Senior Cloud Security Engineer

Tessera Labs is hiring a Senior Cloud Security Engineer to secure its cloud environments across multiple providers. The role builds security guardrails, automation, and detection, and partners with engineering, support, delivery, IT, and compliance teams.

Responsibilities:

• Own the security posture of our cloud environments across Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure, applying consistent controls across providers
• Design secure reference architectures and reusable patterns — account and project structure, network segmentation, encryption and key management, secrets management — that teams can adopt instead of reinventing
• Build security into Infrastructure as Code (IaC) through hardened modules, policy as code, and pre-deploy checks, so misconfigurations are caught before they reach production
• Secure Continuous Integration / Continuous Delivery (CI/CD) pipelines and the software supply chain: pipeline permissions, secrets handling, artifact integrity, and short-lived workload identity in place of long-lived keys
• Design and enforce least-privilege Identity and Access Management (IAM) across clouds, including role design, federation with our identity provider, and periodic access reviews
• Write code and scripts to automate security controls, remediation, and evidence collection — if you do something twice, you automate it the third time
• Operate and tune Cloud Security Posture Management (CSPM) and cloud-native security services, and drive findings through to remediation with owning teams
• Build logging and detection for cloud control-plane and workload activity, and lead the cloud side of incident response
• Contribute security controls and evidence to our compliance posture (System and Organization Controls 2, or SOC 2, ISO 27001, etc.)

Requirements:

• A DevOps foundation — you've worked in a DevOps, Site Reliability Engineering (SRE), or platform engineering role, and you've built and operated production infrastructure and CI/CD pipelines yourself, not just reviewed them
• Hands-on production experience securing at least two major cloud providers (AWS, GCP, or Azure), and a clear understanding of how their identity, networking, and logging models differ
• Deep knowledge of cloud security best practices — for example, the Center for Internet Security (CIS) Benchmarks and each provider's security foundations guidance — and the judgment to apply them pragmatically rather than as a checklist
• Fluency in proven cloud security patterns: least-privilege IAM and workload identity, network segmentation and private connectivity, encryption and key management, secrets management, centralized logging, and preventive guardrails (for example, AWS Service Control Policies or GCP Organization Policies)
• Strong coding and scripting skills in at least one general-purpose language (for example, Python or Go) plus shell scripting; you write automation other engineers can read and maintain
• Hands-on experience with IaC (for example, Terraform or OpenTofu) and with embedding security checks into it
• Strong communication skills — you work directly with engineers and can explain risk in terms they'll act on
• Familiarity with open-source cloud security tooling (for example, Prowler for posture assessment, Checkov or Trivy for IaC and container scanning, Open Policy Agent (OPA) for policy as code, Falco for runtime detection)
• Container and Kubernetes security experience (Amazon EKS, Google Kubernetes Engine, or Azure Kubernetes Service), including admission control and runtime policy
• A relevant cloud security certification (for example, AWS Certified Security – Specialty, Google Professional Cloud Security Engineer, Microsoft Azure Security Engineer Associate, or Certified Cloud Security Professional, CCSP)
• Experience securing SaaS and developer platforms, such as identity providers and GitHub organizations
• Experience supporting a SOC 2, ISO 27001, or similar program, including compliance automation platforms
• Hands-on cloud incident response or forensics experience
