Draper is looking for a highly skilled principal software engineer to join the Mission Software Architectures and Applications group. The Principal Flight Software Engineer develops high performance solutions for resource constrained targets. They design and develop resilient, fault tolerant, real-time, highly reliable software solutions in the application domains of undersea, terrestrial, air, hypersonics and space. The Engineer is well-versed in the full mission-critical software development life cycle, from architecture conceptualization, requirements analysis, design and documentation through development, testing and release. They collaborate across multiple interdisciplinary teams to plan, build and test new functionality. They work on developing and debugging embedded software as well as executing software and system-level tests in various engineering environments, including complex software-in-the-loop simulations and real-time hardware-in-the-loop environments. The candidate will be expected to follow and push for continuous improvement of software development best practices on complex projects. They will also be expected to provide mentorship to more junior software engineers.
