You will also develop data verification and quality assurance systems to ensure sensor data integrity across a large number of devices, create dashboards and analytics for environmental monitoring (water, energy), and implement device provisioning and field installation workflows. Maintaining a multi-tenant architecture with role-based access control and enterprise-grade security is also a crucial part of this role.

• Proficiency across the full stack, encompassing frontend, backend, and cloud infrastructure.
• Strong debugging skills with the ability to trace issues end-to-end from the UI through APIs to backend logs.

Preferred Qualifications:

• Experience with IoT protocols (e.g., LoRaWAN, MQTT) or IoT cloud services.
