AI Solutions Architect (London)
Be the reason why our customers love us, work directly with founders to transform how America's largest real estate firms make billion-dollar decisions with AI.
Join our London team as the technical architect behind how billion-dollar real estate firms adopt AI.
A week in the life of our London Solutions Architect
Monday: Deep in a discovery session with a leading UK real estate investor. They want to automate their entire lease abstraction process. You’re mapping their workflow, identifying edge cases, and scoping what’s achievable.
Tuesday: Building. You’re creating a skill pack for a UK-listed REIT’s rent roll analysis, testing against their sample documents, iterating on prompts until the output is bulletproof.
Wednesday: QA session on a skill the team built. You’re reviewing outputs against gold data, documenting edge cases, preparing the adoption playbook before customer handover.
Thursday: Training session with our CSM team. Walking them through the skill pack you delivered, answering questions, watching them run it independently.
Friday: Product feedback day. You’re writing up insights from the week’s customer interactions, drafting a feature request with clear ROI. Engineering shipped a feature, you’re testing it before customers see it.
This is solutions architecture at Fifth Dimension. You own the technical relationship. Customers trust you. Product listens to you. Revenue depends on you.
About us
Fifth Dimension is bringing the magic of AI automation to document-heavy industries 🌈. Today we work with leading real estate businesses in the UK and US, automating complex workflows, extracting valuable insights from documents, and empowering professionals to focus on high-impact work. Our AI workspace transforms how large investment managers handle leases, development documents, and investment decisions.
We’re an international startup based in London and New York, backed by Tier 1 American and European investors. Our founders, Johnny Morris and Dr. Kate Jarvis, bring a powerful blend of expertise: Johnny has 18+ 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 thoughtful challenge. Our company values — Own It, Ship It, and Don’t Be Boring — drive us to deliver exceptional results whilst fostering a culture of innovation and continuous improvement.
What you’ll do
As our Solutions Architect in London, you’ll own the technical relationship for our enterprise customers in the UK.
Day to day, you will:
Lead customer discovery sessions to decompose business processes into technical requirements
Build skill packs, workflows, and platform extensions using our AI tools
Quality assure all deliverables before customer handover
Create adoption playbooks to train customers to self-sufficiency
Translate new features into customer value, design skills that maximize adoption
Be the voice of customers to Product and Engineering — write feature requests with clear ROI, advocate for customer needs, influence roadmap priorities

What we’re looking for
You’ve owned complex enterprise relationships at a SaaS company. You know how to balance multiple demanding customers, keep implementations on track, and maintain technical credibility with both users and executives.

You bring:
Experience as a Technical Account Manager, Solutions Architect, or Senior Customer Engineer at an enterprise SaaS company
Track record managing complex customer relationships simultaneously with strong project management discipline

Bonus points if you have:
Real estate, financial services, or legal industry knowledge
Experience at a high-growth startup where you wore multiple hats
Previous experience working closely with C-suite executives
Comfort working across US/international teams and time zones
