backend Developer

We are seeking a Senior backend Developer to lead the architecture and implementation of a GIS-oriented, distributed backend system. The system is currently in a Proof-of-Concept phase, with a clear trajectory toward a production-grade, mission-capable solution. This role is hands-on and design-heavy, focusing on building clean, extensible foundations for a microservices-based system that integrates Real-Time sensor data, geospatial processing, and a COTS GIS platform. You will define core architectural decisions that enable rapid iteration today while avoiding costly redesigns later. Key Responsibilities Architecture & Technical Leadership
* Design the backend architecture using modern.NET ( C #), ensuring scalability from POC to production.
* Define microservices boundaries, service contracts, and data ownership models.
* Lead the design of the inter-service communication layer, evaluating and selecting messaging/communication patterns based on latency, reliability, and deployment constraints. backend Development
* Implement core services for ingesting and processing sensor-driven data streams (e.g., radar inputs).
* Design APIs and internal messaging patterns supporting low-latency and near- Real-Time workflows.
* Build services that integrate spatial and non-spatial data using PostgreSQL and PostGIS.
* Ensure performance is sufficient for Real-Time visualization without over-engineering early-stage components. GIS & system Integration
* Integrate backend services with GIS map servers (e.g., Carmenta Map Server, LuciadFusion, Cesium ion).
* Collaborate with frontend developers using Angular, OpenLayers, and CesiumJS. Infrastructure & Deployment
* Define containerization and deployment workflows using Docker / Podman (Compose-based, no Kubernetes).
* Design for on-premise constraints, including limited scalability and intermittent network reliability.
* Introduce lightweight observability (logging, metrics), with a path to production-grade monitoring. Reliability & Security
* Design secure service communication and basic identity/access mechanisms.
