C++ improves code organisation, enhances reusability, and maintains code. As C++ is undeniably one of the most essential programming languages for embedded systems, employers must prioritise candidates who demonstrate expertise and programming skills to succeed in programmer jobs.

2. Embedded Systems Concepts

Understanding key embedded systems concepts is vital for programmers in the field as it forms the foundation for designing efficient and reliable systems. Proficiency in concepts such as real-time operating systems (RTOS), power management, and low-level hardware interaction enables developers to navigate the intricacies of resource-constrained environments effectively. 

Let’s explore deeper into the key embedded systems concepts and why employers should look for this knowledge in programmers:

• Real-Time Operating Systems (RTOS) - Knowledge of RTOS is one of the essential programming skills candidates must possess. RTOS streamlines task management, manages resource allocation, and provides a strategic approach to interrupt handling. RTOS also supports modular design and offers specialised development tools to ensure reliable system operation. Employers must seek professionals who are knowledgeable in this area to ensure project goals are met. 

• Power Management - Power management is vital for embedded systems programmers as it ensures efficient utilisation of power resources, extends device battery life and reduces energy consumption. Programmers can build systems that meet power constraints for various applications by implementing dynamic voltage and frequency scaling strategies. Employers must look for programmers who are knowledgeable on power management strategies to help produce efficient and high-quality embedded systems.

• Low-Level Hardware Interaction -  Programmers require sufficient knowledge of low-level hardware interaction to effectively interface with and control the hardware components of embedded systems. This expertise ensures seamless integration between software and hardware, allowing programmers to create reliable embedded solutions that meet specific application requirements, making it an extremely valuable programming skill.

3. Software Development Skills

According to recent research, the global developer population is expected to reach 28.7 million people by 2024, with an increase of 3.2 million from 2020. This figure highlights the rapid growth and demand for software developers and programming skills across various industries, including embedded systems. So, it is essential for employers to search for candidates who possess proficient software development skills and knowledge of fundamental concepts.

Here are some of the critical software development skills programmers must acquire:

• Version Control Systems (VCS) - Knowledge of VCS is essential for programmers to efficiently manage and track changes to their code base throughout the process. VCS, such as Git, allows programmers to monitor code revisions and refer to previous versions if necessary, leading to easier code maintenance. Candidates who possess this knowledge are extremely valuable to employers. 

• Debugging Techniques - Employers must look for programming skills, such as knowledge of debugging techniques, in potential candidates who are able to identify and resolve issues within their codebase. Understanding debugging tools and methodologies allows programmers to identify software defects, pinpoint the root cause, improve their software and code's stability, and maintain successful systems.

• Software Methodologies - When hiring for programmer jobs in embedded systems, employers must ensure they hire candidates who are knowledgeable of various software methodologies. Knowledge of methodologies such as Agile or Waterfall enables efficient planning, execution, testing, and maintenance, allowing programmers to deliver high-quality solutions.

4. Networking and Communication Protocols

Embedded systems programmers require networking and communication protocols knowledge to enable seamless interaction between embedded devices and external systems. Understanding protocols such as SPI, I2C, and UART is an essential programming skill for establishing reliable communication channels, exchanging data, and interacting with other devices or networks. This expertise is essential for developing IoT devices, networked sensors, or smart systems that require connectivity.

When hiring for programmer jobs in embedded systems, employers must search for candidates who are knowledgeable on networking and communication protocols, such as:

• SPI (Serial Peripheral Interface) - SPI is commonly used for communication between microcontrollers and peripheral devices in embedded systems, so programmers must be able to demonstrate programming skills within this interface. A deep understanding of SPI allows programmers to ensure reliable data transfer and interface efficiently with memory chips and displays. Employers must search for candidates who have expertise in SPI to ensure fast and reliable communication between components.
