List of accepted countries and locations

\n

Help train large-language models (LLMs) to write production-grade code across a wide range of programming languages:

\n

    \n
  • Compare & rank multiple code snippets, explaining which is best and why.
  • \n
  • Repair & refactor AI-generated code for correctness, efficiency, and style.
  • \n
  • Inject feedback (ratings, edits, test results) into the RLHF pipeline and keep it running smoothly.
  • \n
  • End result: the model learns to propose, critique, and improve code the way you do.
  • \n

\n

RLHF in one line

\n

Generate code ➜ expert engineers rank, edit, and justify ➜ convert that feedback into reward signals ➜ reinforcement learning tunes the model toward code you'd actually ship.

\n

What You'll Need

\n

    \n
  • 4+ years of professional software engineering experience in Java
  • \n
  • (Constraint programming experience is a bonus, but not required)
  • \n
  • Strong code-review instincts—you can spot logic errors, performance traps, and security issues quickly.
  • \n
  • Extreme attention to detail and excellent written communication skills.
  • \n
  • Much of this role involves explaining why one approach is better than another. This cannot be overstated.
  • \n
  • You enjoy reading documentation and language specs and thrive in an asynchronous, low-oversight environment.
  • \n

\n

What You Don't Need

\n

    \n
  • No prior RLHF (Reinforcement Learning with Human Feedback) or AI training experience.
  • \n
  • No deep machine learning knowledge. If you can review and critique code clearly, we'll teach you the rest.
  • \n

\n

We are looking for engineers with a strong command of Java.

\n

Logistics

\n

    \n
  • Location: Fully remote — work from anywhere
  • \n
  • Compensation: From $30/hr to $70/hr, depending on location and seniority
  • \n
  • Hours: Minimum 15 hrs/week, up to 40 hrs/week available
  • \n
  • Engagement: 1099 contract
  • \n
