What types of AI training tasks can these specialists handle?

RLHF annotation, pairwise preference labeling, instruction fine-tuning dataset creation, prompt engineering, red-teaming, evaluation benchmark construction, and data pipeline QA.

Do AI trainers need to be domain experts?

It depends on your task. We can source generalist annotators for broad instruction-following tasks, or domain specialists (e.g., coding, medicine, law, math) for more technical annotation work.

Can I hire AI trainers on a project basis instead of full-time?

Yes. AI trainers are available for both full-time dedicated placements and fixed-duration project engagements. We scope both models depending on your annotation volume.

How is annotation quality ensured during the vetting process?

We design task-specific quality tests in collaboration with you during kickoff. Candidates complete these tests and results are graded before profiles are presented.

Full-Time Hiring.

What is the Hire AI Trainers service?

Hiring AI trainers through NeuronHire means accessing a curated pool of Latin American engineers and specialists with hands-on experience in reinforcement learning from human feedback (RLHF), prompt engineering, pairwise preference labeling, and fine-tuning data pipeline construction. Trainers are vetted on domain knowledge, English communication, and annotation quality benchmarks not just general coding skills. Placements are available full-time or project-based, at 30–50% below comparable US AI training talent costs.

When is this the right solution?

Hire AI Trainers works best in these situations.

You're building RLHF datasets

You need trainers who understand model alignment, can write high-quality preference pairs, and apply consistent annotation guidelines at scale.

You need prompt engineering specialists

Your team is iterating on LLM prompts and needs engineers who deeply understand model behavior, chain-of-thought prompting, and evaluation frameworks.

You're scaling a fine-tuning pipeline

You have a working fine-tuning approach and need reliable data engineers to build, maintain, and quality-check the pipeline end-to-end.

How it works

Scope alignment

We define your AI training task, annotation guidelines, tooling, and quality metrics in a 30-minute call.

Specialist sourcing

We search our network for trainers with relevant domain experience AI, coding, science, or domain-specific annotation.

Quality vetting

Candidates complete annotation quality tests specific to your task before you see their profiles.

Placement & onboarding

You run a final interview, then your AI trainer starts full-time or project-based, as agreed.
