Fullerton Hiring Software Engineering Intern

Are you ready to explore aerospace and defense? Do you want to learn from and collaborate with some of the greatest minds in the industry? At RTX, internships, co-ops and full-time careers offer a strong foundation to work on complex problems, grow your skills and help create a safer, more connected world.

What You Will Do

You will help build software that turns complex sensor data into information people can understand and act on. Teams develop software for radar and command-and-control systems, with work spanning backend services, data processing, and full-stack web applications.

As a Software Engineering Intern, you will work alongside experienced engineers to solve practical problems and contribute to software used in demanding environments. Depending on your project, you may develop a service, build an interactive interface, improve system performance, or automate testing.

Your responsibilities may include:

• Build useful software: Design, code, test, integrate, and document new capabilities and improvements to existing applications.
• Connect data to decisions: Contribute to software that processes information, connects services, or presents complex data through web interfaces and visualizations.
• Solve a defined engineering challenge: Translate requirements into an implementation, explore technical tradeoffs, and deliver work with clear scope and expectations.
• Collaborate across disciplines: Work with software and systems engineers to understand how your contributions fit into the larger system.
• Learn through feedback: Take part in design discussions, code reviews, and demonstrations to build your engineering judgment and communication skills.
• Develop professional engineering habits: Use version control, automated testing, debugging, and established development processes to produce reliable, maintainable software.

What You Will Learn

• Modern software tools and practices: Gain hands-on experience with development tools, automated testing, and workflows used to build reliable software.
• How complex systems fit together: Learn how software architecture connects sensors, backend services, and user interfaces in radar and command-and-control systems.
• Engineering tradeoffs: Understand how teams balance performance, reliability, security, and maintainability, and how those decisions support broader technical strategy.
• Emerging technologies: Explore advances in software development, radar, and command-and-control systems, and evaluate how they could improve your project.

Preferred Qualifications

RTX welcomes students with different technical interests and backgrounds. Experience in any of the following areas is helpful:

• Software design fundamentals, including object-oriented programming, data structures, and algorithms.
• Web application development, including user interfaces, backend services, REST APIs, or databases.
• Systems programming, concurrent programming, networking, or applications that process streaming data.
• Data visualization, statistical or numerical methods, or an interest in sensor and radar applications.
• Development tools and practices such as Git, Linux, automated testing, or continuous integration.
• Projects that show curiosity, initiative, and the ability to turn an idea into working software.
• Clear communication, effective teamwork, and a willingness to ask questions, learn from feedback, and work through unfamiliar problems.

What We Offer

RTX values Trust, Respect, Accountability, Collaboration, and Innovation. Relocation eligible.

Candidates may be asked to attend select interview steps in person at an RTX office, whether the role is onsite, hybrid or remote. This role is onsite and U.S. citizenship is required.
