Antenna Design Engineer

Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world. We’re launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth - updated in real time - enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence.We design and build our satellites end-to-end, producing the world’s most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they’re needed most.About the JobAs an Antenna Design Engineer, you will design, simulate, and validate the radiating structures and arrays used in Array’s spaceborne radar payloads. Your work will involve developing antennas with high power density, precise pattern control, and stable performance across the environmental and packaging constraints of small satellites. You will take designs from concept through EM analysis, prototyping, and qualification, working closely with RF, mechanical, thermal, and systems engineers. The antennas you develop will directly influence Array’s transmit power, imaging resolution, calibration stability, and overall radar system capability.As part of our quickly growing engineering team, you will play a critical role in the design of the world’s most advanced radar satellite constellation—one that will significantly improve humanity’s ability to rapidly and comprehensively understand our changing planet.ResponsibilitiesDesign, simulate, and optimize antennas including patch antennas, microstrip arrays, and phase arraysDefine antenna requirements and interface with spacecraft and payload subsystems to ensure integration feasibilityPerform full EM simulations using tools such as HFSS, CST, and ADSPrototype and test antenna systems in lab and field environments, including range and anechoic chamber testingSupport bring-up, integration, and verification of antennas in both development and flight environmentsCollaborate with systems engineers to evaluate link budgets and overall system performanceDevelop manufacturing and test procedures in collaboration with production teamsBasic QualificationsBachelor’s degree in Electrical Engineering, Physics, or a related field3+ years of industry or research experience in antenna or RF systems engineeringExperience with antenna design, simulation, and measurement tools (e.g., HFSS, CST, ADS, MATLAB)Knowledge of transmission line theory, impedance matching, and RF system designProficiency in laboratory test equipment: vector network analyzers (VNAs), spectrum analyzers, signal generators, etcExcellent teamwork and communication skillsAbility to work in a fast-paced, iterative design environmentUS citizen or permanent resident (green card)Preferred Skills & ExperienceMaster’s or Ph.D. in Electrical Engineering or related disciplineExperience designing and deploying antennas for LEO satellites or aerospace applicationsHands-on experience with phased array design and beamforming networksFamiliarity with integration challenges including mechanical packaging, thermal constraints, and EMC/EMIKnowledge of RF materials and manufacturing constraints for space-based systemsExperience with RF system calibration and over-the-air (OTA) testingExposure to software-defined radios (SDRs) and digital beamforming techniques ITAR RequirementsTo conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State Equal Opportunity EmployerArray Labs is an Equal Opportunity Employer.
