Senior Antenna Design Engineer

E-Space•Saratoga, CA

3d•$150,000 - $200,000•Onsite

About The Position

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. Weâre intentional, weâre unapologetically curious and weâre 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life. As a Senior Antenna Design Engineer, you will own the end-to-end design, simulation, and validation of advanced antenna systems for E-Spaceâs LEO satellite constellation and ground infrastructure. You are expected to independently design antennas using full-wave electromagnetic simulation tools, with HFSS as a primary design environment, and drive designs from concept through hardware validation.

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 antenna trade studies considering performance, size, weight, power, thermal, and manufacturability constraints
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
Use MATLAB or Python for post-processing, parametric sweeps, and design automation
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
