Through building tools and products for other engineers, our infrastructure team acts as a team multiplier - think auto-scaling, horizontal sharding, scalable storage systems, application performance monitoring, database optimization, and more. We are in the early phases of scaling out our next-generation cells architecture that will support a scale orders of magnitude greater than what we can today. Curious? Talk to us, we’d love to tell you more.

What will you be doing?

• Building and automating our next-generation cells architecture, a horizontal scaling platform that allows us to support growing customers all over the world.

• Automate rebalancing of our customers across our cells to spread the load (without downtime!)

• Design and implement a new Kubernetes staging environment that engineers can spin up in under a minute.

• Build tools to scale developer workflows for a >50 person engineering team, for example, schema migration automation tool to run online MySQL migrations across a large number of production database shards.

• Troubleshoot and resolve low-level bugs and issues, e.g. memcached throughput exceeding AWS caps, network partitions in our AWS VPC

• Design, deploy and operate asynchronous work queues, high-volume storage systems, high-throughput systems: You should not be afraid of writing code that will decide to start or stop 1000 servers

What skills and experience do you need?

• Be excited about cloud infrastructure!

• Product mindset, we’re a product company on a mission to “advance how people work”

• Industry experience with highly available, large-scale distributed systems at a large-scale internet service.

• Experience working on software systems built atop Amazon Web Services.

• Fluency in a dynamic language like Node.JS, Python, Rust, or similar.

• Strong track record of launching and delivering projects of significant complexity and high level of ambiguity.

• Understand the trade-offs in employing different technical solutions to a problem, valuing pragmatism over idealism.
