Digital Factory - Data Engineer Assistant Director
At EY, were all in to shape your future with confidence.
Well help you succeed in a globally connected powerhouse of diverse teams and take your career wherever you want it to go.
Join EY and help to build a better working world.
The opportunity
The Data Engineer provides strategic, technical, and operational leadership for the design, delivery, and operation of enterprisegrade data platforms that underpin EYs digital products, analytics, and datadriven transformation initiatives.
This role goes beyond handson delivery to owning data engineering outcomes endtoend, shaping platform strategy, setting standards, and leading teams to deliver scalable, reliable, secure, and compliant data solutions in highly regulated environments.
You will act as a trusted technical leader and advisor to Product, Architecture, Analytics, Data Science, and senior stakeholders, ensuring data platforms are fit for purpose, futureproof, and aligned with EYs broader technology and risk strategy.
Key Responsibilities
Data Platform Strategy & Technical Leadership
- Define and drive the data engineering strategy and roadmap aligned with product, analytics, and enterprise architecture objectives.
- Own the technical vision and target architecture for data platforms (lakehouse, warehouse, streaming, and eventdriven patterns).
- Make and govern architecture decisions, balancing scalability, cost, performance, security, and regulatory requirements.
- Act as the design authority for complex data pipelines and platforms, reviewing and approving solution designs.
Advanced Data Platform & Pipeline Engineering
- Oversee the design and implementation of enterprisescale batch and streaming data pipelines, using Python and modern data frameworks.
- Ensure robust ingestion, transformation, and serving layers across internal and external data sources (APIs, databases, files, events).
- Drive the development of reusable data engineering frameworks, accelerators, and reference implementations.
- Establish and enforce data contracts, schemas, versioning strategies, and documentation standards across teams.
Data Quality, Reliability & Operational Excellence
- Set and own data quality, reliability, and observability standards across all managed data products.
- Define and govern SLAs/SLOs for critical data assets, ensuring businesscritical use cases are protected.
- Lead major incident management and rootcause analysis, ensuring durable, systemic fixes rather than tactical workarounds.
- Embed testing strategies (unit, integration, data quality, regression) as nonnegotiable engineering standards.
Performance, Scalability & Cost Governance
- Ensure platforms and pipelines are designed for scale, resilience, and fault tolerance (idempotency, retries, checkpointing, backpressure).
- Drive continuous optimization of compute usage, storage layouts, query performance, and costs.
- Make datadriven tradeoff decisions between performance, cost, complexity, and maintainability.
People Leadership & Team Enablement
- Provide technical leadership, mentoring, and coaching to Data Engineers across multiple teams or initiatives.
- Set clear expectations for engineering quality, delivery discipline, and professional development.
- Support capacity planning, skill development, and succession planning within the data engineering capability.
- Act as an escalation point for complex technical and delivery challenges.
CrossFunctional & Stakeholder Collaboration
- Partner closely with Product, Architecture, Backend Engineering, Analytics, and Data Science leads to translate strategic objectives into executable data solutions.
- Engage senior stakeholders to explain technical tradeoffs, risks, and investment needs in clear, businessaligned language.
- Ensure data platform decisions support downstream consumption patterns (APIs, analytics, ML, operational use cases).
Security, Privacy, Risk & Compliance Ownership
- Own the implementation and governance of securebydesign data engineering practices (access controls, encryption, secrets management).
- Ensure platforms comply with enterprise, regulatory, and privacy obligations (data classification, lineage, retention, auditability).
- Act as a key contributor to audits, risk assessments, and data governance forums, representing the data engineering domain.
Operations, Governance & Continuous Improvement
- Hold accountability for production data platforms, ensuring operational stability, availability, and ongoing improvement.
- Reduce operational risk and toil through automation, standardization, and platformlevel capabilities.
- Define, maintain, and evolve data engineering standards, guardrails, and best practices across the Digital Factory.
- Contribute to broader technology governance and platform strategy at program or portfolio level.
Qualifications Required
- Bachelors or Masters degree in Computer Science, Data Engineering, Software Engineering, or a related discipline.
- Extensive professional experience in data engineering, including leadership or solutionownership responsibilities.
- Deep expertise in Python for largescale, productiongrade data engineering.
- Strong command of SQL and data modeling (dimensional, normalized, lakehouse, or hybrid patterns).
- Proven experience designing and operating enterprise data platforms (data lakes, warehouses, analytical stores).
- Solid experience with CI/CD, automated testing, code quality, and engineering governance for data workloads.
- Strong understanding of cloud platforms and data services (Azure strongly preferred).
- Demonstrated ownership of data security, access control, observability, and operational reliability.
Preferred
- Strong handson and design experience with modern data ecosystems (e.g., Spark, Databricks, Airflow, dbt, Azure Data Factory).
- Experience with streaming and eventdriven architectures (Kafka, Azure Event Hubs, Service Bus).
- Prior ownership of lakehouse or enterprise data warehouse strategies.
- Experience operating in financial services or other regulated environments.
- Familiarity with infrastructureascode (Terraform, Bicep) and platform automation.
- Proven success working across distributed, crossfunctional, and global teams.
