Responsibilities Build production-grade software that powers Bloomberg’s global infrastructure
Design and implement scalable, fault-tolerant systems with a focus on observability, performance, and automation
Collaborate across engineering teams to introduce automated, self-service operational workflows
Conduct deep systems analysis and root cause investigations for complex, distributed systems
Propose and prototype innovative approaches to reliability and risk mitigation
Contribute to design docs, runbooks, and post-incident reviews—clear communication is part of the job
Team We’re the Site Reliability Engineering team within Bloomberg’s Application Middleware group. Our mission is to ensure that Bloomberg’s core connectivity and messaging layers are resilient, scalable, and fully observable. We own systems that operate at high throughput and low latency, including:
Gateways: Secure, high-performance TCP/SSL entry points to our data centers
HFN & NSTP: A global HTTP CDN and SOCKS5 proxy network delivering fast access from any geography
Playlist Services: Dynamic path configuration systems optimizing user connectivity in real-time
PGM Relays: Infrastructure for reliable multicast data delivery
We use automation, observability, and software engineering to detect issues before they impact customers and reduce manual toil wherever we can.
Qualifications A degree in Computer Science, Engineering, Mathematics, or equivalent practical experience
Strong software engineering skills in any high-level language (we mainly use Python and C++)
A deep understanding of software system reliability and risk management—including how to identify potential points of failure and design mitigation strategies
A good understanding of data structures, algorithms, and system design
Experience navigating and improving large, distributed codebases
An ability to identify system risks and engineer around points of failure
Clear written and verbal communication, including technical documentation and incident analysis
We’d Love to See We are building a team with a breadth of expertise and value depth in any of the following areas:
Systems Knowledge: A strong grasp of operating systems, fundamental networking protocols (TCP, UDP, multicast), or core database concepts as they apply to modern infrastructure
Cluster Management: Experience with deployments, staging, and configuration management. Direct experience with Argo and/or Kubernetes or other Pipeline Management Platforms is a significant advantage
Machine Management at Scale: Experience with capacity planning and automating the lifecycle of large machine fleets
System Observability and Monitoring: Deep understanding of SLIs/SLOs/SLAs, alerting, and building dashboards for complex systems
Reliability in Distributed Systems: Knowledge of fault tolerance and the unique challenges of network and node failure in distributed environments
Mentoring: Proven experience mentoring and growing junior Engineers
