Who this role is best for

Geared toward senior-level engineers with experience in AI-assisted development workflows and a strong grasp of JavaScript/TypeScript or Python, comfortable with evaluating AI-generated code for engineering judgment and clarity

Best fit for

  • Senior engineers with AI-assisted dev experience and strong judgment in code quality
    — “Senior, Staff or Principal-level engineer (or equivalent experience)”
  • Individuals with deep familiarity with modern AI tools and their real-world usage
    — “Deep familiarity with modern AI-assisted dev workflows”

Things to consider

  • This role requires strong written English to document evaluations and feedback
    — “Strong written and spoken English (B2 or above)”
  • Candidates must be available for ongoing projects with variable duration and start dates
    — “Duration: ongoing. Projects run from about two weeks to a few months each”

How to stand out

  • Highlight experience evaluating code quality and providing structured feedback
    — “Give clear, opinionated feedback in writing on what worked, what didn't, and what felt off or misleading”
  • Emphasize your ability to judge engineering judgment, not just syntax
    — “Syntax correctness is the easy part”
  • Showcase hands-on experience with AI coding tools like Codex or Claude Code
    — “Hands-on experience with at least one of OpenAI Codex, Claude Code or Cursor”
  • Demonstrate your capability to assess reasoning and explanations in code interactions
    — “Assess the quality of explanations and reasoning, not just the code”
  • Demonstrate your ability to evaluate code without reviewing every line
    — “Able to evaluate code without executing it or reviewing every line”

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
