Senior Data Engineer

As a Senior Data Engineer, you'll sit at the forefront of this new platform. This isn't a maintenance role on an established system - you'll be deeply involved in shaping the product itself: the pipeline architecture agents build on, the semantic layer that gives data meaning, and the standards for what "agent-ready data" means.You'll build the infrastructure that lets agents autonomously create pipelines - ingesting, cleaning, and unifying data from a wide range of sources, then connecting it to a semantic model and ontology so it's fast, queryable, and meaningful for both AI agents and traditional BI workloads. What you'll do Build the pipeline infrastructure and primitives that agents use to autonomously ingest, clean, and merge data from diverse sourcesShape the semantic model and ontology layer that turns raw company data into agent-ready dataDesign and operate robust DAG-based orchestration for reliable, observable, agent-driven workflowsMake large volumes of data performant and accessible for agents and analytical/BI workloads alikeWork closely with product and AI engineering to define what agents need from data infrastructureHelp set the engineering standards and best practices as the team grows

Milo is an AI analyst that gives teams answers from their data in minutes. No more waiting days for a dashboard or chasing down the one person who knows where the numbers live - Milo connects to your company's data and delivers insight on demand. Building the agent was just the beginning. We're now moving one level deeper: a data platform built by agents, for agents. On our platform, agents create pipelines that automatically clean a company's data and make it agent-ready by connecting it to a semantic model and an ontology. The result: clean, well-defined, meaning-rich data that any agent - ours or anyone else's - can reliably reason over. We believe this is the next foundational layer of the AI stack, and we're building it now.
