We are seeking a Senior Data Scientist to contribute to our next level of growth and expansion.
What is this position about?
This role is focused on designing, developing, and deploying advanced Computer Vision and multimodal AI solutions for real-world business problems. The Senior Data Scientist will work end-to-end, from data exploration and model development to production deployment, collaborating with cross-functional teams and clients across LATAM.
You can work remotely, or you’re welcome to join our offices if you’re based in Colombia or Uruguay.
Job Description
Design, develop, and deploy end-to-end Computer Vision solutions using classical and deep learning approaches.
Build and optimize models for image classification, object detection, segmentation, and OCR/document understanding.
Apply CNN architectures (e.g., ResNet, EfficientNet, ConvNeXt) and Vision Transformers (ViT, Swin), including transfer learning and fine-tuning strategies.
Collaborate on data annotation strategies, data augmentation pipelines, and approaches to handle imbalance, noise, and domain shift.
Evaluate model performance using appropriate metrics (mAP, IoU, Dice, ROC) and perform detailed error analysis.
Implement model explainability and interpretability techniques such as Grad-CAM and saliency maps.
Optimize models for production environments, including quantization, pruning, and inference optimization (real-time vs batch).
Work closely with engineering teams on MLOps practices: monitoring drift, data lineage, and retraining loops.
Contribute to multimodal and GenAI initiatives, including vision-language models, vision in RAG systems, and image-based prompting.
Ensure ethical AI practices, considering privacy, PII, dataset bias, and regulatory constraints.
Qualifications
Strong foundations in Computer Vision, including image formation, color spaces, and geometry.
Solid understanding of classical CV methods (filters, edge detection, feature extraction – conceptually).
Hands-on experience with deep learning for vision and modern architectures.
Experience working with production ML systems and MLOps best practices.
Ability to communicate technical concepts clearly to both technical and non-technical stakeholders.
Strong problem-solving skills and ownership mindset.
Experience mentoring or guiding junior team members is a plus.
What about languages?
Advanced English proficiency is required for effective communication with international teams and stakeholders.
