Job Position

We are looking for a Software Tools Developer with strong UI development experience to modernize and enhance an existing PHP-based utility used to configure optical transceivers. This utility runs on SONiC (Software for Open Networking in the Cloud)—a Debian-based network operating system—and utilizes a Flask-based UI dashboard.
You’ll take ownership of improving the user interface of this tool, adding features, testing using multiple optical modules and DAC cables. You will also work on a USB-attached module programming PCB with a GUI running on a Windows PC to expand functionality of the existing GUI to provide sequential programming ability for various cable configurations, plus other enhancements.
Depending on experience level, this role is structured as a project-based contract position, with appropriate onboarding and mentorship as needed.
