Full Stack Engineer - AI Product

About Feathery

Feathery automates data intake workflows for insurance and wealth management firms. Industry leaders rely on Feathery to power mission-critical workflows like underwriting, client onboarding, and automated account openings.

With rapid revenue growth and expanding enterprise demand, we’re scaling our engineering team to support increasingly complex, data-intensive workflows across our platform.

Feathery is building an AI-native product experience — from a conversational workflow builder that creates complex forms and logic on behalf of users, to intelligent document extraction and multi-LLM orchestration.

As our AI capabilities become central to the product, we're hiring a Full Stack Engineer to join the AI team and build these features end-to-end — from designing LLM-powered services and streaming APIs to crafting the interactive UI that brings them to life.

This is a high-ownership role on the AI team which blends:

• Working across the full stack to ship AI-powered product features

• Building systems that orchestrate LLM agents, process documents, and generate workflows

• Owning the frontend experiences that make them intuitive

• Working across Type Script services, Python APIs, React interfaces, and cloud infrastructure

You’ll zoom out to understand system architecture and zoom in to deliver polished, end-to-end product experiences.
