About the Role

As a Senior Security Engineer on the Trust Cloud team, your role involves architecting, designing, and implementing end-to-end security controls to impact the global user base. A key focus is on developing automated, scalable security solutions to enhance efficiency and protect Roku. This position requires expertise in creating and extending security automation tools, including detection and process automation.

What you will be doing

Cloud

• Designing and implementing scalable, automated security controls for AWS and GCP using infrastructure-as-code, configuration-as-code, and policy-as-code approaches (Terraform, etc.), and developing supporting automation in Go and Python.
• Partnering with infrastructure, platform, and application teams to embed security into application architectures and deployment workflows as part of a robust Secure Software Development Lifecycle (SSDLC).
• Conducting security reviews and performing threat modeling for infrastructure, platform, and application initiatives.
• Improving IAM policies, network configurations, DNS security, and cloud resource management practices.
• Designing and implementing integrations with third‑party security platforms to automate vulnerability management, secret detection, and cloud posture monitoring, ensuring findings are actionable and seamlessly integrated into engineering workflows.
• Respond to security incidents and triage, contain, remediate, and report.
• Leverage AI to accelerate your learning and enhance your work products.
• Driving security initiatives end-to-end – from identifying risks to delivering solutions – with high autonomy in a fast-moving environment.

DevSecOps

• Designing and implementing automated security controls in CI/CD pipelines using GitLab, Terraform, and policy-as-code approaches.
• Building and maintaining developer-friendly tools and workflows that integrate security checks (SAST, DAST, dependency scanning, container scanning) and secure secret management with Vault.
• Partnering with development, infrastructure, and platform teams to embed security into architecture, build processes, and deployment workflows as part of a robust Secure Software Development Lifecycle (SSDLC).
• Automating vulnerability detection, misconfiguration checks, and compliance validation across cloud and containerized environments.
• Creating reusable security automation modules, templates, and patterns for engineering teams to adopt.

We are excited if you have

• Experience doing security consulting and extensive time doing hands‑on implementation.
• 3+ years of Software Engineering experience with at least one general-purpose programming language (ex. Python, Golang, C, Rust, etc.).
• Extensive experience in either PostgreSQL or MySQL, with expertise in architecting, designing, securing, hardening, authentication, authorization, and auditing.
• 3+ years of experience working with/on BDPs.
• Developed and/or implemented data tagging, data catalogs, or other data protection related activities.
• Experience designing and administering enterprise identity and access management solutions at scale (ex: AD, EntraID, Okta, etc.).
• Experience securely running and operating web applications, web services, and service-oriented architecture in production environments.
• A proven track record of deploying and operating Kubernetes and containers in production.
• Experience deploying and operating infrastructure in other cloud providers (Azure, Oracle, IBM, etc.).

The Roku Culture

Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the company's success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. We are independent thinkers with big ideas who act boldly, move fast, and accomplish extraordinary things through collaboration and trust. In short, at Roku you'll be part of a company that's changing how the world watches TV. We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two‑part idea. We come up with the solution, but the solution isn’t real until it is built and delivered to the customer. That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
