How much do cesium js jobs pay per hour?

As of Aug 20, 2026, the average hourly pay for cesium js in the United States is $59.30, according to ZipRecruiter salary data. Most workers in this role earn between $53.37 and $66.11 per hour, depending on experience, location, and employer.

What is CesiumJS?

CesiumJS is an open-source JavaScript library for creating 3D globes and maps in a web browser without needing a plugin. It allows developers to visualize geospatial data with high performance using WebGL, supporting features like terrain, imagery layers, 3D tiles, and time-dynamic visualization. CesiumJS is widely used for applications in fields such as geospatial analysis, urban planning, and simulation, enabling interactive and immersive experiences with real-world data.

What are the key skills and qualifications needed to thrive as a Cesium JS developer?

To thrive as a Cesium JS Developer, you need strong proficiency in JavaScript, web development, and 3D geospatial concepts, often supported by a related degree or experience in GIS. Familiarity with the CesiumJS library, WebGL, and mapping platforms, as well as knowledge of APIs and version control systems like Git, is typically required. Attention to detail, problem-solving skills, and the ability to communicate complex technical ideas clearly are valuable soft skills in this role. These competencies ensure the effective development and deployment of interactive 3D maps and geospatial applications that meet user and project needs.

What are some common challenges Cesium JS developers face when integrating 3D geospatial visualizations into web applications?

CesiumJS developers often encounter challenges such as optimizing performance for large datasets, ensuring cross-browser compatibility, and managing accurate real-time updates to geospatial data. Working with high-resolution terrain and imagery can be resource-intensive, requiring careful handling of memory and network usage. Additionally, developers frequently collaborate with GIS specialists and backend teams to process and deliver data efficiently, making clear communication and strong problem-solving skills essential in this role.

What is the difference between Cesium Js vs Web GIS Developer?

AspectCesium JsWeb GIS Developer
Required CredentialsJavaScript, 3D mapping, GIS conceptsJavaScript, GIS, spatial data handling
Work EnvironmentWeb applications, 3D visualizationWeb-based GIS platforms, spatial data analysis
Industry UsageGeospatial visualization, 3D mapping projectsGIS solutions, spatial data management

Cesium Js specialists focus on creating 3D geospatial visualizations using JavaScript, while Web GIS Developers work on broader GIS applications, including 2D maps and spatial data analysis. Both roles require JavaScript skills and GIS knowledge, but Cesium Js is more specialized in 3D visualization, making it ideal for projects needing immersive geospatial experiences.

Job description

Position Summary
We are seeking a Senior Software Engineer to be a primary technical contributor on the Multimode Threat Engagement Simulation Platform. You will own significant portions of the stack end-to-end - building the Julia computation backend, the React/TypeScript/CesiumJS frontend, and the CI/CD pipeline that delivers standalone Windows and Linux artifacts - with a primary emphasis on high-performance and scientific computing. You will work closely with the Lead Engineer on architecture decisions and with domain engineers (RF, EO/IR) to implement their physics models in a performant, maintainable form.
This role demands genuine depth in high-performance compute application development. The backend is not a conventional web API - it runs trajectory integration, Monte Carlo simulation across thousands of runs, and real-time surrogate model inference. You should be comfortable profiling and optimizing numerical code, reasoning about parallelism, and making informed trade-offs between simulation fidelity and throughput.
***Contingent upon contract award***
Responsibilities
High-Performance Computation Backend
  • Implement and optimize the Julia physics computation server: trajectory integration (RK4/RK45 schemes via DifferentialEquations.jl), SGP4 orbital propagation (SatelliteToolbox.jl), and Monte Carlo driver with Threads.@threads parallelism
  • Profile and optimize computation-critical paths; benchmark throughput and latency against program requirements (e.g., 10,000 Monte Carlo runs within a defined wall-clock target)
  • Integrate ONNX.jl surrogate model inference for real-time parameter sweep capabilities; ensure inference latency meets the <1ms interactive target
  • Implement CZML generation from physics outputs - trajectory arcs, satellite orbital paths, coverage footprints - for time-dynamic Cesium visualization
  • Design and maintain the mission data model: JSON serialization, versioned file format with backward compatibility, and cross-platform path handling for Windows and Linux
  • Implement the HTTP.jl API layer with well-defined request/response schemas, appropriate error handling, and structured logging

Frontend and Visualization
  • Build React/TypeScript components for the mission planning interface: tabbed mission overview, asset and task tree views, mission parameter forms, and the analysis panel
  • Integrate and maintain the CesiumJS/Resium 3D globe: asset markers, trajectory rendering, satellite ground tracks, coverage footprints, and CZML-driven animation with the Cesium timeline
  • Manage frontend application state (mission data, UI state, async physics query results) using appropriate state management patterns for a data-heavy desktop application
  • Implement data-driven analysis visualizations - trajectory plots, Pk curves, Monte Carlo distribution charts - using Recharts, Plotly.js, or equivalent

DevOps and Cross-Platform Packaging
  • Maintain the CI/CD pipeline in GitHub Actions: automated builds producing Windows NSIS installers and Linux AppImages from a single codebase
  • Manage PackageCompiler.jl sysimage builds for the Julia physics server binary on both target platforms
  • Maintain electron-builder configuration and platform-specific packaging scripts; validate installer behavior on clean Windows and Linux test environments
  • Implement build-time embedding of ONNX model files and asset resources; manage versioning of bundled artifacts

***Contingent upon contract award***
Qualifications
Citizenship: Must be a US citizen
Minimum Required Qualifications
Clearance: Active Secret Clearance
Education: B.S. in Computer Science, Software Engineering, Electrical Engineering, Physics, or related STEM field

Certifications: NA
Additional Skills
  • Proficiency in TypeScript/React or equivalent modern frontend framework
  • Experience with a compiled or JIT-compiled high-performance language (Julia, C++, Rust, Fortran, or Python with NumPy/Numba/Cython extensions)
  • Understanding of parallel computing patterns relevant to numerical workloads: thread-level parallelism, SIMD, memory-access optimization
  • Experience with REST API design and implementation as a client-server boundary within a single-machine application
