C++ - Software Engineer, AI

Note: This role is open to contractors in accepted locations only. Confirm your country is on the list before applying — we’re unable to process applications from unlisted locations.

Help train large language models (LLMs) to write production-grade code across a wide range of programming languages:

• Compare and rank multiple code snippets, explaining which is best and why
• Repair and refactor AI-generated code for correctness, efficiency, and style
• Inject feedback (ratings, edits, test results) into the RLHF pipeline and keep it running smoothly

End result: the model learns to propose, critique, and improve code the way you do.

RLHF in one line: Generate code → expert engineers rank, edit, and justify → convert that feedback into reward signals → reinforcement learning tunes the model toward code you d actually ship.

• 3+ years of professional software engineering experience in C++ (constraint programming experience is a bonus, but not required)
• Strong code-review instincts — you can spot logic errors, performance traps, and security issues quickly
• Extreme attention to detail and excellent written communication skills. Much of this role involves explaining why one approach is better than another. This cannot be overstated.
• Comfortable reading documentation and language specs, and able to work well in an asynchronous, low-oversight environment

Identity verification: Applicants will be required to verify their identity and confirm they have valid documentation to work as an independent contractor in their country of residence.

• No prior RLHF or AI training experience

• Location: Fully remote — work from anywhere on the accepted locations list
• Compensation: $30–$70/hr based on location and seniority.
  
  Note:
  
  the majority of projects run at around $30/hr — higher rates apply to senior profiles and specific project types
• Hours: Minimum 15 hrs/week, up to 40+ hrs/week available — hours vary by project and are not guaranteed week to week
• Engagement: 1099 independent contractor
• Payment: Weekly via Pay Pal or Stripe

⚠️ Important:
Hours are project-dependent and can vary week to week. We recommend keeping other work options open alongside this engagement rather than relying on it as your sole source of income.
