Full Stack Engineer

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.

As Feathery grows, both the complexity of our backend systems and the sophistication of our frontend product experience are increasing.

• Design and build end-to-end features across frontend and backend systems

• Develop APIs and services that power core product functionality

• Build intuitive, responsive, and high-performance user interfaces

• Implement user interfaces using modern frameworks (e.g., React)

• Optimize frontend performance, responsiveness, and usability

• Collaborate with design to deliver polished, accessible user experiences

• Contribute to frontend architecture and component systems

• Partner with product and design to define and build new features

• Work with other engineers to integrate APIs and data models effectively

• Strong proficiency in JavaScript/TypeScript and modern frontend frameworks (e.g., React)

• Experience with backend frameworks such as Node.js, Django, or similar

• Experience designing APIs and working with distributed systems or asynchronous processing

• Familiarity with AWS and cloud infrastructure

• Strong understanding of performance, scalability, and reliability

• Experience shipping features end-to-end in a collaborative environment

• Comfortable working in a fast-paced, high-growth startup environment

• Experience building workflow tools, internal platforms, or data-heavy applications

• Familiarity with document processing, OCR, or AI/ML integrations

• Experience with drag-and-drop interfaces or complex frontend state management

• Background in financial services or other regulated industries

• Experience at a high-growth B2B SaaS company

• Competitive compensation and equity

• Health, dental, and vision coverage
