Job Description

Timeline: Part-time to start, with potential to go full-time

Fallyx is hiring a full-stack developer to help build and scale our incident analysis platform for senior care homes. Our tool processes incident reports -- including falls, behaviours, and other events -- and automatically summarizes key information, identifies trends, and suggests ways to improve quality of care. Executive teams and staff use our product to drive better decision-making and reporting across their homes.

We're looking for someone who wants to be a core team member -- someone who's ready to take full ownership over the full stack and scale real software that care homes rely on. We'd advise against applying if you're looking for a simple 9-5 job. The product has over 30 homes using it and there are constant improvements that need to be made. Expect context-switching, feedback loops that span hours (not weeks), and an environment where execution matters more than polish.

You'll work across both the backend and frontend -- developing APIs, maintaining infrastructure, and improving user-facing dashboards and reports.

Next.js 15, React 19, TypeScript, Tailwind CSS, Jotai, Firebase, Recharts

Backend:

What You'll Do

Develop and maintain REST APIs in Express using domain-driven principles Work with Sequelize to manage PostgreSQL models and migrations Integrate tools like Firebase Auth, Firebase Storage, OpenAI (for PDF analysis), and Sentry Write tests with Jest and Testcontainers (backend) and Playwright (frontend) Build and maintain responsive UIs in React 19, using Tailwind and shadcnbased components Fetch and manage data with Axios, React Query, and Jotai Implement interactive dashboards and chart components with Recharts Collaborate through Git and maintain a Docker-based dev environment
