Chief of Staff (Generalist)

Build is the AI-native operating partner for institutional real estate, a new kind of firm built from the ground up around agentic AI. Where traditional firms sell advice, reports and hours, Build delivers outcomes: verified, expert-level work produced a magnitude faster than market. We pair domain professionals with AI agents to do the work itself, not just assist with it.

In the past year, Build has worked alongside Fortune 500 companies, governments and the world's largest alternative asset investors on hyperscale projects across digital infrastructure, energy, industrial and more.

We're backed by tier 1 investors, one of the co-founders of OpenAI and Meta AI Research, and angels from Blackstone, Palantir, OpenAI and Google DeepMind.

We're looking for a Chief of Staff, the single hire that multiplies the CEO's time the most.

This is for a high-performing, senior REPE or institutional developer operator who wants a serious challenge. Someone who can hold the internal standard when the CEO isn't in the room, and represent Build externally with the same credibility he does.

You should be energised by the space between commercial leadership, product judgement and company building: closing deals with institutional customers, translating real workflows into product, running the operating cadence, and building the muscle that takes Build from founder-led to function-led without losing speed.

You'll own real customer and company outcomes, and help define what great operating leadership looks like at an AI-native company in the built world.

• Hold the internal standard across GTM, product and ops

• Lead customer conversations, run diligence and close commercial deals with institutional real estate teams

• Partner with product and engineering to translate real workflows into product

• Represent Build externally to customers, investors, partners and the broader real estate and AI ecosystem

• Build and run the company's operating cadence: planning, reviews, hiring loops, board updates, internal comms

• Identify the highest-leverage problem each week and either own it or stand up an owner

• Drive special projects end to end: new market expansion, partnerships, GTM playbooks, senior hires

• Build the operating system of the company alongside the CEO

• Owning the close of a flagship deal with a top-tier REPE customer: running diligence, shaping the commercial structure, getting the contract signed

• Standing up the GTM motion: outbound playbook, qualification framework, pipeline review

• Sitting in customer workflow sessions, identifying the highest-impact product gaps and driving them through to shipped features

• Running the planning cycle: translating strategy into quarterly priorities, weekly commitments and clear ownership

• Leading a senior hire end to end: sourcing, screening, closing and setting the bar for future hires in that function

• You have 4-8 years in REPE or as an institutional developer

• You've closed deals or delivered projects in an operating capacity

• You have an operator temperament and a bias toward execution

• You're NYC-based, or willing to be

• You move fast, hold a high bar and own outcomes through to completion

• You're energised by ambiguity and want to build the operating system of a company

• You care about AI, software and the future of the built world

• Experience selling, structuring or closing software or services into institutional real estate

• Experience as a founder, GM or early operator at a high-growth startup

• Existing relationships across REPE, institutional development, infrastructure or energy

• Experience standing up GTM motions, partnership programmes or operating cadences from scratch
