We are currently looking for a skilled and dedicated Software Performance Engineer to join our team in the Optical Networks organization. As a member of the Photonic Product Assurance Team, your primary responsibility will be to ensure the quality and performance of the software developed for our Reconfigurable Line System (RLS) product.

RLS is a high-capacity networking platform with advanced software capabilities. It features an intelligent control plane for fast service activation and improved availability, ensuring rapid adaptation to problems, outages, and other issues that could impact network performance. The open APIs and micro-services architecture enable seamless integration and customization, enhancing operational efficiency and service velocity. These APIs facilitate seamless integration with existing management and back-office systems, allowing operators to leverage their current infrastructure investments. The openness of the platform also enables collaboration with third-party systems and applications, providing flexibility and choice for network operators.

As a leader within the team, one of your primary responsibilities will be to provide guidance and direction to a team of designers, ensuring they conduct effective performance investigations that align with current priorities. You will play a critical role in ensuring that designers have a thorough understanding of the use cases and performance targets, empowering them to effectively address any performance issues that may arise. Leveraging your deep understanding of customer use cases and requirements, you will play a pivotal role in shaping software design that consistently meets and surpasses high-performance standards.

In this role, you will be responsible for analyzing and optimizing software performance, with a specific focus on critical RLS use cases such as control plane traffic restoration following an outage, declarative config, streaming telemetry, zero-touch provisioning, span calibration, software upgrades and circuit pack restarts. You will collaborate with design teams to ensure efficient feature design, provide documentation and training on performance guidelines and best practices, automate performance analysis, and contribute to improving the software delivery pipeline to proactively detect performance issues before they impact the production environment.

Responsibilities:

The successful candidate will join the Photonic Product Assurance Team. Specific responsibilities include:

• Provide technical leadership and guidance to a team of designers, ensuring their effective participation in performance investigations.
• Foster a collaborative and innovative team environment, empowering designers to address performance issues and drive continuous improvements.
