Your Impact

We are seeking a visionary Software Engineers to join our newly formed Autonomous Security team. This is not a traditional "monitor and patch" role. In this position, you will be at the forefront of the next evolution of cybersecurity: Autonomous (AI) Security Team.

Your mission will be to design, build, and deploy AI agents that act as autonomous security researchers and first responders. You will move our security posture from "Human-in-the-loop" to "Human-on-the-loop," creating a self-healing infrastructure that identifies, tests, and mitigates vulnerabilities at machine speed.

AI Agent Development: Build and fine-tune LLM-based agents to perform automated vulnerability research and code analysis.

Autonomous Remediation: Develop "self-healing" pipelines that automatically generate, test, and deploy security patches and dependency updates via Kargo and ArgoCD.

Threat Mitigation: Design AI-driven logic to detect anomalous traffic patterns and autonomously update WAF rules or service mesh configurations to neutralize external threats in real-time.

Pipeline Integration: Integrate AI security tooling directly into our CI/CD lifecycle, ensuring that security is an automated, invisible, and frictionless part of the development process.

Security Orchestration: Build the "nervous system" that connects security scanning tools (Snyk, Wiz, etc.) with AI agents to prioritize and resolve alerts without manual triage.

Minimum Qualifications

DevSecOps Expertise: demonstrated ability in DevOps or Security Engineering, with a deep understanding of CI/CD, Kubernetes, and cloud-native security.

AI/ML Familiarity: Demonstrable experience (or strong project portfolio) working with Large Language Models (LLMs), Prompt Engineering, or building Agentic workflows

Automation Mastery: Expert-level proficiency in Python or Go, and experience with Infrastructure as Code (Terraform, Pulumi).

Cloud-Native Stack: Hands-on experience with Kubernetes, Service Mesh (Istio/Linkerd), and GitOps tools (ArgoCD, Kargo).

Security Mindset: Solid understanding of the OWASP Top 10, CVE lifecycles, and modern exploit techniques.

Preferred Qualifications

Familiarity with vector databases (Pinecone, Milvus) for security context retrieval.

Familiarity with "Policy as Code" (OPA/Rego).
