Senior Embedded system Engineer - 6-8 Years Experience - Ahmedabad

The primary responsibility of this role is to build a robust embedded Gateway application that:

• Communicates with other embedded applications via APIs
• Periodically fetches, processes, and transforms data
• Integrates with external/cloud APIs
• Store/read data from storage/memory card
• Provides a lightweight on-device UI for configuration and monitoring

The role requires deep expertise in resource-constrained systems, network protocols, secure communication, and embedded UI patterns.

• JSON / XML
• Knowledge of:
• TCP/IP networking fundamentals
• API security and authentication

Embedded UI

• Experience building lightweight web-based UIs for embedded devices
• Familiarity with:
• HTML
• CSS
• Plain JavaScript (no heavy frameworks)

Nice-to-Have Skills

• Experience with:
• IP cameras, gateways, or IoT devices
• ONVIF, MQTT, or device-specific SDKs
• Knowledge of:

• Secure device provisioning and OTA updates

Key Responsibilities

1. Embedded Application & Gateway Development

• Design and develop embedded applications using C / C++ for:
• IP cameras
• Edge devices
• Other embedded Linux–based systems
• Implement a gateway application that:
• Fetches data from other embedded applications via REST, IPC, or SDK-based APIs
• Aggregates, filters, and processes incoming data
• Forwards processed data to external systems or cloud APIs
• Ensure reliable execution in resource-constrained environments (CPU, memory, storage).

2. Embedded Linux & System Programming

• Work extensively with Embedded Linux (ARM-based and similar architectures).
• Manage:
• Multithreading and synchronization
• Memory usage and performance optimization
• Process lifecycle and daemon services
• Implement periodic and event-driven task execution (timers, schedulers, cron-like mechanisms).

3. API Integration & Protocol Handling

• Consume and expose APIs on embedded devices:
• REST / HTTP / HTTPS
• JSON / XML payloads
• Integrate with:
• Device-side APIs (other embedded apps)
• External / cloud APIs
• Handle retries, error states, timeouts, and network failures gracefully.

4. Embedded UI Development (Configuration UI)

• Design and implement lightweight embedded UI for gateway configuration and monitoring.
• UI capabilities include:
• Menu/pages
• Textboxes
• Dropdowns
• Checkboxes
• Buttons
• Use HTML, CSS, and minimal JavaScript served from the embedded device.
• Enable configuration storage and runtime application without requiring device restarts.

5. Networking & Communication

• Implement secure and reliable communication using:
• TCP/IP
• HTTP / HTTPS
• WebSockets (if required)
• MQTT (optional / preferred)
• Design periodic polling mechanisms and event-driven communication models.
• Optimize network usage for low-bandwidth or unstable connections.

6. Security & Configuration Management

• Implement secure communication using TLS / SSL.
• Handle certificates, authentication tokens, and credentials securely.
• Design configuration persistence mechanisms (files, secure storage, SDK config stores).
• Implement audit logs and diagnostic logging for embedded systems.

7. Testing, Debugging & Documentation

• Debug embedded applications using logs, remote debugging, and profiling tools.
• Write unit tests and integration tests where applicable.
• Create technical documentation covering:
• Architecture
• API contracts
• Configuration flows
• Deployment steps
