Head of Infrastructure

# Head of InfrastructureTechnical StaffInfrastructureNYC$450K – $750K • Offers Equity## **ABOUT AARU**Aaru operates at the frontier of predictive intelligence, using AI to simulate and predict human behavior at scale. By generating and deploying instances of artificial intelligence that mirror humans, called agents, Aaru simulates entire populations with unprecedented accuracy. Our partners use Aaru to refine strategic positioning, identify and understand high-value audiences, validate concepts and messaging before launch, optimize pricing decisions, and build a continuously richer understanding of their customers through simulation. We provide organizations with invaluable foresight, empowering them to anticipate outcomes and proactively make the right decisions at the right time, every time.We're a small, dedicated, mission-driven team and we intend to stay that way. We believe the best work happens when exceptionally talented people are given ownership, trust and the space to operate without bureaucratic friction. We work with urgency and intellectual honesty and expect new team members to match our velocity. We seek individuals who thrive at the frontier, who push beyond conventional limits, who bring curiosity and conviction in equal measure, and who want their work to have demonstrable impact in the world. If you're energized by the idea of a small team doing things that feel impossible, let’s build together. **The role**At Aaru, infrastructure sets the limits of the product. A simulation may contain hundreds of thousands of agents, each consuming compute, maintaining state, and making decisions. They must run quickly and cheaply enough that customers can test another scenario while the answer still matters. Every improvement in speed, scale, or cost expands what Aaru can simulate and what customers can use it for.You will own this system end to end and report directly to the founders. You will set the technical direction, build the infrastructure team, and remain an active engineer: designing core systems and writing production code.## **What you will do*** 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.## **You might be a good fit if*** 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.Questions about the role?
