Software Engineer

Johns Hopkins Applied Physics Laboratory (APL) seeks a Software Engineer to build mission-critical systems for national security, space exploration, and health. You will design, implement, and test secure, scalable software in a collaborative, research-driven environment, working alongside scientists and engineers to solve real-world problems. Responsibilities include developing production-quality code, integrating with complex systems, and contributing to prototypes and tools. APL supports advanced training, graduate education, and professional growth while fostering an inclusive, ethical, and intellectually curious culture. Design, develop, test, and deploy software solutions for national security, space, and health missions. Collaborate with scientists, engineers, and analysts to translate mission needs into robust software systems. Implement secure, reliable, and scalable code following modern software engineering best practices. Participate in code reviews, integration, and troubleshooting across complex systems. Contribute to research prototypes and transition them into production-ready capabilities. Document designs, interfaces, and test approaches to support maintainability and knowledge sharing.
