Senior Security Engineer - Cloud Security

ABOUT THE ROLE

We are looking for a Senior Security Engineer with deep cloud security expertise to own complex security workstreams across our multi-cloud environment and drive our vulnerability management program to the next level of maturity. This is a senior individual contributor role for a security engineer who independently leads complex technical initiatives, influences security decisions across engineering teams, and serves as a trusted cloud security subject matter expert. The role combines deep technical execution with cross-functional influence, while partnering with Security leadership and the Principal Security Architect on broader security strategy and architecture direction.

You will operate across cloud security posture management, infrastructure hardening, vulnerability program leadership, and secure DevOps practices, with the seniority to make independent technical judgments, lead cross-functional security initiatives, and mentor colleagues. This role partners closely with the Principal Security Architect to operationalize cloud security standards, implement security controls, and execute security initiatives across Nasuni's cloud environments. You are equally comfortable diving deep into cloud configurations, reviewing security architecture, and advising engineering teams on security trade-offs.

WHAT YOU WILL DO

Cloud Security Engineering and Posture Management Lead initiatives that continuously improve Nasuni's cloud security posture across AWS, Azure, and GCP, including workload security, IAM hardening, network segmentation, encryption, and least-privilege enforcement. Lead cloud security assessments and configuration reviews, identifying and remediating misconfigurations and security gaps using Wiz and cloud-native tools. Drive zero-trust initiatives and cloud-native security controls across our multi-cloud infrastructure.

Partner closely with the security leadership to translate architectural standards into enforceable, operational controls, and provide ground-level feedback to shape those standards. Evaluate and implement security controls for container and Kubernetes workloads, CI/CD pipelines, and Infrastructure as Code. Contribute to cloud security architecture and design reviews by providing implementation guidance, operational security expertise, and risk assessments for new technologies and infrastructure changes.

Vulnerability Management Program Ownership Lead execution and continuous improvement initiatives within Nasuni's vulnerability management program, partnering with Security leadership to influence strategy, tooling direction, prioritization frameworks, and program maturity across AWS, Azure, and GCP. Assess and enforce vulnerability SLAs and risk-based prioritization frameworks aligned to business risk appetite. Analyze vulnerability data across environments, synthesize trends, and produce executive-ready reporting on exposure, remediation velocity, and risk posture.

Drive systemic remediation through collaboration with DevOps, SRE, IT/infrastructure, and engineering teams, moving beyond ticket-by-ticket fixes toward structural improvements. Continuously tune and optimize scanning coverage, detection fidelity, and platform configuration across all vulnerability management tooling. Identify program gaps, define improvement roadmaps, and present recommendations to security leadership.

DevSecOps and Infrastructure Hardening Partner with DevOps and SRE teams to embed security controls into CI/CD pipelines, IaC templates, and cloud provisioning workflows.
