At GalaxEye Space, we are pioneering the next generation of Earth observation solutions with our cutting-edge satellite technology. As a fast-growing space-tech startup, our mission is to revolutionize the way we gather, process, and deliver geospatial intelligence. In this journey,

We are seeking a Senior Antenna Engineer to lead the design, analysis, and validation of antenna and array systems for a space-borne SAR mission, from concept through flight qualification. The role requires strong fundamentals in antenna theory and electro magnetics , with the ability to independently reason about array behaviour beyond CST/HFSS simulations. The candidate should have expertise in **array factor, mutual coupling, grating lobes, polarisation, beam steering, and RFthermalmechanical interactions , while working closely with RF, mechanical, thermal, and systems teams.

Join us to become a part of an agile, high-impact team working at the forefront of space innovation.

Key Responsibilities

- Own the end-to-end antenna and phased-array architecture for the SAR payload, from radiating element and full aperture definition.
- Apply first-principles electromagnetic and antenna theory, array factor synthesis, mutual coupling, active element pattern, scan blindness, grating lobe conditions, and aperture illumination/tapering to guide design decisions rather than relying on simulation tools alone.
- Design and analyse microstrip, waveguide, or other radiating element topologies suited to the space borne radar frequency band, polarisation scheme (single/dual/quad-pol), and power-handling requirements.
- Perform full-wave electromagnetic simulation and analysis using CST Studio Suite, HFSS, or equivalent tools,



and independently interpret and cross-check results against analytical models and measurement data.
- Analyse and mitigate mutual coupling, surface waves, edge diffraction, and thermal/mechanical distortion effects on array pattern performance.
- Define and support beamforming network requirements in coordination with the RF and hybrid TTD/phase-shifter beamforming teams, including phase/amplitude calibration and error budget allocation.
- Support development of the Transmit/Receive Module (TRM) and panel-level RF interfaces, ensuring antenna and front-end RF performance are co-optimized.
- Plan and support antenna range testing, near-field/far-field pattern measurements, calibration campaigns, and environmental qualification (vibration, thermal-vacuum) of antenna hardware.
- Correlate simulation models against measured antenna and array data, and update analyses and margins accordingly.
- Prepare antenna design reports, analysis and verification documentation, interface control documents, and test procedures.
- Support integration, in-orbit commissioning, anomaly investigation, and mission operations from an antenna/RF performance perspective.
- Mentor junior RF and antenna engineers, and review their designs and analyses for conceptual soundness, not just simulated results.

Requirements

- Masters degree/ Ph.D in Electronics/Communication Engineering, Electrical Engineering, Antenna/RF Engineering, or a related field.
- 7+ years of experience in antenna and phased-array engineering, with demonstrated ownership of antenna design for aerospace, spacecraft, radar, or other high-reliability RF systems.
- Solid fundamental grounding in electromagnetic theory (Maxwells equations, wave propagation, radiation theory) and classical antenna
