Machine Learning Engineer

At Lyntris, we are building NLP capabilities that translate dense engineering documentation into structured, machine-actionable knowledge. This remote contract role centers on designing and delivering NLP pipelines and LLM-driven document understanding to extract meaningful information from manuals, specifications, and technical reports. The ideal candidate brings hands-on NLP experience and a technical degree, ready to work asynchronously with a cross-functional team.

Responsibilities

• Create and sustain NLP pipelines that tackle technical and structured documents, enabling information extraction, summarization, semantic search, and question answering.
• Develop and fine-tune transformer-based LLM applications, leveraging prompt design and retrieval-augmented generation (RAG) architectures.
• Process and analyze large technical corpora such as manuals, specifications, reports, drawings, tables, and figures.
• Craft methods to convert unstructured and semi-structured documents into structured knowledge for automated downstream use.
• Implement scalable ML solutions in Python using PyTorch and Hugging Face.
• Evaluate model performance, improve accuracy, and optimize inference pipelines for production environments.
• Collaborate with software engineers, data scientists, and domain experts to define requirements and deliver AI-enabled document intelligence solutions.
• Other duties as assigned.

Requirements

• Bachelor's degree in Computer Science, Data Science, AI/ML, or a related technical field, or equivalent hands-on experience.
• 2 to 4 years building NLP pipelines for technical or structured document understanding, including extraction, summarization, semantic search, and Q&A.
• Hands-on experience with large language models and transformer architectures (eg, BERT and successors), including fine-tuning, prompt engineering, pipeline orchestration, and retrieval-augmented generation (RAG).
• Experience processing engineering manuals, specifications, technical artifacts, tables, and figures.
• Strong Python skills and experience with PyTorch and Hugging Face Transformers.
• Proven ability to transform unstructured text into structured, machine-actionable knowledge.
• Must hold an active U.S. national security clearance or be able to obtain and maintain one.
