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. ANTENNA 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 senior antenna engineer on the Starshield team, you will be working on advanced development programs in support of U.S. National Security. SpaceX is looking for antenna engineers with experience in small antenna design, phased array and reflector antenna systems, and/or antenna test and design validation. 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:Design of advanced antenna and feed systems in support of next generation products including phased array and reflector productsFabricate and characterize prototypes of antennas, feed systems and RF front endsContribute to development of software and testing of digital beamforming systems to demonstrate full phased array functionalityProvide phased array expertise to set specifications and debug problems covering satellite phased array productsLead or support integration of antennas to spacecraft and other systemsAnalyze in-the-field operational RF performance data of units and investigate methods to improve performance and debug issuesBASIC QUALIFICATIONS:Bachelor's degree in computer engineering, electrical engineering5+ years of research or development experience in the areas of RF and antennas (internship and thesis work are acceptable)3+ years of experience using one of the 3D EM simulation tools such as CST, HFSS, FEKO, EMPro, TICRA, or XFDTDExperience with basic RF concepts such as impedance matching, linear and aperture antennas, smith chart, power handling metrics (IIP2, IMD), microwave network analysis, RF filter designPREFERRED SKILLS AND EXPERIENCE:Master's degree or PhD in electrical engineering with some research/thesis work on RF or antennas5+ years of professional experience in a relevant fieldExperience with RF systems including SIGINT, ELINT, radar, or communications1+ years of programming experience in Python, C#, C++, or MATLABExperience designing RF systems including radio astronomy, SIGINT, ELINT, radar, or wireless communicationsFamiliar with antenna measurement techniques and tools such as anechoic/reverb chambers, near field EM measurementsFamiliar with one of the mainstream RF circuit simulation tools: AWR, ADS, GenesysFamiliar with antenna prototyping tools and techniquesAbility to work in a fast paced, autonomously driven, and demanding startup atmosphereExcellent communication skills both written and verbalPassion for advancing the commercial and National Security space industryAbility 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:Antenna 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, educat
