About the Role

We are looking for a Full Stack Developer to support the continued development of InfraCloud, a SaaS platform for inspection and analysis of engineering structures. The platform processes and visualizes large-scale geospatial and inspection datasets.

You will work across the full application stackfrom frontend UI components to backend services and data persistencewithin a modern JavaScript based architecture.

A central focus of this role is the design and development of a Progressive Web App (PWA) to enable cross-platform usage on iOS, Android, and Windows tablets, particularly for field operations with challenging connectivity conditions.

Responsibilities

• Design, implement, and maintain scalable full stack features using:
  • Frontend: Angular
  • Backend: Node.js (TypeScript, RESTful APIs / microservices)
• Lead the development of a Progressive Web App (PWA) for cross-platform mobile and tablet environments (iOS, Android, Windows)
• Implement offline-first architecture patterns, including:
  • Service Workers (background sync, caching strategies)
  • Local data persistence (e.g., IndexedDB)
  • Resilient synchronization mechanisms for intermittent connectivity
  • Develop responsive, mobile-optimized UI/UX for field usage scenarios
• Develop and optimize APIs for handling large geospatial and inspection datasets
• Work with PostgreSQL (schema design, query optimization, indexing strategies)
• Integrate and manage object storage solutions (S3-compatible storage)
• Collaborate on system architecture decisions (modularity, scalability, performance)
• Ensure code quality through testing, code reviews, and static analysis
• Contribute to performance optimization (frontend rendering, backend throughput, data pipelines)
• Work closely with domain experts (e.g., geodesists, engineers) to translate requirements into technical solutions

Required Qualifications

• Strong experience with JavaScript and TypeScript across frontend and backend
  • Solid experience with Node.js and Angular
• Proven experience building Progressive Web Apps (PWA), including:
  • Service Worker lifecycle and caching strategies
  • Offline-first application design
  • Cross-platform mobile optimization (iOS/Android/browser constraints)
• Experience designing and consuming RESTful APIs
• Proficiency with PostgreSQL (complex queries, schema design, performance tuning)
• Experience with Git-based workflows (preferably GitLab)
• Familiarity with cloud storage systems (AWS S3 or compatible)
• Understanding of software architecture principles (security, separation of concerns, modularization, API design)

Nice to Have

• Experience with geospatial data, 3D data, or point cloud processing
• Knowledge of WebGL, 3D visualization frameworks, or mapping libraries
• Experience with microservices architecture or distributed systems
• Familiarity with Docker / containerization
• Exposure to CI/CD pipelines and DevOps practices
• Background in engineering, surveying, or environmental data systems
