About AI Training Work

AI training is the human side of building artificial intelligence. Experts review examples, evaluate model outputs, and provide precise feedback so AI systems can become more accurate, useful, secure, and reliable. In this project, your code-review expertise will help evaluate the quality of AI-generated programming responses.

• Contribute directly to the development of next-generation AI models.
• Use specialized technical knowledge in a growing, remote-first industry.
• Combine independent project work with structured quality standards.

The Role

OpenTrain AI is seeking a senior Angular engineer to audit annotator reviews of AI-generated JavaScript and Angular code. You will install dependencies, build each project with Angular CLI, run it in a sandbox, and verify that it fulfills the prompt, renders correctly, and follows modern engineering practices.

You will also identify and correct mis-ratings, provide concise feedback, and ensure every review meets the project quality rubric while protecting the data used to train AI systems. The role is listed at an intermediate experience level but requires 7+ years of professional Angular or JavaScript development, QA, or dedicated code-review experience.

• Pay: $23 USD per hour.
• Time requirement: 20+ hours per week.
• Engagement: Part-time contractor.
• Eligible locations: India, the Philippines, and Vietnam.
• Working language: English.

What You’ll Do

You will validate AI-generated Angular projects from installation through execution, assessing both whether the implementation works and whether it follows the prompt and applicable quality standards.

• Install dependencies and build projects using Angular CLI.
• Run projects in a sandbox and confirm functional correctness.
• Check whether responses fulfill the original prompt.
• Evaluate rendering behavior, code quality, and engineering best practices.
• Review security practices, including XSS and CSRF prevention.
• Assess performance practices such as AoT, lazy loading, and RxJS efficiency.
• Check accessibility and WCAG-compliant user interface components.
• Correct inaccurate annotator ratings and provide concise, constructive feedback.
• Apply rubric-based scoring, checklist reviews, and structured QA workflows.
• Safeguard the data used to train next-generation AI models.

Required Qualifications

This role requires advanced Angular and JavaScript expertise, strong testing and debugging ability, and the judgment to validate containerized builds against a detailed review rubric.

• 7+ years of professional Angular or JavaScript development, QA, or dedicated code review experience.
• Expertise with Angular 15+, RxJS, standalone components, Ivy, Angular CLI, SSR or Universal, and state-management patterns such as NgRx and Signal Store.
• Strong ES2023 knowledge, including ESM and CJS module systems and TypeScript typings used in modern Angular code.
• Advanced experience with Jest or Karma, Cypress or Playwright, Angular Testing Library, Istanbul or nyc, and performance profiling.
• Ability to detect and mitigate XSS, CSRF, injection, and supply-chain vulnerabilities, including familiarity with Snyk or npm-audit.
• Skill with bundle optimization, code splitting, Web Vitals, CLS, and accessible user interfaces.
• Proficiency with Docker, multi-stage images, CI/CD using GitHub Actions or GitLab, and pull request or merge request workflows.
• Comfort spinning up containerized builds to verify functional correctness and prompt compliance.
• Familiarity with Jira, Asana, annotation tools, rubric-based scoring, and checklist reviews.
• Excellent written English at B2+ CEFR or higher.

Communication and Collaboration

The strongest contributors can explain technical issues clearly and concisely. You should be comfortable delivering constructive feedback, maintaining consistent review standards, and mentoring peers when needed.

• Communicate findings in concise, actionable written feedback.
• Apply quality rubrics consistently across varied code submissions.
• Support peer learning through clear technical explanations and mentoring.
• Nice to have: exposure to LLM evaluation, RLHF pipelines, or AI and machine-learning data-labeling projects.
