Job description

About the role:

You will focus on training and fine-tuning large language models (LLMs) to support our product that generates HTML from prompts, inspired by email-like instructions. Our stack leverages diffusion models and pre-trained LLMs.

This is a hands-on role where your work will directly influence the product and shape the roadmap after launch.


What you’ll do:

  • Train, fine-tune, and evaluate LLMs for real-world applications.

  • Collaborate closely with the team to integrate models into our HTML-generation product.

  • Optimize model performance and training pipelines.

  • Contribute to the roadmap for future LLM enhancements post-MVP.


What we’re looking for:

  • Strong experience in training and fine-tuning LLMs (transformer-based models, diffusion models a plus).

  • Solid Python and ML framework skills (PyTorch, TensorFlow, Hugging Face, etc.).

  • Experience with prompt engineering and real-world LLM deployments.

  • Ability to work independently in a small, fast-moving team.

  • Enthusiasm for cutting-edge AI applied to practical products.
