The Role
- •As the Backend Engineer, you will build the systems that allow David to think, reason, act, and integrate with the tools businesses rely on.
- •You will work on everything from event-driven architectures and workflow engines to integrations, data models, and performance optimization.
What You'll Build
- •Workflow Execution Engine: Own backend logic for agent task execution, monitoring, and error recovery.
- •Integration Layer: Build and maintain deep integrations with tools such as Gmail, Slack, Linear, Notion, Google Workspace, GitHub, Airtable, and more.
- •Agent Infrastructure: Develop systems that support agent reasoning, planning, state persistence, and long-running task orchestration.
- •Performance & Reliability Layers: Design systems that are scalable, predictable, resilient, and observable.
- •Data & Storage Architecture: Own schema design, event logs, workflow state storage, caching, and audit trails.
What You've Done (Minimum Qualifications)
- •4+ years building backend systems at scale
- •Expert in Python (FastAPI) and async frameworks
