Antenna Engineer

About Sine Engineering

Sine Engineering builds the technology behind reliable drone autonomy, including communication, navigation, and control systems that enable coordinated multi-drone operations at scale. More than 200 UAV manufacturers rely on our technology, and our solutions power many of today’s active interceptor operations.

Through our dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological advantage.

Any Drone. Any Scale. Anywhere.

We build resilient communication, navigation, and coordination systems for the age of autonomy.

The Role

We are looking for an Antenna Design Engineer to join our growing engineering team. In this role, you will be responsible for designing, simulating, testing, and optimizing antenna systems for advanced autonomous platforms and communication solutions.

Responsibilities

• 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.

• A comfortable and safe workplace featuring ergonomic workstations, an on-site bomb shelter, modern equipment, and daily snacks.

• A people-first culture built on trust, ownership, and collaboration, where individuals genuinely care about one another and the impact of their work.
