Contract Apple Machine Learning Engineer Jobs in Cumming, GA

ABOUT THIS POSITION

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.

WHAT YOU'LL NEED

• Bachelor's or Master's degree in Computer Science, Machine Learning, Artificial Intelligence, Statistics, or a related quantitative field. Ph.D. preferred.

• 5+ years of professional experience in machine learning engineering, with a strong track record of deploying and maintaining ML models in production environments.

• Expertise in programming languages such as Python (with extensive experience in ML libraries like TensorFlow, PyTorch, Scikit-learn).

• Deep understanding of machine learning fundamentals, including supervised, unsupervised, and reinforcement learning techniques, as well as deep learning architectures.

• Strong experience with cloud platforms (AWS, Azure, GCP) and their ML services.

• Proficiency in building and managing data pipelines using tools like Spark, Kafka, SQL, and NoSQL databases.

• Demonstrated experience with MLOps principles and tools (e.g., MLflow, Kubeflow, Sagemaker, Airflow).

• Excellent problem-solving skills and the ability to work independently on complex issues.

• Strong communication and interpersonal skills, with the ability to collaborate effectively in a cross-functional team.

• Experience in the healthcare technology domain is a significant plus.

• Proven ability to lead technical initiatives and influence architectural decisions.
