You will work on one of the most challenging and rewarding problems in the industry: finding the right price, for the right customer, at the right time. Your work will ensure that the airline's Revenue Optimization remains scientifically robust, operationally scalable, and commercially impactful, directly shaping how revenue is optimized in a dynamic, competitive marketplace. 

Your responsibilities will center on turning business challenges into well-defined analytical problems and building end-to-end machine learning solutions that deliver measurable impact. You will design, train, and maintain models that power SAS's revenue optimization, ensuring they are accurate, scalable, and production-ready. 

A priority will be to deliver dynamic pricing, a groundbreaking shift in how SAS competes in the marketplace. At the same time, we are developing AI-driven revenue optimization at scale, ensuring our models continuously learn, adapt, and evolve with industry dynamics. 

Your work will help SAS unlock the full potential of AI in airline revenue optimization, making smarter pricing and network decisions a reality today. 

Challenges You Will Work On

Machine Learning & Optimization Techniques 

Build and deploy algorithms that power revenue and network decisions. Among other solutions, you'll develop demand forecasting, purchase probability, and revenue optimization models, leveraging a broad spectrum of AI methods. 

From classical ensemble methods to deep learning architectures and reinforcement learning frameworks, you'll select the most effective approach for each complex problem. 

Operations Research 

Beyond building models, you'll explore new formulations, test novel algorithms and findings that push the boundaries of airline revenue optimization. 

You will convert advanced research into production-ready optimization and modeling solutions, collaborating with the Operations Research team to embed novel algorithms into initiatives that deliver measurable business impact. 

MLOps 

Leverage end-to-end ML infrastructure to take models from research to production at scale. This includes designing reproducible training and inference pipelines, integrating CI/CD workflows for seamless deployment, and ensuring robust monitoring to detect drift and trigger automated retraining, keeping models stable and accurate in production.
