RF Expert (m/f/d)

Location: Stuttgart, GermanyWe say HI*Thales in Germany is part of an internationally leading technology group in the defence and security, aerospace as well as cyber security and digital identity markets. Say HI* – to your career asRF expert (m/f/d) In Ditzingen #LI-HYBRIDIn Ditzingen, you will encounter security solutions for monitoring and safeguarding borders and for border controls, protection of civil and military facilities and tactical communication. This is the right place for you if you want to work with us on practical highly mobile radars for ground and coastal monitoring or night vision goggles and multifunctional heat imaging equipment. Join the Thales expert team for radar, optronic vision systems for armoured military vehicles or for protecting the field camps of the German Armed Forces. We are happy to have you on board!  As RF / Front-End Engineer you own the analog heart of our radar sensor: you architect and design the complete RF transmit and receive front-end – from the antenna interface through low-noise reception, coherent frequency generation and up-/down-conversion to the data-converter interface that feeds the digital processing chain. You are responsible for the signal integrity, phase coherence and dynamic range that ultimately define the system's detection range, clutter suppression and Doppler performance.Your mission as RF expert (m/f/d):RF architecture & system designDefine the front-end architecture and the overall frequency plan, including spur and image analysisEstablish the RF link budget: cascaded noise figure, sensitivity, gain distribution, compression and intermodulation, and end-to-end dynamic rangeDerive RF requirements from system-level radar parameters (range, waveform, PRF, instrumented Doppler, sub-clutter visibility)Streaming & data movementDesign zero-copy / DMA-based ingest paths from FPGA-based front-ends into GPU memoryBuild deterministic, real-time-capable streaming pipelines including buffering, backpressure handling and precise time-stampingTransmit & receive chain designDesign the receive chain: LNA, mixing/conversion stages, IF/baseband filtering, gain control (AGC) and receiver protection/limitingDesign the transmit chain: up-conversion, driver and power-amplifier stages, pulse modulation and T/R switching with sufficient transmit–receive isolationDesign the data-converter interface (ADC/DAC) including anti-alias and reconstruction filtering, matching and clockingFrequency generation & coherenceDesign the frequency synthesis for a fully coherent systemOptimize phase noise and timing/clock jitter as the key levers for MTI/Doppler improvement factor and sub-clutter visibilityLayout, integration & bring-upLead board bring-up and integration with antenna and digital front-endWe are looking forward to:Completed technical studies, e.g. in computer science or electronical engineeringSolid hands-on RF/microwave front-end design experience (LNA, mixer, PA, filter, conversion stages)Strong command of RF system design: link budget, cascaded noise figure, dynamic range, compression and intermodulationFrequency synthesis and low-phase-noise design (LO generation/distribution, coherent clocking)Experience with RF measurement and characterization (VNA, spectrum/signal/phase-noise analyzers, noise-figure measurement)Experience with radar front-ends and coherent / pulse-Doppler systems advantageous RF/mixed-signal PCB design and EM/signal-integrity awareness; RF simulation tools (e.g. ADS, AWR, EM solvers) advantageousUnderstanding of high-speed data converters and their RF interface (sampling, clocking, jitter) advantageousFamiliarity with fundamentals of digital signal processing as it relates to the front-end (filtering, sampling, Doppler/MTI) advantageousPython/MATLAB for modeling, validation and tooling advantageousStrong team and communication skills in a small, interdisciplinary prototyping teamAnalytical and structured way of thinking and workingSelf-directed, proactive working style with a high level of ownershipPerformance-driven engineering mindset paired with disciplined, measurable optimizationPragmatic, hands-on prototyping mindset – willingness to iterate fast and learn from hardwareWillingness to travel for integration and measurement campaigns (~15%)Very good German and English skillsThe Group invests more than 4,5 billion per year in Research & Development in key areas, particularly for critical environments, such as Artificial Intelligence, cybersecurity, quantum and cloud technologies. In 2025, the Group generated sales of 22.1 billion.For our more than 85,000 employees in 65 countries we open up visionary perspectives, realise individual career paths and enable creative freedom. This is achieved with courage, versatility and the firm intention to make the demanding challenges of our time safer and more inclusive. With our sustainable value-focused management we support diversity actively.Say HI* – Your journey to usAt times of change our international teams are ready to meet the complexity of today with the industry-leading technologies of tomorrow.
