IoT Platform & DevOps Engineer – ThingsBoard (Docker) & Linux Edge (BLE)

About the Project: We are launching an Alpha 1 working model validation for a Remote Patient Monitoring (RPM) clinical pilot. To ensure rapid deployment, we are completely bypassing custom hardware/PCB design for this initial phase and utilizing off-the-shelf, retail-enclosed Linux edge gateways (Orange Pi / Raspberry Pi) running stock Ubuntu Server. We need a skilled independent IoT developer or micro-consultancy to take complete ownership of the local data aggregation script and the cloud-agnostic platform infrastructure. Scope of Work: Edge-Side Data Collection (Python/Linux): Configure local data collection pipelines on our Ubuntu-based edge gateway to handle and maintain concurrent Bluetooth Low Energy (BLE) connections from 6 distinct medical sensors at a patient's bedside. Cloud Infrastructure Deployment: Set up and optimize a containerized, cloud-agnostic ThingsBoard Community Edition backend via Docker Compose on our Hostinger VPS server. Multi-Tenant Architecture: Configure secure, clean, isolated B2B multi-tenant rule chains and Entity Views within ThingsBoard so separate hospital facilities can securely access their own automated streaming dashboards. Data Routing: Ensure reliable data transmission of formatted JSON strings over MQTT from the edge to ThingsBoard with basic error handling/retry mechanisms. Required Technical Skills: Hands-on experience architecting ThingsBoard Community Edition (Multi-tenancy, Rule Chains, Entity Views, Data Converters). Proficiency with Docker and Docker Compose on cloud servers (Hostinger VPS). Strong scripting skills in Python for hardware/protocol orchestration. Deep understanding of Linux networking stacks, MQTT brokers (Mosquitto), and BLE GATT profiles. Experience with single-board computers (Raspberry Pi, Orange Pi) operating as edge gateways.
