Machine Learning Engineer (LLMs Job Torrance area,California USA,Software Development

Position: Machine Learning Engineer (LLMs)

Copilot is our system for automating Design for Manufacturing (DFM) analysis and generating manufacturing processes
We work directly with some of the best operators in the world to identify high-impact opportunities to automate and augment with software
Our team owns problems end-to-end: we design the software, define the manufacturing processes, and ensure they can be executed reliably in our factories
The work spans computational geometry, CAD/CAM integrations, high-performance systems, and full-stack web tooling
We execute whatever is required to deliver a working solution and best serve our users
The DFM team within copilot is building the manufacturing data intelligence layer that serves as the tip of the spear for our automation stack
This platform ingests, interprets, and reasons over the full spectrum of manufacturing data (mechanical drawings, quality documentation, CAD data) and transforms it into structured, actionable information for the factory
As a Senior Machine Learning Engineer, you will own the ML lifecycle for the language models that understand and reason about the content in manufacturing data packages
Research, develop, and deploy fine‑tuned language models for document classification, key information extraction, table parsing, and multi‑page/document reasoning
Work alongside the core engineering team to build and maintain annotation tooling, implement active learning loops, and engineer synthetic data augmentation strategies
Develop evaluation frameworks that extend beyond accuracy and CER, precisely quantifying system behavior and user impact
Collaborate with the other members of the machine learning team to set the technical and product roadmaps for the AI platform
Burn down the long tail, as every percentage point of accuracy maps to man‑years of time savings at our scale
