Principal Software Engineer

At RTX, the world's 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 market 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.

Join us and help shape the future of aerospace and defense. RTX BBN Technologies is an organization which values work/life balance and encourages lifelong learning of new technologies. For over 70 years, scientists and engineers in diverse disciplines at RTX BBN Technologies have collaborated to solve real‑world problems through research, exploration, development and prototyping. We challenge the status quo, pioneer new technologies, and create transformative solutions.

• Linux and VxWorks real‑time software development on a wide range of embedded multi‑threaded platforms
• Integrating with custom hardware
• Implementation of high‑performance embedded solutions
• Middleware
• Implementing control, detection, and tracking algorithms developed by the systems engineering team

The ideal candidate enjoys working in a multi‑disciplinary role and is comfortable adapting to and identifying new technologies as needed. This candidate would have eight or more years of experience in implementing and maintaining high performance software, as well as a solid understanding of computer architectures, networking, device drivers, analog and digital interfaces, with experience across multiple real‑time operating systems (RTOS).

A strong background in signal processing and performance optimization would also be highly sought after.

• Design, develop, implement, test, debug and integrate high performance embedded real‑time software within heterogeneous systems composed of multiple processor types and FPGAs, with external sensor and control interfaces for deployed DoD real‑time software systems hosted on embedded hardware
• Collaborate with a cross‑functional team testing your contributions and analyzing performance
• Integrate components you develop into a larger system in preparation for real world testing and deployment
• Teaching, coaching, and mentoring less experienced staff
• Contributing to proposals as well as preliminary and critical design reviews
• Travel required up to 15%

Involvement in the technical components of solving our customer’s most complex problems. Work with world‑class researchers and engineers who embrace innovation and challenge the status quo. Experience in a highly visible software development team, exposure to the Navy acquisition process, and opportunity to learn new technologies and gain new embedded development experiences.

• Typically requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 5 years of prior experience
• Active and transferable Secret U.S. Government Security Clearance is required on day one
• Experience including at least two of the following:
  Embedded C/C++ Software, High Performance Computer Systems, Embedded Real‑Time Sensors and Control Applications, Software Architecture Design and Implementation
