We are seeking a highly analytical and data-focused Senior Software Engineer to play a pivotal role in our upcoming platform migration.

This is a high-impact, data-intensive role requiring deep expertise in relational databases (Microsoft SQL Server and Sybase), complex data transformation, and meticulous data validation. You will work extensively with large datasets-including Index Histories-ensuring absolute data integrity, accuracy, and consistency as we modernize our technology stack.

While prior financial index knowledge is a bonus, your ability to reverse-engineer legacy systems, map complex data models, and build robust migration solutions is essential.

Req.#1105387855

Responsibilities

• Migration Leadership: Lead and contribute to the end-to-end migration of index configurations and historical data from legacy platforms to the current BAU platform

• System & Data Analysis: Analyse existing index configurations and data structures to understand their mechanics and define the optimal migration strategy

• Data Transformation: Translate and convert configurations across different data models while strictly maintaining business requirements and data integrity

• Database Engineering: Leverage Microsoft SQL Server and Sybase to investigate, analyse, transform, validate, and move large-scale datasets (including Index Histories)

• Data Quality & Reconciliation: Perform detailed data validation and reconciliation to guarantee that migrated data is complete, accurate, and consistent. Identify data quality issues, root causes, and implement robust fixes

• Development: Write efficient, scalable SQL queries, stored procedures, and data transformation processes suitable for a production environment

• System Investigation: Explore existing applications and legacy systems to understand how data and configurations are processed

• Collaboration & Communication: Work closely with business analysts, engineers, and stakeholders to clarify requirements, resolve migration roadblocks, and communicate complex technical findings to both technical and non-technical audiences

• Continuous Improvement: Contribute to the automation, testing, and optimization of migration processes while mentoring and sharing knowledge with fellow engineers

Requirements

• Experience: 8+ years of professional experience in software engineering, data engineering, application development, or a closely related technical discipline

• Database Expertise: Strong, hands-on experience with Microsoft SQL Server and Sybase

• SQL Mastery: Advanced SQL skills, including complex queries, stored procedures, data analysis, and performance optimization

• Big Data Handling: Proven experience working with large, data-intensive, and complex datasets

• Analytical Mindset: Exceptional problem-solving skills with a track record of independently investigating unfamiliar systems, reverse-engineering data models, and designing mapping/transformation strategies

• Migration Experience: Demonstrated hands-on experience with data migration, transformation, reconciliation, or legacy-to-modern modernization projects

• Quality Focus: An uncompromising focus on data quality, accuracy, and integrity

• Environment: Experience working in an Agile software development lifecycle

• Soft Skills: Outstanding communication and interpersonal skills, with the ability to explain technical concepts clearly to diverse stakeholders

Nice to have

• Experience within Index Management, financial indices, or broader financial markets

• Knowledge of index configuration and index lifecycle processes

• Experience with C# / .NET and familiarity with .NET applications

• Familiarity with UI technologies (Angular, JavaScript, HTML/CSS)

• Experience with PostgreSQL

• Exposure to cloud platforms such as AWS

• Experience with automated testing, CI/CD pipelines, Python, or Java/Spring Boot
