Software Engineer, AI - Ruby

About the Software Engineer, AI - Ruby Role at G2i Inc.

G2i Inc. is seeking a talented Software Engineer, AI - Ruby to help train large-language models (LLMs) to write production-grade code across a wide range of programming languages. This fully remote, contract position focuses on enhancing AI's ability to propose, critique, and improve code through human feedback.

Key Responsibilities

• Compare and rank multiple code snippets, clearly explaining the rationale for preferring one over others.
• Repair and refactor AI-generated code to ensure correctness, efficiency, and adherence to style guidelines.
• Integrate feedback, including ratings, edits, and test results, into the Reinforcement Learning with Human Feedback (RLHF) pipeline to ensure its smooth operation.
• Contribute directly to improving AI models, enabling them to produce high-quality, shippable code.

RLHF in Action

The process involves generating code, where expert engineers like you rank, edit, and justify their choices. This valuable feedback is then converted into reward signals, which are used in reinforcement learning to fine-tune the model toward generating production-ready code.

What You'll Need

• 3+ years of professional software engineering experience, specifically with Ruby.
• Strong code-review instincts, enabling quick identification of logic errors, performance traps, and security vulnerabilities.
• Exceptional attention to detail and outstanding written communication skills, particularly for explaining complex code decisions.
• An enjoyment for reading documentation and language specifications, and a preference for asynchronous, low-oversight work environments.

What You Don't Need

• Prior experience with RLHF (Reinforcement Learning with Human Feedback) or AI training is not required.
• Deep machine learning knowledge is not a prerequisite. If you possess strong code review and critique abilities, G2i Inc. will provide the necessary training in AI specifics.

Tech Stack

Candidates should have a strong command of Ruby.
