As a Software Engineer on the Aviation Intelligence team, you'll design, build and code critical projects — real-time data streaming and inference, high-throughput data availability, AI/ML, and turning raw data into real insight — while helping plan and communicate the work along the way. We're a small team inside a large org, and this role is meant to grow into someone who brings ideas to the table, not just executes on them.
Here's why you might like it: the datasets are genuinely very large, so you get to leverage niche technologies for large datasets and get to flex your math/stats skills from time to time. Performance and efficiency aren't nice-to-haves here, they're fun problems. Much of what we work on is open-ended — and "can this even be solved," is a question that one must enjoy trying to answer. Improvements in our products directly improve the status quo for aviation around the world: airlines and airports run on our predictions, so real people catch flights they'd otherwise miss and skip delays they'd otherwise sit through — without ever knowing your work is why. You don't get many shots at impacting an entire mode of transportation. This is one of them.
Qualifications You Must Have:
Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience oran Advanced Degree in a related field and minimum 5 years of experience
Must be authorized to work in the U.S. without sponsorship now or in the future. RTX will not offer sponsorship for this position.
