ARQUIMEA, we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors. Our areas of activity are Aerospace, Defense & Security, Big Science, Biotechnology and Fintech. Lead the RF system engineering activities for space communication payloads, taking technical ownership of the RF subsystem, ensuring compliance with system requirements and coordination across all relevant disciplines, suppliers, customers, and stakeholders. Act as technical responsible for the RF subsystem, coordinating its design, development, integration, verification and qualification throughout the project lifecycle. Define RF subsystem architectures from concept level, translating mission and customer needs into feasible RF solutions, including architecture trade-offs, frequency plans, RF chains, technology selection, interfaces and preliminary performance budgets. Define, develop and maintain RF subsystem architectures throughout the project lifecycle, including frequency plans, RF chains, interfaces, redundancy concepts, operational modes and associated technical budgets. Perform and review RF system analyses and budgets, including link budgets, gain, noise figure, output power, losses, linearity, spurious emissions, filtering and frequency conversion. Coordinate RF engineering activities and ensure alignment between internal teams, suppliers and project needs. Manage technical interfaces with other spacecraft disciplines, including thermal, mechanical, electrical/electronics, digital/FPGA, EMC, AIT and systems engineering. Coordinate technically with external suppliers and subcontractors, including requirements flow-down, technical follow-up, design reviews, technical clarifications and acceptance of deliverables.



Define and coordinate RF verification and test activities, including unit, subsystem and payload-level testing. Review test plans, procedures, test results, anomalies and non-conformances, ensuring proper requirement verification and closure. Support and participate in AIT and environmental test campaigns, including RF performance verification before and after environmental testing. Prepare and participate in project milestones and reviews such as SRR, PDR, CDR, TRR, QR and AR. Degree in Telecommunications Engineering, Electrical/Electronics Engineering, or a related technical field. ~+5 years of experience in RF/microwave engineering, preferably including space, defence, satellite communications or other high-reliability systems. Training / specific knowledge required in: Strong background in RF and microwave systems engineering, preferably for space, defence or high-reliability applications. Knowledge of key RF parameters and analyses: gain, noise figure, P1dB, IP3, phase noise, spurious, harmonics, isolation, return loss and VSWR. Experience with RF test equipment such as VNAs, spectrum/signal analyzers, signal generators and power meters. Ability to coordinate multidisciplinary technical activities and manage interfaces with mechanical, thermal, electronics, digital and system engineering teams. Experience interacting technically with customers, suppliers and subcontractors. Ability to review supplier documentation, technical proposals, test reports and compliance matrices. Strong technical documentation and communication skills in English. Nice-to-have training / specific knowledge: Knowledge of ECSS standards and space project lifecycle. Knowledge of EMC/EMI and its interaction with RF subsystem performance. Familiarity with RF payload calibration and end-to-end performance verification.
