• Experience with Autosys/Airflow or similar orchestration tools.
• Working knowledge of REST APIs, Object Storage, Dremio, and CI/CD pipelines.
• Strong troubleshooting and problemsolving capabilities.
• Solid foundation in data modeling (conceptual/logical/physical) and database design.
• Platform & DevOps
• Cloud-native engineering experience - serverless, managed Spark, event-driven architectures.
• Familiarity with containerization (Docker, K8s) and workflow operators.
• Strong experience implementing test automation for data pipelines (unit, contract, integration tests).
• Data Lakehouse & Storage
• Handson with optimization techniques: clustering, Zordering, vectorized IO (Parquet/ORC), compaction.
• Experience implementing Medallion architectures and governed ingestion zones.
• Advanced Data Engineering
• Experience architecting pipelines using distributed systems patterns (shuffle optimization, spill, broadcast, storage layouts).
• Experience with streaming frameworks like Spark Structured Streaming or Apache Flink.
• Data Quality & Governance
• Knowledge of data governance platforms (Collibra, Alation, Purview).
• Understanding of financial data controls, validation rules, reconciliation checks, and compliance (SOX/PCI).
• Experience implementing lineage, observability, drift detection.
• GenAI for Data Engineering
• Applying GenAI for metadata extraction, data anomaly detection, automated documentation, or pipeline optimization.
• Domain Expertise
• Exposure to financial risk, treasury functions, or Asset & Liability Management (ALM) processes.

Job Expectations:

• Deliver high-quality engineering outcomes during Data Center exit migrations and DPC onboarding, ensuring validations, automation, and production readiness.
• Collaborate with cross-functional teams to build scalable, highperformance data solutions using Python, SQL, Spark, Iceberg, Dremio, and Autosys.

Data Engineering & Pipeline Development

• Design, build, test, deploy, and maintain large-scale structured and unstructured data pipelines using Python, SQL, Apache Spark, and modern data lake/lakehouse technologies.
• Develop and optimize metadata-driven pipelines, wrappers, ingestion frameworks, and validation layers to support CALM data workflows.
• Build and maintain high-quality ELT/ETL pipelines following best practices in reliability, performance, observability, and reusability.

Distributed Computing & Lakehouse Engineering

• Engineer and optimize Spark pipelines for largescale batch and streaming workloads (partitioning, caching, Catalyst optimization, AQE, Tungsten).
• Work with open table formats such as Iceberg, Delta, or Hudi for versioned data, time-travel, compaction, and schema evolution.
• Implement Medallion (Bronze/Silver/Gold) architecture patterns for modern lakehouse systems.

Data Quality, Testing & Observability

• Implement automated data quality frameworks using tools such as Great Expectations / Deequ or custom validators.
• Build data health monitoring frameworks with SLAs/SLOs, anomaly detection, and lineage capture.
• Ensure strong validation layers during Data Center exits, migration programs, and DPC onboarding.

API & Microservice Development

• Build RESTful and metadata APIs using Python frameworks (FastAPI/Flask) to enable secure, governed data access.
• Collaborate with application teams to integrate data access patterns and platform services.

Cloud & Platform Engineering

• Design and deploy data pipelines in cloud platforms (AWS, Azure, GCP) leveraging managed compute, orchestration, and storage.
• Build CI/CD workflows and infrastructure automation using Jenkins, GitHub Actions, Azure DevOps, Terraform, or Helm.
• Apply secure engineering principles including IAM, secrets management, encryption standards, and network controls.

Orchestration & Scheduling

• Build resilient orchestration flows using Autosys or equivalent tools.
• Apply modular design with retries, alerts, SLAs, and workflow dependency management.

Collaboration & Delivery

• Work with cross-functional Agile teams (Product, Architecture, QA, Treasury SMEs).
• Analyze technical requirements, evaluate design alternatives, and provide recommendations aligned with enterprise standards.
• Independently deliver complex engineering tasks and contribute to architecture/roadmap discussions.
