About AI Training and Code Evaluation
AI training is the human side of building artificial intelligence. People review examples, evaluate model responses, and provide structured feedback so AI systems can become more accurate, useful, and reliable.
As a code evaluator, you will assess whether AI-generated programming content is correct, executable, maintainable, and aligned with instructions. Your feedback will help shape how AI systems handle Dart and Flutter development tasks.
Work on cutting-edge AI training and evaluation
Apply software engineering judgment to model-generated code
Help improve technical accuracy, safety, and instruction-following
The Dart QA Lead Role
OpenTrain AI is seeking an experienced technical reviewer to assess AI-generated Dart code and trainer QA work. You will evaluate correctness, type safety, asynchronous behavior, Flutter awareness, debugging accuracy, readability, maintainability, performance, test coverage, formatting, instruction-following, and rubric adherence.
You will also provide precise written feedback, answer technical questions, maintain Dart-specific quality materials, and support contributor onboarding and ongoing quality improvement.
Review AI-generated Dart and Flutter code for technical quality
Evaluate trainer and QA work against project guidelines
Lead quality improvement for Dart-focused training work
What You'll Do
This role combines hands-on code review with documentation, communication, and contributor support. You will help establish consistent standards and identify recurring quality issues across the training workflow.
Assess work for syntax, null safety, asynchronous behavior, logic, APIs, testing, and rubric compliance.
Provide detailed written feedback and answer questions about Dart, Flutter, packages, tests, and guideline interpretation.
Communicate guideline changes and Dart-specific standards to contributors and reviewers.
Create and maintain style guides, examples, trackers, FAQs, calibration tasks, honeypots, and onboarding materials.
Support onboarding and training calls for Dart contributors.
Flag insecure, misleading, non-executable, or non-production-ready Dart and Flutter recommendations.
Help address recurring QA gaps and contributor activation follow-ups.
Required Skills and Experience
You should have strong practical knowledge of Dart and Flutter, along with the ability to explain technical issues clearly in written English. Experience leading or supporting remote teams is strongly preferred, while AI training, LLM evaluation, code QA, or rubric-based code review experience is a strong plus.
Strong Dart and Flutter knowledge, including syntax, null safety, classes, mixins, extensions, generics, collections, futures, streams, isolates, packages, and error handling.
Ability to identify incorrect async handling, type errors, weak null-safety usage, flawed logic, hallucinated APIs, and incomplete explanations.
Familiarity with widgets, state management, pub.dev packages, unit testing, widget testing, integration testing, build tools, and mobile app architecture.
Familiarity with GitHub and CI/CD workflows.
Strong English communication skills for clear, precise technical feedback.
Experience leading or supporting remote teams of trainers, engineers, reviewers, or QA professionals is strongly preferred.
Experience with AI training, LLM evaluation, code QA, or rubric-based code review is a strong plus.
