Job Description

IoT System Development & Integration

•  Design and develop scalable, secure IoT systems for device monitoring, control, and data exchange.
•  Integrate microcontrollers (Raspberry Pi, Arduino, ESP32, etc.) with various sensors and actuators.
•  Use protocols such as MQTT, HTTP REST, AMQP, and WebSockets for device-to-cloud and device-to-device communication.

Software Development

•  Develop modular applications using Python, JavaScript, Node.js, Java, and Node-RED.
•  Implement Linux-based services and IPC mechanisms to manage sensor data and edge logic.
•  Build fault-tolerant, maintainable code for long-term remote operation.

Monitoring, Database Management & Reporting

•  Design and implement real-time monitoring systems to track device uptime, sensor health,

communication status, and process anomalies.

•  Develop custom dashboards and alerting mechanisms using tools like Grafana, InfluxDB, Prometheus, or

Elastic Stack.

•  Integrate monitoring with cloud-native tools such as AWS CloudWatch, Azure Monitor, or Google

Operations Suite.

•  Manage time-series and relational databases for high-volume IoT data, ensuring proper indexing,

backups, and performance tuning.

•  Build and automate the generation of periodic reports (e.g., daily, weekly, monthly) for device

performance, energy usage, system health, etc.

✓ Reports can be exported in formats like PDF, Excel, or via scheduled email delivery.

•  Implement data aggregation, anomaly detection, and auto-summary logic for efficient insights.

Cloud & Analytics Integration

•  Integrate with public cloud platforms (AWS, Azure, Google Cloud) to support data storage, analytics,

device provisioning, and remote command execution.

•  Leverage cloud functions and rule engines for processing and reacting to telemetry data.

Web & Mobile Application Support

•  Develop and expose RESTful APIs for dashboards, mobile apps, or third-party system integrations.
•  Collaborate with frontend teams to deliver user-friendly monitoring and control interfaces.
•  Use React.js to build local and web-based dashboards, ensuring responsive design, real-time updates, andsmooth user interactions.

Networking & Security

•  Configure and manage IPv4 network settings on edge devices, gateways, and industrial controllers,

including static IP assignment, DHCP, and subnet masking.

•  Understand IP addressing, subnetting, default gateways, routing, and NAT (Network Address Translation)

in industrial and enterprise network environments.

•  Setup point-to-point and multi-device network topologies using routers, switches, and firewalls to

connect IoT devices across different VLANs or subnets.

•  Ensure reliable LAN/WAN/WLAN connectivity across on-prem and remote deployments, optimizing

latency and availability.

•  Implement network troubleshooting using tools like ping, traceroute, netstat, nmap, and protocol

analysers such as Wireshark.

•  Apply network segmentation for security and performance isolation of device clusters.
•  Enable secure communication using TLS/SSL, token-based authentication (e.g., JWT), and certificate

management (X.509) for MQTT/HTTPS.

•  Monitor and log network behaviour to detect abnormal activity, packet loss, or security breaches.

Operational Deployment & Support

•  Support system deployment at customer sites or production environments.
•  Perform diagnostics, root cause analysis, and firmware updates remotely or on-site.
•  Maintain detailed documentation for system architecture, deployment, and troubleshooting.
•  Ability to design end to end solution for IoT deployment based on customer’s requirements.

Tech Stack Knowledge

•  Solid understanding of the IoT technology stack, from edge devices to cloud platforms.
•  Hands-on experience with:

✓ Programming Languages: Python, JavaScript (Node.js), Java, Bash

✓ Frontend: React.js, HTML, CSS, WebSocket for real-time UI

✓ Platforms & Tools: Node-RED, Docker, Git, Linux (Ubuntu, Debian)

✓ Databases: PostgreSQL, MySQL, InfluxDB, MongoDB

✓ Cloud Services: AWS IoT Core, Azure IoT Hub, Google IoT, Firebase

✓ Messaging Protocols: MQTT, HTTP/REST, AMQP, WebSocket

✓ Networking Tools: Wireshark, iptables, ifconfig/ip, nmap

•  Familiarity with DevOps tools and workflows for CI/CD, automated testing, and remote deployments.
•  Working knowledge of cybersecurity best practices for IoT devices, including encryption, access control,and firmware integrity.

Job Requirements

Bachelor’s degree in Computer Science, Mechatronics, or a related field.

•  Min 3 years of experience in IoT, embedded development, or full-stack integration.
•  Solid programming skills in Python, JavaScript (Node.js), or Java.
•  Understanding of embedded systems, microcontroller I/O, and real-time data acquisition.
•  Familiarity with Linux, shell scripting, and system administration.

Preferred Skills

•  Experience with industrial protocols: Modbus, IO-Link, CAN, OPC UA, Profinet.
•  Integration with industrial controllers such as Siemens PLCs (e.g., S7-1200/1500), and communication over Modbus TCP/RTU, OPC UA, or Profinet, is considered an added advantage.
•  Knowledge of SQL/NoSQL databases (e.g., PostgreSQL, MySQL, InfluxDB, MongoDB).
•  Experience with Docker, CI/CD, and containerized IoT deployments.
•  Familiarity with reporting tools or automated scripts for generating reports.
•  Frontend development using React.js, especially for real-time, device-linked dashboards.
