GEMINI (www.geminimedicine.ca) is a Canadian hospital data and analytics platform that extracts, standardizes, and analyzes electronic health record data across more than 40 Ontario hospitals, representing approximately 60% of the province’s general internal medicine bed capacity. GEMINI is evolving as the Ontario node of VITAL, a pan-Canadian platform for real-time health data supporting clinical trials, AI, and learning health systems. VITAL enables secure, daily data refreshes, linkage and de-identification, and approved access for research, analytics, and innovation.

As part of this evolution, GEMINI is seeking a Manager, Data Operations to lead the maintenance of its existing data pipelines and the design, development, and operation of near-real-time data workflows. This is a highly technical role requiring solid technical expertise, attention to detail, and demonstrated experience in data management.

- Oversee and actively contribute to the design and optimization of data models, source-to-target mappings, and ETL/ELT pipelines that standardize multi-site clinical data into reliable analytics-ready datasets in near-real-time.
- Provide hands-on technical leadership for the design, development and review of high-volume, near-real-time data pipelines using SQL, Python, R, PostgreSQL, and Airflow, including change detection, reruns, exception handling, and audit logging.
- Lead technical decisions on PostgreSQL schema design, indexing, partitioning, materialized views, and query optimization for large joins, high-throughput processing, and near-real-time refreshes.
- Oversee application of strong software engineering practices using GitLab, GitHub, testing, code review, CI/CD,



documentation, and version control to improve reliability, maintainability, and reproducibility.
- Serve as the senior technical reviewer for architecture and platform standards, and produce and maintain architecture diagrams
