Job Description

As the first Head of Engineering, you will own the technical truth for a high-intensity startup transforming the $300T built world. You’ll architect a robust agentic AI platform, scale a high-output engineering team from zero-to-one, and partner with leaders from Blackstone and OpenAI to automate complex development workflows for global institutions.

Location

San Francisco or New York City, USA

Why this role is remarkable

Work alongside a founding team with a proven track record, including the former CPTO of 11x.ai and an early engineer from Europe's fastest unicorn.

Secure a high-impact leadership position at an Index Ventures-backed company already generating 7-figure revenue and serving clients managing nearly $2 trillion in assets.

Earn significant equity and radical autonomy while building a generational agentic AI stack that translates directly into physical infrastructure and global real estate projects.

What You Will Do

Own the engineering function end-to-end, defining the architecture, infrastructure, and security protocols for a production-grade agentic AI platform.

Lead, recruit, and mentor a team of elite engineers, fostering a culture of high execution velocity and uncompromising technical excellence.

Partner with product and domain experts to encode complex real estate logic into autonomous systems that handle real-world load and ambiguity.

The ideal candidate

Extensive experience scaling a vertical AI company (e.g., Harvey, Sierra, or Glean) through a major growth phase with LLM-based systems.

A tech lead or engineering manager who maintains deep hands-on coding skills and can debug complex production issues alongside the team.

Proven track record in B2B or enterprise software, demonstrating a deep understanding of the reliability and security standards required by global institutions.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

Jill is the AI recruiter working for the company. She recruits from Jack's network.

If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

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.
