About Us

At Rox, we believe in empowering people to do their best work.

Our platform supercharges sellers with autonomous revenue agents to do the manual work so they can focus on what they do best: selling. Just as coding agents 10x’d engineering, revenue agents 10x customer work.

We are reimagining the revenue stack by building the world’s first revenue operating system, from the application layer to the system of context. With Rox, humans are evolving to orchestrators while agents manage the end-to-end customer lifecycle.

Rox powers Global 2000 leaders in banking, hardware, construction, and sovereign AI, while serving dominant AI winners like Ramp and Cognition.

Underlying all of this success is an unwavering, shared belief in the mission, with an unreasonable commitment of doing whatever it takes to make it a reality.

The Team

Nothing is possible without the world-class team, assembled to redefine how businesses operate.

Members on our team have:

• Founded and exited successful companies

• Held the highest positions at Google, AWS, Confluent, and New Relic

• Won IMO and IOI gold medals

• Published field-defining papers

We’re backed by the best, including Sequoia, General Catalyst, Google Ventures, Elad Gil, and Chris Ré.

Core Principles

Taste: Craft beautiful experiences.

No matter how small, we strive to make sure every detail is right. We care deeply about every interaction, both in terms of whether it helps the seller get the job done, but also how the product makes them feel. We get a visceral feeling when something is off and stop at nothing to make sure we make it right. We never settle, continuously exploring ways to delight sellers.

Obsession: Commit unreasonably.

In all aspects of our craft, we commit. We not only are immediately reactive to customers’ requests but are proactive about driving value even before they ask. We are also obsessive about always learning and honing our craft, improving ourselves and product every single day.

Action: Get it done.

Talking is easy but the difference comes from the execution. We lean heavily towards making thoughtful yet fast decisions and delivering immediately. We play in a field where trust is paramount. We earn the trust and right to empower the best sellers by forging a history of over-delivering on the promise at record speed.

Your Role

About the Foundations Team

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.

The Role

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.

Responsibilities

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.

Qualifications

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.
