RF Engineer - Electronic Warfare

About Us

STARK is a defence technology company redefining how autonomous and electronic warfare systems are deployed across modern battlefields. We design, develop, and manufacture high-performance unmanned and EW systems that are software-defined, mass-scalable, and operationally decisive. Our mission is to strengthen the technological edge of European and NATO forces through responsible innovation and uncompromising engineering excellence.

• RF Architecture:
  
  Deep understanding of transceiver architectures (Superhet, Zero-IF) and signal conditioning.

• Simulation Tools:
  
  Proficiency with electromagnetic simulation software (e.g., CST Studio Suite, HFSS, FEKO) and circuit simulation tools (e.g., Keysight ADS, AWR Microwave Office).

• Component Selection:
  
  Experience selecting discrete RF components (filters, couplers, circulators, switches) and designing matching networks.

• Layout Expertise:
  
  Proven expertise in RF PCB design layout techniques, preferably in Altium Designer, including mitigation of parasitic effects.

• Measurement:
  
  Hands-on proficiency with RF measurement techniques (S-parameters, Noise Figure, P1dB, IP3, etc.).

• Mindset:
  
  Ability to work with precision, discipline, and a strong security mindset suited for defense applications.

You will design and deliver high-performance hardware for next-generation electronic warfare systems that operate in the most demanding and contested environments.

• RF Chain Architecture:
  
  Design and implement high-performance RF up and down converter chains (superheterodyne, direct conversion) connecting the digital domain (ADC/DAC) to the antenna.

• Front-End Design:
  
  Develop robust RF Front-Ends (RFE), including Low Noise Amplifiers (LNA), Power Amplifiers (PA), mixers, filters, and local oscillators.

• Antenna Engineering:
  
  Simulate, design, and validate custom antenna elements and arrays optimized for size, weight, and power (SWaP) constraints on unmanned platforms.

• System Design:
  
  Conduct installed performance analysis (CST/HFSS) to optimize antenna placement, accounting for platform shadowing and coupling effects.

• PCB & Layout:
  
  Execute precision RF PCB layout (impedance control, layer stack-up management, signal integrity) using Altium Designer.

• Link Budgeting:
  
  Perform detailed system-level analysis, including cascade analysis (Gain, NF, IP3) and link budget calculations to define component specifications.
