Artificial Intelligence (AI) is revolutionizing industries and transforming the way we live and work. As more organizations incorporate AI into their operations, the demand for skilled AI engineers continues to grow. I’ve spent a considerable amount of time in the cloud industry and what’s happening right now reminds me a lot of what we saw in 2012-2013 when cloud computing became a popular topic in the enterprise and companies started adopting it.

Right after that, we started seeing cloud skills becoming popular and most software engineers had to learn AWS, Azure, DevOps, and a variety of other cloud skills that today are somehow considered the normality for someone who builds software or works in the IT space.

I think Artificial Intelligence and the birth of solutions like OpenAI, Anthropic, and others will somehow create a similar revolution for the world of software engineers and developers.

It will definitely be different: cloud was a unique revolution in many ways and it took a few years to really become something that enterprise companies would be forced to adopt, I think AI will change the role of software developers (and how companies build software) much faster. We are already seeing the effects of that today, our developers at Anthropos use copilot to write code faster and save time every day (one of our devs said that is currently saving about 2 hours a day just using Microsoft Copilot).

While using an LLM (Large Language Model) through APIs might sound like a simple approach, we will see now more and more developers learning new advances skills on machine learning and AI to also personalize some of the existing solutions. Some companies are already training their own models and I expect this to become a trend as more companies adopt AI inteo their software.

There are new skills that developers need to acquire and get used to and not all of them are just technical skills, some of them are simply a new way of working as a developer with the support of AI to write your software.

But what exactly are the essential skills that make an AI engineer successful in this fast-paced and constantly evolving field?

Understanding the Role of an AI Engineer

An AI engineer is responsible for developing and implementing AI-based solutions to solve complex problems and we said, we are focusing here on those ones that are going to be slightly more advanced than just implementing a modern LLM.

They work closely with data scientists, software engineers, and domain experts to design, build, and deploy AI models and systems. Their expertise lies in leveraging machine learning algorithms and deep learning techniques to train models that can make informed decisions and predictions based on vast amounts of data. AI engineers play a crucial role in the development and advancement of artificial intelligence.

They are the architects behind the intelligent systems that help the rest of the organization – and most times of the software team – to tune and customize models for specific use cases or for specific industries. At Anthropos, for instance, we spent quite a bit of time tuning our Skills Taxonomy, built using AI, and we definitely needed to get into the realm of AI engineers.

With their deep understanding of machine learning algorithms and data analysis techniques, AI engineers are able to create models that can learn from data and make accurate predictions. Let me suggest this recent video that talks about the rise of the AI engineer as a new profession and dives deep into what that means.

Key Responsibilities of an AI Engineer

One of the primary responsibilities of an AI engineer is to understand and define the problem at hand. They need to analyze the available data and identify the appropriate machine-learning algorithms that can be used to address the specific requirements. This requires a deep understanding of the problem domain and the ability to translate it into a machine learning problem.

Compared to the past, several engineers today will rather adopt an LLM to be integrated – with APIs – in their code, instead of working with an external library for machine learning.

Once the problem is defined, AI engineers work on data preprocessing. This involves gathering, cleaning, and transforming the data to make it suitable for training AI models. They need to ensure that the data is accurate, complete, and representative of the problem at hand. This step is crucial as the quality of the data directly impacts the performance of the AI models.

After data preprocessing, AI engineers proceed with model training. They use machine learning algorithms and deep learning techniques to train models on the prepared data. This involves feeding the data into the models and adjusting the model parameters to optimize performance. AI engineers need to constantly evaluate the performance of the models and make improvements as needed.

Another important responsibility of AI engineers is model deployment. They need to ensure that the trained models can be integrated into existing systems and can make real-time predictions.

This requires expertise in software engineering and the ability to work with different programming languages and frameworks.

While writing this article I’ve found the recording of the AI Engineer Summit 2023 and the content is great if you want to learn more about the tools and skills you should consider in your path to become an AI engineer. I am posting below the first session video, but you can easily find the second one always on YouTube:
