Machine Learning Engineer

Responsibilities: Own small to medium components of machine learning systems from technical design through implementation and delivery. Translate technical requirements into high-quality, maintainable code and deliver workstreams according to plan. Build and maintain data pipelines and feature engineering workflows to support machine learning and AI solutions. Design, train, evaluate, and refine machine learning models with minimal supervision, applying sound statistical and engineering practices. Implement ML solutions that can be deployed into production environments as microservices, APIs, batch jobs, or streaming components. Support production monitoring efforts by helping define and implement metrics for model performance, data drift, anomalies, and retraining triggers. Collaborate with Data Engineers, Software Engineers, Data Scientists, Product partners, and business stakeholders to deliver project objectives. Understand system design, data models, and technical artifacts well enough to contribute to implementation decisions and tradeoffs. Follow governance, documentation, coding, and source control standards consistently. Demonstrate flexibility and proactively support teammates with day-to-day responsibilities as needed. Clearly document and communicate work progress, technical decisions, and outcomes to technical and non-technical audiences.
