## About the Role

* distributed data platforms
 * streaming compute systems
 * real-time analytics infrastructure
 * distributed query engines
 * high-scale backend services

Strong intuition for latency, reliability, and scalability tradeoffs.

Experience operating systems where real-world traffic exposes edge cases quickly.

Comfort debugging complex distributed systems in production.

## Description

We are hiring a Foundations Engineer (Deep Infra) to design and operate the systems that power Rox's agent runtime., * real-time data infrastructure

 * agent orchestration
 * decisioning systems

You will work on infrastructure similar to what powers large-scale data platforms - but optimized for continuous AI decision loops rather than batch analytics.

But with a new constraint: AI agents must operate continuously and reliably in production environments.

What You'll Do

 * Design and build core distributed systems powering Rox agents.
 * Build infrastructure for real-time context ingestion and retrieval.
 * Develop systems that enable low-latency agent decisioning at scale.
 * Improve reliability, observability, and fault tolerance across agent infrastructure.
 * Build execution frameworks that support long-running agent workflows.
 * Collaborate closely with product engineers and forward deployed engineers to translate infrastructure capabilities into customer impact.
 * Ship production systems quickly and evolve them based on real-world usage.
