This role will collaborate with Data Science, Engineering, Product, and our AI partners to bring predictive and generative capabilities into production at scale.

You will play a core engineering role in shaping the intelligence layer behind Nexus, Engage360, caregiver insights, emergency workflows, and member engagement.

Key Responsibilities

1. Model Development & ML Engineering

• Build, train, and optimize models for predictions such as churn, fall risk signals, emergency intent classification, and behavioral patterns.
• Implement NLP, embeddings, and LLM-based workflows for contextual understanding of transcripts, messages, and voice interactions.
• Develop real-time scoring services integrated with Azure Event Hub, Service Bus, and IOE rule engines.
• Design reusable, modular components for feature engineering, experimentation, and inference.

2. ML Ops & Deployment

• Build automated training, retraining, and evaluation pipelines in Databricks / Azure ML / Python.
• Develop CI/CD workflows for model deployment using Azure DevOps / GitHub Actions.
• Create scalable inference endpoints using Azure Functions, Container Apps, or APIM.
• Implement monitoring for model drift, data quality, and performance degradation.

3. Data Engineering for ML

• Work closely with Data Engineering to design robust data pipelines.
• Build feature stores, feature pipelines, and data transformations optimized for machine learning.
• Ensure traceability, reproducibility, and well documented data assets.

4. RealcTime Orchestration & Automation

• Integrate ML outputs into real-time orchestration flows.
• Contribute to the IOE decisionctree, scoring logic, and step orchestration.
• Build ML-driven triggers for automated campaigns, safety alerts, and proactive outreach.

5. Collaboration & Strategy

• Work with the Director of Data Science to define the ML roadmap for IOE.
• Partner with Product for personalization, engagement, and predictive feature development.
• Coordinate with Engineering to deliver API endpoints, event triggers, and user facing functionality.
• Contribute to documentation, experimentation logs, governance, and compliance.

Required Qualifications

• 2+ years of experience in Machine Learning, AI Engineering, or similar roles.
• Strong proficiency in Python, ML frameworks (scikit-learn, PyTorch, TensorFlow), and data libraries.
• Hands-on experience with cloud ML workflows (Azure preferred).
• Strong engineering fundamentals: APIs, containers, CI/CD, and distributed systems.
• Experience building and deploying models into production (batch + real-time).
• Understanding of NLP, embeddings, and LLM-based workflows.
• Candidates must be authorized to work in the United States without current or future need for visa sponsorship.
• Must have the ability to work from our Philadelphia office on Tuesdays and Wednesdays.

Preferred Skills

• Experience with Azure ML, Databricks, Delta Lake, Event Hub, Function Apps.
• Experience integrating ML with automation systems (n8n, Logic Apps, Make.com).
• Strong background in data quality, monitoring, and model governance.
• Experience working with healthcare, IoT, or emergency response data.
• Knowledge of prompt engineering, vector databases, or agentic AI workflows.
