Senior Devops Engineer, Production Infrastructure Engineering Job - Netflix - Remote/Virtual (EXPIRED) | ShowbizJobs.com

 

 

Job Description

• Netflix is the largest production studio in the world.
• The Production Infrastructure Engineering team is responsible for building the infrastructure platform that enables artist collaboration on a global scale.
• We work closely with peer engineering teams in Digital Production and Animation Technologies, Platform Engineering, and other central engineering teams at Netflix.
• Do you have a passion for solving customer needs with technology and making their experience the best it can be?
• Would you enjoy being an early hire in a highly visible space with the opportunity to build a team and shape our products?
• Are you interested in defining and building the technical future of the studio production platform?
• We are highly collaborative and focused on building scalable and foundational services for other engineering teams.
• Much of the content created today happens at the intersection of technology and art, and our platform is what powers the creative applications and tools artists use to make Netflix content across the globe.
• Our team provides the services such as workstations and rendering, as well as systems and software foundations that power a global footprint of collaborative artist work environments both in the cloud and near premises.
• We are seeking a Senior DevOps Engineer with extensive Windows domain experience to join our Production Infrastructure Engineering team.

 

About the Role:

We are looking for a Senior DevOps Engineer who is excited by working with partner teams to build custom solutions to satisfy a wide range of artist needs.

 

Our Opportunity

• Be part of a team that's building a service that instantiates and orchestrates a variety of workstation instances across a heterogeneous infrastructure.
• Operate and support the virtual workstations that power the NetFX Platform.
• Partner to identify needs, understand security requirements, and improve the artist's experience.
• Work cross-functionally with Engineering teams to manage systems and services that provide reliable and scalable solutions supporting the artist experience.
• Join an environment where different backgrounds, cultures, industry and life experiences are embraced and valued.

Your Experience

• You have contributed to ''always-on'' servers, services, agents, or APIs using tools and languages like PowerShell, Chocolatey, Java, Go, Python, JavaScript (NodeJS), C++ or Ruby. We only use some of these, but experience in any one of them is enough.
• You have technical curiosity and are ready to help across the team and learn new skills.
• You have a strong bias for automation and taking the time to think about the right way to solve a problem versus quick fixes or band-aids.
• Knowledge of cloud compute and storage, including public cloud vendors (AWS, GCP, or Azure).
• Experience using build and deployment tools such as Jenkins, Docker, and Terraform.
• Experience with operational tools like AWS CloudWatch, Splunk, and SaltStack.
• Experience working in Linux and Windows environments.

What is Infrastructure as Code with Terraform? | Terraform | HashiCorp Developer

 

• Terraform can manage infrastructure on multiple cloud platforms.
• The human-readable configuration language helps you write infrastructure code quickly.
• Terraform's state allows you to track resource changes throughout your deployments.
• You can commit your configurations to version control to safely collaborate on infrastructure.

 

 

What is IaC with Terraform? - Logic

 

To deploy infrastructure with Terraform:

• Scope - Identify the infrastructure for your project.
• Author - Write the configuration for your infrastructure.
• Initialize - Install the plugins Terraform needs to manage the infrastructure.
• Plan - Preview the changes Terraform will make to match your configuration.
• Apply - Make the planned changes.
