40 hours of work." By Thursday, you're troubleshooting with their development team as they integrate your APIs into their enterprise document management system. By Friday, you're celebrating with the team as data flows seamlessly between platforms, unlocking new capabilities for real estate investors that will help them make faster, more informed decisions across their portfolios.
You're an expert software engineer who's witnessed the transformative power of AI and wants to apply it to solve real business problems. You don't just codeâyou architect solutions that make users say "How did we ever work without this?"
You've developed exceptional engineering and architectural skills through years of practice. You stay current with AI advances and can identify the right approach for each unique challenge. Your experience implementing AI in business contexts has taught you that the magic isn't in the modelâit's in understanding the problem deeply.
You're proficient with AI coding assistance tools like Claude Code, leveraging them to accelerate development and focus on higher-level architectural challenges. You understand that modern engineering means effectively collaborating with AI to maximise your productivity and creative potential.
Details don't escape you. You're comfortable diving into complex documents and intricate code to build a complete picture. As someone who thrives in fast-paced environments, you adapt quickly and mentor other engineers while collaborating effectively with commercial teams and customers.
You're passionate about your personal growth and see each complex problem as an opportunity to expand your capabilities. You actively seek challenges that push the boundaries of what's possible and value environments where you can both contribute your expertise and continue to evolve as an engineer.
Reporting to our CTO Chen, you'll architect and implement innovative AI technology to meet our enterprise customers' unique needs. Working closely with our skilled engineering team, you'll design scalable AI solutions that deliver tangible value and expand the capabilities of our generative AI platform. You'll own the complete lifecycle of core product capabilities from initial customer conversations through architecture, implementation, deployment, and customer adoption.
At 5D, we embody three core principles: Own it, Ship it, and Don't be boring.
Our engineering team values:
Here's an example of how we work: Early in our journey with AI, one of our engineers discovered that certain words like "concise" or "creative" had disproportionate effects on model outputsâwe called them "demon words." Rather than accepting this as an immutable quirk, they spent a week methodically tracking down every instance in our codebase, testing alternatives, and documenting the patterns they found. This intellectual curiosity to understand the "why" behind technical oddities, combined with the honesty to admit what we didn't yet understand, led to significant improvements in our product's reliability. At 5D, we value this combination of curiosity and honesty above allâthe willingness to dive deep into unexpected behaviors and openly share both successes and failures with the team.
We're building something extraordinary and we want extraordinary people. Our benefits package goes beyond the standard startup offeringâfrom tailored support for life's challenges (IVF, gender-affirming care, ADHD diagnosis, and more), to meaningful parental leave.

Fifth Dimension is a technology company dedicated to bringing AI to the real estate industry. Our AI-Powered Operating System is revolutionising workflows across the RE value chain, helping professionals focus on high-impact activities while our AI handles the document-heavy, time-consuming tasks.
Whether you're already experimenting with AI or just at beginning of your journey, weâd love to chat about how 5D can bring substantial value to your business.
