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 or an 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.
• Intermediate or better knowledge of Rust.
• Python experience.
• Experience with Unix-style systems (ability to do basic administration, and manage work upon)
• Hands-on Kubernetes experience operating production workloads.
• Experience building and maintaining CI/CD pipelines (GitLab, GitHub Actions, or similar).
• Ability to work within an agile development style.

Qualifications We Prefer:

• Experience with AWS (EKS, IAM, VPCs, networking).
• Experience with Terraform for infrastructure as code.
• Experience with Kafka.
• Experience with Nix
• Solid understanding of distributed systems, reliability, and scaling.
• Experience with observability stacks (Prometheus, Grafana, Thanos, etc.).
• Familiarity with Dagster, Airflow or other modern ETL orchestration tools.
• Background in ML/AI systems in production (MLOps).
• Experience optimizing infrastructure for performance and cost.
• Familiarity with Iceberg, Spark, Elasticsearch and other large-scale data processing systems.
• Experience working in hybrid infrastructure environments (cloud + on-prem Kubernetes).
