## Description

Contract | Remote, worldwide | $100-$200/hour depending on experience and location | 10-20 hrs/weekCheck out this Loom video for more details: https://www.loom.com/share/b0d1b0bf24c44ae8b95dca84b9db60e5We're looking for highly experienced software engineer (SR+) to help evaluate the quality of interactions with modern coding agents such as OpenAI Codex and Claude Code.This is not a traditional engineering role. You won't be writing production code. You'll be evaluating something harder: whether the model thinks like a great engineer.What this role actually isYou will assess how AI coding agents behave in real-world scenarios, focusing on:* Whether the response makes sense* Whether the preamble and reasoning are useful* Whether the output reflects strong engineering judgment* Whether the interaction feels right to an experienced developerThis role is about engineering taste. Syntax correctness is the easy part.What you'll be doing* 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 (what makes something a 2 vs a 4)* 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 CodeWhat we mean by "taste"We're looking for engineers who can answer questions like:* Does this feel like something a strong engineer would actually say?* Is this explanation helpful, or just technically correct?* Is the model guiding the user well, or just dumping output?* Would this interaction build or erode trust?You should be comfortable making subjective but rigorous judgments, and explaining them clearly.Who you are* 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). You'll be writing detailed feedback and recording short video explanations, so this is a hard requirement* Comfortable giving direct, opinionated feedback* High bar for what good engineering looks likeNice to have* Prior exposure to prompt design or evaluation workflows* Experience mentoring senior engineers or defining engineering standardsEngagement details* Rate: $100-$200/hour depending on experience and location* Hours: 10-20 hours/week, flexible* Duration: ongoing. Projects run from about two weeks to a few months each, and we offer new ones to evaluators who do well* Start: as soon as you clear the take-home and a project has an open seat* Process: one take-home evaluation exercise with a recorded Loom walkthrough. No interview
