What we look for

  • Professional coding experience

    Typically 2+ years shipping production software in at least one mainstream language.

  • Strong written English

    Most tasks require clear written rationales. We assess this from your application.

  • Analytical rigour

    AI training rewards engineers who can explain why something is right or wrong — not just fix it.

  • Reliable availability

    Even 10 focused hours a week is enough for many projects.

FAQ

Common questions

No. Credexus is 100% free for engineers. We are paid by the platforms and companies we place talent with — never by you, and never through deductions from your earnings.

AI labs need experienced engineers to write, review, debug and rank code produced by AI models, and to design hard problems that push models further. Your judgement becomes training and evaluation data that makes the models better.

Software engineers based in Latin America, Asia, Europe or Canada with professional coding experience and strong written English. Most projects look for 2+ years of experience; senior and specialist projects pay more.

Both. Many projects are flexible contracts from 10 hours a week, and some run full-time. You choose what fits around your current commitments.

We review your profile once, tell you which platforms fit your stack and level, help you prepare for their assessments, and introduce you where we can — so you skip the guesswork of applying blindly to a dozen platforms.

We aim to review every application within 3 business days. Onboarding timelines after that depend on each platform's assessment and project demand.

You are paid directly by the platform you work on, under its own terms — typically weekly or bi-weekly in USD through international payout providers. Credexus never handles your earnings.

Credexus is an independent recruiting agency. We list the platforms our candidates work on; this does not imply endorsement by those companies. All trademarks belong to their owners.
