AI Software Engineer (Java)
Role Overview
This mid-level AI Software Engineer role involves training large-language models (LLMs) to produce high-quality code by comparing, ranking, and refining code snippets, and providing feedback to improve AI-generated code for correctness and efficiency. The engineer works in an asynchronous, low-oversight environment, focusing on code evaluation and training without requiring prior AI experience, directly impacting the model's ability to generate production-grade code.
Perks & Benefits
The job offers fully remote work from anywhere with flexible hours ranging from 15 to 40 hours per week, allowing for a good work-life balance. Compensation is competitive, ranging from $30 to $70 per hour based on location and seniority, and the role is a 1099 contract, providing straightforward impact in a low-fluff, asynchronous team culture that values independence and clear communication.
Full Job Description
Software Engineer, AI — Code Evaluation & Training (Remote)
List of accepted countries and locations
Help train large-language models (LLMs) to write production-grade code across a wide range of programming languages:
Compare & rank multiple code snippets, explaining which is best and why.
Repair & refactor AI-generated code for correctness, efficiency, and style.
Inject feedback (ratings, edits, test results) into the RLHF pipeline and keep it running smoothly.
End result: the model learns to propose, critique, and improve code the way you do.
RLHF in one line
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.
What You’ll Need
3+ years of professional software engineering experience in Java
(Constraint programming experience is a bonus, but not required)Strong code-review instincts—you can spot logic errors, performance traps, and security issues quickly.
Extreme attention to detail and excellent written communication skills.
Much of this role involves explaining why one approach is better than another. This cannot be overstated.You enjoy reading documentation and language specs and thrive in an asynchronous, low-oversight environment.
What You Don’t Need
No prior RLHF (Reinforcement Learning with Human Feedback) or AI training experience.
No deep machine learning knowledge. If you can review and critique code clearly, we’ll teach you the rest.
Tech Stack
We are looking for engineers with a strong command of Java.
