Many students interested in artificial intelligence (AI) hear about roles like data scientist, machine learning engineer, or AI developer. However, one role that is becoming increasingly important in modern AI development is the MLOps Engineer. An MLOps Engineer helps organizations move machine learning models from the development stage into real-world use. Students interested in MLOps can begin by building foundations in programming and machine learning before progressing to deployment, automation and monitoring concepts. At United Ceres College, Machine Learning Operations is one of the six modules in the Advanced Diploma in Applied Artificial Intelligence program, alongside areas such as computer vision, conversational AI, deep learning, NLP and generative AI systems. 

Creating an AI model is only one part of building a successful AI solution. A model may perform well during testing, but businesses need systems that continue working when thousands or millions of users interact with them. This is where MLOps becomes important. For example, a company may develop an AI system that recommends products to customers. A data scientist may create the recommendation model, but an MLOps Engineer helps ensure that the model is properly deployed, receives updated data, maintains performance, and can handle increasing numbers of users. In simple terms: A data scientist creates and improves the model.  An MLOps Engineer helps the model work reliably in the real world.

What Is MLOps?

MLOps stands for Machine Learning Operations. It combines practices from the following:

• Machine learning
• Software engineering
• Data engineering
• DevOps (development and operations)
• Cloud computing

The goal of MLOps is to create a smooth process for developing, deploying, and maintaining machine learning systems. Traditional software applications usually follow a development process where developers write code, test it, deploy it, and update it when needed. Machine learning systems are more complex because they depend on the following:

• Data quality
• Model performance
• Changing user behaviour
• Continuous updates

An AI model that works well today may become less accurate in the future if the data changes. For example, a fraud detection system used by a bank may need regular updates because customer behaviors and fraud techniques continue to change. MLOps provides the tools and processes needed to manage these changes.

Why Is MLOps Important?

Many people think building an AI model is the final step in creating an AI solution. In reality, deployment and maintenance are often some of the most challenging parts. A machine learning model must work outside a testing environment. Businesses need to answer questions such as:

• How can the model be made available to users?
• How can performance be monitored?
• What happens if accuracy decreases?
• How can new versions be released safely?
• How can large amounts of data be managed?

Without proper operations, even a highly accurate AI model may fail when introduced into real-world situations. For example: A healthcare organization may develop an AI tool that helps analyze medical images. Before doctors can use it, the organization needs systems to ensure the following:

• The model is securely deployed
• Data is processed correctly
• Model performance is monitored against appropriate validation criteria 
• Updates can be introduced safely

MLOps professionals may support these processes alongside data science, software, security, clinical, and governance teams. 

MLOps Engineer vs Data Scientist vs Machine Learning Engineer

Many AI-related roles overlap, which can make career choices confusing. Understanding the differences can help students decide which area matches their interests.

While these roles often work together, their responsibilities often differ, although the boundaries vary between organizations. A simple example: Imagine an online shopping platform wants to predict what products customers may like.

Data Scientist:

• Studies customer behaviour
• Creates recommendation models
• Tests different approaches

Machine Learning Engineer:

• Builds the software that uses the model
• Connects the AI system with the application

MLOps Engineer:

• Deploys the model
• Monitors performance
• Automates updates
• Ensures the system works reliably

What Are the Main Responsibilities of an MLOps Engineer?

The daily work of an MLOps Engineer can vary depending on the organization, but several responsibilities are common across industries.

1. Deploying Machine Learning Models

One common responsibilities of an MLOps Engineer is moving machine learning models from development environments into production systems. A model created by a data scientist may work well on a computer during testing. However, businesses need it to operate within real applications. Deployment involves:

• Preparing the model for use
• Connecting it with existing systems
• Managing technical requirements
• Supporting reliable operation and performance

For example:

A company creates an AI chatbot for customer support. The MLOps Engineer helps make the chatbot available on the company website and ensures it can handle customer requests efficiently.

2. Automating Machine Learning Workflows

MLOps Engineers use automation to reduce manual work and improve reliability. Machine learning projects often involve repeated tasks, such as:

• Collecting data
• Training models
• Testing updates
• Deploying new versions

Instead of completing these tasks manually each time, MLOps Engineers create automated workflows. Automation can help teams:

• reduce repetitive manual work;
• reduce some types of human error;
• standardise workflows; and
• deploy tested updates more efficiently.

For example: A financial company may update its fraud detection model every month. Automation allows the team to test and deploy new versions more efficiently.

