Confidencial (Apenas para Cadastrados) Concur, market leader in integrated travel, expense and invoice management, is looking for Senior Data Scientists to help make our products even stronger through data-driven insights and AI innovation! Your responsibilities will include designing and developing machine learning models, data pipelines, and analytical solutions using various tools and technologies. You will work in a great environment with many global teams to create value for our customers, delivering high-quality and innovative data science solutions. You will also help design and ship AI-driven features (predictive models, recommendation systems, and automated analytics), ensuring they are production-ready, scalable, and compliant with privacy and fairness requirements.

Value You Deliver

• Lead data science initiatives for complex business problems from research to production deployment

• Design and implement end-to-end ML pipelines with advanced patterns: feature engineering, model validation, A/B testing, model monitoring, automated retraining, and performance optimization

• Deploy and scale ML model-serving solutions (MLflow, Kubernetes-based serving, real-time inference endpoints) and optimize for accuracy, latency, and cost

• Develop statistical models and deliver insights as part of an agile data science team

• Mentor and lead team members by setting positive examples and technical guidance in statistical methods and ML best practices

• Own data science solutions end-to-end, implementing scalable ML systems using AWS services like SageMaker, EMR, Redshift, and S3

• Integrate LLM (Large Language Models), implement RAG (Retrieval-Augmented Generation), and develop embedding-based solutions

• Implement advanced prompt engineering, model fine-tuning, and automated evaluation frameworks

• Build intelligent conversational agents and leverage them to enhance user interactions through natural language understanding and context-aware responses

Position Requirements

• Bachelor’s degree or equivalent in a quantitative field (e.g., Data Science, Statistics, Mathematics, Computer Science, Engineering, etc.)

• Proficient in Python with experience in ML libraries (scikit-learn, TensorFlow, PyTorch, pandas, numpy)

• MLOps mentality with understanding of model versioning, CI/CD for ML, and model observability

• Experience with Docker, Kubernetes, and cloud platforms (AWS SageMaker, EC2, S3, etc.)

• Statistical expertise in experimental design, hypothesis testing, and causal inference

• Hands-on experience with cloud-native ML solutions and distributed computing frameworks

• Practical experience integrating LLMs or building embedding-based solutions (OpenAI, Anthropic)

• Experience with AI-assisted development tools (ClaudeCode, Copilot, Cline) to improve development efficiency and automated ML workflows

• Deep understanding of MLOps concepts: model tracking, data drift detection, automated retraining, and model governance

Value Competencies:

• Build strong relationships and a positive work environment together.

• Grow professionally and deliver excellence with responsibility.

• Make impact visible and recognized across the organization.

The ideal candidate will have a passion for delivering optimal solutions and challenging the status quo. To be successful in this role, you will thrive in an agile environment where teams work together toward a common goal.
