Machine Learning Engineer

Palo Alto, CA

Nace.AI is a hive for people who see a tough problem and itch to solve it with AI. We mix curiosity, rigor, and play to turn raw research into tools that feel like magic.

Role Overview:

As a Machine Learning Engineer, you will play a central role in translating cutting-edge machine learning research into scalable, production-ready solutions. You will collaborate closely with cross-functional teams to identify opportunities where ML can drive product value, architect robust model-centric systems, and ensure their seamless integration into real-world applications. The role requires a strong balance between theoretical understanding and engineering execution, with a focus on building reliable, maintainable, and high-impact AI-driven features that align with Nace.AI’s strategic objectives.

Key Responsibilities:

  • Design, build, and maintain end-to-end ML systems, including synthetic data pipelines, model training, debugging, and performance evaluation.

  • Fine-tune large language models (LLMs) and implement meta-learning methods to enhance model generalization and efficiency.

  • Improve existing Nace.AI models by incorporating advancements from recent ML research.

Qualifications:

  • Hands-on experience training and fine-tuning large language models (LLMs) and vision-language models (VLMs), including practical work with pre-training, instruction tuning, and alignment techniques (GRPO,RLHF/DPO/PPO).

  • Hands-on Experience with Deep Learning Models, especially Transformers.

  • Ability to translate cutting-edge research from papers into clean, production-ready code (Paper to Code).

  • Demonstrated experience with the full LLM/VLM training pipeline: data curation and preprocessing, distributed training across multi-GPU/TPU clusters, hyperparameter optimization, and model evaluation.

  • Proficient in Python with a strong track record of building substantial projects.

  • Solid foundation in computer science fundamentals (data structures, algorithms, design patterns).

  • BS degree in CS or related technical field.

  • Solid Experience with ML frameworks and libraries (PyTorch, TensorFlow).

  • Self-starter comfortable working in a fast-paced, dynamic environment.

Preferred Qualifications:

  • MS/PhD in CS or related technical field.

  • Familiarity with data processing stacks such as Spark and Airflow.

  • Experience with multi-node GPU training.

  • Contributor to open-source ML projects.

  • Deep knowledge in Linear Programming.

  • Experience with advanced NLP and Multimodal post-training experience (e.g., model distillation, quantization, deployment optimization).
