Java Software Engineer

Job Title: Java Developer

Work Type: Onsite

Location: Houston, TX

Note: We are looking for local candidates or those who can relocate to Houston, TX. This role is open to USC and GC candidates only. We also welcome W2 candidates for this role.

Role Summary:

We are seeking a UI/UX‑focused Senior Java Developer with strong experience in Eclipse RCP and SWT to design and build high‑performance Java thick‑client applications. In this role, you will work closely with product managers, UX designers, and domain experts to deliver intuitive, responsive, and robust scientific desktop software used by geoscience professionals.

The ideal candidate brings deep expertise in desktop UI engineering using the Eclipse stack, combined with strong foundations in multithreading, concurrency, and core computer science principles. You will be responsible for implementing complex, long‑running algorithms off the SWT UI thread while ensuring a smooth and accessible user experience.

Key Responsibilities

• Design and develop rich desktop user interfaces using Eclipse RCP, including perspectives, views, editors, commands/handlers, and extension points, following established UI/UX design patterns (MVC/MVP, event‑driven architecture).
• Build modular and scalable applications using OSGi, ensuring clear component boundaries, clean service interfaces, and effective dependency management.
• Implement and extend context‑aware application behaviors, understanding how user actions propagate through Eclipse Commands, Handlers, Contexts, and the OSGi Service Registry.
• Develop and optimize multi‑threaded functionality, moving long‑running scientific computations off the UI thread using the Eclipse Jobs API, executors, and background tasks.
• Maintain UI safety and responsiveness by updating UI components through Display.asyncExec and syncExec.
• Ensure high performance and responsiveness when working with large datasets, including job scheduling, progress monitoring, cancellation handling, virtualized tables/viewers, and efficient rendering strategies.
• Apply software design patterns and domain‑driven design principles to produce modular, testable, and maintainable code.
• Collaborate with product and UX teams to translate complex scientific and geological workflows into intuitive, high‑signal user interfaces and iterate based on usability feedback.
• Write high‑quality, testable code with unit tests (JUnit) and UI automation tests (SWTBot); utilize profiling and diagnostic tools for performance and memory optimization.
• Participate in code reviews, architectural discussions, and CI/CD pipelines using Maven, Tycho, or Gradle.
• Contribute domain knowledge to data visualization, computational geometry, and mathematical features, including regression, derivatives, and geometric operations.

Required Skills & Experience :

• Strong proficiency in Java with hands‑on experience building desktop applications.
• Extensive experience with Eclipse RCP, SWT, and JFace.
• Solid understanding of OSGi frameworks, services, and module lifecycle.
• Expertise in concurrency, multithreading, and background processing in desktop applications.
• Experience designing UI/UX‑focused desktop solutions with performance and usability in mind.
• Strong foundation in computer science, mathematics, or physics, with the ability to implement complex algorithms.
• Familiarity with CI/CD pipelines and build tools such as Maven, Gradle, or Tycho.
• Experience with profiling, debugging, and performance optimization tools.

Nice to Have

• Exposure to scientific or geoscience applications.
• Experience with data visualization or computational geometry.
• Background in front‑end or UX‑centric development within desktop environments.
