Overview
Senior Linux Kernel Engineer role at Bloomberg. The Managed Systems Integration Engineering (MSIE) group provisions, configures, and maintains Bloomberg’s production fleet using infrastructure-as-code and open-source tools to ensure a scalable and reliable environment.
Within MSIE, the Systems Internals team focuses on kernel-space performance and configuration standards, developing tooling for networking stack functionality, and advising on how best to optimize interaction between applications and OS interfaces.
What’s In It For You
You’ll work with modern, open-source tooling while maintaining mission-critical systems hosting a wide array of applications for the Bloomberg Terminal product. You will collaborate with OS and service-owning teams to maintain stability and performance of operating systems and servers. You will advise on the design, architecture, and utilization of enterprise-class operating systems with a focus on Linux. You will have the opportunity to develop performance tooling and test the latest kernels and their features, as well as contribute back to the open-source community.
Responsibilities
* Build and evolve eBPF-based tools to enhance observability of the network and other operating system layers
* Improve Bloomberg’s internal Linux kernel regression testing framework
* Contribute to upstream Linux kernel development and enhancement requests
* Investigate and resolve complex kernel and network performance issues in partnership with application teams
* Develop tools that improve telemetry and deepen visibility into application behavior under various system loads
* Create internal documentation to support knowledge sharing and engineering best practices
Qualifications
* Deep understanding of the Linux kernel including the virtual memory, VFS, IPC, network, and process scheduling subsystems
* Proven experience in system performance tuning—balancing low latency vs. throughput, NUMA optimization, and hardware/BIOS configuration
* Ability to create robust testing and certification processes to evaluate the impact of hardware changes, tunables, and system software updates to the Bloomberg application stack
* Proficiency in reading and debugging C source code to troubleshoot kernel-space issues
* Eagerness to work with a group, share knowledge, and contribute to team goals
* A Degree in Computer Science, Computer Engineering or related technical field, or equivalent work experience
We Would Love To See
* Experience working with and developing in the Linux kernel, either using eBPF, as a kernel developer, or building low level programs in C
* Experience programming in Rust or Python
* Experience with applying formalized performance analysis methodologies such as the USE Method to address complex problems
* Familiarity with one or more of the following technologies is preferred: Chef, SaltStack, Jenkins, and Ansible