3. Monitoring AI Model Performance

Machine learning model performance can degrade when the data encountered in production differs from the data used during development. This may involve data drift, concept drift or changes in the environment in which the model operates. This happens because real-world data changes. For example: A language translation model trained on older language patterns may become less effective as new terms and expressions appear. MLOps engineers monitor the following:

• Model accuracy
• System performance
• Data quality
• User interactions

If problems appear, they work with other AI professionals to improve the system.

4. Managing Data Pipelines

Machine learning models depend heavily on data. Poor-quality data can lead to inaccurate results. MLOps Engineers may help build, maintain or integrate the data and feature pipelines that support machine learning workflows, often working alongside data engineers. This includes:

• Collecting data
• Cleaning data
• Processing information
• Preparing data for models

For example:

An online retailer may collect customer search behaviour, purchase history, and product information. These data sources must be organised properly before an AI recommendation system can use them.

What Skills Does an MLOps Engineer Need?

MLOps sits at the intersection of machine learning, software engineering, and IT operations. Because of this, MLOps Engineers often develop a mix of technical and problem-solving skills rather than focusing on just one area. The exact skills required vary by role and employer, but the following areas are commonly valued.

Programming Skills

Programming is an important part of MLOps because engineers automate workflows, build deployment pipelines, and manage machine learning systems. Common programming languages include:

• Python
• Bash
• SQL
• Java (in some organisations)
• Go (for certain cloud-native applications)

For example, an MLOps Engineer might write a Python script that automatically retrains a machine learning model whenever new data becomes available. The goal is not simply to write code but to create reliable, repeatable processes that reduce manual work.

Understanding Machine Learning

Although MLOps Engineers may not spend most of their time designing AI models, understanding how machine learning works is essential. Useful topics include:

• Supervised learning
• Unsupervised learning
• Model training
• Model evaluation
• Feature engineering
• Model accuracy
• Overfitting and underfitting

For instance, if a deployed model suddenly becomes less accurate, an MLOps Engineer should understand possible causes and work with data scientists to investigate the issue.

Cloud Computing

Many AI systems run on cloud platforms rather than local computers. As a result, MLOps Engineers often work with cloud services that provide computing power, storage, and deployment tools. Examples include:

• Amazon Web Services (AWS)
• Microsoft Azure
• Google Cloud Platform (GCP)

Imagine a streaming service that serves millions of users daily. Hosting AI systems on cloud platforms allows the service to scale resources based on demand instead of relying on a single physical server.

DevOps Principles

The “Ops” in MLOps comes from DevOps, a practice that focuses on collaboration between software development and IT operations. Important DevOps concepts include:

• Automation
• Continuous Integration (CI)
• Continuous Deployment (CD)
• Infrastructure management
• Version control
• Monitoring

These practices help AI teams deliver updates more efficiently while reducing the risk of errors.

Data Management

Machine learning systems rely on high-quality data. MLOps Engineers often work with large datasets and need to understand how data is:

• Stored
• Processed
• Updated
• Validated
• Protected

For example, if duplicate or incomplete data enters a machine learning pipeline, the resulting model may produce unreliable predictions. Managing data effectively helps maintain consistent AI performance.

Communication and Collaboration

MLOps is rarely a solo role. Engineers regularly work with:

• Data scientists
• Software developers
• Cloud engineers
• Security teams
• Business stakeholders

Being able to explain technical issues clearly and collaborate across teams is an important part of the job. For example, an MLOps Engineer may need to explain why an AI model requires retraining or why additional cloud resources are needed to support increased user demand.

Tools Commonly Used by MLOps Engineers

The specific tools vary between organizations, but many MLOps Engineers use technologies that help automate and manage machine learning systems.

It is important to remember that beginners are not expected to master every tool immediately. Many professionals build these skills gradually through study, projects, and practical experience. The specific technology stack varies by organisation, and this list should not be interpreted as a required or universal MLOps toolset.

A Day in the Life of an MLOps Engineer

Many students wonder what this career looks like on a typical day. While responsibilities vary, an MLOps Engineer’s work often includes:

• Checking whether deployed AI models are performing as expected.
• Reviewing alerts from monitoring systems.
• Automating deployment processes.
• Testing updated machine learning models.
• Working with developers to solve technical issues.
• Managing cloud infrastructure.
• Improving system reliability and efficiency.

For example, an online food delivery platform may use AI to estimate delivery times. If the predictions suddenly become inaccurate because of changing traffic patterns, the MLOps Engineer may investigate the issue, coordinate with the data science team, and deploy an updated model. The work is often a balance of problem-solving, automation, and collaboration rather than building AI models from scratch every day.
