Systems Integration Engineer

We’re seeking an experienced Systems Integration Engineer (SIE) to lead hardware validation and interoperability efforts for Active Copper Cable (ACC) and Active Electrical Cable (AEC) assemblies used in highspeed networking systems. This role is focused on systems containing embedded PCAs with DSPs, retimers, equalizers, power management, and control interfaces, integrated directly within the cable module.

In this role, you will serve as a technical authority for PCAbased cable module bringup, debug, and systemlevel interoperability, working across hardware, firmware, signal integrity, and networking teams. You will drive rootcause investigations, evaluate design robustness, and help define validation best practices for electronically complex interconnects.

This position is ideal for an experienced engineer who thrives at the intersection of PCA hardware, embedded electronics, and networking system interoperability.

Our Team

Molex’s Copper Solutions Business Unit (CSBU) is a global team that works together to deliver exceptional products to worldwide telecommunication and data center customers. CSBU is one of the most highly technically advanced business units within Molex. Our engineering teams design cutting edge solutions for high-speed, high-density products that maximize speed, signal integrity, and efficiency.

Why Join Us

You will be getting in on the ground floor of a booming sector inside Molex as part of a team building the infrastructure and processes that enable worldclass interoperability testing. This role offers deep technical ownership, visibility into product readiness, and the opportunity to influence how embedded cable electronics interoperate at scale. You will work handson with advanced interconnect technology and play a key role in ensuring robust, repeatable interoperability across lab and customer environments.

What You Will Do

ACC / AEC Hardware & PCA Validation

• Lead bringup and validation of ACC/AEC cable assemblies with embedded PCAs
• Validate DSP, retimer, and equalizerbased designs against electrical, functional, and interoperability requirements
• Assess PCA behavior within the cable module including power, resets, control interfaces, and signal integrity impacts
• Validate systemlevel interactions between cable PCAs and switches, NICs, and host platforms

Interop Debug & RootCause Analysis

• Lead investigation of interoperability issues involving active cable PCAs
• Perform deep lab debug across PBCA hardware, embedded firmware, signal integrity, and link training layers
• Drive rootcause analysis for link failures, marginal performance, powerup issues, and qualification escapes

Design Review & Validation Strategy

• Review PBCA schematics, layouts, and design tradeoffs impacting signal integrity, power, thermals, and reliability
• Evaluate how PBCA design decisions affect interoperability across vendor platforms
• Define validation strategies and best practices specific to PCAbased cable modules
• Capability to interpret schematics, layouts
• Familiarity with PCB tools like Cadence Allegro, Raspberry Pi and STM debuggers

Technical Leadership & Escalation Support

• Partner with firmware integration, networking, SI, and data analysis engineers
• Provide technical leadership during customer interoperability escalations
• Mentor engineers and influence validation standards across the Interop organization

• Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, or a related field
• Strong experience validating PBCAbased active interconnects or embedded hardware systems
• Handson expertise with lab debug, instrumentation, and systemlevel bringup
• Proven ability to lead rootcause analysis across PCA hardware, firmware, and networking interfaces
• Strong technical communication skills and crossteam collaboration

What Will Put You Ahead

• Experience with DSP or retimerbased cable designs
• Background in highspeed signal integrity and embedded power architectures
• Familiarity with networking interoperability and compliance environments
• Experience setting validation strategy for electronicsenabled cable products
