Who We Are:

X serves our community of users and customers by working tirelessly to preserve free expression and choice, create limitless interactivity, and create a marketplace that enables the economic success of all its participants.

X’s globally distributed, real-time communications network generates trillions of events and petabytes of data per day. The Realtime Storage Team provides the storage layer that enables products and services at X to be fast, highly scalable, and always available. We own Manhattan (an internally-developed distributed, persistent key-value store for low-latency high-throughput use cases), GraphStore (an internally-developed distributed database used to store relationships between users, tweets and other entities), Blobstore (an internally-developed object store), Cache (hundreds of Memcached and Redis clusters) and MySQL (tens of clusters). To handle X’s scale, we build world-class distributed storage solutions that help serve critical X services with low latency from our own datacenters. We run tens of thousands of database nodes that process hundreds of millions of requests per second!

What You’ll do:

In this role, you will: 

• Design, build and launch to production new features and improvements aimed at unifying common components across the storage systems

• Dive into performance issues and work with customers and deliver solutions to cater to customers’ latency, availability and data durability requirements.

• Actively collaborate with partner teams and our customers to build and deliver features and integrations that’ll allow us to store and retrieve data that is compliant to Privacy and Data Protection standards.

• Help us containerize X scale database services which will be the largest stateful workloads to run on Kubernetes in a datacenter hosted environment.

• Demonstrate ownership of the services you build by going oncall and lead initiatives to improve service reliability.

• Lead and drive incident responses and recovery with your peers. Review and contribute to incident postmortems and hold a high bar for the same.

• Work in a collaborative environment and uplevel your peers by doing mentoring, code and design reviews.

• Be open to develop new skills and learn on the job as we navigate new technology spaces.

• Ground your decisions with data and reasoning and adapt to new information to make informed choices.
