RF 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 technologies, and our solutions power many of the interceptor operations active today.

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. Our products have already proven their effectiveness in real combat conditions in Ukraine.

We are looking for a talented RF Engineer to contribute to the development, testing, and evaluation of RF devices and systems. This role involves working with high-frequency measurement equipment, preparing test benches, analyzing measurement results, and creating technical documentation.

Location: Lviv (on-site)

Responsibilities

• Design RF and mixed-signal electronic circuits and schematics.

• Develop PCB layouts for high-frequency and mixed-signal systems.

• Verify designs through SPICE simulations, testing, and laboratory measurements.

• Prepare and maintain technical documentation, including schematics, BOMs, production files, and test reports.

• Set up and configure test benches for RF measurements.

• Measure and evaluate the characteristics and performance of RF devices, modules, and assemblies.

• Analyze measurement data and prepare technical reports based on the results.

• Collaborate closely with the engineering team to validate design concepts and circuit solutions.

Requirements

• Bachelor's or Master's degree in Radio Engineering, Electronics, Telecommunications, or a related technical field.

• Basic understanding of RF circuit design, analog and digital communication systems, and signal processing techniques.

• Hands-on experience with RF measurement equipment such as vector network analyzers, spectrum analyzers, and signal generators.

• Experience using precision soldering equipment, including soldering SMD components (0402 and 0201 packages).

• Proficiency with engineering CAD tools such as KiCad or Altium Designer.

• Strong attention to detail and a high level of responsibility.

• English proficiency sufficient to read and prepare technical documentation.

Nice to Have

• Knowledge of antenna theory and experience measuring antenna characteristics.

• Experience with automated measurement systems and data collection/processing tools such as Python or MATLAB.

What We Offer

• Flexible working hours, 24 days of paid annual leave, and unlimited sick leave.

• Comprehensive health insurance and support for sports activities.

• Learning and development opportunities through internal and external training, English courses, and company-funded 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 human-centric culture built on trust and ownership, where people care about one another and strive to deliver meaningful results.
