The Team

Deloitte’s Technology & Transformation: EAD: Engineering practice can help you uncover and unlock the value buried deep inside vast amounts of data. Our global network provides strategic guidance and implementation services to help companies manage data from disparate sources and convert it into accurate, actionable information that can support fact-driven decision-making and generate an insight-driven advantage. Our practice addresses the continuum of opportunities in business intelligence & visualization, data management, performance management and next-generation analytics and technologies, including big data, cloud, cognitive and machine learning.

Your work profile:

As a Consultant/Senior Consultant in our Technology & Transformation Team you’ll build and nurture positive working relationships with teams and clients with the intention to exceed client expectations: -

Design, develop and deploy solutions using different tools, design principles and conventions.
Configure robotics processes and objects using core workflow principles in an efficient way; ensure they are easily maintainable and easy to understand.
Understand existing processes and facilitate change requirements as part of a structured change control process.
Solve day to day issues arising while running robotics processes and provide timely resolutions.
Maintain proper documentation for the solutions, test procedures and scenarios during UAT and Production phase.
Coordinate with process owners and business to understand the as-is process and design the automation process flow.

Key skills required:

Design and develop Python-based automation frameworks and reusable utilities for ETL validation and data reconciliation.
Conduct end-to-end ETL testing, including source-to-target validation, transformation logic verification, and data completeness checks.
Write, review, and optimize SQL queries (joins, CTEs, window functions) to validate complex business rules and data transformations.
Execute Unix/Linux commands and shell scripts for ETL job monitoring, file validation, and log analysis.
Work with Mainframe systems for flat file validation, dataset checks, and job executions in ETL processes.
Test data warehouse components such as staging, fact, and dimension tables, including Slowly Changing Dimensions (SCDs).
Integrate automated validation into ETL CI/CD pipelines (Jenkins, GitHub Actions).
Collaborate with ETL developers, data modelers, and business analysts to investigate issues and ensure accurate data flow across banking systems.
Prepare test evidence, automation reports, and dashboards for traceability and coverage metrics.
Strong proficiency in Python (pandas, pyodbc, data comparison and validation frameworks).
Expertise in SQL — complex joins, aggregations, subqueries, and analytical functions.
Strong understanding of Oracle databases/datawarehouse and relational data modeling.
Proficiency in Unix/Linux commands (grep, awk, sed, shell scripting).
Basic knowledge of Mainframe systems for dataset handling.
Good understanding of Data Warehousing concepts — staging, data marts, fact/dimension modeling, and SCD handling.
Familiarity with test management tools (Rally, JIRA, Qtest) and CI/CD tools (Git, Jenkins).
