Job Requirements
At Quest Global, it’s not just what we do but how and why we do it that makes us different. With over 25 years as an engineering services provider, we believe in the power of doing things differently to make the impossible possible. Our people are driven by the desire to make the world a better place—to make a positive difference that contributes to a brighter future. We bring together technologies and industries, alongside the contributions of diverse individuals who are empowered by an intentional workplace culture, to solve problems better and faster.
Role Overview
We are seeking a highly skilled Contract Software Developer with expertise in C++, Visual Basic (VB), and Fortran to support integration and modernization of legacy engineering or scientific applications into specifically ROMeo platform. The primary focus of this role is to develop and maintain C++ wrapper interfaces that enable interoperability between legacy Fortran or C++ codebases and newer applications, including desktop applications, VB-based front-end with automation tools like ROMeo.
The ideal candidate will also have strong experience in COM object development and integration, enabling robust communication between components in a Windows-based environment.
Key Responsibilities
- Design and develop C++ wrapper libraries to interface with existing desktop applications and legacy codebases.
- Enable seamless interoperability between Fortran/C++ computational modules and VB-based applications or miscellaneous desktop applications (standalone programs and ROMeo).
- Develop, integrate, and maintain COM objects/components for cross-language and application-level communication.
- Analyze existing legacy code (Fortran, VB, COM-based systems) and recommend modernization or optimization strategies.
- Write clean, maintainable, and well-documented code across multiple languages.
- Debug and troubleshoot issues related to:
- Cross-language data exchange
- COM interface interactions
- Memory management
- Performance bottlenecks
- Develop and execute unit and integration tests for wrapper and COM components.
- Collaborate with engineering and application teams to ensure functional and performance requirements are met.
- Produce clear technical documentation, including:
- API interfaces
- COM object specifications (interfaces, GUIDs, registration)
- Integration guides
- Code comments and system architecture
- Support deployment and integration into production environments.
Deliverables
- Fully functional C++ wrapper modules enabling integration between systems.
- Working COM components/interfaces supporting application interoperability.
- Updated and refactored VB and Fortran code where required.
- Comprehensive technical documentation.
- Test cases and validation results demonstrating system integrity.
We wholeheartedly believe in the diversity of thought that comes with fostering a culture rooted in respect, where everyone belongs, is valued, and feels inspired to share their ideas. We know embracing our unique differences makes us better, and that solving the worlds hardest engineering problems requires diverse ideas, perspectives, and backgrounds. We shine the brightest when we tap into the many dimensions that thrive across over 21,000 difference-makers in our workplace.
Work Experience
Required Qualifications
- Strong proficiency in C++, including:
- Object-oriented design
- Memory management
- Interfacing with external libraries
- Solid working experience with Fortran (77/90/95 or later).
- Experience with Visual Basic (VB6 and/or VB.NET).
- Demonstrated experience in cross-language integration (e.g., C++ ↔ Fortran, C++ ↔ VB).
- Hands-on experience with COM (Component Object Model) including:
- Creating and consuming COM objects
- Understanding of interfaces, GUIDs, and registration
- Familiarity with COM threading models and marshaling
- Familiarity with:
- DLL creation and linking
- Calling conventions (cdecl, stdcall)
- Interoperability techniques (e.g., COM, ISO_C_BINDING)
- Experience working in Windows Server 2019 or later environment.
- Strong debugging, problem-solving and testing skills in mixed-language environments.
Preferred Qualifications
- Experience working with legacy system modernization projects.
- Knowledge of numerical methods or engineering/scientific computing.
- Familiarity with Windows-based development environments (e.g., Visual Studio).
- Experience with build systems and compilers (e.g., MSVC, Intel Fortran, GNU).
- Understanding of performance optimization in high-compute applications.
