ullibJob purpose: /b Antenna passive RF/microwave design /lilibEmployment condition: /b Full-time, 40 hours per week. /liliCandidate must be eligible to work in the EU. /li /ulh3bCompany Description /b /h3pMetaSensing is an innovative Italian remote sensing company founded in 2008 with the aim of commercializing the new compact, high resolution radar mapping technology. /ppIn just a few years, MetaSensing has acquired numerous successful airborne radar campaigns completed at the Ka, Ku, X, C, S, L and P frequency bands, and developed drone and space-based radar systems for different applications. /ppToday MetaSensing is one of the unique companies in the world which offer cost effective airborne and space-based radar sensors and services both for commercial and security applications. /ppCombination of innovative technology and advanced processing techniques has made MetaSensing a fast growing, global company with projects in Europe, South-East Asia, Middle East, North and South America. /ph3bJob Duties /b /h3pYou will turn system requirements into validated RF hardware by combining a solid foundation in modern antenna theory and microwave engineering with hands-on skills in simulation, layout/prototyping, and lab characterization.

We value engineers who can interpret system metrics (gain, sensitivity, dynamic range, nonlinearity, spurious/harmonics) and drive iterative improvement through tight design-build-test loops. /ph3bKey Responsibilities and Tasks /b /h3ulliAntenna passive RF/microwave design (microstrip/patch antennas, slots, horns/reflectors, antenna arrays, power dividers/combiners, couplers, transitions across microstrip/stripline/coax/waveguide domains) /liliBuild 3D EM models and perform optimization in CST Studio Suite (preferred): boundary conditions, meshing strategy, ports, parameter sweeps, near-to-far transformations. /liliContribute to RF PCB implementation and review: stackups, controlled impedance routing, grounding, transitions, via strategies.

Coordinate with manufacturing/assembly partners to ensure DFM/DFT readiness and repeatable builds /liliCharacterize and manage linearity metrics: IP2/IP3, P1dB, gain compression, intermodulation products, spurious and harmonic content, NF.

Support selection/integration and validation of RF front-end components and modules (LNA/driver/PA/mixer/LO chain) /liliMeasurement and verification with VNA, spectrum analyzers, signal generators, and power meters to measure harmonics, two-tone IP2/IP3, P1dB / gain compression, spurious, intermodulation products and NF.

Support antenna pattern/gain/polarization validation (anechoic chamber or equivalent) /liliContribute to waveguide components and interfaces design: transitions, flanges/connectors, couplers, and waveguide-based filtering concepts.

Resonator-based structures: cavity/coaxial resonators, high-Q approaches, tolerance/temperature impacts /li /ulh3bRequired skills and qualifications /b /h3ulliStrong fundamentals in:ulliAntenna metrics (directivity, gain, efficiency, bandwidth, polarization, cross-pol) /liliArrays (array factor, grating lobes, sidelobe management, tapering) /liliTransmission lines, matching networks, and S-parameters /li /ul /liliPractical lab skills and measurement discipline; ability to troubleshoot discrepancies and close the loop between simulation and hardware /liliProficiency with CST Studio Suite (preferred); working knowledge of ADS/AWR and PCB tools (Altium/KiCad/OrCAD) is a plus /liliPreferably 3+ years in advanced technology, defense, radar, communications, or RF product development /li /ulh3bCommunication /b /h3ulliStrong communication skills required, including the ability to clearly express technical concepts in verbal and written forms across different management levels. /liliAbility to work in team.

Taste for international contacts. Manifest the flexibility needed to be integrated in the different stages of a project. /liliGood knowledge of the English language for the working environment /liliBSc is the baseline requirement /liliMSc/PhD is a strong plus - especially in antennas, electromagnetics, RF/microwave engineering, waveguides/resonators, radar/communications, or related domains /li /ul
