About the Job

As a senior software engineer on the Server Platforms team, you will be responsible for building and supporting the Akamai versions of standard Linux kernel distributions, while ensuring the integrity and operational robustness of the system on the various hardware platforms on which it is deployed. You will participate in activities such as updates, security fixes and/or optimizations, performance benchmarking and integration testing of Akamai extensions to the kernel API, required to expose the kernel status to key applications so that the application can cooperate with the kernel functions to maximize throughput.

About the Team

The Server Platforms team develops and supports communications and the data collection infrastructure for Akamai's distributed platform. This infrastructure is comprised of a kernel, an operating system, and a series of core components which serve as a baseline for the rest of the Akamai networks. These systems distribute configuration data, control information, and customer traffic to Akamai's distributed servers. They also publish, aggregate, and deliver internal system and customer data for use by internal and customer-facing monitoring, alerting, and reporting applications. These systems are among the largest in the world, which brings unique engineering challenges for developing distributed, scalable, and fault-tolerant systems.

Responsibilities:
In this work opportunity, you will participate in:
  • Supporting a project for improving the kernel performance on the ESSL network and helping provide protection against DDOS attacks.
  • Rebasing the Akamai Kernel API tailored to upstream changes in the baseline kernel, which often requires re-integration and functional unit testing as codelines change.
  • Evaluating kernel and system performance on a variety of hardware platforms and under various workloads.
  • Benchmarking the Akamai kernel against all variants of our hardware platform, to determine the correct sysctl tunings that will maximize performance on each.
  • Incorporating publicly available drivers for special hardware as necessary and testing to ensure proper functionality and performance
  • Tracking, evaluating, and integrating new technology.
  • Troubleshooting issues as they arise either in QA or on the production networks.
  • Evolving the world's largest distributed computing and content delivery systems.
  • Modifying standard Linux kernel distributions to suit Akamai’s business needs.
  • Supporting other Akamai groups when they have questions on system services and kernel features.

  • Minimum 2 years experience using the Debian component packaging architecture.
  • Minimum 2 years experience evaluating, incorporating, and testing various Linux drivers.
  • Minimum 3 years experience with C/C++.
  • Minimum 1 year experience with Perl.
Desired Qualifications
