Repo-based Code Annotator

Rex focuses on cognition-heavy work: reasoning evaluation, prompt design, domain-specific content generation, and model benchmarking. Instead of high-volume microtask queues, it prioritizes fewer, deeper tasks and pays accordingly, with a stated target of $25-45/hr for expert-level output.

It's Rex's reputation system: a running score of your reliability, consistency, and task quality. A stronger profile unlocks higher-paying tracks and priority access to premium projects like Project EVA (with 2077AI), so every task you complete affects what you get offered next.

RLHF and instruction-tuning dataset creation, LLM prompt and response evaluation, named entity recognition, computer vision annotation, content safety labeling, speech-to-text transcription, and red-teaming and safety evaluations. Your specific assignment depends on your skills and profile tier.

Practical, hands-on data work: recording short videos, categorizing images, rating text responses, or analyzing data. Tasks are designed to be short and distinct, typically 5 to 60 minutes each.

No set hours, no check-ins, no meetings. You log in when you want, pick up an available task, complete it, and submit; nobody is waiting on you in real time. That's different from remote employment, where you're expected online during business hours. The tradeoff: you're competing with others for available tasks, so an empty queue means there's simply nothing to do until more work is released.

Check the Job Facts panel above for this specific listing. Where no fact is confirmed yet: most of these roles skip a live interview and gate access through an automated assessment or qualification task instead, though some do add an interview step, so don't assume either way until you check the application flow.

Tasks here are scoped to Software Engineering, not generic labeling. As a Repo-based Code Annotator, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Software Engineering) rather than following a one-size-fits-all rubric. If you don't have hands-on Software Engineering background, this is likely not the right listing to start with.

You'll be taken to Rex's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.
