Requirements
Requirements
  • 8+ years of hands-on experience in application security, offensive security, or security engineering, with demonstrable depth in at least two of: offensive testing, security tooling/automation, and cloud/infra security
  • Strong offensive skills - you can manually exploit real web and API vulnerabilities beyond what a scanner will find, and you can teach others to do the same
  • Deep familiarity with building and operating security tooling in a modern engineering org: SAST/DAST/SCA pipelines, custom detection rules, secrets scanning, and CI/CD security gates. You've written tooling, not just configured it
  • Production experience with AWS (IAM, VPC, networking, data services), containerized workloads (Docker, Kubernetes/EKS), and infrastructure-as-code (Terraform or similar)
  • Comfort reading, reviewing, and contributing code in at least one language common to modern web stacks (Python, Go, Ruby, TypeScript, or similar)
  • Clear, direct communication style. You can make a sharp technical argument to senior engineers, translate risk into business terms for leadership, and write a bug report an engineer actually wants to fix
  • Strong partnership instincts - you get leverage by making other teams faster, not by blocking them
Job Responsibility
Job Responsibility
  • Run offensive assessments against Qualia's applications and infrastructure: manual penetration testing, exploit development, authenticated web/API testing, and adversarial review of new designs before they ship
  • Lead threat modeling and secure design review for the highest-risk initiatives across the company, and mentor engineers to do the same for their own work
  • Own and evolve our AppSec tooling stack end-to-end - SAST, DAST, SCA, secret scanning, IaC scanning, and the CI/CD gates that tie them together. Build the custom rules, detections, and automation that generic tooling doesn't give us
  • Harden our cloud posture: review AWS configurations, IAM policies, Kubernetes/EKS workloads, and networking boundaries
  • build automation and guardrails that prevent the same class of issue from recurring
  • Reduce toil for the team - write the tools, scripts, and integrations that turn a day of triage into a few minutes
  • Partner with Infrastructure and Platform on detection engineering, incident response support, and cross-cutting programs (secrets management, supply chain, runtime security)
  • Set the technical bar for the AppSec team: raise the quality of reviews, establish patterns others can reuse, and mentor peers across seniority levels
  • Represent AppSec in architectural reviews, vendor evaluations, and compliance efforts
