Staff+ Software Engineer, Backend

At Praetorian, our mission is to prevent breaches before they occur. We envision a world where cybersecurity is proactive, not reactive—where organizations shift from an "assume breach" mindset to a prevention-first strategy that keeps them ahead of evolving threats.

We deliver on that vision by hiring the top 1% of offensive security talent and empowering them to tackle the industry’s most complex security challenges. Our team of elite engineers operates at the forefront of adversary simulation, application security, cloud security, and beyond.

Through red team engagements, sophisticated attack simulations, and Chariot—our fully managed continuous threat exposure management platform—we help organizations stay in control of their dynamic attack surfaces. Our human-led, tech-enabled approach allows clients to uncover and remediate exploitable vulnerabilities before they can be leveraged by real-world threat actors.

If you’re drawn to technical excellence, continuous learning, and work that truly makes an impact, you’ll thrive at Praetorian.

Career Opportunity: At Praetorian, our mission is clear: prevent breaches before they happen by emulating real-world attackers.

As part of our engineering team, you’ll contribute to the development of Chariot, our next-generation offensive security platform. Chariot is a continuously operating, semi-autonomous system designed to significantly boost the efficiency and reach of offensive cyber operations.

Imagine building an AI-powered exoskeleton for security professionals—Chariot does just that. By automating complex, multi-stage attack chains through a novel planner-and-sub-agent architecture, the platform enables faster, smarter, and more scalable security assessments—all while preserving expert human oversight and control.

This is a unique opportunity to work at the intersection of AI and cybersecurity, driving forward a platform that’s transforming how organizations defend against sophisticated threats.
