Build partners with Index to accelerate institutional development with AI. Learn More

AI for the Built World:
Build has created the agentic AI stack for institutional real estate, automating complex development and acquisitions workflows 90% faster than humans to accelerate the world's most important built projects - digital infrastructure, energy, industrial - from concept to completion.

Our mission is to accelerate and amplify the world's most important built projects - inventing a better way to build through a collaboration between human experts and agentic AI. We envision a future where the world's buildings are driven from concept to completion, autonomously. Without delays, cost, and complexity. Enabling people to deliver a magnitude more deals. To make decisions, build relationships and create.

To start, we're partnering with the world's biggest built world institutions from $T alternative assets investors, prolific developers and even governments to push the frontier of what's possible. We're backed by c-suite from Blackstone and OpenAI alongside the world's best venture capital firms.

Join us in shaping the future of the Built World and exponentially accelerate your career in the process. We welcome you to do your life's work here.

This role absorbs the operational load from Build's leadership. You job is to intercept everything that lands on an executive's plate (logistics, coordination, or the operational machinery underneath) and consumes time.

What you will do

• Run the day-to-day operations of the office across London and New York
• Manage scheduling, logistics, and travel without supervision
• Handle inbound communications and route or resolve what does not need the principal's attention
• Keep the team informed of executive priorities and ensure nothing gets lost in translation between leadership and the people executing
• Coordinate across the team on time-sensitive operational tasks so executives are not pulled in
• Prepare briefings, context, and materials for meetings that matter
• Handle commercial, financial and personal information with complete discretion
• Manage the systems that make the operation self-running rather than constantly managed

Who we are looking for

Someone who has operated inside a busy, senior environment and understands that the job is keeping things moving without being asked. You are calm under pressure, good with people at every level of an organisation, and comfortable holding a lot of context without making it visible.

Based in New York and/or London as required.
