The Role

We're looking for an infrastructure engineer to build the platform that powers our AI agents. Your customers are other engineers on the team; you'll create the systems, tools, and abstractions that make everyone more productive and our platform more reliable.

This isn't DevOps or traditional SRE. You'll write application code, but focused on the foundational layers: deployment systems, observability, data infrastructure, and the internal tools that let the team move fast without breaking things.

What You'll Work On

A few examples from our current priorities:

• Controlled deployments: Staged rollout systems with traffic scaling, scheduling, and pass rate thresholds to safeguard production

• Observability: Creating the instrumentation, logging, and monitoring infrastructure that helps us understand what's happening in production

• Data infrastructure: Building pipelines and storage systems for training data, analytics, and agent memory

• Developer tooling: Internal CLIs, testing frameworks, and automation that reduces friction for the engineering team

As a senior infrastructure engineer, you'll own critical systems end-to-end and make decisions that affect the reliability and velocity of the entire engineering team.

Tech Stack

• Backend: Python (Django/FastAPI), TypeScript (Node.js)

• Infrastructure: AWS, Modal, Kubernetes

• Data: ClickHouse, PostgreSQL, Redis

• Tooling: Terraform, Docker, CI/CD pipelines

You Might Be a Fit If You

• Have 4+ years of experience in infrastructure, platform, or backend engineering roles

• Have built systems that other engineers depend on, and understand the responsibility that comes with that

• Care deeply about reliability, but also know when "good enough" is the right call

• Are comfortable across the stack, from application code to cloud infrastructure

• Can debug production issues under pressure and build systems that prevent them from recurring

• Think about developer experience as a product—you want the tools you build to be a pleasure to use

• Are excited about the infrastructure challenges of running AI agents at scale
