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.

Why We’re Hiring

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.

About the Role

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.

What You’ll Do

AI Product Development

  • Build end-to-end AI features from backend services through to frontend UI

  • Design and implement LLM agent systems including tool use, planning, and multi-step execution

  • Develop streaming APIs (SSE) that power real-time conversational interfaces

  • Own features from concept through production, iterating based on user feedback

Backend Systems & AI Infrastructure

  • Build and scale TypeScript and Python services for AI orchestration and document processing

  • Work with multiple LLM providers (Claude, GPT, etc.) and optimize for cost, latency, and quality

  • Develop asynchronous pipelines using AWS services (Lambda, SQS, S3, Textract)

  • Design APIs and data models that connect AI capabilities to the core platform

Frontend Experience

  • Build responsive, interactive UIs using React and TypeScript

  • Implement real-time streaming interfaces for conversational AI features

  • Collaborate with design to create polished, accessible experiences

  • Contribute to frontend architecture and state management patterns

Cross-Functional Collaboration

  • Partner with product and design to define AI feature roadmaps

  • Integrate with the core platform team on APIs, data models, and SDK surfaces

  • Contribute to architectural decisions around agent design, prompt engineering, and system reliability

  • Translate customer workflows into AI-powered solutions

About You
  • 3–6+ years of experience building full stack applications

  • Strong TypeScript/JavaScript proficiency with React experience

  • Backend experience with Node.js/Express, Python/Django, or similar

  • Genuine interest in AI/LLM technology and building AI-powered products

  • API design experience, including streaming and event-driven patterns

  • AWS or cloud infrastructure familiarity

  • Comfort shipping iteratively in a fast-paced, high-growth startup

  • Strong communication and collaboration skills

Bonus
  • Hands-on experience building with LLM APIs (Claude, GPT, etc.) — tool use, prompt engineering, or agent architectures

  • Document processing, OCR, or data extraction experience

  • Experience with streaming protocols (SSE, WebSockets) and real-time UIs

  • Familiarity with multi-model orchestration or AI pipeline design

  • High throughput and low latency optimization background

  • Financial services or regulated industry experience

  • High-growth B2B SaaS company background

What We Offer
  • Competitive compensation and equity

  • Health, dental, and vision coverage

  • Unlimited PTO

  • Downtown Toronto office location

  • Office snacks and lunches

  • A supportive, low-ego team that values ownership and growth

  • Company offsite to connect and recharge

If you’re excited about building AI product experiences that power critical workflows — and want to have a meaningful impact at a fast-growing startup — we’d love to meet you.
