Job Title: Chief Antenna Design Engineer
Job Code: 42608
Job Location: Rockwall, TX
Job Schedule: 9/80 (Every other Friday Off)
Job Description:
L3Harris is seeking a Chief Antenna Design Engineer to serve as a technical subject matter expert in the design of ultrawideband antenna and electronically scanned array (ESA) systems across various lifecycle phases for our Advanced Aperture Solutions (AAS) group. The Chief Antenna Design Engineer will be part of a multi-disciplined engineering team working on diverse antenna development projects. As a Chief Antenna Design Engineer, you will be directly supporting proposal efforts to generate new business, mentor younger peers, lead timely program execution, develop state-of-the-art antenna designs, and ensure antenna systems designs meet or exceed customer requirements. The role is for an individual who is open to additional learning and would relish the opportunity to immerse themselves in both project work and research and development activities.
The Advanced Aperture Solutions (AAS) group is quick reaction capability (QRC) aperture solutions business based in Rockwall, TX. AAS is responsible for the design and development of high-gain antenna systems for military airborne, maritime, and ground platforms. Our team has state-of-the-art design tools validated with real hardware prototypes including CST Design Studio Antenna Modeling Software, Circuit Board design software, MATLAB software, SolidWorks software, and a PCB Laser that produces multiple same-day iterations of antenna designs. We ultimately provide critical ISR capabilities to fight and win in the SIGINT operating environment.
Essential Functions:
- Serve as technical authority for complex antenna and RF/Microwave development programs including research, detailed design, and analysis for airborne, maritime, and ground systems.
- Guide the execution of technical design review briefings.
- Assess and report on technical project status, risks, and issues.
- Mentor and guide junior engineers on antenna development to ensure designs meet customer requirements
- Lead business development activities including planning, customer visits, technical briefings, and customer demonstrations.
- Generate accurate estimates for NRE and recurring costs.
- Serve as main technical point of contact with customers on technical and contractual matters, ensuring satisfaction and business growth
Qualifications:
- Bachelor’s degree in electrical, mechanical, or systems engineering with 12 years of prior relevant experience. Graduate degree and a minimum of 10 years of prior related experience. In lieu of a degree, a minimum of 16 years of prior related experience.
- Position requires the ability to obtain and maintain a DoD Secret Security Clearance
- Experience with design and analysis of antenna performance (gain, bandwidth, polarization, directivity, efficiency, etc.), RF Link Budgets and cascade analysis (gain, noise figure, linearity, noise power, etc.), S-parameters, matching networks, filtering (bandwidth, types,implementations, etc.).
- Antenna design experience for electromagnetics in the RF spectrum, including VHF, UHF, and microwave applications in the L, S, C, X, Ku, Ka, and V bands.
- Experience with antenna element design including horns, dipoles, patch, PIFAs, loop, slot, helical, fractal, Vivaldi, Biconical, Log-periodic, Yagi, etc.
- Experience with antenna simulation and analysis tools including CST, HFSS, SystemVue, Advanced Design System (ADS), MATLAB, and other ECAD design tools.
Preferred Additional Skills:
- Phased array design experience preferred.
- Antenna Range measurement techniques utilizing Planar Near Field Scanners, Spherical Near Field Scanners, Compact Ranges, Far Field Ranges, etc.
- Advanced user of antenna and RF lab equipment (Vector Network Analyzers, Spectrum Analyzers, Signal Generators, Noise Figure Meters, Power Sensors, etc).
- An understanding of programming languages (MATLAB, C/C++,LabVIEW, Qt, Python).
- Experience with wiring/block diagrams, mechanical drawings, and PCB schematic/layout drawings.
- Familiarity with direction finding (DF) systems, and digital beamforming.
- Ability to work both independently and within a team environment.
