Senior Software Engineer, AI Training - US

G2i Inc.

4d•$100 - $200•Remote

About The Position

We are seeking highly experienced software engineers (SR+) to evaluate the quality of interactions with modern coding agents such as OpenAI Codex and Claude Code. This is not a traditional engineering role where you will be writing production code. Instead, you will be evaluating a more complex aspect: whether the AI model thinks like a great engineer. You will assess how AI coding agents behave in real-world scenarios, focusing on the sensibility of the response, the usefulness of the preamble and reasoning, whether the output reflects strong engineering judgment, and if the interaction feels right to an experienced developer. This role emphasizes engineering taste, going beyond mere syntax correctness.

Requirements

Senior, Staff or Principal-level engineer (or equivalent experience).
Strong background in TypeScript/JavaScript or Python.
Hands-on experience with at least one of OpenAI Codex, Claude Code or Cursor.
Deep familiarity with modern AI-assisted dev workflows.
Able to evaluate code without executing it or reviewing every line.
Strong written and spoken English (B2 or above).
Comfortable giving direct, opinionated feedback.
High bar for what good engineering looks like.

Nice To Haves

Prior exposure to prompt design or evaluation workflows.
Experience mentoring senior engineers or defining engineering standards.

Responsibilities

Evaluate AI-generated coding interactions end to end.
Judge whether outputs are useful, correct at a high level, and aligned with how a strong engineer would think.
Assess the quality of explanations and reasoning, not just the code.
Distinguish between levels of response quality.
Give clear, opinionated feedback in writing on what worked, what didn't, and what felt off or misleading.
Help define what great looks like when working with tools like Cursor, Codex and Claude Code.
