## About the Role

* Typically 2 - 10 years of experience in infrastructure, platform or backend engineering, with senior or staff-level ownership and technical depth.
 * At least 1 year at a fast-growing startup with fewer than approximately 150 employees, ideally pre-Series C, or at a high-bar developer tools or product company. Founder and YC startup experience count.
 * Deep production database experience spanning schema design, scaling and performance tuning.
 * Daily use of AI coding tools, with the ability to explain a practical workflow using tools such as Claude Code, Cursor or background agents.
 * A clear record of shipping, strong autonomy, urgency, excellent communication and increasing scope of responsibility. Evidence may include launches, meaningful GitHub contributions, open-source work or technical writing.

Nice to have

 * Infrastructure for AI agents or ML workloads, including long-running jobs, model routing, inference or GPU orchestration.
 * Experience with Kubernetes, AWS and the Hercules stack: TypeScript, React and Postgres.

## Description

* Design and evolve systems for long-running AI agents, durable workflows and multi-tenant application hosting.
 * Build and operate workflow orchestration using Temporal or a comparable production system; design robust recovery for partial failures.
 * Manage cloud infrastructure as code using CDK or Terraform, and orchestrate fleets of servers or containers.
 * Design, scale and tune production databases; the platform uses Postgres, Redis and ClickHouse.
 * Partner with the founders to drive ambiguous technical goals through architecture, implementation, production launch and ongoing improvement.
 * Use AI coding tools daily to accelerate delivery while maintaining a high bar for technical quality.

Mandatory requirements / dealbreakers

 * End-to-end ownership: Has owned and shipped an entire product module, such as authentication/access management, CMS, email, files or billing; experience must extend beyond small features and bug fixes.
 * Production workflow orchestration: Hands-on experience with Temporal or a comparable durable workflow orchestrator, such as Cadence or AWS Step Functions.
 * Infrastructure as code and fleet operations: Manages infrastructure in CDK or Terraform and has orchestrated servers or containers, for example Kubernetes or Docker on AWS.
