We are looking for an RFSystems Engineer to design, integrate, characterize and improve the analog subsystems behind these systems.\nYour focus will span two key areas:\nLow-power RFreceive systems: filtering, amplification, signal conditioning, and integration with antennas and antenna arrays.\n\nHigh-power RFtransmit systems: power amplification, impedance matching, transmission lines, protection systems, and integration with antennas and antenna arrays.\n\nYour primary responsibility is the end-to-end analog RFsubsystem: you own its design and performance, and dive into individual components whenever required to improve the whole. You will have the freedom and responsibility to investigate problems deeply and turn engineering insight into measurable improvements in real systems.\nRFproblems rarely exist in isolation: antenna impedance affects the power amplifier, amplifier nonlinearities affect signal quality, and receiver characteristics interact with algorithms. You will develop design choices iteratively, moving from physical understanding and equations to models or simulations, then experiments, measurements and validation. Real system data will help you uncover effects that models miss and turn the results into system improvements.\nYou will work closely with system, algorithm, digital hardware, software and test engineers, translating system objectives into RFrequirements and measurement results into engineering decisions. The team brings deep experience across these disciplines, with support from specialist teams across Optiver. We move quickly, debate ideas openly regardless of who proposed them, and treat every result as a team result.\nWhat you'll do\n\nOwn the design, integration, characterization and performance of the analog RFreceive and transmit chains.\n\nWork with high-power transmit hardware, including power amplifiers, combiners, couplers, transmission lines and protection systems. Characterize gain, efficiency, linearity, harmonics, thermal behavior and load-mismatch tolerance.\n\nDesign and optimize impedance-matching and tuning solutions for changing antenna loads, balancing bandwidth, power handling, efficiency and reflected power.\n\nDevelop and integrate low-power receive chains, including LNAs, filters, switches and matching networks.\n\nWork with antennas and antenna arrays: impedance, bandwidth, radiation performance, feed systems, phasing and mutual coupling. Simulate antennas and antenna arrays with electromagnetic simulation tools such as NEC, FEKO, CST or HFSS, and validate simulations against measurements.\n\nCombine simulation, analytical modeling and measurement in Python to identify dominant system limitations, and work with system, algorithm and modeling engineers to investigate trade-offs and validate improvements across link budgets, cascaded gain and noise, nonlinear effects and array behavior.\n\nSpecify requirements toward suppliers: translate system objectives into clear specifications, find and evaluate antenna manufacturers and RFequipment vendors, and manage supplier engagements from first contact through quotation, delivery and acceptance testing.\n\nDefine and execute test strategies at component, subsystem and integration level, covering test setups, acceptance criteria, calibration and measurement uncertainty\n\nWho you are\nBS or higher in Electrical Engineering, RF/Microwave Engineering, Applied Physics or a related discipline, with minimum 3 years of hands-on experience with RF hardware or RF systems.\nStrong foundation in analog RF: you think naturally in terms of S-parameters, matching and cascaded gain and noise, and you understand how antenna impedance and load mismatch affect the performance of the whole system.\nGood understanding of low-noise receiver design (noise figure, sensitivity, dynamic range) and of antennas and antenna arrays (radiation patterns, phasing, mutual coupling).\nStrong measurement skills with VNAs, spectrum/signal analyzers, oscilloscopes, signal generators and RF power meters, and the ability to design meaningful, repeatable measurement setups.\nAnalytical mindset: you are able to describe physical RF behavior with equations, simplified models and numerical simulations, and correlate those models with measurements.\nSolid foundation in Python for analysis, modeling and measurement automation, and fundamentals of digital signal processing (sampling, filtering, spectral analysis).\nGood communication and project management skills or a clear willingness to develop them: you can write unambiguous requirements and specifications, coordinate with external suppliers, and drive engagements to completion.\nComfortable owning open-ended engineering problems from first investigation through design, experimentation and validation, and communicating trade-offs across disciplines\nNice to have\nHands-on experience with high-power RFhardware, including power amplifiers.\n\nExperience designing, modeling antennas and antenna arrays.\n\nExperience with RFmeasurement automation.\n\nNo prior trading or financial experience is needed - our onboarding program will kick-start your career at Optiver and support you in gaining all the relevant knowledge about our business.\nWho we are\nAt Optiver, our mission is to constantly improve the market by injecting liquidity, providing accurate pricing, increasing transparency and acting as a stabilizing force no matter the market conditions.
