Moulding the Embedded Systems Engineers of Tomorrow: Adapting to a Constantly Transforming Technological Terrain

Lance HarvieJune 26, 2023

In the early days of my career, embedded systems engineers were the quiet heroes, armed with logic analyzers and soldering irons, capable of building the heart of devices, from simple digital watches to complex spacecraft control systems. They mastered the art of squeezing performance from minimal resources, their genius manifest in every piece of technology humming silently, unseen, but indispensable. However, the focus of engineering has undergone a paradigm shift. Today, embedded systems engineers, in this age of interconnected devices, are the pioneers of a new epoch, one defined not by discrete circuits, but by firmware, software, complex silicon and cloud computing. As we evolve into this digital era, new skills emerge as paramount, including cybersecurity, artificial intelligence (AI), machine learning (ML), and cloud technologies.

In the past, engineers were expected to be proficient in their core engineering subjects, but today, the rulebook is being rewritten. Our focus must now shift to adapt to these emerging fields. If we fail to adapt, we risk being left behind, like fossils of a bygone era.

Firstly, let's delve into cybersecurity. As our world becomes increasingly connected, the threat landscape widens. Cyberspace is no longer a niche realm; it is the new frontier, the battlefield of the 21st century. Engineers now need to consider security as a foundational aspect of their design process. Whether developing a web application or designing a power grid, cybersecurity is no longer optional. Every engineer, regardless of their specialization, must have a basic understanding of how to secure their work from malicious actors. This understanding includes knowledge of encryption, secure coding practices, and data protection laws.

Similarly, as AI and ML technologies become increasingly integral to our lives, a familiarity with these fields is rapidly becoming a critical requirement for engineers. Our world is brimming with data, a rich tapestry of information. However, this data is merely noise without the right tools to interpret it. This is where AI and ML come into play. AI is our attempt to replicate human intelligence in machines, while ML is a specific subset of AI that involves teaching machines to learn from and make decisions based on data.

This means that engineers need to familiarize themselves with the principles of AI and ML, even if they don't specialize in these fields. They need to understand how to collect, store, and process data in a way that allows AI systems to analyze it effectively. They must be familiar with the ethical implications of AI and ML, considering issues such as algorithmic bias and the impact of automation on employment.

Finally, the rise of cloud technology has transformed the way we store and process data. With the power of the cloud, engineers can access vast computational resources on-demand, enabling them to tackle problems of a scale previously unimaginable. However, to harness this power, engineers need to learn about cloud architectures, understand how to design for the cloud, and be able to secure data in the cloud.

In this rapidly evolving landscape, continuous learning is key. Engineers need to adopt a mindset of lifelong learning, seeking out new skills and knowledge as the field evolves. This might seem daunting, but it is a natural part of the engineering profession. After all, engineers are problem solvers by nature, driven by curiosity and a desire to make the world a better place. This is just the latest challenge for us to overcome.

To stay relevant, engineers need to embrace these new skills. Cybersecurity, AI, ML, and cloud technologies are not just buzzwords; they represent the future of our profession. By integrating these skills into our work, we can ensure that we remain at the forefront of technological innovation, driving the evolution of our field rather than simply reacting to it.

It's evident that the role of the embedded systems engineer is evolving. We're no longer just constructors of hardware; we are now protectors of data integrity, strategic planners, and visionaries of invisible systems. We are sculpting the unseen underpinnings of the future, where microprocessors are increasingly woven into the fabric of our daily existence. As we progress into this future, it becomes vital that we arm ourselves with the knowledge and skills crucial for navigating this intricate landscape.

The learning curve may seem steep, but remember, each step we take towards understanding these new skills is a step towards ensuring our relevance in the exciting future of engineering. As we embrace these changes and adapt to the evolving landscape, we become better engineers, better problem solvers, and ultimately, better custodians of the technological world we are helping to create.

The engineering profession is not standing still; it is evolving, growing, and shifting. As engineers, we must do the same. After all, as the great engineer Henry Petroski once said, "Engineering is not merely knowing and being knowledgeable, like a walking encyclopedia; engineering is not merely analysis; engineering is not merely the possession of the capacity to get elegant solutions to non-existent engineering problems; engineering is practicing the art of the organized forcing of technological changeā€¦ Engineers operate at the interface of science and society." It's time for us to push that interface forward and embrace the future.
