This co-op is ideal for students who have built meaningful projects, enjoy learning new technologies quickly, and want hands‑on experience with production‑grade systems.

Requirements

Currently pursuing a degree in Computer Science, Engineering, or a related field.
Coursework or project experience with JavaScript/TypeScript.
Hands‑on experience building React applications (class projects, personal projects, hackathons, etc.).
Familiarity with Node.js; experience with NestJS is a plus but not required.
Understanding of REST APIs, JSON, and asynchronous programming.
Experience using ReactQuery/TanStack Query or similar data‑fetching/state tools.
Comfort working with external APIs and handling varied data formats.
Curiosity about agentic development, LLM‑powered workflows, or tool‑calling patterns.
Interest in applying models for classification, tagging, or inference tasks.

Understanding of basic ML concepts (classification, embeddings, etc.).
Experience building dashboards or data‑rich UI components.

Responsibilities

Build responsive, component‑driven React front‑end features using modern tooling.
Develop and maintain backend endpoints using Node.js and NestJS.
Integrate with first- and third‑party APIs (Facebook, Instagram, TikTok, Snapchat, etc.) to fetch, normalize, and aggregate data.
Implement state management and data‑fetching patterns using ReactQuery/TanStack Query.
Use agentic development practices to design workflows that call models or tools autonomously.
Work with ML‑powered inference to classify data.
