## Position Summary We are seeking a talented engineer to join us in the design of Nex Generation RF Systems. The Sr Staff RF Engineer will significantly contribute to the design and development of hardware equipment to support antennas, phased array antennas, active electronic steerable phased array antennas, and associated distribution architectures for RADAR and other military systems. This includes lower-level requirement development, component selection, schematic creation, printed wiring board design, prototype testing and supporting transition to production of the hardware. This position also requires the communication, interpersonal, and business skills needed to be a member of a program team including communication to internal and external customers, and management of schedules and budgets, development of test plans, trade studies, and requirements documents. ## Key Responsibilities 1\. Defining and driving RF system architecture decisions, establishing technical roadmaps, and ensuring alignment with program and enterprise-level objectives 2\. EM Analysis

• Perform high‑frequency EM analysis using Ansys HFSS and/or CST Studio Suite. Import the 3‑D PCB stack‑up from the CAD tool, apply adaptive FEM meshing for resonant features (e.g. narrow‑width microstrip or SIW resonators) and FIT meshing in CST for broadband sweeps across multiple bands 3\. Technical Reviews
• Lead design reviews, first‑article inspections (FAI), critical design reviews (CDR), and preliminary design reviews (PDR); present findings to cross‑functional teams and program leadership 4\. Serve as a technical authority for RF design, analysis, and test across multiple programs, providing independent review and approval of critical technical artifacts 5\. Mentorship
• Coach mid‑level and junior RF PCB designers, providing technical guidance, layout "PCB layout review" checks, and RF layout skill development support 6\. Security & Compliance
• Maintain compliance with security protocols (need‑to‑know, classified data handling, secure workspaces) and ensure all design artifacts are stored in authorized classified repositories ## Standard Job Description Architects and designs Radio Frequency systems and circuitry.

Designs and develops RF circuitry used in high frequency and microwave applications, including receivers, transmitters, antennas, and frequency synthesizers. Responsible for hardware layout, component evaluation, prototype construction, and test. Prepares test methods and specifications; analyzes and tests RF hardware to verify performance characteristics. Provides inputs to Product Development for formal documentation and supports manufacturing during the deliverable assembly and test phase. In addition, develops RF System/Subsystem Architectures consisting of: antennas, transmitters, receivers, low noise amplifiers, high power amplifiers, RF conversion elements and transmission line equipment. Performs link analysis and optimization, including effects of propagation medium and possible interference sources. Develops and allocates RF system and subsystem functional and performance requirements. Identifies and tracks RF technical performance measurements (TPMs). Performs RF system/subsystem/component trade studies and CAIV analysis. Supports Life Cycle Costs, reliability, availability, and maintainability analysis. Proficient in AI prompting as it applies to this position and practice. ## Basic Qualifications 1.
