About the role


We are looking for an experienced software engineer to join a modernization program to migrate/rewire an existing application written in TAL to a modern C#/.NET implementation. The ideal candidate has hands-on experience with legacy application reengineering, strong TAL (or similar legacy language) knowledge, and proven C#/.NET development skills. You will be responsible for analysing legacy functionality, designing migration approaches, implementing core modules in C#, and ensuring a smooth cutover with minimal business disruption.


Key responsibilities


  • Analyse existing TAL codebase, data flows and business logic to produce migration plans and estimates.
  • Design and implement new services and modules in C#/.NET that replicate or improve legacy behaviour.
  • Work with architects, product owners and business SMEs to prioritize functionality for phased migration.
  • Convert/translate business rules, data structures and batch jobs from TAL into modern .NET components or microservices.
  • Create integration interfaces (APIs, messaging, ETL) and data migration scripts; validate data integrity.
  • Implement automated tests (unit, integration) and participate in CI/CD pipeline creation for the modernized application.
  • Troubleshoot and resolve defects during migration and post-go-live support.
  • Produce technical documentation and run knowledge transfer sessions for operations and support teams.
  • Ensure performance, security and maintainability of the new C# codebase.


Required qualifications & skills


  • 5+ years of professional software development experience.
  • Hands-on experience working with TAL (or equivalent legacy enterprise languages/environments).
  • Strong C# development experience (core .NET, .NET 6/7+ preferred).
  • Experience with application modernization / migration projects — analysis, code translation, re-architecture, or lift-and-shift.
  • Good understanding of relational databases (Oracle, SQL Server, MySQL) and SQL for data migration and validation.
  • Experience building and consuming APIs (REST/SOAP) and familiarity with messaging systems (MQ, RabbitMQ, Kafka — any).
  • Experience with source control (Git), CI/CD tools (Jenkins, Azure DevOps, GitHub Actions, etc.), and test automation.
  • Strong problem-solving skills and ability to interpret business requirements from legacy code.
  • Excellent written and verbal communication; able to explain technical tradeoffs to business stakeholders.


Nice to have


  • Experience with cloud platforms (Azure or AWS) and containerization (Docker, Kubernetes).
  • Knowledge of other legacy languages (COBOL, Natural/Adabas, TAL variants) or experience with mainframe/legacy environments.
  • Experience with refactoring to microservices, DDD, or event-driven architectures.
  • Familiarity with performance tuning and profiling tools.
  • Exposure to DevOps culture and IaC (Terraform, ARM templates).
