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 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 like

Nice to have

  • Prior exposure to prompt design or evaluation workflows

  • Experience mentoring senior engineers or defining engineering standards

Engagement 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
