What you'll work on
- Agent architecture and orchestration across hundreds of concurrent CI runs
- Multi-model routing across Anthropic and OpenAI, picking the right model per task
- The log ingestion pipeline (ClickHouse, billions lines of log ingested per week) that powers agent investigations
- Sandboxed execution, where each agent gets a full dev environment
- New agents (custom automations, security workflows, performance analyses) and the framework they share
- The GitHub App, Slack, and the integrations layer pulling signal from infrastructure (Datadog, Sentry, GCP, AWS, etc…)
Requirements
- Builder mindset. You've shipped real products, not just features. You've made hard tradeoffs with incomplete information and lived with the consequences.
- AI-native workflow. You actively use AI coding agents every day. You understand prompt engineering, context management, and running multiple agent instances in parallel.
- Taste over volume. We care more about architecture decisions, system design, and technical judgment than lines of code.
- CII/CD and infrastructure fluency. Real experience with GitHub Actions, CI pipelines, containers, and cloud infrastructure.
- High agency. You enjoy a high level of autonomy and know how to use it.
