🧠 Data Scientist

📍 Lisbon (Hybrid)

At wBrain, we are looking for a Data Scientist to join a strategic project based in Lisbon (hybrid model). This role will contribute to high-complexity analytical environments, with a strong focus on Machine Learning, GenAI, and data visualization, supporting the development of innovative and impactful solutions.

🧩 Responsibilities

• Develop advanced analytical models (e.g., combinatorial models, deep learning on structured and unstructured data).
• Implement solutions using code (R, Python) and/or leverage PaaS cloud services (preferably Azure).
• Utilize advanced analytics libraries such as TensorFlow, Keras, Caffe, and PyTorch.
• Build models or applications that integrate GenAI (e.g., LLMs or diffusion models), including:
• Text generation, summarization, contextual classification, image generation, autonomous agents, or intelligent copilots.
• Design robust pipelines that include preprocessing, fine-tuning of foundational models (e.g., LLaMA, Mistral, T5).
• Measure outcomes using specific metrics (BLEU, ROUGE, perplexity), and deploy in a controlled manner (via API).
• Ensure strong technical foundations and follow best practices in ML engineering for GenAI.
• Create interactive data visualization solutions to present complex outputs effectively.

🧠 Requirements

• Up to 10 years of experience in a similar role;
• Degree in Computer Science, Software Engineering, or a similar technical field;
• Strong written and verbal communication skills;
• Knowledge of the Energy & Utilities sector and GDPR (preferred);
• Experience working in collaborative and global teams;
• Strong analytical and problem-solving skills, with a commitment to delivery excellence;
• Experience with relational and NoSQL databases;
• Proven experience in delivering machine learning projects using Python, R, or SAS;
• Familiarity with the full model lifecycle (training, deployment, maintenance);
• Experience with ML frameworks such as PyTorch or TensorFlow;

Nice to have:

• Experience developing analytics solutions that include AI;
• Experience building interactive data visualization solutions;
• Familiarity with Agile methodologies and tools like Jira and Confluence;
• Language proficiency: English (mandatory); Portuguese and Spanish (a plus).
