AI/ML Engineer (Hybrid NLP + Classification)

South Geeks•Wyoming, NY

About The Position

We are looking for a part-time AI/ML Engineer to design and build the AI component of the platform: a hybrid rule-based plus ML system that maps contractor free-text into a 4-tier SAP catalog hierarchy, flags anomalies, and learns from operator corrections. The client is a Fortune 500 global energy company running a strategic initiative to migrate historical Plant Maintenance data into SAP S/4HANA through a governed, auditable web application integrated with SAP CPI. The work runs in 8 Agile-Scrum sprints over 16 weeks, fully remote, with a small senior team operating end to end. This is a 3-month engagement with 6 to 10 hours per week during active phases. The role requires Eastern Time overlap for gate and sprint reviews and is BYOD.

Requirements

NLP / text classification in Python (scikit-learn or HuggingFace transformers).
AI architecture documentation: a clean model design doc readable by non-technical reviewers.
Rule-based NLP (keyword extraction, regex, scoring logic).
ML classification pipeline (training data preparation, evaluation, tuning).
Anomaly detection in tabular data.
Python data science stack (pandas, numpy, scikit-learn, optionally spaCy).
Model feedback loop design.
API / microservice wrapping of an ML model.

Responsibilities

Author the AI/ML Architecture Design Document
Recommend an accuracy threshold for the catalog mapping engine.
Build the 4-tier catalog code mapping engine for SAP catalog types.
Implement the AI anomaly detection module.
Design and implement the "Train Model" feedback loop where operator corrections retrain the model.
Wrap the model as a microservice for the main app.
