Job description

We are seeking an experienced Applications Engineer specializing in advanced high-speed Ethernet SerDes technologies. In this key technical role, you will bridge the gap between silicon architecture, firmware development, hardware qualification, and customer implementation.

You will work closely across cross-functional groups—including ASIC design, manufacturing, test, calibration, and reliability teams—while providing technical leadership and direct customer engagement.

What you'll do

Technical Leadership & Customer Engagement

• Direct Customer Interaction: Drive direct technical support, debug complex issues, and deliver technical training for customers and Field Application Engineers (FAEs).
• Cross-Functional Collaboration: Lead hardware/software bring-up efforts in collaboration with ASIC, manufacturing, test, calibration, and reliability engineering teams.
• Project Management: Manage multiple complex tasks and project timelines concurrently.

Hardware & System Integration

• Schematic & Layout Review: Review PCB schematics and board layouts for high-speed signal integrity and hardware compatibility.
• Lab Debug & Measurement: Perform hands-on debugging using Ethernet traffic generators, high-speed oscilloscopes, jitter analyzers, spectrum analyzers, network analyzers, and OTN testers.

Education & Experience

• Degree: BS, MS, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or equivalent.
• Experience: 8-10+ years of practical experience in high-speed hardware, SerDes, or system/board engineering.

What we're Looking For

• SerDes & PHY Expertise: Strong working knowledge of high-speed (224Gbps / 112Gbps+) PHYs and SerDes architectures.
• Ethernet & Optical Standards: Deep knowledge of 100Gbps / 200Gbps / 400Gbps optical systems and standards; OTN experience is a plus.
• PAM4 Modulation: Hands-on experience with PAM4 signaling and high-speed Signal Integrity (SI) analysis.
• SoC Architecture: Experience in architecture, programming, or support of complex System-on-Chip devices.
• Direct experience with MACsec (802.1AE) key management and data-plane acceleration.
• PTP (IEEE 1588) hardware timestamping / clock recovery synchronization in optical hardware.
• Reliability & Failure Analysis: Background driving product qualification, stress testing, reliability investigations, and board-level failure analysis (FA).

Compensation

The compensation range shown below represents total target cash compensation and includes both base salary and target bonus. Actual compensation will vary based on factors such as experience, skills, qualifications, job level, and work location.

In addition to cash compensation, this position is eligible for equity in the form of stock options, giving you the opportunity to share in the Company’s long-term growth and success.
