Contract | Remote, worldwide | $100-$200/hour depending on experience and location | 10-20 hrs/week Check out this Loom video for more details: https://www.loom.com/share/b0d1b0bf24c44ae8b95dca84b9db60e5 We'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 is You 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 developer This 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 Code What 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 i
