AI Solutions Engineer

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.

About us

What you'll do

As a Solutions Engineer, you'll implement and optimize AI automation for enterprise customers across the US.

Day to day:

• Implement and optimize - Build customer prompt libraries and skills using proven patterns; structure data and context for AI consumption; iterate based on performance
• Define evaluations - Build Evals, analyze results for failure patterns, identify root causes (prompt issues, data structure problems, context gaps
• Surface patterns and gaps - Document what's novel across implementations; escalate product limitations with context and customer impact
• Drive feature adoption - Translate new platform capabilities into customer value through training content and implementation plans
• Technical triage - Debug customer issues systematically; resolve directly when possible, escalate with full diagnostic context when needed
• Maintain and improve - Keep prompt libraries optimized as platform evolves; update data structures when customer needs change

What we're looking for

You've implemented AI solutions in production and know how to optimize for quality. You design effective prompts, structure data for AI consumption, and run evaluations to measure what's working. When things break or underperform, you troubleshoot systematically.

You bring:

• 1-3 years hands-on with AI/LLMs - you've built prompt templates, automated workflows with AI tools, or helped customers implement AI features in production
• Organized data for AI - you've structured spreadsheets, built taxonomies, or created knowledge bases that AI systems can actually parse and use effectively
• Tested systematically - you've compared outputs across different prompts, tracked what works vs what doesn't, A/B tested approaches to improve results
• Delivered to customers - you've helped customers set up workflows, trained teams on AI tools, or solved implementation problems with measurable success
• Debugged AI outputs - when results were wrong, you figured out why (prompt needed fixing, data was messy, context was missing) and corrected it
• Built from patterns - you noticed what worked across cases, created templates or playbooks, and reused proven approaches rather than starting from scratch each time
• NYC-based or willing to relocate

Bonus points:

• Real estate, financial services, or legal industry exposure
• Created templates/documentation that others used successfully
• Basic coding ability (Python, JavaScript) for scripting
• Experience at AI-first companies in customer-facing roles

What we offer

We're building something extraordinary and we want extraordinary people. Our benefits package goes beyond the standard startup offering - from tailored support for life's challenges (IVF, gender-affirming care, ADHD diagnosis, and more), to meaningful parental leave.

• $130K-$165K base salary (depending on experience)
• Meaningful equity (standard vesting)
• 2% company-sponsored 401(k)
• Company healthcare, dental, life insurance
• Unlimited PTO
• $100 monthly wellbeing budget
• Tailored support for exceptional challenges (gender-affirming care, specialist medical, ADHD/Autism diagnosis, IVF, therapy)
• Enhanced parental leave (14 weeks full pay for primary caregiver, 6 weeks for secondary)
• $1000 annual training budget
