Deep Learning Engineer vs. Machine Learning Engineer: Key Differences
It’s easy to confuse deep learning engineers with machine learning engineers. After all, both work in AI and use data to build predictive models. But while their roles overlap, the differences matter, especially when you're hiring for a specific project or business need.
Machine learning engineers focus on a broader range of algorithms, such as decision trees, regression models, clustering, and ensemble methods, that can work well with smaller datasets and more structured data. They often handle data preprocessing, feature engineering, and model tuning using a variety of traditional ML techniques.
Deep learning engineers, on the other hand, specialize in building and scaling neural networks, especially deep architectures like convolutional neural networks (CNNs), recurrent neural networks (RNNs), and transformers. These models are ideal for processing unstructured data like images, videos, audio, or natural language, and they often require more computing power, bigger datasets, and advanced architectures.
Here’s a side-by-side comparison of both roles.
Understanding this distinction can help you hire the right talent for the job. If your project involves heavy computation, deep unstructured data, or advanced AI architecture, you’ll want a deep learning engineer leading the way.
How Much Does a Deep Learning Engineer Cost? U.S. vs. Latin America
Deep learning talent doesn’t come cheap, especially in the U.S., where demand often exceeds supply. According to industry benchmarks, a senior deep learning engineer in the U.S. can easily command a six-figure salary, with total compensation packages soaring past $200,000 at top tech firms. For startups and growing companies, that kind of price tag can be a major barrier to building out an AI team.
That’s why many U.S. businesses are turning to Latin America to hire remote deep learning engineers. With a growing pool of AI talent, strong university systems, and time zone compatibility, countries like Brazil, Argentina, and Colombia offer a compelling blend of quality and affordability. And thanks to nearshoring, communication and collaboration are seamless, unlike with more distant offshore models.
Here’s a salary comparison to give you a clearer picture:
These figures reflect full-time remote employees working with U.S. companies. While compensation varies by country, experience, and skill set, hiring from Latin America can reduce costs by 50–60%, without compromising on quality.
And when you partner with a vetted hiring platform that specializes in AI and deep learning roles, you also save time on sourcing, vetting, and onboarding top-tier talent.
Where to Find and Hire the Right Deep Learning Talent
Finding a qualified deep learning engineer is about connecting with talent that’s not only technically skilled, but also aligned with your goals, time zone, and communication style. And in 2025, that often means expanding your search beyond the U.S.
While hiring locally can work for some, the cost and competition for AI talent in the U.S. are higher than ever.
Here are your top hiring options:

- Problem-solving mindset – Present a high-level business challenge and ask how they’d approach it with AI. You’re assessing creativity, feasibility, and clarity of thought.
- Data pipeline awareness – Ask how they manage and prepare data before training. Consider preprocessing, augmentation, normalization, etc.
Red Flags to Watch Out For
- Overemphasis on theory, light on application – Some candidates know the math but haven’t shipped real models.
- Limited collaboration experience – Deep learning projects often involve cross-functional teams. Poor communicators can stall progress.
- No familiarity with deployment tools – If they’ve never moved a model from Jupyter Notebook to production, that’s a gap.
- “One-framework-fits-all” mindset – Strong engineers tailor their stack to the problem, not the other way around.
- Vague answers to project-specific questions – A clear red flag that experience might be overstated.
To streamline this process, consider partnering with a firm that pre-vets deep learning engineers, especially if you're hiring remotely or nearshoring to Latin America. It saves time, reduces risk, and increases the odds of finding someone who’s both technically sharp and business-aware.
The Takeaway
Deep learning engineers are essential for companies looking to compete with AI-driven innovation. From building intelligent products to automating processes and unlocking the full potential of your data, the right deep learning expert can be a true growth accelerator.
