Machine Learning Engineer - LLMs

Hadrian Automation is seeking a Senior Machine Learning Engineer to lead the end-to-end machine learning lifecycle for language models designed to understand and reason over manufacturing data packages. The role centers on fine-tuned document understanding systems, annotation and active learning workflows, and evaluation frameworks that measure user impact.

Key Responsibilities

• Research, develop, and deploy fine-tuned language models for document classification, key information extraction, table parsing, and multi-page or document reasoning.
• Partner with the core engineering team to build and maintain annotation tooling, implement active learning loops, and design synthetic data augmentation strategies.
• Create evaluation frameworks that go beyond accuracy and CER, with precise measurement of system behavior and user impact.
• Collaborate with the machine learning team to set technical and product roadmaps for the AI platform.
• Reduce performance gaps in the long tail, where each incremental accuracy improvement translates to man-years of time savings at the company’s scale.

Required Qualifications

• 5-8 years of professional AI/ML experience, including at least 2 years working directly with large language models, such as fine-tuning, RLHF/DPO, or pre-training.
• Special consideration for experience with layout-aware models.
• Strong Python and PyTorch skills, including building custom training loops, loss functions, and data loaders from scratch when needed.
• Production deployment ownership, including shipping models to production and responsibility for endpoint and model health.
• MS or PhD in Computer Science, Electrical Engineering, or a related field preferred; equivalent industry experience valued equally.
