Senior Software Engineer/SRE - Core Communications

About Core Communications (CC):

We build the core messaging products that power Bloomberg’s internal and client communication: IB (Instant Bloomberg), MSG (Message), and other collaboration platforms. These systems are used by the financial industry to exchange billions of messages daily, from trade ideas and pricing quotes to mission-critical communications. We're building the backbone of financial dialogue, operating at massive scale and high stakes.

About our Team:

The Core Communications SRE team are the guardians of reliability and stability for all CC products. Our focus is on enabling teams to build and operate resilient, observable, and scalable systems. We define standards, provide tools, and lead reliability-focused initiatives across all stages of the development lifecycle. Our scope spans infrastructure, application health, and incident response, working closely with over 100 developers and multiple product and platform teams.

We view our systems holistically, from application code and cluster provisioning to monitoring pipelines and reliability governance. As our platforms evolve and scale, we proactively identify architectural and operational risks, and partner with teams to mitigate them. This includes defining meaningful SLOs with Product, strengthening our observability stack, and developing cross-cutting tools that improve diagnosis and response.
