This opportunity is ideal for engineers who enjoy analyzing systems, improving code quality, and working on complex technical challenges. You will contribute to AI training projects by evaluating outputs, refining logic, and identifying potential vulnerabilities.

• Strong proficiency in at least two programming languages (e.g., Python, JavaScript, Go, Java)
• Experience working with SQL databases
• 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

• Fully remote and flexible work schedule
• Project-based engagement with no guaranteed hours
• Work on tasks based on availability and project assignment
• Payment is based on completed tasks only
• Must accept project invitations before beginning work
