Principal/Sr Flight Software Engineer

Sierra Space Careers: Dare to Dream

About the RoleDo you enjoy developing new products and services? Join us! Our Software Engineers work in an agile, collective environment. You will be using your skills and expertise to define, design, develop, test, certify and improve cutting-edge software products. 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 perform coding, debugging, testing, and troubleshooting of systems and software throughout our development process. Your technical duties involve the design and development of new software products throughout the product lifecycle.

Sierra Space’s Defense division focuses on the design, build, and operations of small satellites in support of commercial services and national security space.

As a Flight Software Engineer, your primary responsibility will be designing and developing flight software and algorithms solutions for 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, implementing and testing the design in a testbed prototype and subsequent delivery of the flight code. Along the way, you will 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. 

The Software Engineer participates in all portions of the software life cycle (concept development, requirements definition, design, development, testing, and deployment) of flight software to support ongoing and future small satellite programs. This individual must have a strong working knowledge of object-oriented design using C++ and must have a strong background in developing flight code on embedded processors.  The ideal candidate will have recent experience with at least one real-time operating system (such as VxWorks) and be familiar with both asymmetric and symmetric multiprocessing architectures.  The candidate must also be comfortable working in an Agile Scrum environment.
