We’re looking for a focused and experienced Software Developer to help maintain and evolve a mature, math- and data-intensive Windows application built on.NET Framework 4.8. The current product is a Windows client backed by a cloud-hosted SQL Server database (AWS), and we’re planning a strategic migration to a future web-based architecture. This role requires deep C# expertise, an eye for performance, and strong software engineering fundamentals-not a jack-of-all-trades, but a disciplined practitioner.

Responsibilities

• Maintain and enhance a.NET Framework 4.8 WinForms desktop application.
• Windows Communication Foundation.
• Optimize performance of MS SQL Server database.
• Hosting services on AWS.
• Ensure software meets GDPR compliance and cybersecurity best practices.
• Design and implement modern authentication approaches (OAuth2, OpenID Connect, etc.).
• Lead architectural planning and migration strategy for a future web-based application.
• Build or extend a CI/CD pipeline to improve testing and delivery workflows.
• Develop and maintain reusable code modules serving similar workflows across multiple user types.
• Produce clear, high-quality graphical outputs and data visualizations.
• Apply A/B testing and user feedback mechanisms to simplify and refine user workflows.
• Integrate AI-assisted tools to improve developer productivity.
• Utilize OpenCV or similar tools for image processing tasks as needed.
• Experience in Material UI, React or similar providing a modern web app experience.

Requirements

• 5+ years of professional experience in C# and the.NET ecosystem.
• Proficient in building Windows desktop applications using WinForms.
• Skilled in SQL Server development, performance tuning, and cloud-based deployments (preferably on AWS).
• Familiar with security compliance standards such as GDPR and secure coding practices.
• Experience with modern identity and access management (OAuth2, SSO, etc.).
• Strong architectural thinking, with experience planning migrations or long-term application transitions.
• Exposure to CI/CD tooling and implementation strategies.
• Comfortable analyzing and visualizing numerical data with graphical accuracy.
• Familiarity with OpenCV or similar image processing tools.
• Clear, pragmatic communication skills and team-oriented mindset.
