About The Position

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, DevOps, 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).

Requirements

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 or external equivalent.
At least 7+ years of direct relevant work experience in cloud security engineering, application/product security or a similar role
At least 5+ years of experience in cloud engineering, infrastructure engineering, security engineering, DevSecOps, SRE, or related technical disciplines.
Significant hands-on experience securing production AWS environments including: Strong understanding of AWS IAM, including policies, roles, trust policies, permission boundaries, federation, cross-account access, and least-privilege design; Strong knowledge of AWS networking, including VPCs, subnets, routing, security groups, network ACLs, VPC endpoints, load balancers, DNS, and private connectivity.
Experience securing Kubernetes and containerized environments, including EKS or comparable managed Kubernetes platforms.
Hands-on experience with AWS security services such as CloudTrail, Config, GuardDuty, Security Hub, Inspector, IAM Access Analyzer, KMS, and Secrets Manager.
Experience implementing infrastructure using Terraform, CloudFormation, or comparable Infrastructure-as-Code technologies.
Experience with Git-based development and CI/CD workflows.
Strong understanding of networking concepts, including TCP/IP, DNS, TLS, routing, firewalls, proxies, and network segmentation.
Working knowledge of Linux and common infrastructure technologies.
Highly motivated self-starter that can manage multiple deliverables independently in a fast-paced environment
Ability to develop automation using Python, PowerShell, Bash, or similar scripting languages.
Understanding of common cloud attack techniques, identity-based attacks, privilege escalation, credential compromise, and infrastructure security vulnerabilities.
Demonstrated ability to independently troubleshoot complex technical security and infrastructure problems.
Strong written and verbal communication skills with the ability to communicate effectively with security professionals, engineers, architects, and technology leadership.
Highly motivated self-starter that can manage multiple deliverables independently in a fast-paced environment
Broad knowledge across the security, insider threat, risk management and compliance domains.
Proficiency in scripting and automation (e.g., Python, PowerShell, Terraform)
Familiarity with container security technologies (Docker, Kubernetes).
Have familiarity with infrastructure as code (IaC) tooling
Knowledge of encryption and key management practices.
Excellent risk based problem-solving, analytical, and communication skills.
Ability to work independently and as part of a team.
