About the Team The Data Delivery and Operations Division partners with Investment Management, Operations, Risk, and Technology to deliver trusted, timely, and analytics-ready data. The Data Analytics Engineering team governs investment and reference data within the analytics environment. The team transforms source data into reliable data assets that support reporting, performance measurement, risk analysis, accounting, trading, and other investment platforms. Position Overview Reporting to the Manager, Data Analytics Engineering, the Senior Data Analytics Engineer is a senior individual contributor responsible for investment data solutions across security master, entity master, reference data, pricing, holdings, and related domains. This role requires a strong understanding of how securities and other investment assets are identified, classified, priced, and mastered. The Senior Engineer traces information through connected systems, diagnoses why data did not flow or transform correctly, and coordinates durable solutions with business teams, engineers, Technology, and external data providers.

Data Quality and Governance • Implement preventive and detective controls for timeliness, completeness, accuracy, validity, consistency, uniqueness, and referential integrity. • Monitor data-quality measures, investigate exceptions, perform impact analysis, and coordinate remediation. Solution Delivery and Technical Leadership • Lead complex initiatives and translate investment and operational needs into data models, transformation rules, validation requirements, test plans, and technical specifications. • Identify gaps in data architecture, controls, integration patterns, and support processes and recommend practical solutions. • Review solution designs, data models, SQL, Python, test plans, and documentation and provide clear, actionable feedback. • Mentor engineers in investment data, security mastering, pricing, statistical monitoring, troubleshooting, and engineering practices. • Lead discussions with key stakeholders across multiple business functions Qualifications • Bachelor’s degree in data analytics, data science, engineering, information systems, finance, or a related field. • 6+ years of progressive experience in analytics engineering, investment data management, data architecture, securities operations, or a related discipline. • Strong understanding of security and entity mastering, investment reference data, pricing, and how these data affect downstream investment processes. • Advanced SQL skills and working proficiency in Python • Hands-on Git experience, including branches, commits, pull requests, code reviews, and merge conflict resolution. • Experience with agile methodology workflow tools (Jira) • Experience using established CI/CD pipelines to test, promote, deploy, and validate changes.
