AI Solutions Architect (London)

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.

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

• Support pre-sales with technical input when needed (not primary focus)

What we’re looking for

You’ve owned complex enterprise relationships at a VC-backed, start-up SaaS company . You know how to balance multiple demanding customers, keep implementations on track, and maintain technical credibility with both users and executives. You understand that success means customers becoming self-sufficient, not staying dependent on you.

You bring:

• 4+ years of 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

• Exceptional AI/prompting ability — you use AI tools extensively in your work, not just casually

• Comfort being the primary technical face to customer executives

• Ability to make technical trade-off decisions without constant escalation

• Experience translating between customer needs and product requirements

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
