AI Trainer – LLM & Generative AI Specialist

About the role

We are looking for a detail‑oriented AI Trainer to help shape the next generation of large language models and generative AI systems. You will work remotely with a global team, designing training workflows, creating high‑quality datasets, and analysing model behaviour.

Key responsibilities

• Architect and manage end‑to‑end training pipelines, including supervised fine‑tuning (SFT) and Reinforcement Learning from Human Feedback (RLHF).
• Develop complex prompt templates and testing scenarios across coding, creative writing, reasoning, and multilingual tasks.
• Define and maintain rubrics for model output quality and produce “golden datasets” as standards.
• Analyse model failures, identify bias or hallucination root causes, and document findings.
• Guide junior trainers and annotators, ensuring consistency and high standards.
• Collaborate with ML engineers and product managers to translate research goals into actionable annotation tasks.
• Identify workflow bottlenecks and propose improvements to internal tools.
• Design strategies for generating synthetic data to strengthen model robustness.

Required profile

• Minimum 2 years of experience in a relevant technical field (e.g., software engineering, computer science).
• Strong analytical mindset with ability to dissect complex problems and articulate abstract concepts.
• Comfortable reading technical papers and staying updated on AI safety research.
• Proven ability to manage multiple projects, prioritize tasks, and meet tight deadlines.
• Flexibility to shift between technical (e.g., code ranking) and creative (e.g., fiction writing) tasks.

Required skills

• Python
• JSON
• APIs
