Head of Infrastructure

About the role

Aaru builds simulations of human behavior. Each simulation contains a population of agents, each representing a person who could plausibly exist in the real world and capable of making decisions within a modeled environment. Companies and institutions use these simulations to test consequential choices before committing—from product launches and policy changes to critical communications. Because the agents are simulated rather than recruited, they can reason through complex hypotheticals without fatigue or the response effects common in human studies.

Responsibilities

• Own all compute, orchestration, data, and serving infrastructure for our simulations.
• Design the systems that run millions of concurrent agents efficiently.
• Set the infrastructure roadmap: cost, reliability, scale, and iteration speed.
• Build and lead the Infrastructure team.
• Hire its first dedicated members.
• Own reliability and incident response, and keep the on-call load humane.
• Treat cloud spend as a first-class product constraint, and drive it down.
• Partner with research and platform so new capabilities reach customers fast.

Requirements

You built and operated large-scale distributed systems: schedulers, inference fleets, data pipelines, or similar.

You made a large system dramatically cheaper or faster, and you can show the numbers.

You have led engineers before, and you still write code every week.

You make one-way-door decisions carefully and two-way-door decisions fast.

You want to build in person, in New York, at high speed.

Strong candidates may also have Experience with GPU fleets, ML inference at scale, or agentic workloads.

Experience at the founding stage of an infrastructure function.

Open-source work in the infrastructure space.

Qualifications

Commensurate with experience.
