• Develop mapping and visualization tools: Implement high-performance 2D and 3D mapping components using technologies such as OpenLayers, CesiumJS, WebGL, or comparable frameworks.
• Work with large datasets: Create interfaces capable of rendering and interacting with substantial geospatial datasets, real-time feeds, and multiple map layers.
• Optimize application performance: Identify and resolve rendering bottlenecks, memory issues, network inefficiencies, and interaction latency, including on hardware-constrained systems.
• Support data-intensive workflows: Use asynchronous programming, web workers, and efficient data-processing techniques to manage demanding visualization and analysis requirements.
• Integrate secure services: Collaborate with backend and DevOps engineers to integrate APIs, cloud-native services, authentication mechanisms, and secure data pipelines.
• Collaborate across disciplines: Work closely with UX and UI designers, product owners, systems engineers, and mission users to create effective and intuitive experiences.
• Maintain engineering quality: Write maintainable, well-tested code; participate in technical design discussions and code reviews; and promote frontend standards and best practices.
• Mentor and support teammates: Help mentor junior and mid-level engineers and contribute to a collaborative, high-performing engineering culture.
• Contribute to technical direction: Evaluate tools and technologies, identify opportunities for improvement, and help guide the evolution of the application platform.
