Job Description

We are seeking a Senior IoT Platform Architect / Backend Engineer to design and scale a real-time IoT telemetry and control platform for millions of connected solar inverters and edge devices. The ideal candidate will architect and optimize a high-throughput, secure, and resilient data pipeline -- from MQTT ingestion to time-series storage and analytics.
You'll lead design and implementation of the end-to-end architecture, including:
MQTT Broker (EMQX/VerneMQ) clusters for device connectivity and secure telemetry ingestion.
Kafka-based streaming pipeline for durable, partitioned message processing at 100k-200k msg/sec scale.
Python (FastAPI/Django) consumers for validation, enrichment, and storage into TimescaleDB (Postgres) with Redis for low-latency caching.
Django REST Framework APIs and WebSocket gateways for real-time dashboards and control command flows.
Kubernetes-based deployment with auto scaling, Helm, and observability stack (Prometheus, Grafana, ELK/Opensearch).
Security-first design using mTLS, OAuth2/OIDC (Keycloak), and Cloud KMS/HSM for secrets.
You'll be responsible for capacity planning, data modeling, performance optimization, and ensuring high availability for millions of devices at sub-second latency. Experience with large-scale messaging systems, distributed databases, and time-series optimization is essential.
