What is a Machine Learning Engineer?
Machine learning is an exciting field that allows computers to learn and adapt without being explicitly programmed.
A machine learning engineer designs and builds machine learning models that learn from data and make predictions. They use algorithms and statistical models to analyze data, develop predictive models, and improve machine learning systems.
Machine learning engineers work at the intersection of computer science, statistics, and engineering. They are responsible for:
- Building machine learning infrastructure
- Designing models
- Training models
- Integrating maching learning solutions into software applications.
They work on a variety of projects, from image recognition to natural language processing, deep learning and artificial intelligence, supporting data science teams in getting models to production.
Machine learning engineers are in high demand, and the field is rapidly growing. This demand is expected to continue to grow as more companies adopt machine learning technologies to improve their business processes. The growth in demand is reflected in the salary with the average machine learning engineer salary being $155k in the US.
What skills are required to become a Machine Learning Engineer?
Machine learning engineers need a strong technical background in computer science, mathematics, and statistics. They should have expertise in the following areas:
Programming languages - Machine learning engineers should be proficient in at least one programming language, such as Python, R, or Java. A good resource to learn Python programming is the Kaggle Python tutorials. From here you can then learn machine learning through their other helpful materials.
Software development practices - A skill that sets machine learning engineers apart from data scientists is the use of software development practices. These practices ensure a model is robustly developed, and ready for production. In particular machine learning engineers should focus on learning version control, testing and debugging.
Statistics and Probability - Machine learning engineers should have a strong understanding of statistics and probability theory, the foundations of machine learning.
Data modelling and evaluation - Without good data, there are no good models. Machine learning engineers should be able to design and build data models to be used to make predictions or decisions. They should also be able to evaluate the performance of these models and optimize them for accuracy and speed.
Machine Learning Algorithms - A strong understanding of machine learning algorithms is paramount, such as neural networks, decision trees, and support vector machines. They should be able to select the appropriate algorithm for a given problem and tune its parameters for optimal performance.
In addition to technical skills, machine learning engineers should also possess the following non-technical skills:
Communication - Working on cross-functional teams means communication is vital. Machine learning engineers need to be able to communicate complex technical concepts to both technical and non-technical stakeholders. As well as explaining concepts communication is important for being able to work collaboratively with data scientists.
Critical thinking - Machine learning engineers should be able to think critically and creatively to solve complex problems. They should be able to identify and evaluate different solutions and choose the best one for a given problem
Business Acumen - Having a good understanding of business needs and how machine learning can be used to solve business problems will give you an edge. You should be able to identify opportunities where machine learning can add value and develop solutions that meet business requirements.
How to become a Machine Learning Engineer
Despite popular belief, machine learning engineering has much more to do with strong programming skills than machine learning skills. At MLOps Now we recommend that you first get a strong understanding of programming (preferably in Python) and then begin to learn machine learning.
You can approach this by either self-learning with online resources or you can use a bootcamp/online course. There are many bootcamps and online courses that offer training in machine learning and data science. These programs can provide a more practical, hands-on approach to learning machine learning, and can be a good option for those who do not want to pursue a full degree program.
The progression of your education should be:
Strong programming skills
Machine learning tools (e.g. Pandas, scikit-learn, Tensorflow)
Machine learning theory
We recommend tools before theory as this will give you a practical introduction into the theory you will need to learn.
In addition to education, work experience is also important for becoming a machine learning engineer. There are several ways to gain work experience in machine learning, including:
Internships - Many companies offer internships to students and recent graduates to gain practical experience in machine learning. Internships can provide opportunities to work on real-world projects and develop practical skills.
Entry-level Jobs - Entry-level jobs in data science and machine learning can provide valuable experience in the field. These jobs can include data analyst, data engineer, or junior machine learning engineer roles.
Freelance Work - Freelance work can provide opportunities to work on a variety of machine learning projects and gain experience working with different clients and industries.
Personal projects can be a great way to gain practical experience in machine learning. It also shows your ability to companies when you apply for jobs. There are several types of personal projects you can work on, including:
Kaggle Competitions - Kaggle is a platform that hosts machine learning competitions. Participating in Kaggle competitions can provide opportunities to work on real-world machine learning problems and compete with other data scientists.
Open-source Projects - Contributing to open-source machine learning projects can provide opportunities to work on real-world projects and collaborate with other machine learning engineers.
Personal Blog - Starting a personal blog can be a great way to showcase your work and build a portfolio of machine learning projects. A blog can also provide opportunities to share your knowledge and connect with other data scientists.
Career Opportunities for Machine Learning Engineers
Machine learning engineers can work in a variety of industries, including:
