  • Jefferson

    Data Scientist

    Brazil/(GMT -3:00)

    Jefferson is a Senior AI Engineer with 11+ years rooted in NLP and computational linguistics — a rare foundation that shapes how he approaches LLM systems at the data layer, retrieval design, and evaluation. He covers the full AI engineering stack: agentic orchestration (LangGraph, CrewAI, AWS Bedrock AgentCore), RAG pipelines with chapter-aware chunking and semantic retrieval surfaces, and multi-model GenAI workflows with structured quality evaluation. He's taken sole architectural ownership of production agentic platforms at enterprise scale, and brings genuine pre-transformer NLP depth — spaCy, BERT, NER, classical ASR — that most LLM engineers simply don't have. Best fit as the AI/NLP design lead on a RAG or agentic product where retrieval architecture and orchestration quality matter more than raw Python backend throughput.

The lemon tea

Why hire Data Science developers through our platform?

Find devs with skills you can trust with Lemon.io, so you can stop looking and start making progress again.

What you should know about modern Data Science devs

When you’re slogging through the process of hiring Data Scientists, everything slows down. Your team interviews, vets, and discusses every candidate, keeping them from doing their jobs. Our streamlined hiring process accelerates and simplifies recruitment, allowing your team to return to their jobs.

Quality talent

Every one of our 1300+ senior engineers has progressed through four levels of vetting, so you can be confident you’re hiring quality.

Faster hiring

We match your startup with a list of devs that meet your requirements within 48 hours, so you can focus on your GTM roadmap.

100% Guaranteed

If, for whatever reason, you aren’t completely satisfied with your engineer, we’ll match you with another free of charge.

Connect to an ocean of talent

You want to hire Data Scientists who perfectly match your needs. Remote talent gives you an almost endless selection so you can find your perfect dev.

Find affordable talent

The high cost of living in cities makes hiring prohibitively expensive. Look beyond your backyard for talent with all of the skills at a third of the cost.

Build agility into your hiring

Match the size of your team to the size of your project. When there’s too much work, remote contractors add resources to your team on call, then disappear after.

Lower fixed overhead costs

Every in-house hire comes with hidden costs – work spaces, computers, desks. Remote contractors supply their own, helping you lower your office costs.
