Overview WELCOME TO SITA At SITA, we keep airports moving, airlines flying smoothly, and borders open. Our technology and communication innovations power the success of the global air travel industry. You'll find us in 95% of international airports, working closely with over 2,500 transportation and government clients. Each partnership brings unique challenges, and we thrive on delivering fresh solutions and cutting-edge tech to keep operations running like clockwork. We don't just move the world forward-we're proud to be recognized as a Great Place to Work® by 79% of our employees and certified in most of our growing locations. Here, we feel empowered, supported, and inspired to grow. Are you ready to love your job? The adventure begins right here, with you, at SITA. PURPOSE As an Optimization Scientist, you will apply operations research and mathematical optimization to design and build the optimization engines that recover airline operations from disruption — turning hours of manual replanning into minutes of high-quality, automated recovery decisions. You will be accountable for a disruption-recovery solver pipeline end-to-end: from mathematical formulation to production code running against real airline operations. Reporting to the Head of Disruption Management Solutions (OCC Assistant Manager), you will be a part of the OCC Assistant Manager team responsible for OCC Assistant Manager, SITA’s AI-powered Operations Control Center solution that helps airlines manage and recover from operational disruptions. We are hiring two Optimization Scientists to grow the team. KEY RESPONSIBILITIES Own a disruption-recovery solver pipeline end-to-end — from mathematical formulation to production code Translate airline-specific rules and constraints (crew legality, aircraft routing, passenger reaccommodation) into solver formulations Validate solver solutions against real disruption cases, working side by side with our Solutions Experts Own solution-quality and runtime KPIs, driving the trade-off between solution quality and solve time Extend solver capabilities and ship new optimization functionality as the product evolves Collaborate with Back-End and Data Engineering teams to integrate your solver outputs into the live product Build deep airline-operations domain knowledge and turn it into better formulations Qualifications WHO YOU ARE You have a strong foundation in mathematical optimization and operations research, with depth in areas such as linear programming, mixed-integer programming, network flow algorithms, large-scale optimization techniques or metaheuristics You have hands-on experience with solvers such as Gurobi, CPLEX or SCIP You are proficient in Python and SQL, work fluently with Git and optimization libraries, and write code that is ready for production You can translate complex business rules into algorithms You work at the intersection of math and engineering, bridging OR theory and production code You are self-directed and ramp up new domain knowledge independently You are detail-oriented — debugging solver behavior requires precision You think in systems: you understand how formulation choices affect solver performance end-to-end You hold a degree in Operations Research, Applied Mathematics, Computer Science, Industrial Engineering or a related quantitative field. MSc or PhD is a plus. ABOUT YOUR SKILLS You possess Airline Operations Management knowledge and understand the operational, commercial, and customer service challenges faced by airlines. NICE-TO-HAVE Experience with column generation or decomposition methods C++ programming skills Familiarity with airline operations: IROPS/disruption management, crew legality rules, aircraft rotations or passenger rebooking WHAT WE OFFER We're all about diversity.
