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 looking for Junior / Mid-level Software Engineer – Rust / C++ / GPU
About the role
We build a real-time GNSS and SDR signal processing system that runs on embedded GPU platforms.
Algorithms and hardware interfaces are written in C++ and CUDA. Infrastructure is written in Rust.
The team is small. You will work next to senior engineers and own real parts of the system early on.
What you will do
- Write fast, reliable code for real-time signal processing.
- Help turn research algorithms (GNSS, signal processing, geospatial) into production code.
- Write and tune GPU kernels.
- Improve the build system, tests, CI, and tooling the team uses every day.
- Work with hardware, research, and product teams.
- Up to 1–3 years of experience as SW Engineer
- Good programming skills in C++, Rust, or both, and a wish to go deep into systems programming.
- Comfortable on Linux.
- Curious about how things work under the hood: memory, threads, performance.
- Likes to build things from start to finish, not only small changes.
Strong plus
- GPU programming: you wrote GPU kernels (CUDA or similar), even in a personal or university project.
- Building projects from scratch: you designed and built a working project on your own or in a small team. For example a tool, a library, an engine, or a build/test setup.
Nice to have
- Interest in GNSS, signal processing, or computer vision.
- Experience with Python, especially turning prototypes into faster code.
- Contributions to open source.
Skills Required

- Understanding of memory, threads, and software performance
- Ability and interest to develop systems software deeply
- GPU kernel programming experience using CUDA or similar
- Experience building a complete project from scratch
- Interest in GNSS, signal processing, or computer vision
- Python experience, particularly optimizing prototypes
- Open-source contributions
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.
