Responsibilities

• Collaborate closely with geophysicists, data scientists, and software engineers to translate scientific domain requirements into robust on-prem or Cloud software solutions.
• Design, develop, and maintain high-performance applications for geophysical and geological data analysis, interpretation, and visualization (e.g., seismic, horizon, fault, velocity model, etc.).
• Present architectural designs and technical proposals to the architecture review board.
• Ability to break down development tasks and lay out clear implementation roadmaps.
• Implement and optimize computation algorithms.
• Design and develop both thin and thick client applications that interact with cloud-based microservices.
• Ensure high code quality through unit testing, code reviews, security hardening, and continuous integration with other domain tools.
• Provide technical support and lead user troubleshooting sessions to resolve issues and ensure smooth operation of DSG application.

Requirements

• Must have

  • 6+ years of hands-on Java development experience.

  • Experience with desktop development frameworks: Swing, SWT, or Eclipse RCP.
  • Proven experience designing and building complex systems end-to-end, not just maintaining or extending existing ones.

  • Solid knowledge of design patterns and software architecture principles.
  • Ability to clearly articulate past projects, personal responsibilities, and concrete individual contributions.

  • Stable career trajectory, no fragmented job history with short tenures.

• Nice to have

  • C++ development skills.
  • Practical experience with the Eclipse RCP framework.
