need a senior-level architect to design the complete device-to-cloud platform.
This is not a front-end job.
This is not a simple firmware job.
We need someone who can design a scalable IoT infrastructure that can grow from 500 → 5,000 → 50,000 devices
You will design the architecture for:
• Device identity & secure provisioning
• Device authentication (certificates / PKI / mutual TLS)
• OTA update strategy
• Secure device-to-cloud communication (MQTT or HTTPS)
• Edge data abstraction (feature extraction before upload)
• Cloud ingestion pipeline
• Time-series database schema
• Multi-tenant architecture (facility-level isolation)
• Real-time event engine (alert layer)
• API layer for future platform expansion
Deliverables:
• Full architecture diagram
• Data schema design
• Security design document
• Scalability roadmap
• Recommended cloud stack (AWS preferred, but open to Azure/GCP)
Required Experience
• Designed IoT platforms with 1,000+ deployed devices
• Experience with AWS IoT Core (or similar)
• Strong understanding of MQTT / secure transport
• Time-series database design (DynamoDB, InfluxDB, PostgreSQL, etc.)
• Multi-tenant SaaS architecture
• OTA design experience
• Security-first mindset (secure boot, device certs, encrypted transport)
Bonus:
• Experience in healthcare or regulated environments
• Experience building scalable API layers
• Real-time data processing (Kafka, Kinesis, etc.)
