About the role

Key responsibilities & impact

As part of our Hardware Product Management team you will work with Sales and Systems Engineering teams to define product deployment use cases and architectures and drive Engineering Test and Validation team.
You’ll help develop, deploy, and maintain application notes, white papers and drive proof of concept infrastructure for high-performance optical interconnect and systems.
Your work will span technical product management, hardware testing, f/w testing, systems integration, Python development, Network deployment rules and hands-on lab experimentation, all while collaborating with experienced engineers across disciplines.
Define use cases for scale up, out and across generations of optical interconnect and switch and router families.
Educate Sales Engineering on optic interconnect deployment configurations.
Create tools for deployment rules and optical configurations for mixed rate interconnect and scale across DWDM technologies (grey and amplified direct and coherent detection DWDM, single and multi-span).
Maintain internal and external facing documentation for Data Center, ML/Ai and Scale across deployment scenarios with Arista family of products.
Create web based tools for valid configuration of Arista family of products across switch and router generations and supported optics interconnect configurations.
Work with PLM and engineering to define configurations for technical conferences.
Support engineering with equipment set-up and logistics.
Support PLM and Marketing with Material to support demonstrations.
Attend conferences to support shows as required.
Write and maintain Python-based code to automate test flows, control lab instruments, and log test results at scale.
Set up and run optical/electrical tests using tools like BERTs, power meters, spectrum analyzers, OTDR, and oscilloscopes.
Validate DWDM single and Multi-Span Systems.
Assist in analyzing test data to identify trends, troubleshoot failures, and improve product and process reliability.
Help build internal resources such as test procedures, troubleshooting guides, and onboarding documentation.
Work closely with hardware, firmware, and operations teams to ensure alignment between test systems and production goals.

Requirements

What you’ll need

A Masters degree in electrical engineering, Computer Engineering, Physics, or a related technical field.
A PhD in photonics and/or a MBA are preferred.
5 years’ experience with Optical Networking and DWDM design and deployment required.
Understanding and analysis of DWDM signal propagation and simulation as well as multi-span amplified systems an asset.
Strong writing and presentation skills, able to disseminate succinct practical knowledge to Sales and Sales Engineering.
Strong practical knowledge of Ethernet, DWDM, and Coherent Optical Technologies.
Hands-on experience with optical test equipment such as OTDR, OSA, BERT, optical power meters, Oscilloscopes etc., with solid troubleshooting skills.
Extensive experience with traffic generators and network protocol analysis tools (e.g., Wireshark, Ixia, Spirent).
Prior experience in system testing, scripting (e.g., Python, TCL), and/or new product introduction (NPI).
Proven experience testing Coherent and IMDD Transponders/Transceivers, Optical Amplifiers, Optical Mux/Demux and other optical system building blocks.
Understanding of performance monitoring parameters including Pre-FEC BER, OSNR, Chromatic Dispersion (CD), and Polarization Mode Dispersion (PMD).
Clear communication skills and a collaborative approach—you ask smart questions and contribute to team discussions.
A curious, hands-on mindset and eagerness to learn new tools and technologies.
