ML Engineer Skills: Defining Core Skills for First Hires
ML engineering skills are projected to be core roles for businesses for the next 5 years at least. It is currently one of the most sought-after AI skills on US job postings. Today, ML engineering skills can be the key to building a competitive edge – like attracting more customers to your business or building loyalty. But before building an ML team for your organisation, it’s important to understand what they do, and how they add value and that starts with understanding what ML Engineer skills are.
What Does an ML Engineer Do in a Tech Team?
As a subcategory of AI, machine learning is about training computer systems with a set of instructions to eventually understand patterns and perform tasks without explicit instructions. Machine learning engineers train systems to do just that.
Their primary responsibility involves taking models from idea and development to production. These professionals make sure your AI solutions work at scale, not just on paper.
Here are examples of ML engineer responsibilities:
- Designing and implementing machine learning systems that can handle real-world data volumes
- Building MLOps infrastructure for experimentation, deployment, and monitoring
- Creating pipelines for continuous training and automated validation
- Optimising models for performance and scalability
ML engineers collaborate closely with data scientists through an iterative process. Data scientists develop candidate models, while ML Engineers optimise these models and build the infrastructure needed to deploy them.
ML engineers systematise your AI/ML practices, establishing best practices that enable consistent results across your organisation. ML engineer skills become a strong business pillar when you want to grow AI applications beyond initial experiments.
Top Technical ML Engineer Skills to Prioritise for First Hires
1. Strong Statistics Skills
A mathematical background is considered one of the strongest ML engineer skills to look for when deciding to build your first ML team. Your team will develop your AI model, which runs on math and coding. Maths is the foundation.
Mathematics and statistics knowledge provide the conceptual foundation for understanding machine learning algorithms. Engineers need probability theory to quantify uncertainties, while statistical knowledge helps them estimate parameters and extract meaningful conclusions from data.
Hire talent with strong algebra, statistics, and probability skills. Find candidates who know how to use these skills to solve your customers’ real problems. Doing so pulls your AI project away from being a part of those 80% that never make it to go live.
2. High Literacy in Programming Skills
This is another specific technical foundation that will support your AI initiatives from day one. Literacy in programming languages is one of the core ML engineer skills in the AI game. The most popular ones include Python, Java, C++, and MATLAB. So make sure your team has access to the latest tools to maximise their expertise and accelerate skills improvement as they work on your AI model.
3. Proficient in software engineering Skills
Software engineering skills matter just as much as algorithm knowledge when listing your new hires’ core ML engineer skills. They must be experienced and ready to write robust, efficient, and maintainable code.
Why? Mastering best practices like modular development and version control will dictate a model’s success when transitioning from experimental notebooks to production environments.
Some new hires have limited experience in software engineering skills. They are often new graduates or candidates just starting in tech. But even with limited experience, entry-level engineers offer skills that tenured talents often lose.
To maximise the beginner market for your AI project, make sure to add inclusive terms in the job description. Some soft skills that show a candidate is highly teachable are adaptability, active listening, and being receptive to feedback. Requiring software engineer training certificates can also help verify that candidates are actively practicing these soft skills.
4. Dependable Data Management
Data handling is also important when listing your ML engineer skills. The ability to transform raw data into analysis-ready formats while creating new features will offer a major boost in your AI model’s predictive power.
Version control expertise for both code and models should also be prioritised. This is one of the key ML engineer skills that ensures the team can maintain the quality and organisation of their models. This allows team collaboration throughout the machine learning lifecycle. The skill also becomes increasingly valuable as your team grows and AI projects grow in complexity.
Soft Skills and Practical Experience for Your ML Engineer Skills List
Technical skills only tell half the story when hiring your first ML engineers. This is where soft skills enter.
Here are some soft ML engineering skills to include:
- Communication skills. It helps ML engineers to build smooth team relationships and explain complex technical concepts to stakeholders who need actionable insights.
- Team collaboration. Relational awareness helps candidates collaborate with data scientists, developers, and even product managers for a successful model implementation.
- Time management. Hiring early ML engineers means there are lots of work to start and complete, so candidates who can smartly manage time can maintain a smooth personal and cross-team workflow.
Building Your First ML Engineering Team
Securing success when hiring your first ML team relies on research, research, and research. Maximise your network. Reach out to experts specialising in ML engineer talent for tech or AI projects, like hiring managers and recruitment agencies.
