An enterprise client is currently seeking experienced software engineers to contribute to improving advanced AI systems through human feedback. This work supports leading AI organizations in training large language models to better understand software development practices, debugging, and code quality.

  • Review system logs and execution paths to improve reliability and code quality
  • Refactor code and optimize system behavior toward ideal outcomes
  • Test systems for vulnerabilities, including data exposure and edge-case failures

  • Proven ability to build and maintain production-grade systems
  • Experience working in live (non-mocked) environments with multi-step interactions
  • Strong analytical skills and attention to detail

Nice to Haves:
  • Experience with multi-stage system workflows and coordination tasks
  • Familiarity with integrating tools such as APIs, databases, or external platforms
  • Understanding of system vulnerabilities (e.g., privacy leaks, prompt injection, access escalation)
  • Experience working with AI systems or agent-based workflows
  • Comfort working with persistent state tracking or similar frameworks

Additional Information
  • Fully remote and flexible work schedule
  • Project-based engagement with no guaranteed hours
  • Work on tasks based on availability and project assignment
