Embedded engineering roles can vary widely based on the focus, industry, and responsibilities involved. Key differences often arise from the specific domain, skill set, and project requirements. Here’s a breakdown:

Firmware Engineer vs. Hardware Engineer:
A firmware engineer works on software that interacts directly with the hardware, focusing on low-level coding, drivers, and real-time operating systems (RTOS). A hardware engineer designs, tests, and builds the physical components like circuit boards and processors. These roles require collaboration but involve distinct skill sets.

Application-Level vs. Low-Level Engineers:
Application-level embedded engineers develop software solutions at a higher level, such as user interfaces and APIs, while low-level engineers focus on device drivers, bootloaders, and hardware-software interfacing.

Domain-Specific Roles:
Embedded engineers may specialize in industries such as automotive, IoT, medical devices, or telecommunications. For instance, automotive engineers might work with CAN protocols, while IoT engineers deal with wireless communication standards like Bluetooth or Zigbee.

System Design vs. Testing Roles:
System design engineers architect solutions, choose components, and integrate systems. In contrast, testing engineers ensure the system's reliability and performance by developing test cases and debugging.

Full-Stack Embedded Developers:
These engineers handle both hardware and software aspects, making them versatile in smaller teams or startups.

Research vs. Product Development:
Research-oriented roles focus on innovation and prototyping, while product development engineers work on refining products for the market.
