Responsibilities

Design frontend architecture: Help define and evolve the architecture of complex geospatial applications using React, TypeScript, and modern state management patterns.
Build geospatial visualizations: Develop high-performance mapping and visualization components using technologies such as OpenLayers, CesiumJS, WebGL, or related frameworks.
Work with large datasets: Create interfaces capable of displaying and interacting with substantial geospatial datasets, real-time feeds, and map layers.
Optimize application performance: Profile and improve rendering performance, memory usage, network activity, and interaction latency, including on hardware-constrained systems.
Develop data-intensive workflows: Use asynchronous programming, web workers, and efficient data-processing techniques to support demanding visualization and analysis workflows.
Integrate secure services: Partner 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 end users to create effective and intuitive mission-focused experiences.
Maintain engineering quality: Write maintainable, well-tested code; participate in design discussions and code reviews; and contribute to frontend standards and best practices.
Support team growth: Mentor junior and mid-level engineers and help establish development practices that improve quality, consistency, and delivery.
Contribute to technical direction: Evaluate tools and technologies, identify opportunities for improvement, and help guide the evolution of the application platform.
