Agent-native operating systems for modern institutions.

Brain Co. builds end-to-end agentic workflows for enterprises and governments: underwriting and claims in insurance, permitting and licensing in government, prior authorization in health. The company started with proven components, fits them to existing workflows, and deploys in weeks. Many of the products are the first of their kind.

Brain Co. in their own words.

How it started

From coffee to company.

“Why aren’t the biggest institutions implementing cutting-edge AI?” Jared Kushner put that question to Elad Gil over coffee in February 2024, at Elad’s office in Dogpatch.

Kushner and his business partner Luis Videgaray had spent months with leaders of large institutions and kept meeting the same gap: those leaders knew they needed an AI strategy, but had no route to the talent who could deliver one. In Silicon Valley the opposite held, with the best AI talent moving fast and little access to the institutions where the work would matter most. Gil’s answer was to build the company that bridged the two.

As told by Eric Wu, Opendoor co-founder and one of Brain Co.’s incubators

01 · What Brain Co. builds

One operating system per institution.

Each product takes the everyday work of an institution, the parts that still run on forms, queues and review, and rebuilds it as an agentic workflow fitted to that organisation’s own data and outcomes.

GovOS

Permitting, licensing, procurement

The everyday work of local government, fitted to each authority’s data, workflows and outcomes.

InsuranceOS

Underwriting and claims

Underwriting, claims, authorization, and the operations that sit underneath the policy.

HealthOS

Prior auth, denials, intake

The work between a patient and their care, built for clinical and regulatory constraints.

FinanceOS

Reporting and reconciliation

Every number traced back to its source, auditable down to the line item.

Atlas

The platform underneath

Sovereign-grade security, no model lock-in. Every operating system is built on it.

The team

Engineers from the hardest systems

Built by engineers out of Coinbase, Twitter, Pinterest, Rippling, Anduril and Plaid, across San Francisco, New York, Abu Dhabi, Doha and Jordan.

02 · Open roles

What they’re hiring for.

Applied ML Engineer is the focus right now, open across junior, mid and senior, with product and platform engineering alongside it.

Applied ML

Applied Machine Learning Engineer

SF / New York / Abu Dhabi / Doha / Jordan · Junior to senior
Building and deploying ML against business and product problems, rather than pure research or infrastructure.
  • Core ML fundamentals, not AI engineering alone. You think rigorously about evals and probabilistic systems.
  • A bachelor’s in CS is the floor; an advanced degree is common on the team but not required.
  • Open across seniority, roughly a third junior, a third mid, a third senior. New grads have been hired and done well.
  • Motivated, takes pride in the work, comfortable in a startup.

The process

How the interview runs.

Applied ML

Two screens, then onsite

An ML screen and a coding screen, then an onsite: an ML round, an AI coding round on a representative ML problem where every AI tool is fair game, and a deep-dive on past work with a manager.

Software engineering

Coding, design, then onsite

A coding round and a design round, then an onsite covering coding, design, AI coding and past projects.
