About the role

Key responsibilities & impact
  • Provide technical leadership on advanced Low Observable antennas, conformal apertures, ultra-wideband phased arrays, and passive RF structures
  • Develop technical solutions for radar, electronic warfare, electronic attack, electronic support measures, communications, geolocation, and direction-finding applications
  • Lead design teams through architecture trades and detailed electromagnetic analysis
  • Model antenna performance, RCS signatures, aperture interactions, and airframe-coupled electromagnetic effects using full-wave computational EM tools
  • Develop antenna and Low Observable design concepts addressing gain, VSWR, bandwidth, field of view, scan performance, polarization purity, structural constraints, and signature objectives
  • Guide antenna and RF performance verification and validation, including gain/pattern testing, polarization, insertion loss, and RCS measurement campaigns
  • Collaborate with systems engineering to define RF and RCS requirements and support architecture-level trade studies
  • Translate system-level needs into antenna-level requirements, specifications, and verification plans
  • Fabricate prototypes, debug hardware, optimize builds, and support manufacturing and qualification
  • Mentor engineers in advanced EM modeling, Low Observable techniques, prototyping, and range testing
  • Present technical findings to leadership, customers, and program stakeholders
  • Contribute to technical proposals, concept generation, and competitive strategy
  • Execute creative and independent technical work on high-visibility programs
  • Maintain relationships with internal and external customers and represent the organization on difficult technical issues

Requirements

What you’ll need
