What is an AI Engineer?

by Stephen M. Walker II, Co-Founder / CEO

What is an AI Engineer?

An AI Engineer is a professional who specializes in creating, programming, and training the complex networks of algorithms that constitute artificial intelligence (AI). They apply a combination of data science, software development, and algorithm engineering to ensure that computers can perform tasks that typically require human intelligence, such as recognizing speech, making decisions, and predicting outcomes.

What are AI Engineers responsible for?

AI Engineers are responsible for:

  • Developing AI models using machine learning algorithms and deep learning neural networks.
  • Writing code essential for machine functioning and building data science infrastructure.
  • Analyzing statistics, data, and algorithms to make strategic recommendations aligned with company goals.
  • Ensuring seamless AI development and integration in collaboration with machine learning and data engineers.
  • Staying current on AI knowledge, trends, and regulations.
  • Communicating complex AI concepts to non-technical stakeholders.
  • Building and maintaining AI systems and products.

How can I become an AI engineer?

To become an AI Engineer, one typically needs:

  • A bachelor's degree in computer science, data science, mathematics, or a related discipline.
  • Expertise in programming languages such as Python, R, Java, Scala, TypeScript, and C++.
  • Knowledge of probability, statistics, calculus, and other mathematical disciplines.
  • Continuous learning and adaptability to keep up with the rapidly evolving field.
  • Critical thinking and problem-solving skills.

The demand for AI Engineers is growing, with job growth projected to be around 21% between 2021 and 2031, which is much faster than many other fields. AI Engineers are sought after in various industries, including finance, healthcare, transportation, and entertainment, due to their ability to leverage data to guide companies toward more efficient and innovative practices. The average annual salary for an AI Engineer in the U.S. was reported to be $247,769 as of July 2023.

AI Engineer vs Data Scientist

AI engineers and data scientists play distinct yet complementary roles in AI and ML fields. AI engineers are tasked with the creation and implementation of AI systems capable of tasks like image recognition and natural language processing. Their work involves algorithm development, model selection, and system optimization, requiring proficiency in programming languages such as Python or Java, and a solid foundation in mathematics, including calculus, linear algebra, and probability.

Conversely, data scientists focus on extracting insights from large datasets to inform data-driven decisions. They employ statistical methods, machine learning algorithms, and visualization tools to process and interpret data. Their skill set includes strong analytical abilities, programming expertise, particularly in R or Python, and familiarity with database systems and visualization software like Tableau or Power BI.

AI Engineers VS Software Engineers

AI engineers specialize in the development of intelligent systems capable of tasks like image recognition and natural language processing. They design algorithms, select machine learning models, and optimize system performance, requiring a strong foundation in both programming languages, such as Python or Java, and mathematical concepts including calculus, linear algebra, and probability theory.

In contrast, software engineers focus on creating software applications tailored to business needs. They engage with stakeholders to gather requirements, architect solutions, code, and test systems to meet performance and quality standards. Their expertise spans programming languages like C++ or Java and software development methodologies like Agile or Waterfall.

AI Engineers vs Machine Learning Engineers

AI engineers and machine learning (ML) engineers both play pivotal roles in the AI field, yet their responsibilities and expertise diverge. AI engineers are tasked with the end-to-end creation and deployment of AI systems capable of complex functions like image recognition and natural language processing. Their work encompasses algorithm development, machine learning model selection, and system optimization. They must be adept in programming languages such as Python or Java and possess a deep understanding of mathematical concepts including calculus, linear algebra, and probability theory.

On the other hand, machine learning engineers focus on the design, construction, and maintenance of ML models that learn from data to predict outcomes or make decisions. Collaborating with data scientists, they refine the problem scope, engineer features, and adjust model parameters for peak performance. Their technical proficiency in programming languages, particularly Python or R, is complemented by their knowledge of various ML algorithms, including but not limited to decision trees, neural networks, and support vector machines.

What is the computational complexity of common AI algorithms?

The computational complexity of common AI algorithms varies depending on the specific algorithm. For instance, the computational complexity of a simple linear regression algorithm is O(n), where n is the number of features. Conversely, the computational complexity of more complex algorithms like deep learning neural networks is significantly higher and can reach O(n^2) or even O(n^3) in some cases, where n is the number of nodes in the network. It's important to note that a higher computational complexity often means the algorithm requires more resources and time to train and run, which can impact the efficiency and effectiveness of the AI model.
