Sine Engineering builds the technology behind reliable drone autonomy — communications, navigation, and control that keep multi-drones coordinated at once. Over 200 UAV manufacturers rely on our systems, and our technology powers most of the interceptor operations active today. Through a dual-use platform, we support civilian innovation while helping democratic nations strengthen their technological edge.
Any drone, any scale, anywhere — resilient communication, navigation, and coordination built for the age of autonomy. Our products have already proven themselves in real combat conditions in Ukraine.
We are looking for a talented RF Engineer to participate in the development, testing, and evaluation of RF devices and systems. The position involves working with high-frequency measuring equipment, preparing test benches, analyzing measurement results and creating technical documentation.
Location: Lviv (on-site)
Schematic design of RF and mixed-signal electronic devices.
PCB layout design for high-frequency and mixed-signal systems.
Verification of designs through SPICE simulation, testing, and lab measurements.
Preparation and maintenance of technical documentation: schematics, BOMs, production files, and test reports.
Preparation and configuration of test benches for RF measurements.
Measurements of characteristics and parameters of radio frequency devices, modules and assemblies.
Initial processing of results, analysis of the data obtained, preparation of technical reports.
Cooperation with the development team to validate design and circuit solutions.
Higher technical education in the field of radio engineering, radio electronics or related areas.
Basic knowledge of high-frequency circuitry, analog and digital communication systems, signal processing methods.
Experience with RF measuring equipment: vector analyzers, spectrum analyzers, signal generators.
Skills in working with precision soldering equipment, including soldering SMD components (sizes 0402, 0201).
Proficiency in engineering CAD: KiCAD, Altium Designer.
Attention to detail, responsibility in work.
Knowledge of English at a level sufficient for reading and compiling technical documentation.
Knowledge of antenna theory, experience in measuring their characteristics.
Experience with automated measurement systems (e.g., using Python/Matlab to collect and process data).
Flexible working hours, 24 days of paid annual leave, and unlimited sick leave.
Health insurance (broad coverage), sports activities.
Learning support: external/internal training, English courses, and covered AI tools & software licenses.
Military service deferral (reservation) for eligible employees, plus support for veterans and their families.
A comfortable, safe workplace — ergonomic setups, on-site bomb shelter, modern equipment, and daily snacks.
A human-centric culture built on trust and ownership, where people care about each other and getting things done matters most.
