Company Description

BUILD, Inc. is a seed-stage venture creating the agentic AI stack for institutional real estate, backed by Index Ventures and c-suite leaders from OpenAI and Blackstone. Already generating 7-figure revenue, the team is automating complex development and acquisitions workflows 90% faster than traditional human processes for trillion-dollar asset managers.

Job Description

You will own end-to-end agentic workflows, from prototype to production, building visual reasoning and multi-agent systems that solve real-world problems. Partnering with domain experts and institutional customers, you’ll translate complex real estate tasks into high-performance software, driving the next generation of automation for the built world’s most significant projects.

Location

San Francisco, USA

Why this role is remarkable

• Work at the frontier of agentic AI with a team including leadership experience from 11x.ai’s rapid scale-up and backing from heavyweights like Index Ventures.
• Experience radical autonomy and high-stakes ownership in a seed-stage startup that has already achieved 7-figure revenue and is rapidly approaching 8-figures.
• Solve hard, unsolved problems where AI meets the physical world, directly impacting massive global infrastructure, energy, and industrial projects through autonomous workflows.

What You Will Do

• Design, build, and deploy production-grade AI agents using Python and LangGraph to handle complex, long-running real estate development workflows.
• Own and ship full-stack features end-to-end, managing everything from backend agent reasoning logic to polished, high-utility frontend user surfaces.
• Collaborate directly with institutional customers to translate multi-week manual processes into automated outcomes that scale across trillion-dollar asset portfolios.

The ideal candidate

• Has 3-5 years of engineering experience, ideally within high-growth vertical AI companies or elite engineering cultures like Ramp, Scale AI, or Glean.
• Demonstrates a proven track record of shipping production-grade LLM or agentic systems that deliver measurable value to real-world end users.
• Possesses full-stack capabilities with a strong "startup DNA," excelling in fast-moving, ambiguous environments where they can drive projects from concept to completion.

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.
