Remote Senior Data Scientist

Summary

Join a company that cares about wellbeing and is hiring a Senior Data Scientist to its Partner Content team in Brazil. As a Data Scientist, you will play a crucial role in applying AI models to generate content, leverage existing data, and gather additional data to understand user behavior and preferences. You will collaborate with a multidisciplinary team of engineers, PMs, and Tech Leads to create innovative AI applications that solve real-world problems.

Requirements

• Bachelor's or Master’s degree in Computer Science, Data Science, Machine Learning, Statistics, or a related field
• Proficiency in Python and experience with machine learning frameworks such as TensorFlow, PyTorch, or similar
• Knowledge of generative models, including GANs, VAEs, autoregressive models, and transformers
• Strong problem-solving abilities, with a focus on experimental design and data analysis
• Excellent verbal and written communication skills (both in English and Portuguese), with the ability to explain complex technical concepts to non-technical stakeholders

Responsibilities

• Apply AI models that can generate content leverage existing data (reviews, check-ins, partner usage, time/consistency patterns) and gather additional data to understand user behavior and preferences
• Collaborate with a multidisciplinary team of engineers, PMs, and Tech Leads to create innovative AI applications that solve real-world problems
• Identify opportunities to use GenAI to address business challenges, enhance existing processes, or create innovative solutions
• Provide data insights and support product decisions leveraging existing data or gather additional data to understand user behavior
• Fine-tune pre-trained models to adapt to specific use cases and requirements, including performing large language models (LLMs) fine-tuning and optimization for enhanced model performance
• Develop and refine prompts to enhance the performance and output quality of generative models
• Collect, preprocess, and analyze large datasets to ensure high-quality input data for training generative models
• Develop and utilize embeddings to represent complex data types (e.g., text, images) in a way that facilitates the generation of meaningful and accurate outputs
• Stay current with the latest research in generative AI, propose new approaches, and contribute to the academic and technical community through publications and presentations
• Work closely with cross-functional teams to integrate generative models into products and services, ensuring they meet business objectives and user needs
• Develop and implement rigorous testing and evaluation frameworks to assess model performance, robustness, and reliability
• Maintain comprehensive documentation of models, algorithms, experiments, and processes to ensure reproducibility and knowledge sharing

Preferred Qualifications

• Proficient in model fine-tuning and hyperparameter optimization
• Proven track record of developing and deploying generative AI models in production
• Familiarity with natural language processing (NLP) and/or computer vision applications
• Familiarity with vector databases for handling high-dimensional data
