• Solid SQL skills, including complex queries, joins, and data validation
• Prior consulting or client-facing experience, with the ability to reason through open-ended problems independently

Nice to Have

• Experience working with large, messy, or unstructured datasets
• Familiarity with backend systems, REST APIs, or data pipelines
• Comfort evaluating and critiquing AI-generated code or analytical outputs
• Strong written communication and meticulous attention to detail

Why Join Us

• Work on cutting-edge AI projects alongside leading research labs
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, task-based engineering work
• Apply your deepest technical skills to problems that genuinely matter at scale
• Potential for ongoing work and contract extension as new projects launch
