What is the difference between an AI engineer and a data scientist?

Data scientists often focus on analysis and prototypes. AI and ML engineers focus on getting models into production with evaluation and monitoring. Some people cover both; say which you need in the post.

Should I hire contract or full-time for a first LLM feature?

Contract suits a scoped first path to production. Full-time suits ongoing ownership. Fractional suits senior design if delivery capacity already exists.

Can I hire an AI engineer remotely in another country?

Yes. Set overlap hours. For full-time employment abroad without an entity, teams often use Carbon's EOR partner Deel.

How to hire an AI engineer

Last updated 18 Oct 2026

An AI engineer (or ML engineer) turns a model idea into something that runs in production: data, evaluation, serving, monitoring and a clear owner when it fails.

This guide is the hiring process. Role pages: AI / LLM engineer and machine learning engineer. Engagements: full-time, contract or fractional.

Define the use case before the title

What decision or product feature improves if the model works?
What data do you already have, and who owns it?
How will you know the system is good enough (evaluation)?
Who is on-call when quality drops?

Titles vary (AI engineer, ML engineer, LLM engineer). Hire for the use case, then pick the closest title on the post.

Skills that predict success

Problem framing and honest limits of the approach.
Evaluation beyond a single accuracy number.
Production habits: serving, latency, cost, monitoring, rollback.
Data collaboration with data engineers and analysts.
Communication with product and risk owners.
