Umbra is an American space technology company delivering advanced systems, from sensors to spacecraft, that empower customers worldwide with unmatched access to critical information from space. Our mission is simple and ambitious: redefine space—for people, systems, and missions in every domain. Umbra’s ecosystem operates through three business units: Remote Sensing (the data), Space Systems (the components), and Mission Solutions (the platforms). Together, our teams develop capabilities that deliver persistent access, resilient performance, and mission-ready solutions, advancing U.S. space leadership while keeping the world safe and informed.  About the Team Mission Solutions – The Platforms  Mission Solutions builds on Umbra’s expertise in remote sensing and spacecraft operations to engineer platforms purpose-built for U.S. and allied defense and intelligence missions. Whether it’s a custom payload, a full-stack spacecraft, or the infrastructure behind an entire constellation, our team delivers secure, resilient systems tailored to exacting requirements and built on timelines that match the urgency of the mission.    If you want to work on cutting-edge space technology that’s redefining what’s possible in space platforms, you belong here at Umbra.  About the Job We are actively searching for an accomplished RF Microwave Design Engineer who possesses deep understanding and substantial experience in various facets of antenna design. The ideal candidate will have specialized knowledge in key areas such as antenna feed systems, Orthomode Transducers, waveguide components, circulators, and other essential passive microwave hardware. This position is crucial, as it emphasizes the complete process involved in the design and analysis of high-performance passive RF structures tailored for precision antenna and RF front-end applications. The successful engineer will engage in innovative projects that require meticulous attention to detail and a comprehensive approach to ensure optimal performance in demanding RF environments. Our aim is to hire this position to work in our Arlington, VA office, or Reston, VA office (coming soon). This opportunity is contingent upon award of a federal government contract. Key Responsibilities Design and analyze antennas and antenna feed systems including feed horns, waveguide feeds, and polarization networks. Design, optimize, and validate orthomode transducers with high isolation, low loss, and broadband performance. Develop waveguide components such as transitions, bends, twists, couplers, filters, power dividers, and circulators. Perform passive RF and antenna analysis including impedance matching, isolation, insertion loss, and polarization. Conduct full-wave EM simulations of passive and antenna structures using 3D EM tools. Perform tolerance, thermal, and mechanical sensitivity analyses for precision passive hardware. Support fabrication, inspection, and RF testing of passive components, circulators, and antenna assemblies. Measure and analyze S-parameters, isolation, return loss, insertion loss, and antenna radiation characteristics. Collaborate with mechanical, systems, and integration teams to ensure RF performance, robustness, and manufacturability. Generate detailed design documentation, drawings, and verification/test reports. Required Qualifications Bachelor’s degree in Electrical Engineering, Applied Physics, or related field. 5-8+ years of professional experience in antenna and passive RF/microwave design. Strong foundation in antenna theory, waveguide theory, ferrite and passive microwave device theory. Demonstrated experience designing and building antennas, OMTs, waveguide-based components, and circulators. Proficiency with 3D EM simulation tools (HFSS, TICRA, CST, FEKO, or equivalent). Hands-on experience with RF and antenna measurement techniques. Desired Qualifications Masters degree in Electrical Engineering, Applied Physics, or related field. 12+ years of professional experience in antenna and passive RF/microwave design. Experience with multi-band, dual-polarized, or wideband antenna systems. Knowledge of horn, reflector, array, or feed network architectures. Familiarity with ferrite materials, magnetic biasing, and non-reciprocal device behavior. Experience with spaceborne, airborne, or ground-based antenna and RF front-end systems. Understanding of environmental qualification and high-reliability passive RF design. Active Security Clearance
