Hugging Face Jobs in Orem, UT (NOW HIRING)

ABOUT THIS POSITION
Job Description Summary
We are seeking a highly skilled and innovative Machine Learning Engineer with a passion for building robust, efficient, and domain-specific AI systems using Language Models (LMs) and agentic architectures. As a core member of the team, you will be instrumental in developing the entire ML pipeline, from sophisticated data extraction techniques to fine-tuning specialized LMs and orchestrating their interactions within a multi-agent framework.
This is a unique opportunity to apply state-of-the-art Generative AI and NLP techniques to a real-world, high-impact problem, leveraging the latest research in agentic AI and LMs to deliver economical and powerful solutions.
WHAT YOU'LL DO

• • Data Pipeline & Knowledge Base Construction:
  
  
  • Design, implement, and optimize robust pipelines for ingesting, parsing, and extracting structured information from complex documents (leveraging OCR, document layout analysis, Named Entity Recognition (NER), and Relationship Extraction (RE)).
  
  
  • Develop rich, nested JSON schemas for representing structured data and ensure scalable storage
  
  
  • Generate and manage high-quality vector embeddings for efficient retrieval-augmented generation (RAG) within a Vector Database.
  
  
  • Language Model (LM) Development & Fine-tuning:
  
  
  • Research, select, and experiment with appropriate open-source Language Models (Large & Small) (e.g., Phi-3, Mistral, Llama, Nemotron-H families) for specialized tasks.
  
  
  • Design and execute efficient fine-tuning strategies (e.g., LoRA, QLoRA, full fine-tuning) on curated, domain-specific datasets to achieve precise performance for tasks like coverage determination, code lookups, and policy rule application.
  
  
  • Explore and implement knowledge distillation techniques to transfer capabilities from larger models to smaller, more efficient LMs.
  
  
  • Agentic System Design & Implementation:
  
  
  • Build and maintain the core agentic framework, including the orchestrator that intelligently routes queries and coordinates interactions between various specialized LM tools.
  
  
  • Develop and integrate "tools" (specialized LMs and external APIs) that perform atomic medical necessity tasks, ensuring strict behavioral alignment and structured outputs.
  
  
  • MLOps & Deployment:
  
  
  • Deploy, manage, and monitor LMs and agentic components on Google Cloud Platform (GCP) using services like Vertex AI, GKE, Cloud Functions, and Cloud Run.
  
  
  • Implement robust MLOps practices for continuous integration, continuous delivery (CI/CD), model versioning, and performance monitoring (latency, throughput, accuracy).
  
  
  • Continuous Improvement & Research:
  
  
  • Establish effective feedback loops from end-user interactions and system logs to identify areas for model improvement.
  
  
  • Curate and expand training datasets, ensuring data privacy (PHI/PII masking) and legal compliance.
  
  
  • Stay abreast of the latest research in LMs, agentic AI, NLP, and document understanding, applying relevant advancements to our system.
  
  
  • Collaboration:
  
  
  • Work closely with subject matter experts, product managers, and other engineers to translate complex requirements into technical solutions and evaluate system performance.
  
  
  • Bachelor's or Master's degree in Computer Science, Machine Learning, Artificial Intelligence, or a related quantitative field.
  
  
  • 3+ years of professional experience in Machine Learning Engineering, with a strong focus on NLP.
  
  
  • Proven experience with Language Models (LMs), including model selection, fine-tuning, and deployment.
  
  
  • Strong proficiency in Python and familiarity with ML frameworks (e.g., PyTorch, TensorFlow, Hugging Face Transformers).
  
  
  • Solid understanding and hands-on experience with core NLP techniques and architectures, especially Transformers.
  
  
  • Experience with cloud platforms, particularly Google Cloud Platform (GCP), including services like Vertex AI, Cloud Storage, and compute services.
  
  
  • Familiarity with MLOps principles and tools for model serving, monitoring, and pipeline automation.
  
  
  • Excellent problem-solving skills, attention to detail, and ability to work independently and collaboratively.
  
  
  • Active use of artificial intelligence (AI) tools and techniques to enhance performance, drive innovation, and improve decision-making across business functions.
  
  
  • Ability to leverage AI tools and platforms to streamline workflows, improve decision-making, and drive innovation.
  
  
  • Curiosity and adaptability in exploring emerging AI technologies, with a mindset for continuous learning and experimentation.

WHAT YOU'LL NEED

• What Will Make You Stand Out (Preferred Qualifications):
  
  • Hands-on experience building or contributing to agentic AI systems or multi-agent frameworks.
  
  
  • Direct experience with document processing technologies such as OCR, layout parsing, Document AI, or custom information extraction from unstructured text.
  
  
  • Experience with Vector Databases (e.g., pgvector, Pinecone, Weaviate, Qdrant) and RAG architectures.
  
  
  • Exposure to the healthcare domain, particularly understanding medical terminology, CPT/ICD codes, or regulatory documents.
