Applied ML Engineer (Speech/ASR/LLMs) - Senior

? Remote – Argentina/Brazil

? Full-time

About The Role

We’re looking for an Applied ML Engineer to lead the development and operationalization of machine learning models powering real-world AI products.

The primary focus of the role will be building and improving speech-to-text (ASR) systems for medical conversations in Brazilian Portuguese and Latin American Spanish, while also contributing to LLM fine-tuning, clinical classifiers, and production ML infrastructure.

This is a highly hands-on role focused on taking models from experimentation to production.

What you’ll do

- Design, train, fine-tune, and deploy ML models for speech and language applications

- Build and maintain training pipelines and evaluation frameworks

- Work on ASR systems for domain-specific medical conversations

- Develop and improve data pipelines and ML infrastructure

- Collaborate on LLM fine-tuning and classifier development

- Optimize model performance, reliability, and scalability

- Partner with product and domain teams to translate business needs into ML solutions

- Contribute to production deployment and monitoring of ML systems

What we’re looking for





- Strong experience building and operationalizing ML models in production

- Hands-on experience with:

- ASR / speech models / audio ML

- PyTorch or modern ML frameworks

- ML infrastructure and distributed training

- Experience building:

- training pipelines
- evaluation frameworks
- production ML workflows

- Strong programming skills in Python

- Ability to work independently in ambiguous environments

- Experience collaborating across technical and non-technical teams

Nice to have

- Experience with:

- LLM fine-tuning
- orchestration frameworks
- clinical or healthcare data

- Experience building data flywheels or feedback loops

- Experience with GPU orchestration and experiment tracking

- Fluency in Portuguese and/or Spanish

Work model

- Remote – Americas

- Preference for candidates located near São Paulo or Medellín (not mandatory)

- Full-time

? Note

This is an applied ML engineering role, not a pure research position. We are looking for builders who can take models from experimentation through deployment and production operation.
