Say HI* to your career as

RF expert (m/f/d)

In Ditzingen#LI-HYBRID

InDitzingen you willencountersecurity 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 GermanArmed 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 systems detection range clutter suppression and Doppler performance.

Your missionas RF expert (m/f/d):

• RF architecture & system design
  • Define the front-end architecture and the overall frequency plan including spur and image analysis
  • Establish the RF link budget: cascaded noise figure sensitivity gain distribution compression and intermodulation and end-to-end dynamic range
  • Derive RF requirements from system-level radar parameters (range waveform PRF instrumented Doppler sub-clutter visibility)

• Streaming & data movement
  • Design zero-copy / DMA-based ingest paths from FPGA-based front-ends into GPU memory
  • Build deterministic real-time-capable streaming pipelines including buffering backpressure handling and precise time-stamping

• Transmit & receive chain design
  • Design the receive chain: LNA mixing/conversion stages IF/baseband filtering gain control (AGC) and receiver protection/limiting
  • Design the transmit chain: up-conversion driver and power-amplifier stages pulse modulation and T/R switching with sufficient transmitreceive isolation
  • Design the data-converter interface (ADC/DAC) including anti-alias and reconstruction filtering matching and clocking
• Frequency generation & coherence
  • Design the frequency synthesis for a fully coherent system
  • Optimize phase noise and timing/clock jitter as the key levers for MTI/Doppler improvement factor and sub-clutter visibility
• Layout integration & bring-up
  • Lead board bring-up and integration with antenna and digital front-end

We are looking forward to:

• Completed technical studies e.g. in computer science or electronical engineering

• Solid 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 intermodulation

• Frequency 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) advantageous

• Understanding of high-speed data converters and their RF interface (sampling clocking jitter) advantageous

• Familiarity with fundamentals of digital signal processing as it relates to the front-end (filtering sampling Doppler/MTI) advantageous

• Python/MATLAB for modeling validation and tooling advantageous

• Strong team and communication skills in a small interdisciplinary prototyping team

• Analytical and structured way of thinking and working

• Self-directed proactive working style with a high level of ownership

• Performance-driven engineering mindset paired with disciplined measurable optimization

• Pragmatic hands-on prototyping mindset willingness to iterate fast and learn from hardware

• Willingness to travel for integration and measurement campaigns (15%)

• Very good German and English skills
