Senior Java Developer (Saskatoon)

One of the world's largest providers of products and services to the energy industry has a need to develop and support an enterprise information system in the Oil & Gas domain. The product being developed is a cloud solution for interpretation of geological and geophysical data. The project is based on SCRUM methodology.

Our project is stable, long‑term and constantly adopts current technologies such as the newest Java and Eclipse RCP versions, cloud and GPU computing, microservices architecture and other innovative frameworks.

Work requires close cooperation with a customer team located in Houston and adherence to 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.
• 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 the 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

• 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.

Nice‑to‑Have Skills

• C++ development skills.
• Practical experience with the Eclipse RCP framework.
• OSGi knowledge.
• Oil & Gas domain experience.
