Domain Roadmap

MLOps Engineer

MLOps applies DevOps discipline to machine learning — turning notebooks and one-off models into pipelines, services, and systems that stay reliable in production. This roadmap walks you from ML and data engineering fundamentals through experiment tracking, model serving, orchestration, and the monitoring and governance practices that keep a model trustworthy long after launch day.

What does an MLOps Engineer actually do?

The bridge between a model that works on a laptop and one that works in production

Training a good model is only part of the problem — the harder part is often getting it into production reliably, keeping it fed with fresh data, watching it for drift, and rolling out updates without breaking anything. That's the gap MLOps exists to close.

It sits at the intersection of data engineering, software engineering, and DevOps — building the pipelines that move data and models through training, versioning, deployment, and monitoring, usually on top of cloud infrastructure and containers.

You don't need to be a research scientist to do this work well. Solid programming and infrastructure skills, a working understanding of how models are trained and evaluated, and comfort with distributed systems matter more than deep ML theory day-to-day.

Frequently Asked Questions

Common questions from people starting out with MLOps

Do I need to be a data scientist before becoming an MLOps engineer?

No. Many MLOps engineers come from a DevOps or backend engineering background and pick up enough ML fundamentals to work effectively with data scientists — a working understanding of how models are trained and evaluated matters more than the ability to design new architectures.

What's the difference between MLOps and DevOps?

DevOps focuses on shipping and operating software reliably. MLOps borrows that discipline but adds concerns specific to ML — data versioning, experiment tracking, model drift, and retraining — that don't exist in traditional software deployment.

Is Kubernetes required for MLOps?

Not strictly, especially for smaller teams using a managed cloud ML platform, but it's extremely common at scale for orchestrating training jobs and serving infrastructure, and most MLOps job postings expect at least working familiarity with it.

Which cloud ML platform should I learn first?

Whichever your target employer uses is the practical answer, but AWS SageMaker has the widest market share and documentation, making it a reasonable default to start with if you don't have a specific employer in mind.

What is model drift, and why does it matter?

Drift is when the statistical properties of incoming data — or the relationship between inputs and outputs — shift away from what a model was trained on, quietly degrading its accuracy. Monitoring for it is what lets a team catch a failing model before its predictions cause real damage.

What's LLMOps, and how does it relate to MLOps?

LLMOps is MLOps applied specifically to large language models — it shares the same core practices (versioning, monitoring, CI/CD) but adds concerns like prompt management, retrieval pipelines, and evaluating generative rather than purely predictive outputs.

Track complete

From data pipelines and experiment tracking to model serving, orchestration, and drift monitoring — that's the core of what's expected of a production MLOps engineer. Keep building, and put it to work on a real model.
