Senior Pre-Sales Engineer

About Fifth Dimension

Fifth Dimension is an AI-native enterprise software company transforming how the world’s largest real estate investment managers work. We automate complex document workflows, extract structured intelligence from unstructured data, and give professionals an AI workspace that replaces manual processes with 98% accuracy, where horizontal AI tools deliver 60 to 70%. We are a global company with offices in London, New York, and Singapore, backed by top-tier American and European investors. Our values are Own It, Ship It, and Don’t Be Boring. We are demanding and encouraging in equal measure. We experiment, we challenge each other, and we ship daily.

What you’ll do

• Lead technical discovery and scoping with prospects, translating their requirements into solution architecture and implementation plans that close deals
• Build and run live demos with prospect-specific data, making the technical case so compelling that procurement becomes a formality
• Own RFP/RFI responses and security questionnaires: the technical collateral that gets deals through procurement
• Build the pre-sales playbook, demo environments, battle cards, and competitive positioning from humble beginnings
• Partner with AEs to prioritize pipeline, coach on technical positioning, and ensure every high-value conversation has technical depth
• Bridge won deals to the implementation team with clean handoffs and scoped requirements
• Carry the voice of prospect technical requirements into Product and Engineering, shaping the roadmap with deal intelligence
• Unite long-term product vision from the founders with daily deal implementation and sales
• Travel 25 to 30% to prospect and client sites across the US

What we’re looking for

• You sell to CTOs. You walk into a room and earn technical credibility in the first 5 minutes. Your pre-sales work closes deals.
• You discuss what differentiates 5D from marketplace competitors (horizontal and vertical) with ease. You know how to go toe-to-toe with CTOs on LLMs, RAG, security architecture, and data pipelines. No prep sheet required.
• You build and run live demos with their actual data.
• You’ve navigated $250k+ deals through procurement, legal, and multi-stakeholder sign-off.
• You move fast. You build your own decks, prep your own calls, and don’t wait for enablement teams or materials that don’t exist yet.
• While we’ve had solutions engineers help out with pre and post sales, you’re building out the pre sales function as one of the first in the role. There’s no set playbook, the demo library is spotty, and everyone’s wearing 1000 hats. You thrive in that chaos.
• Track record of shortening sales cycles.

Bonus points

• You’ve been the first or founding pre-sales / SE hire at a startup
• Real estate, financial services, or professional services domain knowledge
• Coding ability (Python, SQL) to build custom demo environments and proof-of-value scripts
• Experience at an AI-native or data platform company

What we offer

• Compensation: $170,000 to $220,000 base + variable (up to $290,000 OTE) depending on experience
• Equity: Meaningful, on a standard vesting schedule
• 401(k): 2% company-sponsored contributions
• Healthcare: Company-sponsored medical, dental, and life insurance
• PTO: Unlimited
• Wellbeing: $100 monthly budget
• Tailored support: Contributions to gender-affirming care, private specialist and scans, ADHD/autism diagnosis, IVF, and therapy
• Parental leave: 14 weeks full pay (primary caregiver), six weeks full pay (secondary caregiver)
• Training: $1,000 annual budget

Why this role

• This one asks you to build it.
• You will be the first senior pre-sales hire in NYC selling $250,000 to $400,000 ACV deals to marquee enterprise customers. You will work shoulder-to-shoulder with the founders on the highest-value deals. You will set the standard for everyone who follows.
• The product sells itself when demoed well. 98% accuracy on lease abstraction, where ChatGPT delivers 65%, is not a talking point; it’s a live demonstration that silences a room. Your job is to put that demonstration in front of every CTO who matters.
• We are a Series A company with offices in London, New York, and Singapore, working with the firms that finance and manage the built world. That's every skyscraper, data centre, wind farm, and bridge - in the $393 trillion real assets market. We help them drive alpha, close faster, and make better calls. We ship daily, building a product that compounds: every data source, every skill, every customer correction makes the platform more powerful than the last.
• Johnny and Kate founded 5D from a shared frustration. Johnny spent 17 years inside institutional real estate, close enough to the problem to know exactly where the pain was. Kate spent 12 years building enterprise software, close enough to know what it would take to fix it. They started 5D because no one else was doing it right, and they still run it that way: demanding, direct, and genuinely excited about what they're building.
• The decisions 5D powers shape cities, funds, and careers. We are direct with each other, high on craft, and genuinely invested in each other winning, and we build better for it. If that's the kind of place you want to spend your time, let's talk.
