How to Become an Embedded Systems Engineer

What Is Embedded System Engineering?

Embedded system engineering is a field of engineering that focuses on designing, developing, and maintaining computer systems integrated into larger devices.  It is different than general-purpose computers. Embedded systems are designed for specific tasks and operate with real-time constraints.

Devices like your smartphone, washing machine, car's anti-lock braking system, and even your smartwatch all run on embedded systems. It’s important to understand that these are not standalone computers, but specialized computing units embedded within larger mechanical or electrical systems. 

Following are the 3 main domains that Embedded systems engineering combines: 

• Hardware design: Understanding microcontrollers, processors, sensors, and circuit design 
• Software development: Writing efficient, low-level code that directly interfaces with hardware 
• System integration: Ensuring hardware and software work seamlessly together 

Another notable aspect is that embedded engineers often work with kilobytes of memory and limited processing power. This constraint requires you to be innovative and efficient 

What Does an Embedded Systems Engineer Do? 

The job of an embedded engineer is really complex and the detailed outline of the job varies depending on the company and the sector you decide to work in. However, it might look like the following:

Design and Development 

• Conceptualizing circuit boards and microcontrollers or processors 
• Writing firmware and hardware-related software in C, C++, or assembly language 
• Creating device driver programs that facilitate the interaction between hardware components and software 
• Writing applications for real-time operating systems (RTOS) 

Testing and Debugging 

• Fixing the issues in hardware-software by using tools such as oscilloscopes, logic analyzers, and debugging tools 
• Checking the performance of the whole system through tests to be able to confirm the real-time requirements are met 
• Also, power consumption, thermal management, and system reliability aspects are checked 

Integration and Optimization  

• Employing integration methods for sensors, actuators, and communication modules 
• Refining the code from the point of view of memory consumption and execution speed 
• Ensuring that the device is in line with the industry standards and safety regulations 

Documentation and Collaboration  

• Preparing technical documentation for system architecture and code 
• Interacting with the teams which are not functionally related such as engineering of mechanics, product management, and quality assurance 

The job requires intellect but it is very rewarding. In a sense, you're essentially giving life to the products.

Skills Required to Become an Embedded Engineer 

Each of two categories of engineers, i.e., embedded hardware engineers and embedded software engineers, need to possess technical skills along with personality traits to be able to reach their career goals. 

Technical Skills: 

• Programming Languages: In both C and C++, one has to be proficient. It is these programming languages that allow the hardware to be controlled directly, something which is the core of embedded development. Apart from that, a little knowledge of assembly language might be helpful especially in the sections of the code that are oriented towards performance.
• Microcontroller Architecture: The knowledge about the microcontrollers of the families like ARM Cortex, AVR, PIC, and the other ones, their instruction sets, memory architecture, and peripheral interfaces.
• Hardware Knowledge: Should be able to get the idea of digital as well as analog electronics, read the process diagrams, recognize communication protocols (I2C, SPI, UART, CAN) and know the basics of the circuit theory.
• Real-Time Operating Systems: A concept of RTOS, ideas of task scheduling, inter-process communication, and memory management.
• Debugging Skills: JTAG debuggers, in-circuit emulators should be utilized in a skilled manner, at the same time, one should be able to pinpoint the hardware and software faults.

Soft Skills:

• Problem-solving skill: Embedded systems may be the sources of problems that are not solvable by the usual methods and which require inventing new ones.
• Attention to detail: It could be just one wrongly set register value or one misplaced semicolon that is all what it takes for the whole system to fail.
• Patience and persistence: The process of debugging embedded systems is very long, thereby requiring one to be patient.
• Communication skills: By giving examples to other people in a non-technical manner, you help them understand the concepts better.

Educational Qualifications and Courses for Embedded Systems

The path to becoming an embedded systems engineer typically starts with formal education, though self-learning has become increasingly viable.

Academic Foundation:

A bachelor's degree in Electronics Engineering, Computer Science, or Electrical Engineering provides the foundational knowledge. Relevant coursework includes:

• Digital electronics and microprocessors
• Data structures and algorithms 
• Computer architecture and organization 
• Signal processing 
• Control systems 

Specialized Courses: 

Several embedded systems engineer courses are available both online and offline: 

• University Programs: Many universities offer specialized master's programs in embedded systems
• Professional Certifications: Companies like ARM, Texas Instruments, and Intel offer vendor-specific training
• Online Platforms: Coursera, edX, and Udemy provide courses ranging from beginner to advanced levels
• Bootcamps: Intensive training programs focusing on practical embedded development skills

Certifications:

While not mandatory, embedded systems certifications enhance credibility:

• Certified Embedded Systems Engineer (CESE)
• ARM Accredited Engineer (AAE)
• Real-Time and Embedded Systems Specialist Certificate
