Senior Software Engineer

The Opportunity

Job Title: Senior Software Engineer (C#/.NET)

Location: Hyderabad, India (On-Site)

Employment Type: Hybrid

Definian is hiring experienced Senior Software Engineers to join our growing team in Hyderabad, India.

This is a ground-floor opportunity to join a high-impact modernization effort. The challenge: transforming decades of COBOL and C++ legacy code into modern C# not a simple translation, but a genuine reimagining of complex business logic using object-oriented design and contemporary best practices.

You'll be one of the first engineers on our India team, which means your contributions will be visible and your expertise will matter. This isn't a role where you'll be lost in a large organization or working on features no one uses. You'll develop deep knowledge of Applaud, become a go-to resource for production support during India hours, and collaborate closely with our India-based Software Architect and US technical leadership.

We are an AI-forward organization that embraces tools like Claude and Claude Code to accelerate development. You'll leverage these tools daily to work efficiently, solve complex problems, and participate in pioneering approaches to large-scale modernization.

This role demands strong C# skills, experience with modern UI frameworks, comfort with legacy codebases, and the persistence to debug complex issues in systems you didn't build. But for engineers who take pride in their craft and want to see their work have real business impact, this is the kind of challenging, meaningful work that accelerates careers.

What You'll Be Doing

• Develop and maintain features in Applaud using C#, .NET, and WPF
• Participate in the ongoing COBOL replacement initiative converting legacy components to modern C#
• Leverage Claude and Claude Code to accelerate development workflows and solve complex problems efficiently
• Troubleshoot and resolve production issues, providing India-hours support coverage
• Write clean, testable, well-documented code that others can maintain
• Participate in code reviews both giving and receiving constructive feedback
• Collaborate with the Software Architect to implement architectural decisions
• Work with databases to optimize queries and maintain data integrity
• Contribute to improving development processes, testing practices, and documentation
• Communicate effectively with US-based team members across time zones
• Participate in sprint planning, estimation, and daily standups

Required

• 4-6 years of professional software development experience
• Strong proficiency in C# and .NET (Core/.NET 6+ preferred, Framework experience acceptable)
• Experience with modern UI frameworks (WPF, WinForms, MAUI, Blazor, or similar)
• Experience with Visual Studio Professional
• Solid understanding of object-oriented programming principles and design patterns
• Experience with relational databases and SQL
• Experience with version control (Git)
• Ability to debug and troubleshoot complex issues in production systems
• Strong communication skills ability to work effectively with team members across time zones
• Ability to work in a hybrid environment (4 days in Hyderabad office)
• Graduate in Engineering or Bachelor of Science

Preferred Qualifications

• Experience with WPF (Windows Presentation Foundation) desktop application development
• Experience with DevExpress UI components
• Experience with Azure DevOps for source control, CI/CD, and work item tracking
• Experience with AI-assisted development tools, particularly Claude or similar LLM-based tools
• Understanding of prompt engineering and context engineering principles for effective AI collaboration
• Experience with legacy system modernization or migration projects
• Experience with unit testing frameworks (NUnit, xUnit, MSTest)
• Experience with AWS services
• Exposure to Python (not required, but helpful for cross-team collaboration)
• Experience with API development and integration
• Excellent communication and interpersonal skills
• Exceptional attention to detail
