Design, simulate, and optimize antennas across multiple frequency bands (100 MHz to 10 GHz).
Perform electromagnetic simulations using industry-standard tools such as CST Microwave Studio.
Build prototypes, conduct measurements, and validate antenna performance in laboratory and field environments.
Collaborate closely with RF, hardware, and mechanical engineers to integrate antennas into compact device form factors.
Prepare technical documentation, test reports, and design guidelines for internal and external stakeholders.
Contribute to innovation initiatives and R&D projects focused on advanced antenna technologies and architectures.
Skills and Requirements
1+ years of experience in antenna design and RF engineering. We welcome candidates of all seniority levels.
Strong expertise in electromagnetic simulation and measurement techniques.
Hands-on experience with various antenna types, including log-periodic, patch, batwing, phased-array, and similar designs.
Solid understanding of RF and microwave design principles, including PCB integration.
Strong analytical, debugging, and problem-solving skills.
Nice to Have
Experience with advanced antenna technologies such as beamforming and MIMO systems.
Experience in RF circuit design and simulation.
Familiarity with device certification processes, including CE, FCC, and RED.
Experience with modern EDA tools such as Altium Designer or KiCad.
Experience using Azure DevOps, Jira, or similar project and requirements management tools.
Experience working in an international engineering environment.
What We Offer
Flexible working hours, 24 days of paid annual leave, and unlimited sick leave.
Comprehensive health insurance and sports activity support.
Learning and development support through external and internal training, English courses, and company-covered AI tools and software licenses.
Military service deferral (reservation) for eligible employees, plus support for veterans and their families.
