Principal Frontend (Geospatial)/WebGL Engineer

REQUIRED EXPERIENCE / SKILLS

• Strong JavaScript (ES6+ / TypeScript): Deep understanding of core JavaScript concepts. You must be highly comfortable with the event loop, memory management, closures, asynchronous programming (Promises/Async-Await), and performance optimization at the language level.
• 3D Rendering & Performance: Build and optimize real-time map rendering pipelines using WebGL, GLSL shaders, or frameworks like Three.js, CesiumJS, or Mapbox GL.
• Geospatial Data Integration: Process complex spatial data sets, map projections, coordinate reference systems, and vector/raster tile streams.
• Deep expertise with at least one major frontend framework (React, Angular, Vue, or similar).
• Proven experience designing scalable, resilient frontend architectures and applying appropriate design patterns.
• Experience consuming and integrating REST API applying design patterns.
• Strong use of unit tests and modern build/CI tooling.
• Experience leading, mentoring, or setting the technical direction of a team of engineers.
• Fluency in English.
• Experience: Typically 10+ years of software development experience with a strong track record of delivering large, complex systems.
• Communication: Exceptional ability to explain complex technical concepts to non-technical stakeholders and business executives.

As a Principal Frontend / WebGL Engineer at Technosylva, you will play a crucial role in shaping the architecture, quality, and technical direction of the interactive, data-rich web applications we build for our clients. You will lead the frontend engineering effort - setting standards and mentoring other developers while staying hands-on with the code - and help design and deliver high-performance, visually rich experiences, including real-time 2D/3D geospatial visualizations powered by WebGL. As we continue to scale, we are looking for a technical leader who can help us build better solutions.

RESPONSIBILITIES

• Own the technical vision and architecture of our frontend platform. Define the technical roadmap, design large-scale systems, and align technical goals with business objectives.

• Set and enforce standards for clean, efficient, maintainable, and well-tested code across the frontend team.
• Lead and mentor other frontend developers, performing code reviews and fostering technical growth.
• Integrate frontend components with existing products, backend services, and REST APIs.
• Optimize rendering performance, memory usage, and load times for large and complex datasets.
• Troubleshoot and debug complex issues across browsers and devices; recommend and implement improvements.
• Create technical documentation for reference and reporting.
• Technical Leadership: Solve the hardest engineering problems, guide multi-team projects.
• Cross-Functional Collaboration: Partner with product managers, executives, and other technical leads to plan future software capabilities.
• Taking ownership of software-related complaints and working toward finding solutions.
• Analyzing data to spot potential weaknesses or problems with software.
• Overseeing initial software rollouts and updates to ensure smooth implementation.
• Participating in leadership meetings to contribute to corporate strategy.
• Lead the technical vision, architecture, and end-to-end delivery of complex software systems while aligning engineering efforts with business goals.
