Software Engineer, Frontend

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.
What you'll be doing

• Build the interaction layer for an AI-native product

Design and implement user interfaces that turn complex data, insights, recommendations into clear, actionable workflows.

• Translate complexity into intuitive experiences

Make complex data systems feel simple, fast, and navigable through strong interaction design and information architecture.

• Define AI-native UX patterns

Design interfaces that are suggestive, responsive, and trustworthy, guiding users toward decisions rather than leaving them with open-ended outputs.

• Own frontend systems and architecture

Build scalable frontend components and patterns that enable fast, consistent product development.

• Work across the stack

Partner closely with backend systems, on APIs, data models, and real-time infrastructure to deliver seamless product experiences.
Who you are

• A strong frontend engineer with product instincts

You build high-quality user experiences and care deeply about usability, interaction design, and performance.

• Comfortable across the stack

You’re strong in TypeScript, React (or similar), and modern frontend architecture, and comfortable working with APIs and backend systems.

• Experienced with complex interfaces

You’ve built analytics-heavy or workflow-driven products and know how to make them feel intuitive and fast.

• Interested in AI-native products

You have experience with or a strong curiosity about agent-driven systems and how they shape user interaction.

• A builder who thrives in ambiguity

You’re comfortable turning loosely defined problems into intuitive and reliable product experiences.
