Englewood, Colorado

Do you have an eye for detail and a passion for developing innovation solutions? Join our team! As a Guidance, Navigation and Control Engineer, you will be using your skills and expertise to design and test algorithms, flight software, related hardware, design tools, simulations, and more for various aerospace vehicles. These cover a very wide range from advanced mission payloads and electronic systems through highly integrated aircraft to orbital and space exploration systems. You'll explore complex GN&C algorithms and systems to assess performance of vehicle flight qualities and capabilities. Your technical duties involve the design, development, evaluation, and test of new products and processes throughout the product lifecycle.

At SNC’s Space Systems Group (SSG) we are not only the creator of the Dream Chaser® spacecraft, but also the designer and manufacturer of rocket engines and components, systems that sustain life in deep space, as well as systems and satellites that improve life here on Earth. The work of our Space Systems team not only supports the U.S. government (including NASA), but also commercial customers and international organizations. Learn more about SSG

As a GN&C Engineer at SNC, you will focus on the design and development of flight and simulation algorithms solutions for tests and spacecraft missions for both civilian and DoD applications.  These designs stem from understanding, analyzing and evaluating satellite and constellation capabilities, mission concepts, and system requirements. Your work will ensure we meet customer requirements by making data-driven decisions in architecting, planning, building and testing the design in a testbed prototype and subsequent delivery of the end product. Along the way, you will build tools and contribute to analyses of various architectures that include space vehicles, satellites, sensors, communications, and ground infrastructure; evolving or creating new approaches based on analysis results. You will also contribute to evaluating the mission effectiveness of the candidate approaches, balancing mission objectives against factors such as development and lifecycle costs.  

This candidate will have experience with all portions of the software life cycle (concept development, requirements definition, design, development, testing, and deployment).  Additionally, the successful candidate will have experience doing GN&C-related analysis such as performance analysis, multi-sensor fusion and estimation/filtering, sensor processing and/or other advanced GN&C analyses.  This individual has a strong working knowledge of Matlab and Simulink and experience with code development.  Object-oriented design using the C and C++ languages is a plus, as is having experience in deploying and testing flight code on embedded processors.
