About this role
Location: Warsaw, on-site
Employment: Full-time
Industry: Miltech / Defense
Our client is looking for a hands-on engineer to own the physical build side of their radio-electronic devices - from prototype to working hardware. This is not a schematic-only role: you'll be at the bench soldering, assembling, and tuning RF modules yourself.
About the Role
You'll take RF/microwave devices and modules through the full development cycle — from concept to working prototype. That means building test setups, soldering and assembling boards, running lab measurements, tuning RF paths, and sourcing the components to make it all happen. You'll work closely with PCB designers and firmware engineers, but the hands-on hardware work is yours.
What You'll Do
Participate in the full development cycle of RF devices and modules - from idea to prototype
Assemble, solder, and tune experimental radio-electronic units
Run lab testing, take measurements, and tune RF paths to spec
Source, select, and procure RF components, connectors, and materials
Work closely with PCB designers and firmware engineers throughout the build
What We're Looking For
Technical degree in radio engineering, radiophysics, electronics, or telecommunications
4 + years developing, assembling, debugging, and testing RF/microwave electronic devices
Confident hands-on soldering and assembly skills - SMD/BGA components, chips, RF connectors, cable assemblies
Real experience with physical assembly, prototyping, breadboarding, and tuning RF blocks and modules
Fluent with lab equipment: VNAs, spectrum analyzers, oscilloscopes, signal generators, power meters
Able to measure and interpret path parameters - S-parameters, gain, noise figure, P1dB, VSWR, phase noise
Familiar with the RF component market (DigiKey, Mouser, Farnell, Arrow, etc.); can find alternates, read datasheets, and build a BOM independently
English (working communication)
