What will you bring to the team?

• Professional experience in Operations Research or a related field.
• Practical knowledge of OR techniques and the ability to explain the consequences of using different approaches (e.g., metaheuristics vs. exact approaches).
• Experience with Java. Knowledge of Python is a plus. Understanding of efficient data structures and deployment pipelines.
• Willingness to learn GitHub workflows, containerization, and cloud environments (e.g., Google Cloud, AWS).
• A focus on high-quality processes, documenting them clearly, and learning best practices from peers.
