• 3+ years of professional software engineering, development, programming, or UI design experience.
• Strong willingness to learn and master Delphi and Object Pascal, and to develop a strong command of the Visual Component Library (VCL) framework.
• Direct, hands-on experience utilizing and configuring complex third-party grid, charting, and layout suites (e.g., DevExpress VCL, TMS Component Pack).
• Deep understanding of object-oriented programming (OOP) principles (e.g. Pascal, C++, Java, or C#), custom component design, object lifecycles, and native memory management.
• Proven track record of building data-dense software interfaces, including interactive charts, graphs, or schematics that handle real-time or calculation-heavy data streams.

Nice To Haves

• Delphi and Object Pascal experience is a strong plus; along with a strong command of the Visual Component Library (VCL) framework.
• Experience with FireMonkey (FMX) for cross-platform desktop compilation is a bonus.
• Background or familiarity working with scientific, industrial automation, CAD/CAE, or engineering simulation software is a plus.
• Experience interfacing desktop front-ends with relational databases or data extraction pipelines (Excel/COM integration) is also a bonus.

Responsibilities

• Design, develop, and maintain high-performance, pixel-perfect desktop graphical user interfaces (GUIs) for OGT’s software suite using Delphi and Object Pascal.
• Build, customize, and optimize visual layout components, data entry forms, interactive process flow diagrams (PFDs), and real-time scientific data plotting tools.
• Implement and maximize premium third-party VCL UI packages (such as DevExpress or TMS Software) to deliver a modern, enterprise-grade software look and feel.
• Partner closely with our core backend technical development team and chemical engineering experts to map underlying simulation engine outputs into clear graphical representations.
• Optimize desktop application responsiveness, ensuring efficient memory management, thread handling, and hardware acceleration across high-density data dashboards.
• Refactor legacy code structures where necessary to support modular UI scaling, write clean documentation, and eliminate memory leaks.

Benefits

• Highly competitive base salary commensurate with specialized Delphi training and resources.
• Full training resources and mentorship to master specialized Delphi/VCL engineering.
