The Team:

The Bloomberg Managed Services organization (BMS) is responsible for creating and curating Bloomberg Engineering's "as a Service" software catalog and infrastructure. We develop and integrate products into a simple, sophisticated user interface and provide a concise way for engineers to create data-store and middleware instances.

The BMS Queuing Core team focuses on building and maintaining BMQ, Bloomberg’s very own distributed message queue framework. BMQ provides durable, efficient, and highly available queues by means of persistence, clustering, and replication. While many internal Bloomberg teams already rely on BMQ for their production needs, we have several exciting projects which aim to add more features, reliability, and capacity to BMQ. You will work on projects which will expose you to how to design a client API, design an efficient wire protocol over TCP, implement robust distributed consensus among several nodes, and everything in between!

We work with:

  • C++ for the core BMQ message broker.
  • C++, Go, Rust, Python, and Java for the client SDKs.
  • Raft consensus algorithm for broker coordination and log replication.
  • Jepsen & TLA+ for distributed system verification.
  • SDLC practices, including Docker-based testing, CI, API documentation standards, etc.

We'll trust you to:

  • Collaborate within an agile, multi-disciplinary team.
  • Develop key features of the BMQ message broker, its client libraries, and its ecosystem.
  • Elevate BMQ into a complete, self-sufficient, generic message queue system that we can share with the Open Source community.
  • Pick up on new frameworks, experiment, and build software that works seamlessly in various environments.
  • Anticipate engineering needs and expectations from Bloomberg engineers, and build solutions that work for them.
  • Collaborate directly with product owners and application teams to understand requirements, conduct feature demos, and provide system design consultations.

You'll need to have:

  • 4+ years of programming experience with C++
  • A degree in Computer Science, Engineering or similar field of study or equivalent work experience.
  • Strong communication and collaboration skills.
  • Strong understanding of distributed systems, data structures, algorithms and system design.
  • Experience with multi-threaded programming.
  • Commitment to writing meaningful unit tests and integration tests.

We'd love to see:

  • Passion for distributed systems and large scale data systems.
  • Experience designing and implementing high volume and high availability distributed system.
  • Experience maintaining and contributing to large Open Source projects.
  • Familiarity with network protocols (particularly TCP).
  • Familiarity with distributed consensus protocols like Raft, Paxos, etc.
  • Familiarity with Kubernetes and Docker.
