About The RoleWhat if the code you write could directly shape how the next generation of AI understands and generates software? We're looking for Software Engineers in Seville to build, evaluate, and improve AI-generated code — helping train AI systems to think like real developers. You'll write solutions, review AI outputs, and provide the expert‑level feedback that makes AI coding assistants smarter, safer, and more reliable. This is hands‑on engineering work at the frontier of AI development — not theoretical, not bureaucratic, and not boring. This is a fully remote, adaptable contract role. If you can write clean code and explain your reasoning, we want to hear from you.Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 10–40 hours/weekWhat You'll DoWrite, debug, and optimize code across a range of languages, frameworks, and problem domainsReview and evaluate AI‑generated code for correctness, efficiency, readability, and best practicesIdentify bugs, logic errors, security issues, and performance bottlenecks in AI outputsProvide structured,
