**Description & Requirements**

Are you passionate about building high-performance systems that are fast, resilient, and operate at global scale? Join Bloombergu2019s Application Middleware SRE team, where youu2019ll combine software engineering and systems expertise to keep the backbone of the Bloomberg Terminal running smoothly for hundreds of thousands of users around the world.

Weu2019re not your typical SRE team. Weu2019re embedded in a group that powers real-time connectivity, and we own systems where uptime isn\’t just importantu2014itu2019s essential to the global financial system. This is your opportunity to engineer resilience at scale, automate critical infrastructure, and shape reliability practices across one of the worldu2019s most powerful tech platforms.

**The Team**

Weu2019re the Site Reliability Engineering team within Bloombergu2019s Application Middleware group. Our mission: ensure that Bloombergu2019s 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.

**What Youu2019ll Do**
Build production-grade software that powers Bloombergu2019s 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 reviewsu2014clear communication is part of the job

**Youu2019ll Need to Have**
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 managementu2014including 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

**Weu2019d 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
