One of the world's largest providers of products and services to the energy industry has a need to develop and support enterprise information system in Oil & Gas domain.
Product being developed is a cloud solution for interpretation of geological and geophysical data. Project is based on SCRUM methodology.
Our project is stable, long-term and constantly adopts new technologies such as newest Java and Eclipse RCP versions, cloud and GPU computing, microservices architecture and other innovative frameworks.
Work supposes close cooperation with Customer team located in Houston and following Agile principles.
Our team is senior, supportive and friendly.

• 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.
  • Mentor junior developers and actively contribute to architectural and implementation decisions.
  • Embrace Agile/Scrum methodologies, delivering and demonstrating working solutions at the end of each sprint
  • Stay current with emerging technologies and trends in geophysical computing and software development.

• Mandatory Skills Description:

  6+ years of hands-on Java development experience
  Strong Java Core knowledge
  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
  Practical understanding of multithreaded programming: ability to implement concurrency in code directly, not only through third-party libraries
  Solid knowledge of design patterns and software architecture principles
  Ability to clearly articulate past projects, personal responsibilities, and concrete individual contributions
  Experience working in non-microservices, non-cloud-native development environments (desktop, embedded, or domain-specific platforms)
  Stable career trajectory, no fragmented job history with short tenures
