Developer

Role Overview:
We are seeking a versatile IoT System Engineer &
Developer to design, build, and maintain the end-to-end infrastructure of our connected solutions.
You will be responsible for developing the "glue" that connects physical hardware to the cloud, ensuring low-latency communication, robust device management, and secure data transmission.
This role is 50% system architecture and 50% hands-on full-stack development.

Key Responsibilities
End-to-End System Design: Edge-to-Cloud Architecture: Design the communication pathways between sensors, edge gateways, and cloud platforms (AWS IoT Core, Azure IoT Hub, or private MQTT brokers).
Protocol Implementation: Develop and optimize data transmission using MQTT, CoAP, HTTP/2, and gRPC while considering bandwidth constraints and power consumption.
Firmware Integration: Collaborate with hardware teams to integrate embedded logic with high-level software services.
Software Development: Service Layer: Build scalable microservices (using Node.js, C#.Net, or Python) to ingest, process, and route high-velocity telemetry data.
API Development: Design and maintain RESTful and GraphQL APIs for front-end applications and third-party integrations.
Edge Logic:



Write scripts for edge devices to perform local data filtering, anomaly detection, and "store-and-forward" logic during connectivity outages.
Network &
Security: Connectivity Management: Knowledge of different IOT connectivity mediums like Wi-Fi, BLE, LoRaWAN, and Cellular (5G/NB-IoT).
Security First: Deploy end-to-end encryption (TLS/SSL), X.509 certificate management, and secure boot processes to protect the device fleet from vulnerabilities.
OTA Updates: Build and manage Over-the-Air (OTA) update pipelines to ensure fleet-wide security patches and feature releases.

Technical Skills &
Qualifications:
Languages: C#, C/C++, and JavaScript/TypeScript.
IoT Protocols: Deep knowledge of MQTT, AMQP, JSON Cloud/Infrastructure:
