Company Description

Index Ventures-backed agentic AI startup automating institutional real estate workflows

Job Description

You will design and deploy production-grade AI agents for the world’s largest real estate institutions. As an early engineer, you'll own end-to-end product workflows that automate complex acquisitions and development tasks. This role sits at the intersection of long-running agents and physical-world impact, scaling a platform already generating 7-figure revenue.

Location

Why this role is remarkable

• Join a high-velocity team backed by Index Ventures and C-suite leaders from Blackstone and OpenAI with a clear path to 8-figure revenue.
• Work at the frontier of agentic AI, building systems that reason over complex documents and visual data to accelerate massive global infrastructure projects.
• Gain a "founder's track" experience with radical autonomy and significant equity, learning to build a generational company from zero alongside elite 11x.ai alumni.
  
  

What You Will Do

• Design, build, and deploy production-grade AI agents using Python, LangGraph, and modern LLM frameworks to automate high-stakes real estate workflows.
• Partner directly with domain experts and trillion-dollar asset managers to translate manual processes into autonomous, long-running agentic systems.
• Ship full-stack features end-to-end, taking full ownership of reliability, context engineering, and the technical outcomes of your code in production.
  
  

The ideal candidate

• Has 3-5 years of engineering experience, ideally at elite vertical AI or high-growth startups like Harvey, Scale AI, or Ramp.
• Demonstrates proven experience shipping production-grade LLM-based systems or agents that solve non-trivial, multi-step reasoning problems for real users.
• Possesses a full-stack engineering toolkit with a strong ownership mindset, capable of navigating ambiguity and moving with extreme velocity in a startup environment.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
