ABOUT CHRONICLE LABS

Chronicle Labs is building infrastructure for testing, evaluating, and operating AI agents.

Our platform captures activity across systems, reconstructs realistic operating environments, and enables teams to replay workflows and validate agent behavior before deployment.

The platform spans event ingestion, data storage and querying, isolated execution environments, backend APIs, developer tooling, and customer-facing applications.

THE ROLE

We are looking for a Senior Platform Engineer with deep Rust experience to help design, build, and operate the systems at the core of Chronicle's platform.

You will work across application architecture, data infrastructure, developer experience, and production operations. The ideal candidate is comfortable moving between designing a reliable service, debugging a concurrency issue, improving a deployment process, and evaluating a new storage architecture.

This is primarily a software engineering role with meaningful production ownership — not a traditional DevOps or infrastructure-only position. You will spend most of your time building backend and distributed systems while also taking responsibility for how those systems are deployed, observed, scaled, and maintained.

WHAT YOU'LL DO

Design and evolve core backend and platform services in Rust.
Build reliable systems for ingesting, processing, storing, querying, and replaying event data.
Develop APIs, streaming services, background jobs, and orchestration systems.
