Antenna Design Engineer

We are seeking an Antenna Engineer to design, simulate, and validate advanced antenna systems for both on-orbit and ground-based platforms. In this role, you will be responsible for developing antennas critical to communications and radar systems across our space and terrestrial infrastructure.

You will collaborate closely with RF, mechanical, systems, and firmware engineers to create antennas that meet the performance, reliability, and packaging constraints of space-based missions. You’ll play a key role in bridging simulation and hardware, translating electromagnetic theory into high-performance, flight-ready systems.

• Collaborate with systems engineers to evaluate link budgets and overall system performance
• Design, simulate, and optimize antennas including patch antennas, microstrip arrays, and phase arrays
• Prototype and test antenna systems in lab and field environments, including range and anechoic chamber testing
• Develop manufacturing and test procedures in collaboration with production teams
• Perform full EM simulations using tools such as HFSS, CST, and ADS
• Support bring-up, integration, and verification of antennas in both development and flight environments
• Define antenna requirements and interface with spacecraft and payload subsystems to ensure integration feasibility

Our next-generation sensing technology will directly enable breakthroughs in climate science, autonomy, defense, and disaster response.

Candidates can expect 2–4 weeks of interviews including Zoom and on-site technical discussions.

• Ability to work in a fast-paced, iterative design environment
• Excellent teamwork and communication skills
• Familiarity with integration challenges including mechanical packaging, thermal constraints, and EMC/EMI
• 3+ years of industry or research experience in antenna or RF systems engineering
• Exposure to software-defined radios (SDRs) and digital beamforming techniques
• Experience designing and deploying antennas for LEO satellites or aerospace applications
• US citizen or permanent resident (green card)
• Knowledge of RF materials and manufacturing constraints for space-based systems
• Experience with antenna design, simulation, and measurement tools (e.g., HFSS, CST, ADS, MATLAB)
• Proficiency in laboratory test equipment: vector network analyzers (VNAs), spectrum analyzers, signal generators, etc
• Experience with RF system calibration and over-the-air (OTA) testing
• Knowledge of transmission line theory, impedance matching, and RF system design
• Bachelor’s degree in Electrical Engineering, Physics, or a related field
• Hands-on experience with phased array design and beamforming networks
• Master’s or Ph.D. in Electrical Engineering or related discipline
• To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State
