About The Team:
We have grown rapidly to where we are today serving billions of HTTP requests daily.. We achieved this scale by writing scale-sensitive components in languages like Rust and Go. This potent combination of high performance with efficient resource utilization has given us an incredible competitive edge.
We are hiring a Platform Engineer to help us continue to scale by operating and engineering the future of our infrastructure. We are maintaining 99.95% uptime today, and we are investing to ensure we maintain that as the business continues to grow and as the product evolves.
Your primary task will be software engineering with a focus on infrastructure, operations, and automation. You'll be building systems to run our product, improving internal services, and advising product teams on architecture as it relates to the operability of the service.
The systems you'll be responsible for include all of the services which power our product. This ranges from off-the-shelf services like PostgreSQL, Scylla, Redis, Kafka, Kubernetes, etc. to our in-house services such as the Rails web app, various Rust backend services, and our high-performance API layer written in Go.
You'll be working with Kubernetes to automate our data center operations and writing operational services to automate database operations. One of the key challenges in this role is to not only understand systems to the point of being able to manually operate by hand but also to understand in sufficient detail to write software systems to automate such operations.
