ph3About the job RF Antenna Engineer - First Technical Hire, PLANARIS /h3 /brpPLANARIS is building the antenna technology that will define how satellites communicate in the New Space era. We're looking for the engineer who will help shape that technology from the ground up. As our first technical hire, you'll work directly with our scientific founders, influence key architecture decisions, and grow with the company as we scale from lab validation (TRL 4) toward orbit. /p /brpBacked by foundational patents, 250 scientific publications, and an active pipeline with Europe's top space integrators, we're looking for a brilliant Fresh Graduate (MSc) or PhD ready to trade the lab bench for real, flight-ready hardware. /p /brpWe are replacing bulky reflectors and power-hungry phased arrays with our proprietary, software-defined thin-film "antenna skins." /p /brh3What You Will Do: /h3 /brul /brliSimulate Model: Design, optimize, and help define the technical roadmap for next-generation reflectarray/transmitarray unit cells using tools like CST, HFSS, or TICRA. /li /brliPrototype Test: Participate hands-on in the RF characterization, near-field/far-field antenna range measurements, and mechanical integration setups. /li /brliMission Tailoring: Collaborate on link budget and beam-forming optimization for real missions, from commercial LEO constellations and 5G-NTN (Direct-to-Device) to tactical defense applications. /li /brliIP Expansion: Contribute directly to patent filings, translating novel structural, material,



and electromagnetic designs into protected IP. /li /br /ul /brh3Who You Are: /h3 /brul /brliEducation: MSc or PhD in Telecommunications, Aerospace, or Electronic Engineering, specialization in RF, Antennas, Electromagnetics, or Satellite Communications. Both fresh graduates and recent PhDs are welcome; what matters most is technical depth and hands-on curiosity. /li /brliTechnical Skills: Familiarity with EM simulation software (HFSS, CST, etc.) and a solid foundation in microwave/antenna theory (space-fed arrays or metasurfaces is a strong asset). /li /brliMindset: A problem-solver with a startup hustle. You are passionate about SpaceTech, defense sovereignty, and breaking traditional hardware boundaries. /li /brliLanguages: Fluent in English and Spanish. /li /br /ul /brh3We Offer: /h3 /brul /brliDirect mentorship from globally recognized antenna scientists and seasoned deep-tech entrepreneurs. /li /brliCompetitive base salary aligned with early-stage deep-tech benchmarks in Spain. /li /brliReal ownership from day one, including equity allocation with standard vesting terms. /li /brliA front-row seat in a rapidly scaling New Space startup with an ITAR-free supply chain. /li /brliClear growth path as the company scales toward In-Orbit Demonstration (IOD) and beyond. /li /brliFlexible, hybrid/remote work environment, Spain. /li /br /ul /brpFlexible, hybrid/remote work environment, Spain. /p /p #J-18808-Ljbffr
