Ai Engineer • Mid-Level

Who you are

You have 3+ years of professional software engineering experience in Java — your strong code-review instincts allow you to quickly spot logic errors, performance traps, and security issues. You possess extreme attention to detail and excellent written communication skills, as much of this role involves explaining why one approach is better than another. You enjoy reading documentation and language specifications, thriving in an asynchronous, low-oversight environment. While prior experience in reinforcement learning with human feedback (RLHF) is not required, your ability to review and critique code clearly will be essential in this role.

Desirable

Experience with constraint programming is a bonus, but not required. You are eager to learn and adapt to new technologies and methodologies, and you are comfortable working in a remote setting.

What you'll do

In this role, you will help train large-language models (LLMs) to write production-grade code across a wide range of programming languages. You will compare and rank multiple code snippets, explaining which is best and why. Your responsibilities will include repairing and refactoring AI-generated code for correctness, efficiency, and style. You will inject feedback, such as ratings, edits, and test results, into the RLHF pipeline, ensuring it runs smoothly. The end result of your work will be that the model learns to propose, critique, and improve code in a manner similar to expert engineers.

You will also be involved in generating code, where expert engineers rank, edit, and justify their choices, converting that feedback into reward signals that reinforce learning. Your contributions will directly impact the effectiveness of the AI models and their ability to generate high-quality code.

What we offer

This position is fully remote, allowing you to work from anywhere. Compensation ranges from $30/hr to $70/hr, depending on your location and seniority. You will have the flexibility to work a minimum of 15 hours per week, with the option to increase up to 40 hours per week. This is a 1099 contract role, providing straightforward impact without unnecessary fluff. If this sounds like a fit, we encourage you to apply.
