• 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.
• Responding to security incidents and triaging, containing, remediating, and reporting.
• Leveraging 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.
• 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 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.
• Experience doing security consulting and extensive hands‑on implementation.
• 3+ years of Software Engineering experience with at least one general‑purpose programming language (ex. Python, Go, 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.).

Company Overview

Roku is the TV streaming platform in the U.S., Canada, and Mexico, and we’ve set our sights on powering every television in the world. Roku pioneered streaming to the TV. Our mission is to be the TV streaming platform that connects the entire TV ecosystem. We connect consumers to the content they love, enable content publishers to build and monetize large audiences, and provide advertisers unique capabilities to engage consumers. From your first day at Roku, you’ll make a valuable—and valued—contribution. We’re a fast‑growing public company where no one is a bystander.

About the team: At Roku, our Trust Engineering team is a close‑knit group of passionate professionals with the mission to protect our customers, partners, devices, services, infrastructure, and data. We work collaboratively, sharing insights and expertise to stay ahead of the curve. Join us, and you’ll be part of a dynamic team that thrives on challenges and celebrates victories together.

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 surround ourselves with people who are great at their jobs, easy to work with, and keep their egos in check. We appreciate a sense of humor and believe that a smaller group of very talented folks can do more for less cost than a larger group of less talented teams. We’re 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 that has served us well since 2002.
