## About the Role

Software Engineering, Artificial Intelligence (AI), Software Engineering, Artificial Intelligence (AI) Agents, Artificial Intelligence (AI), Python Programming/Scripting Language, JavaScript, Writing Skills, English Language, Workflow Analysis, * 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

## Description

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.
