About The Position

At RTX, the world largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines and auxiliary power systems and has been revolutionizing modern flight for over 100 years. Join us and help shape the future of aerospace and defense. What You Will Do Pratt & Whitney, an RTX Company is looking for a Software Engineer to join our Real-Time Test Systems Software (RTSS) team. This individual will work closely with a team of software engineers in the delivery of developing, enhancing, and implementing software solutions within the RTSS Portfolio, as well as integrations with other Pratt & Whitney products. These software solutions will maintain functionality and enhance features for real-time data visualization and monitoring software systems. As a software engineer in the Real-Time Test Software Systems team, you will become familiar with how Pratt & Whitney executes engine test campaigns and advances the next generation of jet engines. Multi-disciplinary collaboration will teach you how to collaborate with engine test operations teams and efficiently perform real-time troubleshooting techniques for complex software systems. You will master the art of building low-latency data pipelines that process thousands of engine sensor events per second, turning raw vibration, thermals, pressures, and speeds into actionable, live intelligence. Ultimately, you will gain hands-on experience in guaranteeing data integrity in critical, event-driven systems to ensure the health and safety of our next-gen engines.
