Remote Senior EMEA Artificial Intelligence Senior Software Engineer Remote Assistant Hugging Face PyTorch Python

Requirements

• You’ve personally post-trained open-weight LLMs for a user-facing product and shipped them to production • You’ve worked where AI was core to the product or business, not an experimental side feature • Fine-tuning is core to your experience • Strong Python, PyTorch and Hugging Face, with hands-on GPU training and debugging • You build data and evals yourself and make decisions from evidence • You can take work beyond notebooks into production • You use AI tools daily in your own engineering work • You are fully comfortable working with uncensored models and explicit NSFW content, including harmful material when developing and evaluating moderation system • Experience with conversational AI, roleplay products, or highly personalized consumer AI • Multilingual LLMs • Moderation, safety, or adversarial testing • Multimodal models • Open-source LLM / post-training contributions

Responsibilities

• Most LLM roles stop at experimentation. • Here, the models you improve power experiences for 50M+ users. • Most of our traffic runs on self-hosted, fine-tuned open-weight models. On our internal roleplay evals, our smaller fine-tuned models can outperform much larger off-the-shelf models. Your job is to make them better. • You’ll join a small AI team led by Marco, our LLM Tech Lead, working closely with our CTO, Product, Web and DevOps teams. You’ll work across data, post-training, evals, and model behavior, taking ideas from failure analysis to production. • The problems are real: personalization, character consistency, long conversations, better evals, multilingual behavior, and faster training cycles. • If you want to shape model behavior at consumer scale, this is the role. • Fine-tune open-weight LLMs using SFT, LoRA/QLoRA and post-training methods such as DPO and GRPO • Diagnose model failures and turn them into experiments. Decide whether the answer is better data, post-training, prompting or classifiers • Build training data and evals that directly shape what gets trained next • Improve model behavior across personalization, consistency, tone, multilingual and group interactions • Ship to production and use real user behavior to guide the next iteration • Speed up the training loop so experiments are faster, easier to compare, and more reproducible
