About The Position

Ornn is building the financial infrastructure for AI compute. Our price indices are live on Bloomberg Terminal. We structure and trade compute hedging instruments. And we're now building a platform that brings exchange-grade mechanics like order management, matching, scheduling, and settlement to how compute capacity gets reserved and allocated. We're a lean team in New York, backed by leading venture and strategic investors. About the Role You would be one of the first engineers building a system where bugs have financial consequences. The platform handles real capacity commitments backed by real contracts, so the engineering bar is closer to a trading system than a typical SaaS product. You will work across the full stack having ownership on the infrastructure and user experience for both AI labs and neoclouds. You will work directly with our Head of Engineering. Expect real influence over architecture and technical direction, building end-to-end.

Requirements

1+ years shipping production software.
Strong Python skillset: you've built backend services, APIs, and data-intensive systems with it.
Full-stack capability.
Comfortable operating independently in a lean team.
BS, MS in CS or related field from a strong program.

Nice To Haves

Rust experience, especially for systems-level or performance-critical work.
Time in trading, fintech, or crypto where latency and reliability were non-negotiable.
Familiarity with GPU compute, cloud infrastructure, or datacenter operations.
Experience with IaC, container orchestration, and CI/CD in production.

Responsibilities

Build core platform features that let people use and trade compute.
Own frontend interfaces for thousands of customers (and growing!)
Make reliability a feature: write tests, maintain code quality, and treat correctness as a hard requirement.
Shape technical decisions around performance as the platform scales.
Contribute to infrastructure and deployment tooling as Ornn grows.
