Senior Software Engineer - 3D Mapping and Geospatial Systems/ Contractor

View full description

Requirements:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
• 5+ years of software development experience, with a focus on both front-end and back-end technologies.
• Proven experience with CesiumJS or similar 3D geospatial frameworks.
• Expertise in JavaScript, WebGL, and handling large datasets in real-time applications.
• Proficiency in creating custom map projections and working with libraries like Proj4.
• Strong understanding of terrain support and rendering performance optimization.
• Experience managing WebGL contexts to ensure efficient memory management.
• Knowledge of CesiumJS performance optimization techniques, such as batching polylines and icon management.
• Ability to handle rendering and interaction with large numbers of objects (e.g., polylines, icons) while maintaining high frame rates (50+ FPS).
• Proven ability to conduct performance testing and analysis, particularly in applications involving geospatial data.

Responsibilities:

• Collaborate with the team to implement custom map projections, including the Gnomonic projection, integrating libraries like Proj4 as needed.
• Optimize the creation and management of 10,000+ polylines with terrain support, ensuring performance goals are met (maintaining at least 50 FPS).
• Design and implement strategies for handling 10,000+ moving icons efficiently, optimizing both memory usage and performance.
• Ensure proper management of WebGL contexts to prevent memory leaks during the creation and destruction of map instances.
• Conduct performance analysis and propose optimizations to improve the visibility of icons and labels without compromising frame rates.
• Work closely with cross-functional teams to gather requirements, conduct feasibility studies, and deliver technical solutions for client projects.
• Actively participate in code reviews, architectural discussions, and collaborate on continuous improvement initiatives.
