Why This Role?

Ready to build AI agents that revolutionize enterprise security? The North Security team is looking for a Senior Software Engineer to create autonomous systems that handle the complex, critical tasks security practitioners face every day.

Your Role:

As a Senior Software Engineer focused on agentic security, you'll build intelligent systems that empower security teams. Your responsibilities will include:

• Build autonomous security agents that perform alert triage, secure code reviews, threat modeling, and vulnerability assessment

• Develop agent orchestration systems that help security practitioners automate repetitive security tasks

• Design and implement agent security controls to ensure our AI agents can safely interact with sensitive enterprise data

• Create the security infrastructure that allows agents to operate in high-trust environments with stringent deployment requirements

• Ship production-ready agent capabilities that run efficiently in resource-constrained environments

• Research and implement novel security patterns for AI agent systems, sometimes requiring custom solutions where standard libraries fall short

• Conduct security testing of both the agents you build and the platform that runs them.

You may be a good fit if:

• 5+ years of software engineering experience with a track record of shipping user-facing security features

• Strong Python development skills with significant production experience

• Experience building or working with autonomous systems, AI agents, or intelligent automation

• Solid understanding of security principles including session management, authentication, authorization, and secure coding practices

• Ability to think about security at multiple layers: application security, agent behavior security, and infrastructure security

• Comfortable working across the full stack and diving into unfamiliar codebases to understand and fix issues

• Thrive in fast-paced environments where you can adapt to evolving priorities

• Excited about the intersection of AI/ML and security engineering.

If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply!

We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities.
