About The Position

Pratt & Whitney, an RTX Company, is seeking a Software Engineer to join the Real-Time Test Systems Software (RTSS) team. This role involves developing, enhancing, and implementing software solutions within the RTSS Portfolio and integrating them with other Pratt & Whitney products. The software solutions will maintain functionality and enhance features for real-time data visualization and monitoring systems. The engineer will gain an understanding of how Pratt & Whitney conducts engine test campaigns and develops next-generation jet engines. This position requires multi-disciplinary collaboration with engine test operations teams and involves real-time troubleshooting of complex software systems. The engineer will focus on building low-latency data pipelines that process thousands of engine sensor events per second, transforming raw data into actionable intelligence, and ensuring data integrity in critical, event-driven systems for the health and safety of next-generation engines.

Requirements

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
U.S. citizenship is required
The ability to obtain and maintain a U.S. government issued security clearance is required.
Active and existing security clearance required after day 1

Nice To Haves

Experience with modern C++, Qt, SQL, Perl, Bash for both UI and real-time system development.
Understanding fundamentals of linear algebra, Fourier transforms, filtering techniques, signal processing algorithms, frequency analysis, etc.
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.
Experience with Linux system programming, networking, and command-line tools for troubleshooting.
Exposure to turbomachinery sensors (e.g. strain gauges), ADCs, oscilloscopes, logic analyzers, multimeters, power supplies, and signal generators.

Responsibilities

Design, develop, and optimize data visualization and monitoring software to meet real-time performance constraints while following coding standards and best practices.
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.
Implement and refine rate conversion, filtering, correlation, windowing, decimation, interpolation, and other real-time signal processing techniques, ensuring data accuracy and usability.
Develop, debug, and optimize software on Linux.
Support all phases of software development, including requirements gathering, architecture design, testing, deployment, and maintenance towards timely, iterative releases.
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.
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.
Create project/technical documentation and ensure compliance with industry standards and best practices.
