AI Engineer​/Principal

About Us:

Fifth Dimension is bringing vibe working to document-heavy industries 🌈. 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 🌶️):
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 has witnessed the transformative power of AI and wants to apply it to solve real business problems. You don't just code—you 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 model— it'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.
