Kapta Space develops metasurface electronically-steered radar antenna arrays for LEO SAR, InSAR and GMTI to deliver persistent geospatial imagery, cm-scale deformation maps and ground-target tracking for commercial and defense.
Kapta Space, a VC-funded early-stage startup in Seattle, WA, is breaking new ground in Geospatial Intelligence. Our technology centers around a proven, scalable electronically-steered radar for sophisticated spaceborne applications such as earth observation using synthetic aperture radar (SAR) techniques, as well as enabling advanced defense missions such as target tracking on the ground and in the air. Kapta is seeking a Principal RF/Microwave Engineer to design, develop, integrate, and qualify RF and microwave hardware for our electronically-steered spaceborne radar systems. This engineer will translate radar-level requirements into high-performance, flight-ready hardware spanning transmit and receive signal chains, RF distribution networks, filtering, switching, amplification, frequency conversion, calibration, and interfaces to high-speed digital electronics. As a critical contributor to payload development, this role operates within a highly multidisciplinary environment requiring engineering trade studies and design decisions across RF performance, DC power, thermal management, reliability, manufacturability, environmental robustness, and overall payload performance. This is a hands-on principal-level individual contributor role with substantial technical authority across design, test, qualification, and production. The ideal candidate combines deep RF/microwave theory with practical design and laboratory experience and has a track record of taking complex RF hardware from first principles through flight-ready implementation. This engineer will lead critical design decisions and reviews, exercise strong technical judgment, and work independently across a fast-paced, multi-disciplinary team. Experience with coherent multi-channel receivers, transmitters, phased arrays, radar, or space/defense hardware is especially valuable.
