Develop and maintain Sift’s MCP server, the tool surface that lets both our agents and our customers’ AI tools query telemetry directly
Work across the whole stack
Build the frontend surfaces where Sift Agents live, and make them feel great
Design and implement the APIs that power our agentic capabilities
Run agents reliably at scale, both in the cloud and on-prem
