Software Engineer, Frontend

Midstream Health

About The Position

Midstream is an AI-native financial operating system for health systems, founded by experienced entrepreneurs and backed by top-tier investors. We give finance, supply chain, and managed care teams real-time visibility into where margin is at risk, with a precise action plan for capturing it before it's gone. Purpose-built for healthcare's complexity, Midstream transforms structured, unstructured, and external data into instant, contract-aware insights that drive smarter decisions. Our AI agents unify spend and revenue operations across the full back-office, learning and adapting with every interaction and delivering always-on intelligence that no point solution or one-off engagement can match. We're compressing months to minutes and turning post-period hindsight into in-the-moment foresight. The tempo of healthcare finance is changing, and Midstream is leading it. Opportunity We are looking for a Software Engineer, Front End to design and build the interaction layer for Midstream’s AI-native product. This role focuses on how users understand, decide, and act within the product. You will translate complex data and AI-driven responses into clear, intuitive experiences that guide users toward the right decisions rather than just present information. You’ll work across the stack, with a primary focus on frontend, to build fast, responsive interfaces that make complex workflows and decisions feel simple and reliable. This is an opportunity to help define how AI-native interfaces behave in production systems and over complex datasets, blending chat with structured, guided interactions.
