Tech Lead, LLM & Generative AI (Full Remote - Europe)

8+ years of engineering experience, with a significant portion dedicated to shipping ML/LLM features to millions of active users. Proficient in Python/PyTorch and comfortable with the modern LLM stack (vLLM, HuggingFace, fine-tuning pipelines, eval frameworks). Understand the 'Uncensored' challenge and technical rigor for moderation. Intuition for LLM alignment: prompt conditioning, temperature, and sampling. Doer Mindset: Value velocity and shippable production solutions. Owner Mindset: Obsess over metrics, regressions, and user experience.

Act as a Player/Coach: Architect system and mentor team, hands-on in codebase (Python/PyTorch). Own the core chat loop: Optimize context windows, memory/RAG retrieval, and inference latency. Drive strategy for SFT and RLHF/DPO. Manage the 'Data Engine': oversee dataset sourcing, labeling, and cleaning. Design and train custom classifiers for moderation in explicit environments.
