We are seeking a motivated and skilled RF / Antenna Engineer to work on a wide range of client projects: design reviews, antenna development and integration, tuning, transmission line and filter work, near-field and EMC debugging, and pre-compliance measurements. The hardware is never the same twice, and the answer usually comes from combining simulation, measurement, and good engineering judgment.
You will work at the intersection of electromagnetism, PCB design, and mechanical integration - turning requirements into antennas and RF solutions that actually work in the finished product, and telling the client clearly what to change when they don't.
LOCATION: POLAND
Flexibility to work either from our Krakow/ Wroclaw offices or from a home office – the choice is up to you!
RESPONSIBILITIES:
Working on RF-related projects requiring review, troubleshooting, and improvements
Designing transmission lines, matching networks, and filters
Building prototypes and test fixtures; preparing samples for measurement
Measuring on a VNA and spectrum analyzer: S-parameters, impedance, power, harmonics, spurious emissions, and occupied bandwidth
Tuning antennas with discrete matching networks on bare PCBs and inside enclosures
Designing and modeling antennas and RF structures in EM solvers, running parametric sweeps and optimization
Probing boards with near-field probes to localize EMC interference sources and propose concrete fixes
Running, assisting, or consulting on conducted and radiated pre-compliance sweeps and assessing certification pass risk
Writing measurement reports, review findings, and recommendations
Contributing to internal measurement methods, fixtures, test setups, and report templates
Solid knowledge of RF and antenna fundamentals
Good understanding of electromagnetic waves and propagation
Good knowledge of analog and high-speed digital electronics
Solid experience with transmission lines, impedance matching, and confident use of the Smith chart
Hands-on experience with any full-3D EM simulation tool (HFSS, CST, openEMS, EMerge, or similar)
Practical and wide experience with a VNA and a spectrum analyzer
NICE TO HAVE:
Experience with full FCC / ETSI certification campaigns and accredited test labs
Experience with radiated measurements on bench or semi-anechoic/anechoic setups
Experience with EMC troubleshooting and debugging with near-field probes
Experience with PCB CAD tools (Altium, KiCad, or similar)
Knowledge of PCB materials and manufacturing tolerances (FR4 vs Rogers, over-etch, Dk spread)
Understanding of PCB stack-up choices, RF grounding, vias, discontinuities, and component placement
Programming and scripting skills (Python, MATLAB, C)
Good communication and teamwork with hardware and firmware engineers
WE OFFER YOU:
Available cooperation models: UoP or B2B
Office space or 100% remote – whichever suits you best!
Communication in English - only foreign customers, and international Teams
Simple structure and 'open door' way of communication
Full-time English teachers
Medical insurance for employees
