Title: Data Engineer

Location: Woburn, MA

Job Details:

• Develop and maintain scalable ETL (Extract, Transform, Load) processes to efficiently extract data from diverse sources, transform it as required and load it into data warehouses or analytical systems.
• Design and optimize database architectures and data pipelines to ensure high performance, availability and security while supporting structured and unstructured data.
• Build and maintain robust ETL/ELT pipelines using Fabric Pipelines, Azure Data Factory, and Synapse.
• Implement secure data architectures using Roles-based Access Controls (RBAC), Key Vault, Private Endpoints
• Integrate data from APIs, third-party platforms, and hybrid (on-prem/cloud) systems.
• Develop data workflows using Python, SQL, and Spark, selecting appropriate frameworks based on workload characteristics.
• Drive cost-efficient, low-latency analytics through partition-aligned Delta storage, columnstore-optimized warehouse tables, DirectLake semantic access, and SCD-managed dimensional models, ensuring predicate pushdown, partition elimination, and minimal data movement across the query execution lifecycle.
• Implement secure data architectures using:
  • RBAC and row/column/object-level security (RLS/CLS/OLS)
  • Azure Key Vault, Private Endpoints, Managed Identities.
• Implement CI/CD pipelines for data platforms using Azure DevOps or GitHub
• Establish automated deployment, environment promotion, and testing strategies.
• Support downstream semantic models and reporting layers by delivering well-modeled, performant, and governed data structures (no report/dashboard development responsibilities).
• Partner with analytics and AI teams to deliver trusted, production-ready data products.
• Ensure platform reliability through constraint-driven data validation, fault-tolerant pipeline orchestration, and telemetry-backed observability, enabling anomaly detection, automated alerting, and lineage-driven root cause analysis across distributed data workloads.
• Lead design decisions and influence enterprise data architecture standards
• Collaborate with engineers, analysts, and business stakeholders to translate requirements into scalable solutions.
