RF & Antenna Senior Design Engineer

The RF Antenna Senior Engineer is responsible for design, development, integration, and validation of RF, microwave, and antenna subsystems for Aerospace Defence platforms. The role requires strong hands-on design capability, ownership of assigned subsystems, and close collaboration with system, mechanical, and EMI/EMC teams.

; Key Responsibilities
Antenna Design Integration
Design and optimize antennas including:
Wideband and multiband antennas
Array and sub-array antennas
Radar, EW, Satcom, GPS, IFF, and data link antennas
Perform antenna placement and integration studies on platforms
Analyze coupling, isolation, and radiation pattern distortion
Support radome and RF-transparent structure evaluation

; RF Microwave Design
Design and analyze RF subsystems:
LNAs, PAs, filters, switches, couplers
T/R modules, beamforming networks
Perform RF chain analysis (gain, NF, IP3, P1dB, spurious)
Support schematic, layout review, and design validation

; Simulation Analysis
Perform EM simulation using HFSS, CST, FEKO
RF circuit simulation using ADS / AWR
Correlate simulation and measurement results
Conduct trade-off studies considering SWaP-C constraints

; Measurement Validation
Carry out antenna and RF testing:
VNA-based S-parameter measurements
Anechoic chamber measurements (gain, pattern, polarization)
RF performance testing (linearity, harmonics, spurs)
Support EMI/EMC, environmental, and qualification tests

; Aerospace Defence Compliance
Support compliance to MIL-STD, DO-160, DEF-STAN requirements
Prepare technical documents, test procedures, and reports
Participate in design reviews (PDR, CDR, TRR)

; Collaboration Execution
Work closely with system engineering, mechanical, thermal, and EMI/EMC teams
Support manufacturing, integration, and field issue resolution
Interface with customers and internal stakeholders for technical clarifications

; Required Skills Qualifications
