This Opportunity

We are seeking an experienced Senior Software Developer with a passion for crafting high-performance web applications and transforming complex legacy systems. In this role, you will drive the architectural design and development of our next-generation fund administration software using C#, Blazor, and Fluent UI. Your expertise will be pivotal in modernizing our codebase, integrating diverse financial data sources, and delivering a responsive, intuitive user experience that drives Opus fund administration forward.

  • Refactor and migrate legacy WinForms code into a modular, scalable, and maintainable web-based system.
  • Establish and enforce industry-standard design patterns (e.g., Repository, Dependency Injection) and coding best practices.

Data Integration & Automation:

  • Design and implement advanced ETL/ELT pipelines to consolidate broker, client, and market data from various sources such as MySQL databases, REST APIs, and external financial data providers.
  • Develop robust data transformation processes with comprehensive error handling and audit trails.
  • Optimize batch processing and leverage asynchronous programming techniques to ensure efficient data handling and concurrency.

User Interface & Web Development:

  • Lead the creation of a modern, responsive web UI that delivers seamless navigation and interactive data experiences.
  • Develop rich, user-centric, and intuitive interfaces with features like dynamic data grids, inline editing, and comprehensive validation using FluentUI components.

Quality Assurance & Continuous Improvement:

  • Write clean, testable code and develop comprehensive unit and integration tests using MSTest or similar frameworks.
  • Work in an Agile environment, collaborating with cross-functional teams to continuously refine system performance, usability, and reliability.
  • Mentor junior developers, fostering a culture of learning, innovation, and technical excellence.

Stakeholder Engagement & Documentation:

  • Collaborate with business stakeholders, data analysts, and other team members to translate complex requirements into effective technical solutions.
  • Produce and maintain detailed documentation covering system architecture, code modules, data pipelines, and integration strategies.

A Little About You

  • You have a bachelor's degree in Computer Science, Information Systems, or a related field, or equivalent professional experience.
  • You have at least 5 years of hands-on development experience with C#, .NET, and modern web technologies.
  • You demonstrate proficiency in Blazor and FluentUI for building dynamic, interactive web interfaces.
  • You have proven experience in designing and implementing RESTful APIs, repository patterns, and robust ETL processes.
  • You have a strong command of SQL and familiarity with MySQL or SQL Server.
  • You have experience with version control systems (e.g., Git) and Agile/DevOps methodologies.
  • You have expertise in unit testing frameworks (e.g., MSTest, NUnit) and continuous integration practices.
  • You have excellent problem-solving abilities and a track record of architecting scalable, high-performance systems.
  • You can effectively communicate and liaise with both technical teams and business stakeholders.
  • You can produce clear, concise technical documentation and user guides.
  • You have experience with legacy system migration and refactoring is a significant plus.
