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 Senior Rust / GPU Software Engineer
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. Every engineer owns large parts of the system, from design to production.
Responsibilities
- Design and build fast, reliable software for real-time signal processing.
- Turn research algorithms (GNSS, signal processing, geospatial) into efficient production code.
- Write and tune GPU kernels, and keep the GPU busy with work sent asynchronously from the host.
- Build and improve the infrastructure the team relies on: build system, testing, CI, tooling.
- Work closely with hardware, research, and product teams.
- 5+ years of hands-on experience shipping production software.
- Strong C++ or Rust skills, with emphasis multi-threaded and async code with careful handling of resources and their lifetime.
- Good judgment about performance, reliability, and code quality.
- Experience with using performance analyses tools.
You must also have at least one of these
- GPU programming: you wrote GPU kernels (CUDA or similar) that run in production, and made them fast. This includes running them asynchronously from the host and overlapping host and GPU execution.
- Building complex systems from scratch: you designed and built a significant system, or a major part of one, starting from nothing. Not only features inside an existing system. Examples: core runtime, build system, CI and automation, test framework.
We are looking for builders. Long experience on a small part of a large, established codebase is not enough on its own.
Nice to have
- Knowledge of GNSS.
- Experience with signal processing or computer vision.
- Experience turning Python prototypes into real-time production code.
- Experience with embedded GPU platforms (e.g. NVIDIA Jetson).
- Experience with mixed C++/Rust codebases (FFI, CMake + Cargo)
Skills Required
- Bachelor's degree in Computer Science, Mathematics, Electrical Engineering or related technical field
- At least 3 years of hands-on experience in C++ development
- Solid working knowledge of Python
- Strong analytical and problem-solving skills
- Excellent communication and teamwork abilities
- Ability to excel in a fast-paced startup environment
- Experience with CUDA or GPU-accelerated computing
- Familiarity with GNSS technologies and domain concepts
- Experience in geospatial data processing and algorithms
- Background in computer vision
- Experience with signal processing
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.
