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

1. 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.

1. 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.

1.



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: Experience with Docker, Kubernetes, and Linux Server
- Databases: Familiarity with Time-Series DBs (InfluxDB, Timescale) and NoSQL (MongoDB/DynamoDB).

Preferred Qualifications:

- Experience: 5+ years of experience in the development of scalable server applications.
- Experience with Digital Twin concepts and modeling.
- Knowledge of distributed architecture design using Kafka & Redis
- Familiarity with DevOps for IoT (CI/CD pipelines for hardware-in-the-loop testing).

Pay: ₹18,000.00 - ₹22,000.00 per month

Benefits

- Cell phone reimbursement
- Adaptable schedule
- Leave encashment
