RF / Antenna Engineer (Poland)

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 REQUIREMENTS 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-
