Original job description

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.

ABOUT THE ROLE

As an infrastructure engineer at Aaru, you will build the systems that enable our simulations to run faster, more reliably, and at greater scale. You will work across compute, networking, data pipelines, and developer tooling to remove bottlenecks from Aaru's core engineering and research workflows.

RESPONSIBILITIES

Design and build low-latency, high-throughput infrastructure for large-scale simulations
Improve the reliability and performance of data ingestion and computation pipelines
Identify system bottlenecks across compute, networking, storage, and orchestration
Build tools and abstractions that help engineering and research teams move faster
Productionize experimental research workflows into reliable, repeatable infrastructure
Own infrastructure decisions from architecture through implementation and operation

YOU MAY BE A FIT IF

You have built infrastructure, frameworks, or internal platforms for fast-growing engineering teams
You have deep experience debugging performance and reliability issues in distributed systems
You are comfortable working close to networking, storage, compute, and cloud primitives
You have helped transition research or experimental systems into production
You care about developer experience and build systems that other engineers want to use
You are comfortable with strongly typed languages or languages with algebraic type systems

STRONG CANDIDATES MAY ALSO HAVE

Experience with long-running computational pipelines
Strong knowledge of networking protocols such as HTTP, TLS, TCP, or related systems
Experience designing infrastructure for high-scale data or machine learning workloads
A track record of finding and eliminating bottlenecks in complex systems

LOCATION

This role is based in New York City. Aaru is an in-person company, and the team works in-office five days a week. Candidates are expected to be located within the New York City metropolitan area or open to relocation.

BENEFITS

At Aaru, we take care of our people. In addition to a competitive base salary and equity participation, we offer comprehensive medical, vision, and dental coverage, visa sponsorship and relocation support, and various other benefits and perks.
