About this role

Our Engineering organization owns the software that makes our marketplace work. Our Engineering Platform group enables product engineering teams to build and operate software with unmatched speed and quality. The Code Authoring team owns the developer environment at Faire: the AI coding tools engineers use every day, remote development environments, and the sandboxes our end-to-end tests run in. We care about developer experience, the quality of code written by people and agents, the reliability of the tools engineers depend on, and the cost of running those tools.

The team focuses on the following areas and capabilities:

• AI code authoring harnesses

• Cloud environments for running agents on Claude and Cursor

• Validation of agent-written code: CI checks, pre-push checks, and automated review

• Agent memory and context management

• Model selection and LLM cost per pull request

• Remote development environments

• Sandboxes for end-to-end testing and agent runs

• Pre-push validation speed

• Tracing and cost visibility for every agent run

• Uptime and SLAs for developer tooling

• Developer cloud infrastructure cost across AWS and OCI

• Integrations with Linear and GitHub

The team also evaluates AI coding tools and owns our relationships with those vendors.

We're looking for: An experienced technical leader with substantial backend architecture and developer tooling experience to work alongside our team, develop and deliver on a technical roadmap for how code gets written and shipped at Faire, and engage with engineering teams organization-wide.

What you'll do

• Own the architecture of the systems that run coding agents against our codebase: the service that turns tickets into pull requests, the sandboxes and remote development environments it runs in, and the integrations with Linear, GitHub, Claude, and Cursor. You decide how these pieces fit together and hold the long-term design.

• Own the developer workflow end to end: how an engineer or an agent gets from a ticket to a merged, tested change. Know where it is slow or fragile, and change the tooling to fix it.

• Run these systems as production infrast
