SENIOR AI INTERACTION EVALUATOR (CODEX / CLAUDE CODE)
Contract | $50-200/hr | 10+ hrs/week | Project-based
Roles open on a rolling basis - apply to join the talent bench and we’ll reach out when one matches. Expect 40+ hrs once a project starts; timing depends on availability, but we move people in at the earliest genuine opportunity.
These roles are currently filled but we hire on a rolling basis as new projects open up. Apply now to join our talent bench — qualified candidates will be contacted directly when roles become available.

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 — not syntax correctness.
WHAT YOU’LL BE DOING
- Evaluate AI-generated coding interactions end-to-end
- Judge whether outputs are: - Useful - Correct (at a high level) - Aligned with how a strong engineer would think
- Assess the quality of explanations and reasoning, not just code
- Distinguish between different levels of response quality (e.g. what makes something a 2 vs 4)
- Provide clear, opinionated feedback on: - What worked - What didn’t - What felt “off” or misleading
- Help define what great looks like when interacting with tools like Cursor
WHAT WE MEAN BY “TASTE”
We’re specifically 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.
WHO YOU ARE
- Staff / Principal-level engineer (or equivalent experience)
- Strong background in one of the below: - TypeScript / JavaScript - Python
- Hands-on experience using: - OpenAI Codex - Claude Code - Cursor
- Deep familiarity with modern AI-assisted dev workflows
- Able to evaluate code without needing to fully execute or deeply review every line
- Comfortable giving direct, opinionated feedback
- High bar for what “good engineering” looks like
NICE TO HAVE
- Experience with tools like Cursor or similar AI-first IDEs
- Prior exposure to prompt design or evaluation workflows
- Experience mentoring senior engineers or defining engineering standards
