·       Build, test, deploy, and support scalable data pipelines and datasets using Databricks, Spark, SQL, Python/PySpark, dbt, Airflow, or similar tools.

·       Support batch and streaming data workloads, including ingestion, transformation, and consumption patterns for analytics and downstream systems.

·       Build reliable data products for reporting, analytics, AI/ML, and business operations based on business and architecture requirements.

·       Engineer Bronze, Silver, and Gold data layers in Databricks, following medallion architecture patterns where applicable.

·       Build and maintain transformation pipelines using dbt, Spark-based frameworks, and approved engineering standards.

·       Document solutions and improve pipeline performance, storage use, compute efficiency, and total cost to operate.

2. Quality and Support

·       Add automated tests, data-quality checks, monitoring, alerts, and clear error handling to improve data freshness, accuracy, and pipeline reliability.

·       Troubleshoot production issues, find the cause, and implement lasting fixes that reduce repeat incidents.

·       Support service levels and production readiness by making pipelines observable, testable, and easy to operate.

·       Use source control, code review, CI/CD, and release practices.

·       Participate in design and code reviews and share practical engineering practices with other engineers.

4. Analytics and Self-Service Enablement

·       Support semantic layers, aggregates, curated datasets, and performance improvements that help business users access trusted data.

·       Partner with architecture, analytics, and product teams to make data products easier to use, reuse, and support.

·       Support platforms such as Dataiku, Databricks, and Power BI where they are used for analytics and self-service delivery.

5. AI-Assisted Engineering

·       Follow access, encryption, privacy, retention, metadata, lineage, and stewardship requirements.

·       Build integrations across internal systems, external data sources, and cloud platforms using secure and reliable patterns.

·       Handle data in ways that meet company security, privacy, compliance, and audit expectations.

·       Work with Security, Privacy, Governance, Architecture, and Platform teams when standards are unclear.

4. AI-Assisted Engineering

·       Use approved AI tools, including Windsurf, Devin, and Databricks Genie where appropriate, to speed up coding, testing, debugging, documentation, data analysis, and routine engineering work.

·       Give AI tools clear context and requirements so generated code and recommendations fit the problem being solved.

·       Review, test, and understand AI-generated code before it is merged, deployed, or used in production.

·       Do not place restricted data, credentials, or confidential information into tools that are not approved for that use.

·       Follow company security, privacy, architecture, code-review, and responsible AI standards.

·       Share useful AI-assisted practices with the team and identify work that can be simplified or automated.

QUALIFICATIONS
Required

·       Bachelor’s degree in Computer Science, Engineering, Information Systems, or a related field, or equivalent experience.

·       Strong hands-on experience with the tools and practices used by the role.

·       Experience testing, documenting, and supporting production solutions.

·       Experience using AI-assisted development tools and validating AI-generated work.

·       5+ years in data engineering.

Preferred / Nice to Have

·       Experience with streaming, MDM, BI, semantic layers, or AI/ML data.

·       Experience building data products or curated data layers using Databricks medallion architecture.

·       Experience with observability, data quality tooling, performance tuning, and cost optimization for cloud data workloads.

·       Experience mentoring other engineers through code reviews, design reviews, or day-to-day technical guidance.
