Job highlights

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
