Job description

Overview

Join to apply for the Senior DevOps Engineer role at Roku.

Teamwork makes the stream work. Roku is changing how the world watches TV. Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and we’re working to power every television in the world. We pioneered streaming to the TV, and our mission is to be the TV streaming platform that connects the entire TV ecosystem by linking consumers to content, enabling publishers to build and monetize audiences, and providing advertisers with unique capabilities to engage viewers.

From your first day at Roku, you’ll make a valuable contribution. We’re a fast-growing public company where no one is a bystander, offering opportunities to delight millions of TV streamers while gaining experience across disciplines.

About the Team

The Advanced Development team pushes boundaries beyond product lines to build genuinely new things. We work on foundational technologies that could impact every Roku device in the future and explore ideas outside standard shipping cadences and timelines.

We are seeking exceptional talent for an exceptional team. Team members are experts who collaborate, own decisions, and push against convention to build something singular and new. They foster trust and have little room for drama.

About The Role

With over 80 million global users, Roku aims to create products that “just work” with an intuitive, magical experience out of the box. We are seeking a skilled Sr. DevOps Engineer to join the Advance Development Team. This team builds and scales Roku’s platform, utilizing technologies such as Kubernetes, Istio, Envoy, and other OSS/CNCF–supported tools. You will drive Roku’s transition to a unified, cloud-agnostic system, maintain and enhance our service mesh, observability platform, and CI tooling.

We’re looking for engineers who thrive in collaborative environments, enjoy cross-team work, and are passionate about automation, security, and data-driven metrics like SLOs and SLAs. If you’re proficient in Kubernetes, the CNCF ecosystem, and enjoy optimizing workloads and simplifying debugging for teams, this role is ideal. Join us to shape Roku’s infrastructure future.

What you’ll be doing

• Work on AWS ECS, Kubernetes & Service Mesh to manage our growing fleet of clusters globally
• Identify feature gaps, bugs, scalability issues, and other challenges when working with internal customers
• Collaborate with internal teams, stakeholders, and partners to implement effective solutions
• Provide daily support to customers as they onboard and use our platforms, helping them optimize value, performance, and reliability
• Contribute to enhancing platform capabilities with a focus on reliability and scalability
• Conduct feature, functionality, and usability trials for new tools that could benefit Roku
• Exhibit strong communication skills and maintain a support-oriented approach when interacting with both technical and non-technical audiences

We’re excited if you have

• Extensive experience in Infrastructure engineering, DevOps and/or Software Engineering, with a focus on cross-team engagement
• Familiarity with ECS, Kubernetes, and Istio as the platform architecture, and how they integrate and scale
• Expertise with open-source observability tools in large-scale environments (Datadog, Prometheus, Grafana, ELK, Jaeger, Kiali, Loki, etc.)
• Past success in supporting a large engineering team on a central platform; strong interpersonal skills and constructive communication are key
• The drive and self-motivation to understand intricate details of a complex infrastructure
• Ability to work independently in a highly distributed, multi-national team across time zones
• Hands-on experience with AWS and/or GCP
• Experience with scripting or infrastructure languages (Terraform, Helm, Shell, Python) and being part of on-call rotations
• B.S. or M.S. in Computer Science, Engineering, or equivalent experience

Benefits

Roku is committed to offering a diverse range of benefits as part of our compensation package to support employees and their families. Benefits include global mental health and financial wellness resources, and local benefits such as healthcare (medical, dental, vision), life, disability, commuter, and retirement options (401(k)/pension). We support time off for vacation and personal reasons. Not all benefits are available in every location or role; consult your recruiter for details specific to your location.

The Roku Culture

Roku is a fast-paced place where everyone focuses on the company’s success. We value talented, easy-to-work-with people who keep egos in check and appreciate a sense of humor. We believe a smaller number of highly capable people can achieve more than a larger team with less talent. We’re independent thinkers with big ideas who act boldly, move fast, and achieve extraordinary things through collaboration and trust. Roku is changing how the world watches TV.

We think of ourselves primarily as problem-solvers who build and deliver solutions to customers. This practical approach to innovation has defined Roku since 2002.
