Remote Senior Software Engineer, 3D Mapping and Geospatial Systems

Summary

Join Janea Systems (USA) as a Senior Software Engineer - 3D Mapping and Geospatial Systems to deliver cutting-edge solutions for complex engineering challenges. This role involves working on custom software engineering projects, such as supporting custom projections, optimizing performance for large-scale data sets, and ensuring memory efficiency in a high-performance application.

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

Preferred Qualifications

• Familiarity with geospatial data and mapping applications
• Hands-on experience with CesiumJS, including the creation and destruction of multiple map instances without memory leaks
• Experience in real-time systems, including handling and updating large numbers of polylines and icons efficiently
• Knowledge of optimization strategies for improving icon and label visibility without compromising on performance

Benefits

• Competitive compensation with benefits, paid vacation, and sick leave
• Ultra-flexible working conditions – we provide a generous office equipment allowance so you can work from home, we can also provide you with a desk at an office/coworking facility near you, or use both. No business travel necessary
• An enjoyable, start-up work environment, with excellent opportunities for professional growth and development
• Flexible working hours – as a remote-first company, our focus has always been on getting the job done well, not when or where it gets done
