Drive Flex Architecture: Drive the full lifecycle of flex interconnect systems across product generations, from early-stage conceptualization through verification, qualification, and high-volume manufacturing. RF & Mechanical Optimization: Maintain high signal integrity and RF performance while ensuring long-term mechanical reliability, durability, and thermal performance. Vendor Management: Work directly with external partners and suppliers to push the boundaries of flex design and manufacturing capabilities. Translate complex RF, mechanical, and system-level specs into unambiguous technical requirements for vendors, secure clear partner commitments. Timeline Execution: Ownership of supplier development schedules, ensuring critical components are delivered on time without compromising quality or yield. Drive internal project execution, setting schedule milestones, tracking deliverables, and keeping the team accountable to QuantWare's roadmap. Direct Line Leadership: Lead, mentor, and grow an engineering team dedicated to flex interconnect development and RF integration. Requirements

4+ years of hands-on experience in RF engineering, signal integrity, or high-frequency interconnect design (e.g., flex circuits, rigid-flex, micro-coaxial interfaces). Deep hands-on experience with standard RF simulation software (HFSS, CST, ADS, or equivalent) and RF measurement equipment (VNAs, Spectrum Analysers, TDR). Proven Track Record: Demonstrated success leading hardware or R&D engineering projects from initial concept through verification to volume production. Vendor Co-Development: Direct experience managing external vendors, JDM partners, or component suppliers to deliver complex custom electro-mechanical parts.
