Machine Learning Engineer - LLMs

About this role

Hadrian seeks a Senior Machine Learning Engineer to own the ML lifecycle for language models that extract and reason over manufacturing data. You'll develop fine-tuned models for document classification, information extraction, and multi-document reasoning to automate Design for Manufacturing analysis in autonomous factories.

What you'll do

• Research, develop, and deploy fine-tuned language models for document classification, key information extraction, and table parsing
• Build and maintain annotation tooling, implement active learning loops, and engineer synthetic data augmentation strategies
• Develop evaluation frameworks that quantify system behavior and user impact beyond standard accuracy metrics
• Collaborate with the ML team to set technical and product roadmaps for the AI platform
• Own model deployment to production and maintain endpoint and model health
• Optimize accuracy improvements to maximize time savings across manufacturing operations at scale

What they're looking for

• Large language model fine-tuning and RLHF/DPO techniques
• Python and PyTorch (custom training loops, loss functions, data loaders)
• Production ML deployment and model monitoring
• Document understanding and layout-aware model experience
• Annotation tooling and active learning frameworks
• Synthetic data generation and augmentation strategies
• Evaluation framework design for NLP/vision systems
• CAD/CAM data processing (preferred)

Benefits

• Medical, dental, vision, and life insurance
• Equity participation in a well-funded startup
• Opportunity to impact critical aerospace and defense manufacturing
• High-ownership role in a fast-growing company
• Expansion into new facilities and product lines
