Sine Engineering is the leading global company developing advanced radio communication and navigation systems. We are building mission-critical infrastructure for the multi-million drone era.
Here, you will work with cutting-edge technologies tested in the most challenging environments in the world, and watch your ideas evolve into an ecosystem that safeguards humanity.
We are looking for a talented RF Hardware Engineer to join our team and contribute to the design of high-frequency and mixed-signal electronic devices. You will be involved in the full development cycle — from schematic design to prototyping and manufacturing support. This is a great opportunity to work on cutting-edge technologies and build products that matter.
You’ll collaborate closely with engineers based in Ukraine and should be eager to adopt established technical standards and methodologies from our core team.
We are seeking professionals in Finland who aspire to go beyond product development and contribute to shaping the world of tomorrow.

SKILLS & EXPERIENCE:

• Experience in high-speed design with knowledge of SI/PI principles;
• Solid understanding of RF signal path design (e.g., transmit/receive chains, filters, matching networks);
• Strong practical lab skills including test planning and signal analysis;
• Experience with modern EDA tools (e.g., Altium Designer, KiCad);
• Fluency in English and Finnish.

• 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;
• Hands-on work with spectrum analyzers, VNAs, oscilloscopes, and other high-end measurement equipment;
• Preparation and maintenance of technical documentation (schematics, BOMs, production files, test reports);
• Support for prototype assembly and design transfer to manufacturing;
• Collaboration with manufacturing partners to ensure DFM/DFT compliance.
