Senior AI/ML Engineer

About RentFlow

We’re the first startup solving a hair-on-fire problem concerning 50%+ of small & medium businesses in the US, right at a moment when the data and infrastructure make it solvable at scale.

At the core of what we’re solving: business rent is fixed, business cash flow isn’t. That gap forces healthy businesses into monthly cash-flow stress and is a major driver of unnecessary business closures.

RentFlow turns fixed business rent into a cash-flow-synced product, underwriting it in real time from transaction-level data. This opens a $15B+ rent-splitting market and lets us expand into an 'AI CFO' cash-flow intelligence product for business owners and the platforms around them (e.g., property management platforms, franchises, lenders, landlords…).

We’re a seed-stage company, live since May 2025, growing ~3x MoM, and ramping up early partnerships with fast-growing SMB fintechs and major property platforms.

Early-Stage Opportunity

We’re hiring our first Senior AI Engineer to own underwriting, cash-flow intelligence, and data insights end-to-end.

This is a foundational role. You’ll design and ship models that make real financial decisions in production, affecting how and when thousands of business owners pay rent each month. You’ll work directly with the founders and have meaningful ownership over both technical direction and business outcomes.

What You’ll Do

• Model messy, real-world SMB cash flows from transaction-level data
• Build and iterate on underwriting & decisioning systems
• Turn raw financial data into clear, actionable insights for business owners and partners
• Design signals that balance risk, growth, and user trust in real time
• Collaborate closely with founders on product, risk, and roadmap decisions
• Help shape the long-term architecture of RentFlow’s AI & data stack
• If you have full-stack experience, help translate financial insights into clear, user-facing dashboards and interfaces

You’ll Be a Great Fit If You

• Have built and shipped ML or data-driven systems in production
• Are comfortable working with imperfect, noisy financial data
• Think in terms of decisions, not just models
• Care about real-world impact
• Enjoy high ownership, fast iteration, and ambiguous problem spaces
• Want to help define the technical DNA of an early-stage company
• Are excited to be an early hire with outsized impact, real equity, and real leverage on product and company direction

Why This Role Is Different

• Your models directly control real money and real outcomes
• You’ll help define an entirely new category at the intersection of rent, finance, and AI
• You’ll work side-by-side with founders
• You’ll have meaningful equity and real leverage from day one

If you want to build something with real stakes, real users, and real impact as an early hire, we’d love to talk!
