Sr. Antenna Design Engineer

Galaxeye Space; Bengaluru; On-site; INR 3,500,000 - 5,500,000; Full time

Job summary

GalaxEye Space in Bengaluru is seeking a Senior Antenna Engineer to lead the design, analysis, and validation of antenna and array systems for a space-borne SAR mission. You will guide the project from concept through flight qualification, applying first-principles EM theory and array-factor insights beyond CST/HFSS simulations.

The role requires strong fundamentals in electromagnetics, polarization, scan, and beam-steering, with collaboration across RF, mechanical, thermal, and systems teams.

Qualifications

• Strong grounding in electromagnetic theory (Maxwell's equations) and antenna radiation theory.
• Ownership of antenna/array design for aerospace or high‑reliability RF systems.
• Ability to reason about array behaviour beyond simulations and mentor juniors.

Responsibilities

• Own end-to-end antenna and phased-array architecture for the SAR payload from radiating element to full aperture.
• Perform full-wave EM simulation and cross-check results with analytical models and measurements.
• Plan and support antenna range testing, calibration campaigns, and environmental qualification.
• Collaborate with RF, mechanical, thermal, and systems teams to ensure co-optimization.
• Mentor junior RF and antenna engineers and review designs for conceptual soundness.

Job description

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.

Location: Bengaluru

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.
• Strong fundamental grounding in electromagnetic theory (Maxwells equations, wave propagation, radiation theory) and classical antenna
