Job Title

About the CompanyGalaxEye aims to shape the future of Satellite Image Acquisition, providing the most meaningful datasets (SyncFused OptoSAR), thus helping businesses and governments make data-driven decisions based on insights from satellite imagery. We design and build advanced remote-sensing satellites with sophisticated payloads such as Synthetic Aperture Radar (SAR) and High Resolution MSI which can generate SyncFused Images.About the RoleWe are looking for a Senior Antenna Systems Engineer with deep expertise in Active Phased Array Antenna hardware and RF system engineering. The candidate will lead the design, development, and qualification of a flight-ready radar payload featuring distributed T/R modules, beam-forming networks, and array-level design. This role requires hands-on experience with high-frequency microwave electronics, antenna array integration, manufacturing oversight, and environmental qualification.ResponsibilitiesDefine architecture for a space-qualified Active Phased Array radar, including array topology, T/R module, aperture size, beam steering capability, and coverage requirementsSpecify radar performance requirements: bandwidth, PRF, radiated power, beam agility, side-lobe levels, effective aperture, and thermal headroomLead design, testing, and characterization of high-frequency T/R modules, including LNAs, PAs, phase shifters, attenuators, limiters, and isolatorsWork with packaging and layout teams on MMIC integration, microstrip/stripline routing, and thermal management of high-density RF boardsDefine and validate calibration strategies to ensure array coherence (gain/phase uniformity, drift compensation, amplitude tapering)Coordinate control electronics development (biasing, phase control logic, routing, and timing distribution)Support array mechanical design for deployment, panel alignment, grounding, and RF isolationDevelop comprehensive test plans for array-level characterization: beam pattern testing, steering performance, phase coherence, element matching, and mutual couplingUse VNAs, phased array measurement systems, anechoic chamber testing, and near-field scannersManage interface definition to spacecraft subsystems (EPS, OBC, TM/TC, structural mounting, harnessing, and power conditioning)Lead design reviews, including RF architecture reviews, array build reviews, and test readiness reviews (SRR / PDR / CDR)Prepare documentation such as ICDs, technical specifications, bill of materials, calibration procedures, and test reportsMentor junior engineers and interns in RF, phased array, and microwave test procedures QualificationsMust HavesHands-on experience designing, validating and de-bugging Active Phased Array systems (preferably Ka/X/S/C-band), beamforming networks, etc.Hands-on experience in working with Beamformers, FEM's, TRM's, HPA, LNA, Phase Shifters, etc.Proficiency with RF/microwave test equipment and anechoic chamber array measurementKnowledge of RF system fundamentals including S-parameters, impedance matching, noise figure, linearity, harmonic control, and signal routing for dense RF systemsGood to HavesExperience with space grade qualification standards (ECSS, MIL-STD, ISRO, NASA)Familiarity with radiation effects, thermal conduction in vacuum, and space-level reliability engineeringEM simulation experience using HFSS, CST, FEKO, AWR, or equivalent toolsKnowledge of MMIC design, GaN power amplifiers, and advanced antenna materials (RF laminates, metalized substrates, radomes, etc.) Required SkillsSystems thinker with strong analytical and debugging skills.Inclusive leader who can mentor a diverse, distributed team. Someone who can bring in the culture of ownership and responsibility to the team while by giving them technical and creative freedom with necessary guidance.Clear, concise communicator who builds trust across hardware and software.Ready to learn new concepts, stay up-to-date with the state-of-the-art in the field and implement them.Ability to work within deadlines and dynamic projects.
