Machine Learning and AI Engineer Requirements in 2026: The Skills Companies Ask For Most
The most common requirements for machine learning and AI engineers in 2026 are machine learning fundamentals and Python, each required in about 57% of roles, followed by LLM experience, PyTorch and system design. AI engineering is also the highest-paying engineering title we analyzed, and it asks for senior experience more often than other roles.
We analyzed open machine learning and AI engineering roles at companies hiring through Refer in the US, separating each job description’s requirements from its nice-to-haves.
TL;DR
- Machine learning and Python are each required in about 57% of roles.
- LLMs and generative AI are required in about 34% of roles and listed as a bonus in about another 21%.
- PyTorch (about 29%) and system design (about 26%) come next.
- About 33% of roles ask for 6 or more years of experience.
- The median posted salary range centers around $210,000, the highest of any engineering title we analyzed.
What Do ML and AI Engineer Roles Require?
| Requirement | Required in |
|---|---|
| Machine learning | About 57% of roles |
| Python | About 57% |
| LLMs or generative AI | About 34% |
| PyTorch | About 29% |
| System design or architecture | About 26% |
| Degree in computer science or a related field | About 19% |
| AWS | About 18% |
| C++ | About 15% |
| APIs | About 15% |
| Kubernetes | About 14% |
| Distributed systems | About 12% |
Nice-to-haves to know: LLM experience is a bonus in about another 21% of roles, so in total more than half of AI roles mention it.
How Much Experience Do ML and AI Roles Ask For?
| Years of experience required | Share of roles |
|---|---|
| 0 to 2 years | About 14% |
| 3 to 5 years | About 53% |
| 6 years or more | About 33% |
The median is about five years, but AI roles skew more senior than software engineering overall.
Are AI Engineering Jobs Remote?
About 19% of roles are fully remote and about 22% are hybrid. Most AI teams prefer people on site.
How Much Do ML and AI Engineers Earn?
The median posted base salary range centers around $210,000, and the middle half of roles fall roughly between $185,000 and $260,000, before equity and bonuses.
How Do You Stand Out as an ML or AI Engineer?
- Show production, not just research. Describe a model or LLM feature you shipped and how it performed.
- Be specific about LLM work: retrieval, evaluation, fine-tuning or agents, and the trade-offs you made.
- Show the engineering: data pipelines, serving and monitoring.
“I built and shipped the retrieval and evaluation pipeline for our support assistant, cut hallucinated answers by 40% with an automated eval suite, and served it on Kubernetes.”
How Can Refer’s Lia Help?
Refer’s AI career agent, Lia, matches ML and AI engineers on each role’s real requirements and introduces them directly to engineering leaders, CTOs and founders.
- Double opt-in: she connects you only when you and the company both say yes.
- Discreet: your profile is hidden from your current and past employers.
- Proven: Lia has made more than 5,000 introductions.
Refer is free to use, and you pay only if you’re hired through one of Lia’s introductions, because that makes the incentive 100% aligned with getting you hired. Get started with Lia.
How-To: Show You Meet ML and AI Requirements in 5 Steps
You don’t need to rewrite your resume for every role. Keep one accurate resume that reflects what you’ve actually done, and use these steps to prepare for the conversations that follow.
- Know where you match. ML fundamentals and Python are required in most roles.
- Detail your LLM work. More than half of AI roles mention it.
- Name your framework. PyTorch is the most requested.
- Prepare a system design story. Serving, scale and monitoring.
- Show production impact. Metrics, not just models.

How We Got These Numbers
We analyzed open US machine learning and AI engineering roles at companies hiring through Refer, in October 2026, selected by job title. Our AI splits each job description into requirements and nice-to-haves; we counted how often each skill appears in each section. Pay is the midpoint of posted base salary ranges. Percentages are rounded to the nearest whole number. Figures reflect roles on Refer, not the entire market.
