Summary We are looking for a .NET Desktop Developer with hands-on experience building and maintaining complex applications using .NET Framework 4.8 and Windows Forms. This role is dedicated to the continued development and improvement of our desktop-based accounting and billing software, so a background in financial applications (particularly A/R and billing) is highly desirable. You will work in a highly object-oriented environment, contributing to the long-term stability and performance of a mature application. This is not a typical full-stack or web development role—it requires a strong interest in Windows-based desktop solutions and the ability to navigate and understand large, existing codebases. Education Bachelor’s degree in Computer Science or a related field. Professional Experience 2+ years of hands-on experience in software development using .NET technologies. Key Responsibilities Develop and maintain desktop applications using .NET Framework 4.8 and WinForms. Work with complex accounting and billing logic, particularly around A/R functions. Troubleshoot and solve issues based on problem descriptions, often without predefined solutions. Read and understand legacy code; implement new functionality in a structured, object-oriented way. Collaborate with other developers and stakeholders to deliver stable, maintainable features. Continuously learn and understand the business logic of the application to propose effective solutions. Required Technical Skills 2–4 years of experience in desktop application development with .NET Framework and Windows Forms. Solid understanding of object-oriented programming and software design principles. Familiarity with accounting software concepts—especially billing and accounts receivable (A/R) logic. Ability to work through complex business problems and suggest appropriate technical solutions. Strong analytical and debugging skills in desktop environments. Experience with version control systems (e.g., Git, GitHub). Soft Skills Intermediate to advanced level of English proficiency. Eagerness to learn and explore new technologies. Strong communication skills and the ability to work well within a team. Effective time management and a proactive approach to task ownership. Nice to Have Exposure to legacy enterprise systems or large monolithic applications. Previous experience with accounting, ERP, or finance-related software. Understanding of performance optimization in Windows desktop applications. At Growth Acceleration Partners, we're an equal opportunity employer committed to building a diverse and inclusive team. We value everyone's unique background, and we provide equal opportunities regardless of race, color, creed, religion, sexual orientation, gender identity, age, national origin, disability, marital status, veteran status or any other personal right protected by law.
