Develop core infrastructure for real-time context ingestion, agent execution, and orchestration in an AI-native revenue operating system.

Responsibilities

  • We are hiring a Foundations Engineer (Deep Infra) to design and operate the systems that power Rox’s agent runtime.
  • This role sits at the intersection of:
  • distributed systems
  • 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.
  • Many of the systems we are building resemble components from:
  • streaming compute systems
  • distributed query engines
  • large-scale event processing pipelines
  • matching and routing infrastructure
  • But with a new constraint: AI agents must operate continuously and reliably in production environments.

Other

  • Rox is building the AI-native revenue operating system.
  • Most enterprise software was built for humans operating dashboards. Rox is built for agents operating systems.
  • Instead of static workflows, Rox runs continuous decision loops powered by real-time context from across the enterprise.
  • Agents analyze signals, reason about them, and take action — automatically.
  • To make that possible, we are building infrastructure that combines elements of:
  • distributed data platforms
  • real-time decision systems
  • agent execution frameworks
  • low-latency context retrieval
  • We’re backed by Sequoia, GV, and General Catalyst and building a small team of engineers who want to work on deep technical systems problems with real-world impact.
  • The Foundations team builds the core infrastructure behind Rox agents.
  • We work on the systems responsible for:
  • real-time context ingestion
  • agent execution and orchestration
  • reliability for long-horizon AI tasks
  • low-latency decisioning across distributed systems
  • If you've worked on systems like:
  • streaming compute platforms
  • distributed query engines
  • real-time OLAP systems
  • matching engines
  • large-scale data infrastructure
  • many of the problems here will feel familiar — but applied to a new category of software.
  • At Rox, agents are constantly:
  • retrieving context
  • making decisions
  • triggering actions
  • updating state
  • The Foundations team builds the infrastructure that makes those loops reliable, fast, and observable.
  • 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.
  • Experience building deep infrastructure systems in production.
  • Examples include:
  • 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.
  • A bias toward shipping systems, learning from production, and improving them continuously.
