Posted Nov 10, 2022 - Requisition No. 106595

Bloomberg’s NoSQL Infrastructure team offers Apache Cassandra as a hosted service. The team has visibility across the organization as we're providing a pathway for scalable data storage. We support a wide array of critical and highly-visible applications such as archival data stores, ultra low-latency market data caches and trade event stores. The team manages thousands of Cassandra nodes storing petabytes of data and billions of requests per day. The team is looking for senior engineers with an interest in distributed databases and data management to continue to drive the platform forward.

The team’s focus is to foster Cassandra adoption by improving its usability within Bloomberg. The team has developed automation workflows for managing the lifecycle of clusters, keyspace deployment and schema management. We’ve implemented client libraries for service discovery that we are looking to enhance with custom load balancing and retry policies. We also provide solutions engineering for application teams, helping them with data modeling and architecture. Currently, we are focused on improving our core automation and monitoring of Cassandra, developing a feature-rich self service console for managing Cassandra databases, and developing a proxy service to simplify data access to Cassandra. Underpinning all of this is an eye towards open source, adopting wherever possible industry standard solutions used by the open source community and contributing back patches.

If you are a software engineer who is passionate about distributed systems, and is interested in developing software infrastructure, we'd like to talk to you about an opening on our team.

We'll trust you to:

  • Help application teams looking to use Cassandra with workload characterization, performance tuning and failure analysis.
  • Improve the operability of the platform by developing infrastructure such as cluster auto-healing, containerization, and automated upgrades.
  • Improve the usability of the platform by building tooling such as our proxy service that does workload management for multi-tenant deployments and our database copy system.
  • Identify feature gaps in the technologies and work with the open source community to co-design and co-develop features and bug fixes.

You'll need to have:

  • 3 or more years of experience programming in 2 major languages (Python, Go, Java, C++, Javascript) and a willingness to pick up more as needed.
  • Experience with modern development methodologies and tools (Jira, Jenkins, Git, etc).
  • Experience with object-oriented design.
  • Strong knowledge of data structures and algorithms.
  • Strong problem solving and communication skills.

We'd love to see:

  • Upstream, accepted contributions to open source projects.
  • A strong understanding of distributed systems.
  • Production experience with NoSQL databases or other distributed storage technologies in a platform/infrastructure software engineering role.
