Systems Integration Engineer

Your Job

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 high-speed 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 PCA-based cable module bring-up, debug, and system-level interoperability, working across hardware, firmware, signal integrity, and networking teams.

You will drive root-cause 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 world-class 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 hands-on 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 bring-up and validation of ACC/AEC cable assemblies with embedded PCAs


* Validate DSP-, retimer-, and equalizer-based designs against electrical, functional, and interoperability requirements


* Assess PCA behavior within the cable module including power, resets, control interfaces, and signal integrity impacts


* Validate system-level interactions between cable PCAs and switches, NICs, and host platforms

Interop Debug & Root-Cause 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 root-cause analysis for link failures, marginal performance, power-up 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 valida...
