Embedded Software Engineer

Your Job We're seeking an experienced Systems Integration Engineer (SIE) to lead embedded firmware integration and interoperability efforts for Active Copper Cable (ACC) and Active Electrical Cable (AEC) products used in high‑speed networking systems. This role focuses on firmware embedded within cable modules, enabling reliable link bring‑up, management, and interoperability across multiple networking protocols and platforms. In this role, you'll act as a technical authority for firmware supporting CMIS‑managed active cables, working at the intersection of the OSI Physical (Layer 1) and Data Link (Layer 2). You'll collaborate closely with hardware validation, signal integrity, and networking teams to ensure robust interoperability with systems using Ethernet, PCIe, and InfiniBand. This position is ideal for an embedded software engineer with a strong background in network devices, protocol behavior, and system‑level integration, who enjoys solving cross‑layer interoperability challenges. 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 are designing cutting edge solutions for high-speed, high-density products that maximize speed, signal integrity, and efficiency. Why Join Us? You will play a critical role in defining how embedded firmware enables interoperability for ACC and AEC products across diverse networking platforms. This role offers deep technical ownership, hands‑on system‑level exposure, and the opportunity to influence how active cable firmware behaves across Layer 1 and Layer 2 boundaries. You will work at the intersection of embedded software, hardware, and networking protocols, helping ensure reliable, scalable interoperability in lab and customer deployments . What You Will Do Embedded Firmware Integration Trouble shoot bring‑up and integration of embedded firmware within ACC/AEC cable modules Develop and integrate firmware running on DSPs, retimers, equalizers, and embedded controllers Implement and support CMIS‑based management, configuration, and telemetry for active cables Validate firmware behavior across power‑up, reset, link training, and runtime operation Protocol & OSI Layer Interoperability Debug issues spanning OSI Layer 1 (physical signaling, training, recovery) and OSI Layer 2 (link initialization, framing dependencies, error conditions) Analyze firmware behavior during system‑level link bring‑up and interoperability testing Debug, Root‑Cause, & Qualification Support Lead firmware‑centric root‑cause analysis for qualification and interoperability failures Debug interactions between firmware, hardware, signal integrity, and link‑level protocol behavior Instrument firmware to improve observability, diagnostics, and validation coverage Cross‑Functional Technical Leadership Partner closely with hardware validation, networking, and data analysis engineers Review firmware requirements, CMIS assumptions, and protocol‑specific behaviors Support technical escalations and mentor engineers on embedded firmware and interop best practices Who You Are (Basic Qualifications) Bachelor's degree or higher in Electrical Engineering, Computer Engineering, Computer Science or relevant engineering or IT related field Experience developing or integrating embedded firmware for networking or hardware-adjacent systems Working knowledge of CMIS and active cable management interfaces Experience debugging issues across physical and data link layers of the OSI model Experience resolving complex firmware-hardware interop issues What Will Put You Ahead Experience with firmware for DSP-or retimer-based interconnectsFamiliarity with link training state machines, error recovery, and protocol bring-upExperience in interoperability, qualification, or compliance testing environmentsExperience working closely with PCA design, signal integrity, or HW validation teams At Koch companies, we are entrepreneurs.
