Senior Software Engineer - Applied AI

Feathery is the AI operating system for financial institutions. With hundreds of clients and over $30 million raised, Feathery is the fast-growing leader in financial agentic automation. Industry leaders like Tokio Marine, Sequoia Financial, and Cerity Partners run their client-facing workflows on Feathery, from onboarding and risk assessment to reconciling systems and generating proposals and reports.

At the center of it all is Robin, our AI operations assistant. Robin scans client documents, configures and deploys workflows, assists users in their day-to-day work, takes notes during meetings, and supports a growing range of operational tasks across the client lifecycle.

We're building a future where financial operations shift from paperwork, manual data entry, and disconnected systems to intelligent, automated workflows that let firms spend their time on clients instead of process. We're proud to be backed by world-class investors who share that vision, including Portage Ventures, Allstate Ventures, and Index Ventures, among others.

We're driven by a shared commitment to excellence and velocity. Our values — Own the Problem, Grit Beats Gloss, Say It Straight — shape how we work and grow as a team.

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 TypeScript 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.
