We’re looking for engineers who can work across the full stack: React frontend, Python serverless backend, AWS cloud infrastructure, and IoT data pipelines. You’ll build and maintain our unified IoT device management and monitoring platform that powers the complete lifecycle of smart building deployments: field site surveys, device installation, provisioning, real-time monitoring, data verification, and analytics dashboards.
What You’ll Do
• Build and enhance features across a React frontend with modular, permission-based architecture
• Develop Python serverless backends with REST APIs, DynamoDB, and time-series data integrations
• Design and deploy AWS cloud infrastructure using Infrastructure as Code
• Work with IoT data pipelines: LoRaWAN sensors, gateways, decoder functions, and telemetry data storage
• Build data verification and quality assurance systems ensuring sensor data integrity across hundreds of devices
• Create dashboards and analytics for water, energy, and environmental monitoring
• Implement device provisioning and field installation workflows
• Maintain multi-tenant architecture with role-based access control and enterprise-grade security
What We’re Looking For
Required
• 5+ years with React (hooks, context, routing) and modern JavaScript/ES6+
• 5+ years with Python and serverless backend development
• Hands-on experience with AWS cloud services: compute, API management, DynamoDB, storage, and authentication
• Experience with Infrastructure as Code (CDK, CloudFormation, or Terraform)
• Familiarity with REST API design and authentication patterns (JWT, IAM-based signing)
• Comfort working across the full stack: frontend, backend, and cloud infrastructure
• Strong debugging skills: tracing issues end-to-end from UI through APIs to backend logs
Nice to Have
Experience with IoT protocols (LoRaWAN, MQTT) or IoT cloud services
Experience with time-series databases
Experience with BI/analytics tools (QuickSight or similar)
Familiarity with serverless and event-driven architectures
Experience with DynamoDB data modeling (partition keys, GSIs, query optimization)
Background in sustainability, smart buildings, or facilities management
