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 ENGINEER (STARSHIELD)Starshield leverages SpaceX's Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads. As a Sr. RF engineer on the Starshield team, you will be working on advanced development programs in support of US National Security. You will work with a team of fellow 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.RESPONSIBILITIESDrive program-level decisions on RF system designsResearch novel solutions for unique large-scale satellite RF systemsWork in close collaboration with hardware, FPGA, DSP, and software engineers to design and validate RF systemsResponsible for development and full life cycle support of RF hardware spanning PCBA board testing and defect detection, full functional testing of an assembled unit, and resolving on-orbit vehicle anomaliesCreate electromagnetic simulation models of hardware (antennas, filters, PCB layout) to design and evaluate performanceModify electrical schematics and mechanical drawings for flight applications as they relate to reliability and manufacturabilityBASIC QUALIFICATIONS:Bachelor's degree in computer engineering, or electrical engineering5+ years of experience RF engineeringExperience with modeling/analysis tools/software such as HFSS, CST, ADS, MATLAB, C/C++, and/or PythonExperience with RF test equipment such as VNA, spectrum analyzer, etc.Experience creating and maintaining link budgets and analysis related to communications or remote sensing systemsPREFERRED SKILLS AND EXPERIENCE:Graduate degree in electrical engineering with emphasis in microwave/RF engineering5+ years of professional experience in a relevant fieldExperience designing RF systems including radio astronomy, SIGINT, ELINT, radar, or wireless communicationsExperience modeling RF and channel impairments such as multipath, phase noise, group delay, fading and nonlinear distortionExperience with basic principles of antenna theoryExperience with software-defined radios and frameworks, such as GNU RadioAbility and willingness to obtain a Top Secret clearanceADDITIONAL REQUIREMENTS:An active clearance may provide the opportunity for you to work on sensitive SpaceX missions; if so, you will be subject to pre-employment drug and random drug and alcohol testingMust be willing to work extended hours and weekends as neededCOMPENSATION AND BENEFITS:Pay range:RF Engineer/Senior: $160,000.00 - $220,000.00/per yearYour actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan.
