Our partner is looking for a Senior Software Engineer (OpenAI Codex, Claude Code or Cursor) based in Spain. 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. Accountabilities 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. - 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 The adecuado 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. - Deep familiarity with modern AI-assisted software development workflows. - Strong written and spoken English proficiency (B2 level or above), as detailed written feedback and short recorded video explanations are required. - 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. Experience mentoring senior engineers or establishing engineering standards and best practices. Benefits - Competitive hourly compensation ranging from $100 to $200, depending on experience and location.
