What this role actually is
We're looking for highly experienced software engineers (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.
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
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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
