About this role

Truelogic is hiring a Senior Data Scientist in Santo Domingo to build natural language processing models that detect security risks in artificial intelligence interactions. This position suits an experienced machine learning professional with a background in transformer-based architectures and security concepts.

Role Overview

Truelogic seeks a Senior Data Scientist to join a core artificial intelligence team focused on helping organizations safely adopt and manage technology at scale. The professional will work on data curation, model development, evaluation, and optimization to identify potential risks in artificial intelligence interactions such as sensitive data exposure and malicious prompts.

Key Responsibilities

Build, curate, clean, and maintain datasets for natural language processing and artificial intelligence security use cases.
Generate and augment synthetic datasets using large language models to cover edge cases and improve model robustness.
Train, fine-tune, and evaluate natural language processing and transformer-based models for real-time risk detection and classification.
Develop and improve custom classifiers and Named Entity Recognition models for identifying relevant information.
Design evaluation pipelines and benchmarks to measure model quality, accuracy, false positives, and performance.
Experiment with modeling approaches and continuously improve models as new threats emerge.
Optimize models and inference workflows for production environments where speed and efficiency matter.
Collaborate with engineering and artificial intelligence teams to move models from research into production solutions.
Analyze model performance and datasets to identify gaps and opportunities for improvement.
Contribute to the development of practical workflows, documentation, and best practices.

Requirements

Minimum of 4 years of professional experience as a Data Scientist, Machine Learning Engineer, or closely related role.
Hands-on experience with natural language processing, transformer-based models, and modern language model architectures.
Programming skills in Python.
Experience with machine learning and deep learning frameworks like PyTorch and TensorFlow.
Experience with libraries such as Hugging Face and scikit-learn.
Experience training, fine-tuning, or adapting machine learning models for real-world applications.
Experience working with Named Entity Recognition, tokenization, text classification, or other natural language processing techniques.
Data preparation and analysis skills using Pandas or similar tools.
Experience designing model evaluations, benchmarks, and experiments.
Understanding of model performance and inference optimization techniques.
Familiarity with artificial intelligence security concepts like prompt injection, personal identifiable information exposure, and adversarial inputs.
Problem-solving skills and the ability to work independently on ambiguous machine learning problems.
