Opportunity

This role combines deep technical security engineering with operational assurance and platform enablement. The position is responsible for shaping and sustaining secure development practices, strengthening cloud and SaaS controls, and improving detection and response maturity across Quantexa.

You will work closely with engineering, platform, and operational teams to build secure delivery patterns and ensure they are consistently adopted. This includes guiding DevOps team approaches, embedding automated security testing, consolidating compliance checks, and influencing design standards that support secure development and deployment. You will provide both assurance and hands on oversight to ensure tooling such as CI/CD, infrastructure as code, identity controls, and container orchestration remain hardened, monitored, and aligned to recognised best practices.

On the operational side, you will lead the improvement of security controls and monitoring capabilities across cloud platforms, SaaS services, and enterprise toolsets. You will integrate threat intelligence, refine detection rules, enhance incident readiness, and drive remediation activities based on security posture findings. You will work with stakeholders to review architectural risk, conduct threat modelling, and support operational response to emerging issues.

Success in this role requires an ability to translate complex risks into actionable change, influence adoption of secure practices, and build trust with engineering and senior technical stakeholders. You will balance preventative engineering activities with investigative skills and operational discipline, creating a feedback loop that strengthens resilience over time.

The ideal candidate brings strong experience across cloud security, DevOps enablement, identity and access controls, SaaS security, threat detection platforms, and incident response. You will be a self-starter who can navigate ambiguity, challenging stakeholders, collaborate across varied teams, and drive holistic improvements that enhance Quantexa's overall security posture.

The role is open in New York, New Jersey, Connecticut, North Carolina, Massachusetts, Pennsylvania, Virginia, Maryland, Washington, D.C., and Florida.
