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 a visionary, tech-savvy Lead Full-Stack Engineer to act as the technical backbone of our team, driving the end-to-end design and delivery of our next-generation, AI-powered C2 platform. This is a highly influential role for a proactive problem-solver who loves to challenge the status quo, brainstorm innovative solutions, and bridge the gap between product vision and complex technical execution. If you have a passion for cutting-edge architecture and pushing system upgrades in a mission-critical environment, this is the role for you.
Key Responsibilities
- Act as the driving force behind technical ideas and system upgrades; proactively propose architecture improvements and new solutions across the entire stack.
- Define and oversee the architecture of distributed systems, ensuring seamless integration between robust backend systems (real-time data ingestion, analytics) and high-performance, user-facing frontend interfaces.
- Serve as the architecture expert who connects the platform to AI capabilities, while leveraging advanced AI development tools daily to accelerate prototyping, UI/UX design, and backend logic.
- Lead code reviews, mentor team members technically across the full stack, and work closely with product stakeholders to balance technical complexity with seamless user experience.
- Maintain a sharp technical edge by contributing directly to core implementation, complex problem-solving, and critical infrastructure
- 7+ years of overall experience in software engineering, with a proven track record of delivering complex, production-grade Full-Stack products end-to-end.
- 5+ years of deep, hands-on experience with JavaScript across the entire stack (Node.js for Backend and modern frameworks like React/Vue/Angular for Frontend).
- Strong background in System Architecture, encompassing distributed systems, backend ecosystems (APIs, databases, data pipelines), as well as frontend state management and performance optimization.
- Proven experience building architectures that integrate with, orchestrate, or visualize AI/ML systems and data-driven decision platforms.
- Proficiency in leveraging AI development tools (such as Claude Code or equivalent) to accelerate development, automate workflows, and drive engineering efficiency.
- problem-solver mindset with a strong passion for innovation, leading technical initiatives, and pushing for system upgrades.
- Experience with real-time or mission-critical systems – Advantage.

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.
