Founding Engineer, Applied Research

What you’ll do

We’re solving applied research problems in clinical intelligence. Backbone’s core systems, based on post-trained open-weights models and systems of closed-weights models, read charts, claims, denials, appeals, clinical criteria, payer policies, and quality metrics, then make accurate, defensible decisions in production. We also leverage continually improving browser-use and computer-use models to navigate payer portals, EHRs, practice management systems, and the messy software layer that healthcare runs on.

This is not a pure research role. Alongside core model improvements, you’ll take ambiguous research problems, turn them into evals, improve model behavior, and work with engineers to put those improvements into production.

You will

• Build evals for clinical reasoning, chart understanding, claims review, authorization logic, denial analysis, appeal generation, and payer policy interpretation
