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. The role combines investment data expertise with analytics engineering and applied statistical methods. The Senior Engineer uses SQL and Python, works within Git-based development practices, and uses established CI/CD pipelines to test and promote changes. This person must be able to learn unfamiliar tools, understand how they fit into SWIB’s data environment, and apply technology to a range of business and data problems. The position also provides technical guidance and mentoring to other analysts but does not have direct staff-management responsibility. Investment Data Mastering and Pricing • Serve as a subject matter expert for security master, entity master, reference data, pricing, holdings, and related investment data. • Interpret identifiers, classifications, instrument and issuer relationships, currencies, market conventions, corporate actions, price sources, valuation timing, and other attributes that affect investment processes. • Define and maintain source-selection, golden-source, and match and master rules for assigned data domains. Data Troubleshooting • Trace data from external providers through ingestion, mastering, transformation, validation, and downstream consumption. • Investigate securities, prices, identifiers, classifications, holdings, and other records that are missing, stale, duplicated, incorrectly mapped, or rejected. • Assess the business impact of data issues and coordinate resolution across Investment Management, Operations, Risk, ETL Engineering, Technology, and external providers. • Participate as needed in after hours on call rotation in case of critical data delivery failures • Identify recurring failure patterns and implement monitoring, validation, automation, or exception-handling improvements that reduce manual intervention.

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. Experience designing or administering CI/CD infrastructure is not . • Experience implementing data-quality controls, reconciliations, exception workflows, root-cause analysis, lineage, and governance practices. • Experience with cloud data platforms such as Snowflake, Microsoft Azure, or comparable technologies. • Ability to learn unfamiliar tools, select technology based on the problem, lead cross-functional work, and communicate with technical and investment audiences.
