Full Stack Engineer

$40 - $150 per hour
Temporary

DataAnnotation

Pay: up to $40 – $150+ /hour (depends on task difficulty and specialization)

Location: Remote · Type: Independent contractor · Hours: Flexible hours · Payouts: Weekly

Overview

Models can scaffold a whole app in one shot: front end, API, and database, all of it looking right. Then the state goes stale, the endpoint leaks data, and the migration bricks production. Someone has to trace a feature across every layer and find where it actually breaks, and that someone is you.

As a Full Stack Engineer you'll run frontier models on real end-to-end tasks, analyze what they build across the stack, and write the judgments that teach the next generation to ship features that hold together.

What you’ll actually do

  • Build with frontier models on real end-to-end tasks: wire a UI to an API, model the data, and see how far the model gets.
  • Trace the feature across layers to find where it breaks: stale state, leaky endpoints, and migrations that don't survive contact with real data.
  • Write the working version when the model falls short, sound from the component down to the schema.

Roles this fits

Common backgrounds: Full-Stack Engineer, Web Developer, Product Engineer.

What we look for

  • Professional or serious open-source experience shipping full-stack applications.
  • Comfort across the stack; most tasks span a JavaScript front end, an API layer, and a database.
  • Clear written English: your explanations are the training signal.
  • No degree required. We care about what you can do, not where you learned it.

Compensation

Up to $40 – $150+/hr depending on task difficulty and specialization. Many contributors add $10k–$100k+ a year; some make it their full-time income.

About DataAnnotation

DataAnnotation is where 100k+ experts train the world’s leading AI models. $150M+ paid to contributors to date, and the average contributor stays 5+ years. Flexible, remote, and always project-available.

How it works

Apply, pass the qualification assessment, then pick up paid projects whenever you want and get paid weekly.
