Senior RF & Radar Front-End Engineer – X-/W-Band Targeting Sensors

About Promethion Industries

Promethion Industries is a European defence technology company building autonomous supremacy systems for aerial and multi-domain operations. We design tightly integrated autonomy stacks in Europe to enable decisive autonomy for NATO-aligned forces, focusing on defensive and counter-system capabilities including anti-UAS and resilient autonomy under contested conditions. Alongside this, our team explores open code libraries and hardware platforms for robotics vision and perception A.I. powered by synthetic data, challenging corner paradigms to make autonomous robotics more accessible.

We are looking for a Senior RF & Radar Front-End Engineer — X-/W-Band Targeting Sensors to lead the rapid development of compact fixed-aperture radar front ends for airborne targeting and relative sensing applications.

Your mission with us

• Lead the rapid prototyping of compact X- and W-band radar front ends for airborne targeting applications.
• Develop and evaluate fixed-aperture / staring radar sensor architectures optimized for compact, SWaP-constrained platforms.
• Design and prototype dielectric lens-fed apertures, including 3D-manufactured dielectric lens concepts and compact antenna feeds.
• Develop practical Tx/Rx RF chains using commercial components and evaluation hardware before moving toward custom electronics.
• Work hands-on with antennas, waveguides, feeds, LNAs, PAs, filters, mixers, synthesizers, transceivers and RF interconnects.
• Evaluate the trade-offs between X-band and W-band for aperture size, angular resolution, integration effort, losses, range performance and manufacturability.
• Characterize RF performance through simulation, bench measurements and field testing.
• Own calibration and measurement procedures for RF front ends and complete sensor assemblies.
• Work closely with mechanical and systems engineers on packaging, thermal management, structural integration and lens geometry.
• Integrate the radar front end with embedded compute and downstream target-tracking / sensor-fusion systems.
• Move quickly from block diagram to physical prototype and from bench testing to airborne validation.
• Build the hardware foundation for subsequent custom RF, embedded-processing and radar-signal-processing development.

Your contribution to the team (required)

• Strong hands-on experience in microwave or mmWave RF engineering.
• Practical experience building and debugging RF front ends.
• Strong understanding of antennas, apertures and complete Tx/Rx signal chains.
• Experience with radar or RF sensing systems beyond simulation-only work.
• Hands-on experience with RF laboratory equipment including VNAs, spectrum analyzers, signal generators and power measurement.
• Strong understanding of gain, noise figure, dynamic range, losses, impedance matching and calibration.
• Experience integrating RF transceivers and commercial RF components into working prototypes.
• Ability to translate EM/RF concepts into manufacturable physical hardware.
• Strong experimental mindset and ability to diagnose unexpected RF behaviour.
• Comfortable working across RF, mechanical, embedded and software interfaces.
