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, Claude Code or Cursor) based in Netherlands. 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. This position is listed on behalf of a partner company, who manages all applications and next steps.

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. - 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 The ideal candidate is a senior software engineering professional with extensive experience, strong technical judgment, and a deep understanding of modern AI-assisted development workflows. You should be comfortable evaluating technical work critically, making subjective but well-reasoned assessments, and communicating your conclusions clearly. - 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. Nice to have: - Previous experience with prompt design, AI evaluation, or model assessment workflows. - 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. - Fully remote engagement, with worldwide opportunities subject to regional eligibility. - Flexible workload of approximately 10–20 hours per week. - Ongoing collaboration, with individual projects typically lasting from two weeks to several months. - Opportunities to participate in additional projects based on evaluation performance. - Flexible working hours. - Streamlined selection process consisting of one take-home evaluation exercise and a recorded video walkthrough, with no interview required. - Opportunity to contribute to the development and evaluation of cutting-edge AI coding tools. - Contract-based engagement, with projects offered on an ongoing basis. - Potential to start as soon as the evaluation exercise is successfully completed and a project position becomes available.
