AI Solutions Engineer

Fifth Dimension is ushering in a golden age of work, where boring tasks are automated away, the right data are always at your fingertips, and maximal creativity is encouraged.

We’re an early stage start-up with ample runway, backed by leading European and American investors.

The founders, Johnny Morris and Dr. Kate Jarvis, are both data nerds. But that's not all. Johnny’s got 16 years’ experience in Real Estate, our GTM niche. Kate’s got a PhD in Linguistics from Stanford plus 12 years’ CPTOing across Silicon Valley and London startups. We're demanding, excitable, encouraging of experimentation, adoring of bad puns, and have built our business on a foundation of compassion and kind challenge.

Join our New York team as a Solutions Engineer building AI automation for billion-dollar real estate firms.

A week in the life of our NYC Solutions Engineer

Monday : Implementing a lease extraction skill for Starwood, helping them adapt proven patterns to their specific data definitions. You spot an edge case that we don’t yet support and request a feature update.

Tuesday : Running evaluations on three customer implementations. One's underperforming - you analyze failure patterns, identify it's a context window issue with their documents, escalate with diagnostic details and propose prompt restructuring.

Wednesday : Engineering shipped external knowledge base integration. You're building training content, tailoring to accounts which need this capability first, designing rollout plans tailored to their data structures.

Thursday : A customer's data dictionary produces inconsistent extractions. You recognize this pattern from another account - their schema needs restructuring. You apply the fix, document both cases, and update the customer with the good news.

Friday : Building prompt libraries for two new accounts ahead of onboarding. You're adapting proven patterns but notice their document hierarchy requires a different context organization approach - you capture this insight and agree an approach with the team.

This is hands-on AI implementation at Fifth Dimension. Optimizing with customers daily. Learning what works. Making our platform better through systematic pattern recognition.
