RF Antenna Systems Engineer

Position: RF Antenna System Engineer Location: Harwell Campus, Oxford Satraka is on a mission to connect the unconnected and serve the underserved with its innovative, cutting-edge tracking- and multi-beam antenna technology, providing broadband internet connections anywhere, anytime via 4G/5G-based terrestrial network (TN) and satellite-based non-terrestrial network (NTN). Antenna is an exciting and challenging subject right at the core of all wireless telecommunication systems. This is particularly true in nascent, yet fast-growing high-data-rate broadband internet services, where both antenna performance, reliability and costs are put to the test. Based at Harwell Science and Innovation Campus - the UK's Space Cluster, Satraka enjoys a highly dynamic and exciting environment and access to a range of world-class facilities & expertise such as RAL Space, Science and Technology Facilities Council (STFC) and Satellite Applications Catapult. We are seeking a highly skilled and motivated RF Antenna System Engineer to join our dynamic engineering team. In this role, you will be responsible for the design, development, and testing of RF systems for a range of advanced tracking antennas. This includes design and hands-on work on various type of antennas, feed systems, filters, front-end components such as low noise blocks (LNBs) and block upconverters (BUCs), software defined radios, modems as well as related subjects such as link budget and radio wave propagations. You will collaborate with cross-functional teams across RF, embedded systems, mechanical, software coding and business development to deliver robust, optimized, and reliable user terminals and tracking antenna solutions. Main Duties Define system-level and sub-system-level requirements; perform performance analyses including link budgets, G/T, and EIRPDefine and qualify system components and interfaces, including telecom 4G/5G radios, satellite LNAs, and BUCsIntegrate and test RF systems within tracking antennas and user terminalsOptimize system-level Input/Output performance (IOPs) for real-time data communication and controlCollaborate with hardware and software teams to ensure overall system performance, reliability, and integrationConduct lab and field testing of RF and embedded systems using RF test equipment (e.g., VNAs, spectrum analyzers, signal generators)Work closely with antenna and mechanical engineering teams to develop solutions for network acquisition, tracking, antenna control, and multi-network managementLead the full product development lifecycle: from system requirements and software architecture to embedded system design, integration, testing, optimization, and deliveryPrepare detailed technical documentation, including design specifications, performance analysis, integration procedures, and test reportsSupport Business Development with technical expertise during proposal preparation and customer engagementsInterpret and negotiate technical requirements with customers; define feasible solutions and perform trade-off analysesManage work schedules, resources, and technical risks to ensure high-quality, on-time, and on-budget deliveryCoordinate closely with Project Managers to ensure successful project completion Skills and Experience Degree in Physics, Electronic Engineering, Computer Engineering, or a related fieldStrong knowledge of RF, radio, and communication systemsHands-on experience designing RF systems with LNAs, BUCs, filters, and duplexersProficient in link budget calculations and system performance analysis (G/T, EIRP, SNR, etc.)Practical experience with satellite systems, 4G/5G radios, tracking antennas, and network integrationProficient with RF simulation tools such as CST, HFSS Familiar with EMC/EMI compliance and relevant regulatory standardsUnderstanding of Software Defined Radio (SDR) platforms like GNU Radio or USRPKnowledge of digital signal processing (DSP) techniques for modulation, filtering, and encodingExperinces in phased array and electronically steered antenna (ESA) systemsSkilled in full product lifecycle development from requirements to integration, testing, and deliveryConfident in system-level debugging and root cause analysis across hardware and softwareAble to write clear technical documentation and explain complex ideas to both technical and non-technical audiencesStrong problem-solving skills focused on practical, innovative solutionsExcellent written and verbal communication skills in English Personal Attributes Strong interpersonal and communication skillsSelf-motivated and driven to meet objectivesEffective team player; able to work independently or collaboratively as requiredAble to work within defined timescales and meet programme milestonesCapable of managing multiple projects simultaneouslyPassionate about technical challenges, problem solving, and practical innovationWilling to learn, share knowledge, and go the extra mile for the teamBuilds effective working relationships at all levelsExcellent at planning and organising workload across projects to meet deadlinesQuality-focused with strong attention to detail Benefits: Work with cutting-edge technology and innovation-driven projects Competitive salary, holiday and pension contribution Opportunities for fast career advancement and professional progression If you are interested in working with Satraka, then please email your CV and a covering letter to info@Satraka.com with the job title you’re applying for in the Subject line of the email.
