Responsibilities
Lead the end-to-end design of antenna systems for spaceborne and/or ground-based applications
Independently design antennas and phased array systems using ANSYS HFSS, from initial concept through final layout
Define antenna architectures supporting beamforming, beam steering, and multi-beam operation
Design and optimize phased array antennas, including element design, array layout, feed networks, and radiation pattern control
Perform detailed full-wave EM simulations in HFSS to evaluate gain, efficiency, bandwidth, polarization, sidelobe levels, and mutual coupling
Optimize antenna designs to meet system-level requirements such as coverage, link budget, and interference mitigation
Work closely with RF, mechanical, and manufacturing teams to transition HFSS designs into physical hardware
Support antenna prototyping, integration, and validation testing
Define and execute antenna test plans, including chamber, range, and over-the-air (OTA) measurements
Analyze measurement results and correlate test data with HFSS simulation results
Collaborate closely with Systems Engineers, RF Engineers, Payload Engineers, and Network Design teams to ensure antenna designs meet end-to-end system requirements
Provide technical mentorship and design guidance to junior engineers
Help establish antenna design standards, workflows, and best practices across the organization
