Sr. Platform Engineer, Cloud

About Quizlet:
Inspired by our belief that anyone can learn anything and powered by our own curiosity, we build the smartest tools we can imagine to help students learn.  
Quizlet is the popular, global learning platform and app that millions of students, teachers and everyday people use to study any subject imaginable for school, work or as part of their personal interests -- including two-thirds of high school students and half of all college students in the US. Combining cognitive science and machine learning, Quizlet guides students through adaptive study activities to confidently reach their learning goals. We’re on track to become the undisputed leader in user-generated learning content and engagement, at the scale of YouTube.  
Valued at $1 billion, Quizlet has raised over $60 million in venture capital from investors including Icon Ventures, Union Square Ventures, General Atlantic, Costanoa Ventures, Owl Ventures, and Altos Ventures.  
To serve our global community of learners, our teams tackle lofty technical challenges and design for use cases across cultures and languages. We work hard, act like owners, and collaborate every chance we get. We’re energized by the potential to power more learners through multiple approaches and various tools.

About the Team:
Quizlet’s Platform Engineering team get big things done. We are a team of curious individuals with experience in software engineering, site reliability, traffic shaping, developer experience and all things backend. We love to solve scaling challenges as code. We strive to build resilient distributed systems that scale while enabling developer velocity. We build, evolve and operate tools, frameworks and infrastructure that handle application delivery from source to production. 
We run production in Kubernetes and continue to modernize other parts of the infrastructure using cloud-native technologies. We follow the gitOps philosophy to perform continuous delivery. We follow Infrastructure as Code (IaC) practices to automate all things infrastructure and application delivery. We follow Agile development methodologies. 
Quizlet embraces a philosophy of service ownership by empowering service developers to build highly observable, reliable, and resilient services.
About the Role:
On an average day you are empowered to solve strategic projects or figuring out solutions to continue making our systems more resilient. There’s always something new to look at, and new teams to work with. You’ll be working on strategic projects aiming to increase service resilience, improve observability, and enhance our delivery pipelines. You will build, extend or improve existing tools/frameworks that not only reduce toil but also enable other teams and our own team to perform other projects/tasks faster, securely and reliably.

In this role, you will:

• Enable Quizlet’s growth by solving scaling and infrastructure problems 
• Drive automation to reduce toil
• Improve our ability to understand and respond to the performance of our systems.
• Enhance observability
• Use a combination of skills in systems engineering, development, configuration management, networking or others to build and run distributed, fault-tolerant software systems and infrastructure
• Be in the thick of solving problems of running systems at scale
• Support production by participating in an on-call rotation 

What you bring to the table:

• You feel energized by solving unique problems 
• You feel passionate about automation and building resilient products 
• You enjoy building the system integrations needed to enable product engineers to deliver  secure and reliable services
• You are proficient with containers, Kubernetes and Terraform
• You are fluent in at least one of our languages (Python, GoLang, Typescript, Kotlin or PHP) and willing to dive into other ones, as needed
• You have familiarity with monitoring frameworks, RUM, and APM
• You are proficient in incident management/response best practices with large scale distributed systems 
• Systematic problem-solving approach, coupled with good communication skills and a strong sense of ownership
• Ability to work across team boundaries to identify and solve pain points that affect engineer velocity and system resilience

Bonus points if you have:

• Significant production experience with Kubernetes at very large scale
• Familiarity using service mesh implementations with a proxy (Istio, LinkerD, Consul Connect, Envoy)
• Expertise in building platforms that enable networking services to be delivered via software to enable Product teams to be self sufficient in networking configuration of the services they own
• Familiarity with Hashicorp products like TFCloud and Vault
• Proficiency with Google Cloud Platform
