Core Responsibilities
1. System Design and Development
Software Development: Understanding the architecture developed by system architects and developing the code to run on microcontrollers or microprocessors. You will most often be using IDEs like Eclipse, MPLAB and using languages like C/C++. This development could be on bare metal or on an OS.
Hardware Design: Creating schematics and designing printed circuit boards (PCBs) that meet specific requirements.
2. Prototyping and Testing
Prototyping: Building and testing prototypes to validate designs and functionalities. This will help in weeding out any bugs in this stage.
Testing: Testing of embedded systems has become a complex task for current day embedded systems. This may require significant code development for test cases and test environments. This may also require additional equipment to be connected to the system under test.
Debugging: Identifying and resolving system issues using tools like JTAG, gdb or kdb along with measurement tools like oscilloscopes.
3. Integration
Component Integration: Ensuring seamless integration of various hardware components (sensors, actuators, communication modules) within the system to ensure they work cohesively. .
Software Integration: Combining all software modules and ensuring they work together smoothly.
4. Optimization
Performance Optimization: Enhancing the system’s performance by optimizing code, reducing power consumption, and improving response times.
Resource Management: Efficiently managing system resources, such as memory and processing power, to meet application needs.
5. Documentation and Compliance
Documentation: Writing detailed documentation for designs, code, and testing processes.
Compliance: Ensuring designs comply with industry standards and regulatory requirements. Carrying out any compliance tests in collaboration with compliance labs.
6. Collaboration
Cross-Functional Teams: Working closely with other engineers, project managers, and stakeholders to ensure project success. In the current day world with teams being global, working with cultural sensitivity is required.
Client Interaction: Interacting with clients to understand requirements, provide periodic updates on the work, bring up any issues you foresee and provide technical support.
