Machine Learning Engineer

About Comprehensive Rehab Consultants (CRC)

Comprehensive Rehab Consultants partners with skilled nursing facilities to improve clinical quality, efficiency, and financial performance. CRC is recognized as an innovator in the post-acute care space, developing new AI-driven care and revenue models that decrease hospitalizations and improve outcomes.

We are seeking a Machine Learning Engineer to drive the next generation of CRC’s AI platform. This role is engineering-heavy, focused on building, tuning, and deploying scalable ML/NLP/LLM systems that power our clinician tools, financial analytics, contract modeling, DFS/PDPM engines, readmission risk scores, and enterprise analytics chatbot.

Role Summary

You will design, optimize, and productionize machine learning systems using CRC’s full internal data environment. This includes tuning an existing NLP engine, developing statistical/ML models (including ordered probit and regression-based DFS calculator), building internal LLMs trained on CRC documents, and developing the AI analytics chatbot used by all business units.

This role requires someone who ships ML systems—not someone who just builds notebooks.

Key Responsibilities

Machine Learning & Statistical Modeling

Build, tune, and validate statistical models including multi-stage regression, ordered probit, and generalized linear models, audit automation, acuity scoring, and financial forecasting
Engineer features from structured and unstructured healthcare data (EMR, claims, revenue cycle, clinician notes)

NLP & LLM Engineering

Tune the existing CRC NLP engine for clinical note understanding, keyword extraction, concept expansion, negation detection, and sentiment scoring
Build custom clinical embeddings using HuggingFace Transformers, spaCy, and domain-tuned vector models
Develop and maintain a CRC private LLM, trained on internal knowledge bases, documentation, analytics logic, and care guidelines
Build automated pipelines for LLM evaluation, retraining, retrieval-augmented generation (RAG), and grounded QA

AI-Driven Product Development

Architect, build, and deploy the AI Analytics Chatbot, integrating model logic, business rules, and Fabric/Databricks data sources
Integrate ML models into production services using notebooks, APIs, or batch inference jobs
Support creation of AI-generated reporting, insights summaries, and automated clinical/financial narratives

MLOps & Engineering

Build maintainable ML pipelines (training, validation, deployment) using Databricks, Fabric, MLflow, GitHub, and CI/CD
Implement model monitoring, drift detection, and automated retraining
Package and deploy reproducible models via APIs or scheduled Fabric/Databricks workflows

Collaboration & Delivery

Work with data engineering to embed models into CRC applications
Partner with BI analysts to transform model outputs into dashboards
Document methodologies, assumptions, architecture, and validation processes clearly

Required Skills & Experience

3–6 years of hands-on machine learning engineering experience (not just DS notebooks)
Strong Python engineering background:
pandas, scikit-learn, statsmodels, PyTorch or TensorFlow, transformers, spaCy
Experience building and tuning LLM and NLP pipelines end-to-end
Experience with regression, ordered probit/logit, hierarchical models, and general statistical modeling
Experience deploying ML workloads in Databricks, Azure ML, and Fabric
Strong SQL for feature engineering and model validation
Prior experience working with healthcare data (EMR, claims, RCM, CMS) preferred
Strong communication and the ability to explain complex ML systems to non-technical stakeholders.
Proactive, self-managing engineer who can independently own ML systems end-to-end.
Fluent English required

Preferred Qualifications

Experience with:
Retrieval-Augmented Generation (RAG) pipelines
Vector databases (FAISS, Chroma, Pinecone, Qdrant)
Enterprise chatbot frameworks
MLflow, CI/CD, GitHub Actions, and model versioning
Power BI integration for ML outputs
FHIR/SMART on FHIR

Certifications considered:

Databricks ML Associate/Professional
Azure AI Engineer Associate
DeepLearning.AI NLP/LLM specializations
