RF/ Antenna Engineer (office OR remote) in Kraków

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 & AVAILABILITY: POLAND (primary work location)

This is a remote-first role with no fixed office attendance requirement. However, due to the nature of some projects, occasional visits to the office may be necessary to access equipment, take measurements, or carry out other tasks requiring physical presence. Depending on the project, these activities may account for approximately 30–40% of the working time.

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-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

Good communication skills and B2+ level of English (daily communication with the team and clients)

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 and remote work opportunities

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

HiQo University- internal education and training programs

HiQo Coins - system of rewarding employees for extracurricular activities
