Senior Software Engineer, (OpenAI Codex, Claude Code or Cursor)
Quick Summary
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer (OpenAI Codex,
We are seeking a highly experienced software engineer to evaluate the quality of interactions produced by advanced AI coding agents. Rather than developing production software, you will apply your engineering expertise to assess how tools such as OpenAI Codex, Claude Code, and Cursor reason, communicate, and guide developers through real-world technical challenges. You will examine the usefulness of explanations, the quality of technical judgment, and the overall developer experience. Your feedback will help establish clear standards for what excellent AI-assisted software engineering should look like. This opportunity is suited to senior-level engineers with strong technical instincts, a critical eye, and the ability to communicate nuanced assessments. The engagement is fully remote, flexible, and project-based.
In this role, you will assess AI-generated coding interactions from the perspective of an experienced software engineer, focusing on technical judgment, clarity, usefulness, and the quality of the overall developer experience.
-
Evaluate AI-generated coding interactions from beginning to end, including responses, explanations, and recommendations.
-
Assess whether outputs are useful, broadly correct, and consistent with the judgment and practices of a strong software engineer.
-
Review the quality of explanations and reasoning rather than focusing exclusively on code syntax or implementation details.
-
Distinguish between different levels of response quality using consistent evaluation criteria.
-
Provide clear, detailed, and constructive written feedback explaining what worked, what did not, and what felt inaccurate, misleading, or ineffective.
-
Evaluate whether AI agents guide developers effectively, build trust, and provide meaningful assistance rather than simply generating output.
-
Help define and refine quality standards for interactions with AI coding tools such as OpenAI Codex, Claude Code, and Cursor.
-
Record short video explanations to communicate evaluation findings and provide additional context.
Requirements
~1 min readThe ideal candidate is a senior software engineering professional with extensive experience, strong technical judgment, and a deep understanding of modern AI-assisted development workflows.

-
Senior, Staff, or Principal-level software engineer, or equivalent professional experience.
-
Strong background in TypeScript, JavaScript, or Python.
-
Hands-on experience using at least one of the following tools: OpenAI Codex, Claude Code, or Cursor.
-
Deep familiarity with modern AI-assisted software development workflows.
-
Ability to evaluate code and technical responses without necessarily executing the code or reviewing every line.
-
Strong written and spoken English proficiency (B2 level or above), as detailed written feedback and short recorded video explanations are required.
-
Confidence in providing direct, thoughtful, and opinionated feedback.
-
High standards for software engineering quality and a strong understanding of what makes technical guidance genuinely useful.
-
Ability to assess engineering judgment, communication quality, and developer experience beyond basic technical correctness.
-
Previous experience with prompt design, AI evaluation, or model assessment workflows.
-
Experience mentoring senior engineers or establishing engineering standards and best practices.
