Senior Antenna Design Engineer Job Arlington area,Texas USA,Engineering

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

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 deliveryassociated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 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-Space’s 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.

On-site in California or Texas. Some travel between sites may be required.

What you will do:

Antenna Architecture and Design
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
Simulation, Analysis, and Optimization
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
Hardware Development and Testing
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
Cross-Functional Collaboration and Leadership
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

Technical Requirements:

Antenna and RF Fundamentals
Strong background in antenna theory, electromagnetics, and RF engineering
Deep experience with phased array antennas and beamforming techniques
Simulation and Design Tools
Expert-level proficiency with ANSYS HFSS for antenna design and simulation
Experience with additional EM tools (CST, FEKO) is a plus
Proficiency with MATLAB and/or Python for analysis and automation
Hardware and Measurement
Hands-on experience with antenna prototyping, integration, and testing
Experience with phased array antenna calibration techniques and procedures
Familiarity with RF test equipment and antenna measurement techniques, including near-field and far-field chamber testing

What you bring to this role:

Master’s or PhD in Electrical Engineering or a related field, with a focus on Antennas,…
