In this role, you will bridge the gap between high-level Software-Defined Radio (SDR) concepts and high-yield mass production. You will guide modular architectural layouts, define core interfaces for internal and external sensors, implement critical DFx methodologies, and mentor junior talent within an evolving, fast-paced technical landscape\nKey Responsibilities\n1. Architecture & System-Level Design\nArchitect modular, RF transceiver systems and define cascading link budgets (NF, Gain, IP3, P1dB) from antenna to converter.\n\nDesign advanced wideband SDR front-ends and direct RF sampling topologies tailored to defeat dynamic threats.\n\nEstablish Interface Control Documents (ICDs) and hardware abstraction standards to seamlessly integrate 3rd-party subsystems (Radar, EO/RF).\n\n2. Detailed HW Design, Simulation & Validation\nLead schematic capture, high-frequency/high-density PCB layout supervision, and component choices (PAs, LNAs, synthesis filters).\n\nPerform electromagnetic and circuit-level modeling (ADS, HFSS, or equivalent) to resolve structural EMI/EMC and co-site isolation issues.\n\nFormulate strict engineering Verification & Validation (V&V) plans, overseeing environmental and compliance certifications.\n\n3. DFx & Production Scale-Up\nChampion Design for Manufacturing/Assembly/Test (DFM/DFA/DFT) workflows to ensure stable, repeatable high-yield production loops.\n\nDefine line-calibration algorithms, built-in self-tests (BIST), and leverage Statistical Process Control (SPC) data to reduce production and field escalations.\n\n4. Leadership & Mentorship\nCollaborate across disciplines (Mechanical, Digital, Cyber-Software) to systematically resolve thermal, power, and high-speed noise friction points.\n\nAct as a primary technical mentor for junior engineers, implementing standard product lifecycle (PLC) gating and best practices\n\nRole Requirements\n Experience: 7+ years of hands-on professional RF/Microwave hardware design and architecture experience (Defense, Aerospace, or Telecom preferred).\nEducation: Bachelor's or Master's degree in Electrical Engineering, RF Engineering, or a highly related discipline.\nRadio Architecture: Deep knowledge of modern SDR structures, direct RF sampling frameworks, high-speed ADCs/DACs, and discrete active/passive components.\nProduction Track Record: Demonstrated success taking at least two multi-layered RF products through full PLC gates from initial concept into mass production.\n Tool Mastery: Proficiency with industry simulation suites (ADS, HFSS, CST) and standard schematic/layout platforms (Altium, Cadence, or equivalent).\n Lab Capabilities: Expertise with core diagnostic tools (Vector Network Analyzers, Spectrum/Signal Analyzers, digital signal generators, noise figure meters).\nPreferred Qualifications\nProven competency navigating complex co-site isolation and spectrum management parameters in highly congested environments.\nFamiliarity with RFI/EMI compliance standards (MIL-STD, CE, FCC) and mitigating failures early in layout.\nAn agile, structured mindset with an eagerness to introduce robust, proactive engineering workflows to a growing team.","description_format":"text","description_chars":3312,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Air
