Database Engineering & Performance Optimization

  • Design and implement database schemas and data models as needed.
  • Write and tune complex SQL Server queries, stored procedures, and performance-critical data access patterns.
  • Diagnose and resolve performance bottlenecks across application and database tiers.
  • Build data-intensive solutions that interact with Snowflake and SQL Server as data sources

Application Migration & Modernization

Support the migration and modernization of one or more existing Python/Django applications hosted on Linux in Azure to a .NET Core target-state hosted on Azure App Services and Azure Web/API services.

  • Analyze existing Python/Django application architectures, including routing, controllers, business logic, and data access patterns.
  • Design and implement a target-state ASP.NET Core architecture in collaboration with Celanese IT resources.
  • Rewrite and refactor Python-based logic into native C# services, ensuring functional parity, performance, and long-term maintainability.

Support the migration and refactoring of existing DevExpress-based ASP.NET applications to modern UI architectures (React or native ASP.NET Core patterns).

  • Reduce reliance on proprietary UI components while preserving required functionality.
  • Improve application performance, usability, and extensibility.
  • Align legacy applications with modern development standards to ensure long-term supportability and scalability.

DevOps, CI/CD, and Azure Cloud Delivery

  • Contribute to CI/CD pipelines, DevOps practices, and Azure cloud deployments.
  • Support Azure best practices for configuration management, logging, monitoring, environment separation
  • Work within Azure DevOps tooling and support transition to GitHub workflows

Quality, Validation & Documentation

  • Maintain functional parity during migrations with automated testing and side by-side validation where appropriate
  • Support phased or incremental cutover strategies to reduce risk and downtime.
  • Produce technical documentation, including architecture decisions, migration approproaches/mappings, operational runbooks / support guides

Qualifications:

  • Bachelor’s degree in Computer Science, Information Systems, Engineering, or related field.
  • 5–7 years professional full stack development experience (front-end + back-end + database).
  • Microsoft certifications are a plus.

Nice to have previous experience in:

  • Python/Django → .NET Core migrations (or comparable cross-stack migrations) refactoring monolithic apps into service layers / clean architectures
  • DevExpress modernization: Refactoring DevExpress-based ASP.NET apps to modern UI stacks (React or ASP.NET Core patterns).
