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. We offer you the opportunity to delight millions of TV streamers around the world while gaining meaningful experience across a variety of disciplines.

About the Role

As a Senior Security Engineer, Cloud, on the Advanced Development 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 designing and implementing secure cloud infrastructure and platforms.

About the team

The Advanced Development organisation pushes beyond the boundaries of product lines to build new things. We think independently of standard shipping cadences and timelines, working on foundational technologies that will impact every Roku device in the future, and on ideas that no one has seen before in their living room. As this is an exceptional team, we are seeking unusual talent. As part of Advanced Development, the Developer Experience team specifically focuses on driving internal changes in tooling to improve developer satisfaction and productivity. The team listens to their customers, determines the most impactful opportunities and executes on delivering those changes. The team works in technologies including modern Linux embedded C++, CI systems, complex AWS cloud backend systems, and web platforms.

What you will be doing

• Using your prior knowledge of Terraform, Kubernetes, Linux, and Native AWS components to securely design and deploy virtual devices for partner collaboration, utilizing best practices to minimize costs, ensure protection of intellectual property, and maximize reliability.
• Perform upgrades and deployments of software via infrastructure as code using Terraform to ensure auditability and consistency from release to release.
• Developing supporting automation in Go and Python.
• Lead efforts to evaluate new technologies and methodologies, pushing for best practices including secure code and design reviews and implementing automation to ensure high‑quality code.
• Self‑managing project priorities, deadlines, and deliverables.
• 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.
• 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.

We are excited if you have

• Security consulting experience, including extensive hands‑on implementation.
• Experience securely running and operating web applications, web services, and service‑oriented architecture in production environments.
• 5+ years deploying software and applications using managed Native AWS Services and Kubernetes in a production environment.
• Experience managing Linux environments.
• Ability and desire to lead the design and implementation of backend services, coupled with a deep understanding of different application platforms.
• A breadth of security knowledge and best practices, including network isolation, least privilege, zero trust, and secrets management.
• Experience with various protocols and data formats such as REST, WebSockets, HTTPS, JSON, and Protobuf.
• Rust/C++ as bonus coding experience.
• Bachelors or Master’s degree in Computer Science, Engineering, or equivalent.

Benefits

Roku is committed to offering a diverse range of benefits as part of our compensation package to support our employees and their families. Our comprehensive benefits include global access to mental health and financial wellness support and resources. Local benefits include statutory and voluntary benefits which may include healthcare (medical, dental, and vision), life, accident, disability, commuter, and retirement options (401(k)/pension). Our employees can take time off work for vacation and other personal reasons to balance their evolving work and life needs. It’s important to note that not every benefit is available in all locations or for every role. For details specific to your location, please consult with your recruiter.

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 few number of very talented folks can do more for less cost than a larger number 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, one that has served us well since 2002.
