WHO ARE WE? Sateliot is a Barcelona-based Startup in the New Space sector, becoming the first satellite telecommunications operator that will provide global and continuous connectivity to all the elements that will make up the massive Internet of Things (IoT) universe under the 5G protocol. In order to do so, Sateliot is launching a constellation of last generation nanosatellites, located at low altitude that act as mobile towers. Sateliot is the perfect complement for large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not arrive. YOUR MISSION Sateliot is seeking an experienced Principal Antenna Product Engineer to lead the end-to-end development of an advanced antenna array for space applications. The successful candidate will take full ownership of the product lifecycle—from concept definition through design, simulation, prototyping, fabrication, testing, qualification, and flight readiness. This role requires deep expertise in antenna engineering for the space environment, including materials selection, lightweight and semi-rigid structures, and deployable antenna systems. The ideal candidate combines strong analytical rigor with first-principles thinking, and a pragmatic, goal-oriented approach focused on delivering flight-ready hardware within program constraints. Antenna design must be carried out in tight coordination with mechanical and thermal constraints, ensuring structural integrity, thermal stability, and manufacturability from the earliest design phases. The candidate will work closely with a senior mechanical engineer to ensure seamless RF-structural integration and optimized system performance. YOUR MAIN FUNCTIONS Technical Leadership & Product Ownership • Lead the architectural definition and technical roadmap of advanced antenna arrays for space applications., • Own the antenna system from concept to design for manufacture, qualification, testing and flight readiness., • Translate mission and system requirements into robust antenna design solutions., • Apply first-principles thinking to challenge assumptions and drive optimal, physics-based solutions., • Design high-performance antenna arrays (e.g., phased arrays, reflectarrays, patch arrays, deployable architectures)., • Perform full-wave electromagnetic simulations (CST, HFSS, FEKO or equivalent)., • Design antennas considering:, • Mechanical constraints (stiffness, launch loads, vibration, deployment reliability), • Thermal constraints (thermal gradients, expansion, cycling, distortion effects), • Mass optimization and structural integrity, • Manufacturability and assembly constraints, • Optimize radiation performance, efficiency, bandwidth, polarization, and thermal stability. Select and qualify materials considering: • Radiation tolerance, • Thermal cycling, • Outgassing (ECSS/NASA compliance), • Vacuum compatibility, • Lead the development of lightweight, semi-rigid antenna structures., • Contribute to or drive deployable antenna concepts and structural integration strategies., • Collaborate closely with the senior mechanical engineer to co-design RF and structural elements from early concept stages., • Oversee prototype development, including PCB-based RF structures, waveguide assemblies, and hybrid solutions., • Define fabrication tolerances, inspection criteria, and manufacturing workflows., • Ensure the design is optimized for repeatability, scalability, and production efficiency., • Interface with suppliers and manufacturing partners., • Define and execute RF validation campaigns (anechoic chamber, near-field/far-field measurements)., • Support environmental qualification (vibration, thermal vacuum, shock, radiation)., • Correlate EM simulations with structural and thermal behaviour., • Analyse test data rigorously and implement corrective design improvements., • Deliver test requirements and test reports., • Work closely with the senior mechanical engineer to ensure fully integrated RF-mechanical-thermal co-design., • Interface with systems, thermal, manufacturing, and mission engineering teams., • Support system integration and mission readiness reviews. REQUIREMENTS • Master’s or PhD in Electrical Engineering, Electromagnetics, RF Engineering, or related field., • 8+ years of experience in antenna design, • Proven experience delivering antenna systems from concept through qualification., • Strong understanding of space environmental constraints and compliant materials., • Experience with lightweight, semi-rigid, and/or deployable antenna structures., • Demonstrated ability to design antennas considering mechanical, thermal, and manufacturing constraints., • Expertise in electromagnetic simulation tools (HFSS, CST, FEKO or similar)., • Hands-on experience with antenna measurement and RF validation., • Attitude of the person:, • Need to have a “can do attitude”. Think outside the box and be able to push boundaries of physics., • Task oriented focused to close out actions ASAP., • Focused on time to market. NICE TO HAVE Preferred Qualification • Antenna design for space qualified systems, • Experience with phased arrays and beam-steering architectures., • Experience in LEO/MEO/GEO satellite missions., • Experience in S-band, L-band, Ka-band, or other satellite communication bands., • First-principles thinker with strong electromagnetic intuition., • Pragmatic and goal-oriented, capable of delivering robust solutions under program constraints., • Strong awareness of mechanical, thermal, and manufacturing realities., • End-to-end product ownership mindset., • Analytical and systematic problem-solving capability., • Cross-disciplinary collaboration skills., • Hands-on engineering attitude with attention to detail nd quality., • Clear technical communication and leadership abilities.
