Your Role
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.
Key Responsibilities
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
Your Qualifications
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
Bonus points
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
