Dart Team Lead

In this hourly, remote contractor role, you will work as a Dart Quality Assurance Lead (QAL) to oversee quality, consistency, and trainer performance across Dart AI training projects. You will review AI-generated Dart code and trainer/QA work, evaluate output quality against project guidelines, provide precise written feedback, and ensure contributors follow expected standards.

You will assess work for code correctness, type safety, async behavior, Flutter awareness, debugging accuracy, readability, maintainability, performance, test coverage, formatting, instruction-following, and rubric adherence.

This role is with SME Careers, a fast-growing AI Data Services company and subsidiary of SuperAnnotate, delivering training data for many of the world’s largest AI companies and foundation-model labs. Your Dart quality leadership will help ensure Dart training data is accurate, executable, maintainable, clearly explained, and aligned with client expectations.

Selection process involves an AI interview, a domain-specific task, and an interview with a recruiter.

Important: There is no immediate project for this role; however, if qualified, you will be among the first experts we reach out to when relevant opportunities arise. This will also provide you with access to future projects available through our expert network.
