## About the Role

2 or more years of professional full stack engineering experience.

Strong proficiency in Next.js for building modern frontend applications with server-side rendering and API routes.

Experience with Redis for caching, session management, and real-time data handling.

Solid experience designing and working with SQL databases such as PostgreSQL or MySQL, including schema design, queries, relationships, and optimization.

Experience with Tailwind CSS for building responsive, custom user interfaces.

Preferred qualifications:

Familiarity with authentication patterns, background jobs, and reporting or analytics features.

Comfort switching between unfamiliar domains and picking up new product requirements quickly.

## Description

We are hiring Full Stack Engineers to build complete, production-quality applications that become training examples for frontier AI models. Each application you build is a self-contained, end-to-end product across a different domain and use case. This is remote, asynchronous, project-based work with an expected commitment of 10 to 20 hours per week for the projects you accept.

What you will do:

Design and develop complete, production-quality applications from scratch across a range of business domains using Next.js, Redis, and SQL databases.

Build diverse application types including dashboards, management systems, workflow tools, and data-driven platforms that demonstrate different feature sets and architectural patterns.

Implement full functionality in each application including user authentication, data management, real-time features, reporting, and business logic.

Architect efficient data flows between the frontend, caching layer, and database so applications stay responsive under load.
