Sr. RF Software Engineer (Starlink)

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.SR. RF SOFTWARE ENGINEER (STARLINK)Starlink believes in providing fast, reliable internet to serve populations with little or no connectivity. We design, build, launch, and operate the world's largest constellation of satellites, enabling us to operate a global internet network unbounded by traditional ground infrastructure limitations. Starlink also designs, builds, and delivers high-volume consumer hardware that allows users to connect to these satellites within minutes of unboxing, as well as our advanced gateways that we deploy regionally throughout the world. The root of SpaceX’s success so far lies in our mission to keep all engineering and production in-house, which enables a tight feedback loop, nimble decision-making, and speedy deliverables. With millions of daily users worldwide already online, Starlink is truly a game-changer and levels the playing field for those who were previously unconnected.As an RF software engineer in the Starlink program, you will work with a team of RF engineers, DSP engineers, software engineers, hardware engineers and end users to design and build RF capabilities for proliferated communications and remote sensing in low earth orbit. You will work in a highly collaborative and fast-paced environment, where we are exploring unsolved problems and applying the SpaceX mindset of iterating rapidly to go from design and demo to operational capability at lightning pace.RESPONSIBILITIES:Drive program-level decisions on RF system designsResearch novel solutions for unique large-scale satellite RF systemsDesign, build, validate, and automate RF test benches for full characterization of custom RF designs, often involving vector network analyzers (VNA), vector signal generators (VSG), vector signal analyzers (VSA), spectrum analyzers, load pulls, RF power meters, high-speed oscilloscopes, and other common lab equipmentDesign and build modular, scalable RF test infrastructure and test automation sequences in Python and C++ to support design validation, qualification, and productionWork in close collaboration with hardware, FPGA, DSP, and software engineers to design and validate RF systemsCreate electromagnetic simulation models of hardware to design and evaluate performanceBASIC QUALIFICATIONS:Bachelor’s degree in electrical engineering or other engineering discipline5+ years of professional development experience in C/C++ or PythonExperience with radio test equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, and network analyzersExperience with antennas or communication systemsPREFERRED SKILLS AND EXPERIENCE:Master's degree in electrical engineering or other engineering disciplineExperience with testing both active and passive RF devices such as filters, amplifiers, mixers, and upconverters/downconvertersExperience with common RF concepts such as gain, linearity, P1dB, ACLR, EVM, PAE, S-parameters, and input/output matchingExperience with software design principles, software architecture, design patterns, and unit/integration testing methodologyExperience with environmental test methodologies and equipment such as thermal chambers and temperature forcing systemsExperience in troubleshooting interactions between software and hardware, such as network devices and lab instrumentationExperience using Windows and Linux operating systems Experience with configuration management and version control softwareADDITIONAL REQUIREMENTS:Ability to work extended hours and weekends as neededITAR REQUIREMENTS:To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
