- AI first approach to assess, design, triage and fix issues. Produce shareable AI artifacts for others to scale fixing issues
- Deep expertise in static analysis (SAST), software composition analysis (SCA), and secret scanning across JVM ecosystems (Java, Spring Boot, Grails) and Python
- Strong hands-on coding ability - you can read, write, and fix code in Java, Python, and Groovy
- Production experience securing Kubernetes workloads on AWS EKS or Azure AKS
- Solid understanding of container security - image scanning, runtime protection, least-privilege configurations
- Strong knowledge of end-to-end encryption - TLS/mTLS implementation, certificate management, PKI, key rotation, and secrets management (HashiCorp Vault, AWS KMS,Azure Key Vault)
- Proven experience conducting threat modeling on product requirements - ability to partner with product teams early in the SDLC to identify and mitigate risks before implementation
- Working knowledge of network security: ingress/egress controls, TLS termination, mTLS, VPC/VNET segmentation
