Java Developer

Role: Java Developer

Location: Plano, TX - Onsite

Duration: Fulltime / Contract

Job Description:

• We re seeking a UI/UXfocused Senior Eclipse RCP / SWT Engineer to design and build highperformance Java thickclient applications using Eclipse RCP, OSGi, SWT, and JFace. You will partner with product, UX, and domain experts to deliver intuitive, robust, and responsive scientific desktop software used by geoscience professionals. The ideal candidate combines deep desktop UI engineering with strong multithreading/concurrency and applied mathematics capable of implementing complex, longrunning algorithms off the SWT UI thread while maintaining a smooth, accessible user experience.

What you ll do

• Design & build rich desktop UIs with Eclipse RCP (perspectives, views, editors, commands/handlers, extension points) using SWT/JFace and established UI/UX patterns (MVP/MVC, eventdriven design).
• Implement OSGi modular architectures (bundles, services, dependency management), ensuring clean isolation between components and welldefined interfaces.
• Engineer contextaware behaviors across the application: understand and extend how actions (e.g., button press) propagate through Eclipse Command/Handler/Context and OSGi Service Registry to deliver predictable, traceable outcomes.
• Build and optimize multithreaded features: move longrunning scientific computations off the UI thread using the Eclipse Jobs API, executors, and background tasks; update UI safely via Display. asyncExec/syncExec.
• Ensure UI responsiveness & performance for large datasets: job scheduling, progress reporting, cancellation, virtualized tables/viewers, and efficient rendering.
• Apply software design patterns and domaindriven design to keep code modular, testable, and maintainable.
• Collaborate with product and UX to translate scientific/geology workflows into usable, highsignal interfaces; instrument and iterate based on usability feedback.
• Write clean, testable code with unit tests (e.g., JUnit), UI tests (e.g., SWTBot), and profiling/diagnostics for memory and performance.
• Participate in code reviews, architecture discussions, and CI/CD build pipelines (Tycho/Maven/Gradle as applicable).
• Contribute domain insights to data visualization and computational geometry/mathematics features (e.g., regression, derivatives, geometry operations).

Minimum qualifications (musthave)

• BS in Computer Science (or related) and 10+ years of professional software engineering experience.
• 7+ years building Java thickclient desktop applications with Eclipse RCP:
• Plugins/features/products, extension points, p2, perspectives/views/editors, Commands/Handlers/Contexts.
• Expertise in OSGi:
• Bundles, lifecycle, services, dependency injection/management, service tracking, modular isolation.
• Strong SWT/JFace:
• Layouts, events, custom widgets/controls, JFace viewers (Table/Tree), dialogs, wizards, actions.
• Advanced Core Java (Java 8+):
• Concurrency (threads, executors, futures, synchronization), collections, generics, streams, and design patterns (Factory, Strategy, Observer, Command, etc.).
• Proven multithreaded UI experience:
• Delivering longrunning computations without UI freezes; correct use of the SWT singlethreaded model and UI thread marshaling.
• Performance & scalability:
• Background jobs, cancellation, progress UI, memory/performance profiling, large dataset handling/virtualization.
• Applied mathematics for scientific applications:
• Calculus (including derivatives), geometry, statistical regression/line fitting, numerical methods; comfort validating algorithmic correctness and precision.
• Geology/Geoscience domain experience (or demonstrable experience rapidly acquiring complex scientific domains).
• Debugging & diagnostics:
• Event tracing across OSGi/Eclipse contexts, thread dumps, heap/CPU profiling, logging frameworks.

Preferred qualifications (nicetohave)

• Experience with computational geometry, coordinate systems, and scientific data visualization in desktop apps.
• Exposure to geospatial/GIS concepts (e.g., projections) and data formats.
• Knowledge of Tycho/Maven RCP build pipelines; p2 repositories, feature/product builds, update sites.
• Experience with SWTBot or similar UI testing frameworks.
• Familiarity with numerical libraries and precision/robustness techniques.
• Crosslanguage integration (e.g., JNI to C/C++ modules) or Python interop for scientific workflows.
