Structuring the technical vision for an employee virtual assistant into a clear, actionable implementation roadmap.
Defining and enforcing boundaries between Python micro-services to maximize team efficiency and parallel development.
Collaborating with Data Scientists to design solutions that meet production constraints, including infrastructure selection, data ingestion, and API design.
Automating ML pipelines for seamless integration and deployment, including Docker/VM image creation and comprehensive testing (unit, regression, integration).
Supporting Data Scientists in leveraging industrial CI/CD tools for building and monitoring AI services.
Partnering with IT Production to parameterize and optimize target environments.
Ensuring models run reliably in production, are retrained as needed (including automated retraining), and are monitored from both IT and business perspectives.
Championing best practices in code, model, and data versioning, and sharing knowledge across the chapter.
Facilitating communication between AI, Analytics, and IT teams to ensure robust deployment and monitoring of ML models.
What We’re Looking For
At least 6 years of relevant experience in Machine Learning Engineering or related fields.
Master’s degree in Computer Science or equivalent experience.
Proven expertise in Python micro-services, containerization, and cloud computing services.
