The Senior Cloud & Infrastructure Security Engineer is a senior technical member of the Information Security organization responsible for designing, implementing, and maintaining security controls across cloud and infrastructure environments.

This is a hands-on engineering role that works closely with Site Reliability Engineering (SRE), Platform Engineering, Infrastructure, Dev Ops, and application development teams to ensure security is engineered into cloud platforms and infrastructure from the outset. The objective is to make secure configurations the default, allowing engineering teams to move quickly while maintaining appropriate security controls.

The successful candidate will combine deep cloud and infrastructure expertise with strong security engineering skills. This individual will have the technical capability and authority to implement security controls directly, including AWS IAM policies and roles, VPC and network security controls, cloud security guardrails, logging and monitoring, encryption controls, and Infrastructure-as-Code (IaC).

• Design and maintain AWS security controls across IAM, VPC, encryption, monitoring, and cloud-native services.
• Apply least-privilege access, secure networking, encryption, logging, and monitoring standards.
• Support secure adoption of AWS services by translating cloud risks into technical safeguards.

• Partner with SRE, Platform, Infrastructure, Dev Ops, and development teams to secure enterprise platforms and cloud infrastructure.
• Define secure baselines, hardening standards, reusable guardrails, and preventative controls for infrastructure technologies.
• Review infrastructure designs to identify security gaps and recommend scalable remediation.

• Build and maintain security controls through Infrastructure-as-Code using Terraform, Cloud Formation, reusable modules, and templates.
• Integrate automated policy, configuration, vulnerability, and compliance checks into CI/CD pipelines.
• Embed security testing and guardrails into deployment workflows to reduce manual review.

• Centralize and protect cloud security telemetry for monitoring, detection, and incident response.
• Partner with Security Operations to investigate incidents and build automated detection and remediation capabilities.
• Use logs, alerts, and findings to improve detection coverage and response readiness.

• Conduct security architecture reviews and translate risk requirements into practical technical controls.
• Communicate cloud and infrastructure risks, business impact, and remediation options to stakeholders.
• Develop reference architectures, security patterns, technical standards, and engineering guidance.
• Other tasks as assigned by manager

• Bachelor’s degree in a technical field from an accredited college/university, or equivalent job experience.
• Minimum of 8+ years of industry and/or relevant experience, typically with 2+ years in an AVP level role…
