As Applied Research Engineer, you'll own the depth of our knowledge and retrieval infrastructure - ontology design, hybrid retrieval (dense/sparse/structured), information extraction, and knowledge quality systems. You'll translate research into production and shape the technical direction of a core system from day one.

Every time two companies in the physical economy need to exchange data, someone builds a custom integration by hand. Analysts, engineers, QA. All manual. Every time. Google "EDI" if you haven't. It's wild.
We built AI agents that do the whole thing: gather requirements in plain English, write the integration code, test it, deploy it, fix it when it breaks.
We have paying enterprise customers and more demand than we can keep up with.
You'd be the first engineering hire. Agent orchestration, durable execution runtime, self-healing infra, most of the important architectural decisions haven't been made yet.
The founders built a logistics startup from pre-seed to 400+ people. We've been dealing with broken integrations for years.
TypeScript, Effect-TS, Bun, PostgreSQL, K8s, AWS. Paid work day. Under 2 weeks to offer.
