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 spanet 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.

• Software Development & Optimization: Design, develop, and optimize data visualization and monitoring software to meet real-time performance constraints while following coding standards and best practices.

• Real-Time Data Processing: Develop high-speed data flow pipelines to ensure the software meets strict real-time performance requirements, including determinism, low-latency computation, and efficient memory management.

• Advanced Signal Processing Algorithms: Implement and refine rate conversion, filtering, correlation, windowing, decimation, interpolation, and other real-time signal processing techniques, ensuring data accuracy and usability.

• Linux Systems Administration & Development: Develop, debug, and optimize software on Linux.

• Project Management & Agile SDLC: Support all phases of software development, including requirements gathering, architecture design, testing, deployment, and maintenance towards timely, iterative releases.

• Team Collaboration & Communication: Work closely with customers, stakeholders, and developers to understand system needs, troubleshoot issues, enhance user experience, socialize designs, and integrate changes as appropriate with rapid iterations.

• Defect Testing & Troubleshooting: Develop test cases and leverage static/dynamic analysis tools for verifying real-time performance, ensuring signal integrity, identifying potential issues, diagnosing issues, and resolving defects.

• Documentation & Compliance: Create project/technical documentation and ensure compliance with industry standards and best practices

Qualifications You Must Have

• Bachelor’s Degree in Science, Technology, Engineering or Mathematics (STEM)

• 2 years of software engineering experience or an Advanced Degree in STEM with a GPA of 3.0 or higher

Qualifications We Prefer

• Advanced Software Development: Experience with modern C++, Qt, SQL, Perl, Bash for both UI and real-time system development.

• DSP & Computational Algorithms: Understanding fundamentals of linear algebra, Fourier transforms, filtering techniques, signal processing algorithms, frequency analysis, etc.

• Real-Time & High-Performance Systems: Experience developing software that leverages multi-threading, performance profiling, event batching, stream processing, etc. to satisfy strict real-time constraints and minimize latency across both Windows and Linux platforms.

• Linux System Administration, Development, & Optimization: Experience with Linux system programming, networking, and command-line tools for troubleshooting.

• Data Acquisition Hardware: Exposure to turbomachinery sensors (e.g. strain gauges), ADCs, oscilloscopes, logic analyzers, multimeters, power supplies, and signal generators.
