What You’ll Be Doing

1. System Modernization & Architecture: Architect and develop a next-generation portfolio administration platform using C#, .NET 9, Blazor, and FluentUI. Refactor legacy WinForms code into a modular, scalable web-based system while enforcing industry-standard design patterns.
2. Data Integration & Automation: Design advanced ETL/ELT pipelines to consolidate broker, client, and market data from MySQL, REST APIs, and external financial providers. Optimize batch processing and asynchronous programming for efficiency.
3. User Interface & Web Development: Lead the creation of a responsive, intuitive web UI with dynamic data grids, inline editing, and validation using FluentUI components.
4. Quality Assurance & Continuous Improvement: Develop clean, testable code with comprehensive unit and integration tests. Collaborate in an Agile environment to refine system performance and mentor junior developers.
5. Stakeholder Engagement & Documentation: Partner with business teams to translate complex requirements into technical solutions and maintain detailed system documentation.

What We’re Looking For

1. Bachelor’s degree in Computer Science, Information Systems, or related field (or equivalent experience).
2. 5+ years of hands-on development experience with C#, .NET, and modern web technologies.
3. Demonstrated proficiency in building dynamic, interactive web interfaces (Blazor and FluentUI experience preferred, but consideration will be given to other front-end frameworks/systems).
4. Proven experience in designing and implementing RESTful APIs, repository patterns, and robust ETL processes.
