About the role
About The Role What if your years of software engineering experience could directly shape how AI writes code for millions of developers? We're looking for Software Engineers in Berlin to evaluate, rank, and refine AI-generated code — helping the next generation of coding assistants produce solutions that are correct, efficient, idiomatic, and production-ready. Your deep understanding of software architecture, design patterns, and real-world engineering trade-offs is exactly what AI models need to get better. This isn't about writing boilerplate — it's about applying expert judgment to push the boundaries of what AI can do with code. This is a fully remote, flexible contract role built for experienced developers who want meaningful, high-impact work on their own schedule. Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 10–40 hours/week What You'll Do Review and rank AI-generated code solutions across multiple programming languages and problem domainsEvaluate code for correctness, efficiency, readability, maintainability, and adherence to best practicesIdentify bugs, anti-patterns, security issues, and performance bottlenecks in AI-generated outputsWrite detailed, structured feedback explaining why one solution is better than anotherRefine and improve AI-generated code to meet production-level engineering standardsProvide preference rankings that help AI models learn what "good code" actually looks likeWork independently and asynchronously — fully on your own schedule Who You Are Software engineer with 3+ years of professional development experienceProficient in one or more major programming languages (e.g., Python, JavaScript/TypeScript, Java, C++, Go, Rust)Strong grasp of data structures, algorithms, and computational complexityDeep understanding of software design principles, clean code practices, and engineering trade-offsExperienced with code review — you know how to assess quality and articulate why something works or doesn'tClear, concise written communicator who can explain technical decisions effectively in EnglishSelf-motivated and reliable when working independently without supervision Nice to Have Experience across multiple languages, frameworks, or tech stacksBackground in systems design, distributed systems, or backend architectureFamiliarity with AI/ML concepts or experience using AI coding tools (Copilot, ChatGPT, etc.)Prior experience with code evaluation, technical mentoring, or open-source contributionKnowledge of security best practices and performance optimizationExperience in competitive programming or technical interviewing Why Join Us Work on cutting-edge AI projects alongside leading research labsDirectly influence how AI coding assistants learn to write better softwareFully remote and flexible — work when and where it suits youFreelance autonomy with the structure of meaningful, task-based workLeverage your hard-earned engineering expertise in a new, high-impact wayPotential for ongoing work and contract extension as new projects launchJoin a global community of top-tier engineers shaping the future of AI-assisted development
