Blue Teamer / Defensive Security
As a Blue Teamer at Ctrl+G, you will build the defensive side of the equation. Attackers are getting faster. AI-generated code is shipping with vulnerabilities baked in. Human review is disappearing. Your job is to design the detection logic, response frameworks, and defensive training environments that teach models to catch what humans no longer can.
You will work at the intersection of traditional defensive security and AI. This means building systems that detect vulnerable code patterns at scale, designing realistic defense scenarios for model training, and developing the foundations for autonomous agents that can monitor, detect, and respond to threats without human intervention.
Representative projects
- Designing defensive benchmarks that measure whether models can detect vulnerabilities, triage alerts, and respond to incidents autonomously.
- Building detection pipelines that identify insecure patterns in AI-generated code before it ships to production.
- Creating training environments that simulate real-world defense scenarios—SOC operations, incident response, threat hunting—to teach models how defenders actually work.
- Developing evaluation frameworks for autonomous defense agents: can they contain a breach, patch a vulnerability, harden a system without human oversight?
You may be a good fit if you
- Have strong experience in defensive security: detection engineering, incident response, threat hunting, or SOC operations.
- Have built or operated security tooling at scale—SIEM, EDR, or custom detection pipelines.
- Thrive in a fast environment, with radical candor (we don't like bs).
- Believe that defense can be automated and that AI is the path to getting there.
- Understand that the best defenders have played offense—and can think like an attacker to build better defenses.
