Data Engineer, Specialist

About Vanguard

Vanguard India

Vanguard’s office in India is a significant milestone in our global expansion. We are committed to establishing an enduring technology center in Hyderabad, Telangana and are excited to be adding talent who will focus on Artificial Intelligence (AI), mobile, and cloud-based technologies that drive our business outcomes and deliver a world-class experience for our clients.

Responsibilities:

• Build and operate production data pipelines on AWS — Glue (PySpark), Step Functions, Lambda, Athena, SNS, and S3 — from ingestion through transformation to reconciled, reportable output.
• Own operational support for production data pipelines, including monitoring, incident management, PagerDuty response, root cause analysis, and driving timely resolution of production issues while continuously improving platform reliability and observability.
• Develop and refactor transformation logic in PySpark, including migrating legacy Pandas/SQL logic and performance-tuning large-scale Spark jobs.
• Implement data reconciliation and sign-off — design recon checks (including parity between old and new implementations), investigate discrepancies to root cause, and produce the evidence the business needs to trust a run.
• Translate complex business and financial logic (asset classification, valuation and pricing rules, methodology calculations) into correct, testable, well-documented code.
• Take features through production readiness — pre-checks, access/role setup, environment promotion, and clear runbooks for ongoing support.
• Contribute to our cloud lakehouse migration — modelling refined tables, building repeatable ETL, and lifting reporting workloads onto a modern Delta/Databricks platform.
• Keep running pipelines healthy — monitor scheduled jobs, triage failures (partitioning, schema/data-type issues, backfills), and keep periodic (month-end / quarter-end) processing on time.

What we're looking for

Must have

• 5+ years in data engineering with strong Python and SQL.
• Hands-on PySpark / Spark for large-scale data transformation, including debugging and performance tuning.
• Production experience with AWS data services — Glue, Athena, S3, Lambda, Step Functions (or close equivalents on another major cloud).
• Solid data modelling skills and a rigorous, reconciliation-first approach to data quality.
• Ability to read a business or technical specification and turn it into correct, maintainable pipeline logic.
• Comfortable with Git-based workflows, CI/CD, and infrastructure-as-code.

Nice to have

• Databricks / lakehouse (Delta Lake) experience.
• Background in financial services — custody, fund accounting, unit pricing, or regulatory/financial reporting.
• Experience with access governance and IAM (e.g. role provisioning) and writing operational runbooks.
• Track record migrating legacy reporting or ETL onto modern cloud data platforms.
