Job Title: Full Stack Web Developer (Geospatial/3D Visualization Focus)

Location: Hybrid / On Site (EHT, NJ or Washington, DC)

Employment Type: Full-time (W-2) or 1099 Contractor (flexible based on candidate preference and project needs) Experience Level: Mid-level to Senior (3-8+ years preferred)

About the Role

We are seeking a talented Full Stack Web Developer to design, build, and maintain scalable web applications from user interface to database and deployment. You will be responsible for features end-to-end, with a focus on interactive, data-driven experiences -particularly those involving 3D geospatial visualization, mapping, or terrain rendering. Collaborate with product, design, and other engineers to deliver high-quality, responsive applications that drive business value.

In 2026, strong full-stack developers combine solid fundamentals with modern tooling (TypeScript, component-based UIs, cloud deployment) and awareness of specialized libraries like CesiumJS for 3D earth/globe visualizations.

Key Responsibilities

• Design and develop responsive, accessible front-end interfaces using modern JavaScript frameworks

• Build and maintain back-end services, APIs, authentication, and business logic

• Create, optimize, and query databases (SQL and/or NoSQL)

• Integrate front-end with back-end services and third-party APIs (including geospatial data sources)

• Write clean, maintainable, testable code following best practices

• Perform debugging, performance optimization, and cross-browser/device testing

• Participate in code reviews, architectural decisions, and agile processes (sprints, stand-ups)

• Deploy and monitor applications (CI/CD, cloud platforms, basic DevOps tasks)

• Troubleshoot production issues and implement fixes

• Collaborate with UI/UX designers, product managers, and other developers

• Stay current with emerging technologies (especially in 3D/web geospatial tools) and suggest improvements

Required Skills & Qualifications

• 3-8+ years of professional experience in full-stack web development

• Strong proficiency in JavaScript/TypeScript (TypeScript is essentially mandatory in most professional stacks)

• Front-end expertise:

• HTML5, CSS3 (Tailwind CSS, CSS-in-JS, or modern styling solutions)

• React.js (most common), Next.js, Vue.js, or Angular

• Back-end expertise (one or more):

• Node.js + Express / NestJS

• Python (Django / FastAPI / Flask)

• Java / Spring Boot

• Go, Ruby on Rails, or .NET (less common but still relevant)

• API design & consumption: REST, GraphQL, WebSockets

• Databases: PostgreSQL/MySQL (SQL), MongoDB or similar (NoSQL)

• Version control: Git (GitHub/GitLab/Bitbucket workflows)

• Testing: Unit/integration/end-to-end (Jest, React Testing Library, Cypress, etc.)

• Deployment & tools: Docker basics, AWS/GCP/Azure (at least one), Vercel/Netlify, CI/CD pipelines

• Understanding of responsive design, accessibility (WCAG), SEO basics, and web performance

• Strong problem-solving skills and ability to learn quickly

Preferred Experience

• Experience with CesiumJS (including its APIs, 3D globe/terrain rendering, CZML/GeoJSON data handling, entity management, and integration with React/Resium-highly desirable for geospatial or visualization-heavy projects)

• Experience with Next.js (App Router) or similar full-stack React frameworks

• TypeScript in both front- and back-end codebases

• Authentication/authorization (JWT, OAuth, NextAuth/Auth.js, Clerk, Supabase Auth)

• State management (Redux Toolkit, Zustand, React Query / TanStack Query)

• Cloud services (serverless, S3, Lambda, RDS, etc.)

• Basic DevOps (Docker, Kubernetes awareness, Terraform basics)

• Familiarity with AI tooling (GitHub Copilot, Cursor, Claude, etc.) for productivity

• Experience building real-world apps: e-commerce, dashboards, SaaS products, auth + payments, or geospatial/mapping/3D visualization tools

• Mobile-responsive or progressive web app (PWA) experience

• Geospatial data knowledge (e.g., GeoJSON, 3DTiles, imagery integration)

Education

Bachelor's degree in Computer Science, Engineering, GIS/Geospatial, or related field (or equivalent practical experience)

What We Offer (Typical Range)

• Competitive compensation:

• W-2 full-time: $75,000-$135,000+ base (depending on location/experience/level) + benefits

• 1099 Contractor: $55-$85+/hour (depending on scope, expertise, and project duration; potential for long-term extensions)

• Health benefits, 401(k) matching, PTO (for W-2); flexible terms for 1099

• Remote-friendly options, professional development budget

• Opportunity to work on meaningful products with modern tech stack, including cutting-edge 3D geospatial applications
