Regulus is an agile defense-tech startup tackling the most complex challenges in counter-drone and uncrewed defense. With hundreds of combat-proven systems deployed by the IDF and global partners, we are now engineering the next generation of C-UxS (Counter-Uncrewed Systems). We leverage advanced electronic warfare and kinetic measures to detect and neutralize hostile threats. If you want to push technological boundaries while safeguarding Israel and our allies, join us at this pivotal stage of our growth.
This is a unique opportunity to join a company at a pivotal growth stage and help shape its products, culture, and future.
We are seeking a Senior RF Engineer to design and implement next-generation communication architectures for autonomous platforms, including drones. This role sits at the intersection of RF engineering, digital signal processing (DSP), and security research to advance our mission-critical wireless systems.
Key Responsibilities
- Develop, simulate, and integrate RF systems and building blocks, including transmitters, receivers, power amplifiers, filters, and frequency-generation components.
- Plan and execute RF validation, testing, and measurement activities using professional lab equipment such as spectrum analyzers, network analyzers, and oscilloscopes.
- Work closely with digital hardware and software teams to ensure seamless system-level integration.
- Prepare and maintain clear technical documentation while coordinating development activities across multiple organizational interfaces.
- Take responsibility for assigned tasks, contributing as a senior hands-on team member while collaborating across departments.
- B.Sc. in Electrical or Electronics Engineering (an M.Sc. is considered an advantage).
- 10+ years of practical experience in RF system development, covering design, simulation, integration, and testing phases.
- Proven experience designing and characterizing RF modules such as UWB transmitters & receivers, high-power power amplifiers, and filters.
- Hands-on experience performing RF measurements and validation using spectrum analyzers, network analyzers, and oscilloscopes.
- Solid knowledge of diverse antenna technologies and their associated performance trade-offs.
- Understanding of integration workflows involving RF, digital hardware, and software components.
- Ready to work in a fast-paced, dynamic startup environment.
Preferred Qualifications
- Background in communication systems and/or military-grade systems.
- Experience working in defense-related organizations or under military standards.
- Exposure to project coordination or technical leadership of small teams.
- Strong troubleshooting capabilities with the ability to work independently.
- Hands-on work with certification compliance-related activities

What We Do
Regulus closes the critical gap between long-range strategic systems and the last few hundred meters of point defense, providing the autonomous last line of defense against drones and other uncrewed threats. Regulus C-UxS solutions redefine modern defense against uncrewed threats with AI-powered, decentralized mesh and point-defense systems and networks. Our soft-kill EW Ring family and the DART hard-kill interceptor can each be deployed as independent products; powered by LeC2 and Orchestra - our autonomous mesh command-and-control network - they seamlessly connect to create Ring Origami, an integrated close-in defense layer that detects, coordinates, and neutralizes current and future close-range threats in real time - with no person on the loop. While most defense startups focus on tactical-range interception (2–5 km) - an approach whose effectiveness is rapidly eroding as threats harden, communications improve, and autonomy and maneuverability increase - Regulus is building the resilient, close-range shield modern forces need around them. Strategic systems such as lasers, missiles, and other long-range interceptors remain essential for extended-range defense, a domain dominated by primes due to its complexity, cost, and long development cycles; Regulus complements these systems by securing the final meters. Built on unmatched combat experience and hundreds of combat-proven systems, Regulus is creating a scalable, multi-domain C-UxS architecture designed to outpace emerging threats. As defense and homeland security markets accelerate their demand for next-generation autonomy, Regulus is positioned to become a new-era defense leader - driving the counter-uncrewed revolution and defining the future of intelligent defense infrastructure.
