Applied Machine Learning Engineer

Engineering5+ yearsRemote

Run BiOS gives enterprises one path from approved data to a trained, evaluated and deployed model. As an Applied Machine Learning Engineer, you own that path from dataset design and method selection through evaluation, deployment and continuous improvement.

What you'll do

  • 01Own fine-tuning engagements end to end: dataset inspection, method selection, run configuration, evaluation and handoff.
  • 02Build internal tooling for dataset validation, training orchestration and model evaluation across a catalog of 250k+ open models.
  • 03Debug the weird ones: loss spikes, adapter pathologies, tokenization edge cases, VRAM ceilings.
  • 04Feed recurring customer patterns back to product and research as concrete, prioritized proposals.
  • 05Help customers serve their fine-tuned weights through our inference stack.

What you bring

  • At least 5 years applying machine learning in production environments.
  • Real experience fine-tuning LLMs or vision-language models: configuring runs, reading curves, not only calling APIs.
  • Strong Python and PyTorch, and comfortable reasoning about GPU memory when things get tight.
  • Data instincts: you look at the dataset before you touch the model.
  • Clear communication: you can explain a failed run to a customer without hand-waving.

Nice to have

  • Breadth across model families: DeepSeek, Qwen, Kimi, GLM, Gemma and friends.
  • Depth in the Hugging Face ecosystem: transformers, PEFT, TRL, datasets.
  • Multi-GPU training frameworks and checkpoint management.
  • Serving experience: vLLM or similar inference stacks.
