Senior Backend Infrastructure Engineer

About The Position

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.

Requirements

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

Responsibilities

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
Own critical systems end-to-end and make decisions that affect the reliability and velocity of the entire engineering team.
