ML Engineer [AI Team]

Company: Banco Plata Employment type: FULL_TIME

About the team

AI Platforms builds the shared AI foundation for Plata, helping product and business teams launch AI solutions faster. We create reusable platforms and tools used across customer care, operations, compliance, telesales, and more. We work with AWS, Go, Python, and cloud models, combining off-the-shelf solutions with custom infrastructure — including copilots, agents, RAG, voice/OCR services, AI gateway, and ML pipelines.

About the role

We’re looking for a Middle+/Senior Applied ML Engineer to build and optimize ML solutions for real business use cases. You’ll work on OCR, ASR, LLMs, and classification tasks — focusing on training, fine-tuning, data quality, and production readiness.

Challenges that await you

• Train, fine-tune, and adapt models for practical internal use cases
• Work on ASR-related tasks, including model training, improvement, and practical adaptation to product needs
• Work with datasets end to end: define data requirements, prepare and structure data, support labeling workflows, and improve data quality
• Optimize models for practical use, including performance, efficiency, and quality trade-offs
• Collaborate with engineers to bring trained or adapted models into real production use cases

What makes you a great fit

• Demonstrated experience in deep learning and transformers models
• Strong experience with Automatic Speech Recognition (ASR) systems
• Proficiency in frameworks like PyTorch
• Understanding of how model quality depends on dataset design, labeling quality, and data preparation
• Ability to go deeper than standard training notebooks and make informed decisions during training and optimization
• Strong foundation in data structures, algorithms, and software engineering principles
