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:
- Troubleshoot 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 interconnects
- Familiarity with link training state machines, error recovery, and protocol bring-up
- Experience in interoperability, qualification, or compliance testing environments
- Experience working closely with PCA design, signal integrity, or HW validation teams

Search Manufacturing Jobs in ArkansasManufacturing Jobs in Arkansas: Frequently Asked Questions
Which manufacturing companies in Arkansas are known to sponsor F-1 STEM OPT visas?
Arkansas manufacturers with active international hiring patterns include companies in food processing, automotive components, aerospace parts, and industrial equipment sectors. Firms such as Dassault Falcon Jet in Little Rock, Baldor Electric (an ABB company) in Fort Smith, and suppliers connected to the Walmart supply chain in Northwest Arkansas have histories of sponsoring engineering and technical roles. Checking DOL Labor Condition Application records is the most reliable way to verify a specific employer's sponsorship activity.
Which cities in Arkansas have the most manufacturing F-1 STEM OPT sponsorship jobs?
Fort Smith has one of Arkansas's strongest manufacturing concentrations, with automotive, food, and industrial equipment employers actively hiring engineering talent. Little Rock supports aerospace and defense manufacturing, particularly around its industrial corridor. Fayetteville and Springdale in Northwest Arkansas benefit from supply chain and food processing industries tied to the region's major distribution networks. These three metros account for the majority of STEM OPT-eligible manufacturing postings in the state.
What types of manufacturing roles typically qualify for F-1 STEM OPT sponsorship in Arkansas?
Roles that qualify must be directly tied to a STEM-designated degree field. In Arkansas manufacturing, qualifying positions commonly include industrial engineer, process engineer, manufacturing engineer, quality assurance engineer, supply chain analyst, and automation technician. The position must require application of STEM knowledge, and the employer must be enrolled in E-Verify. Roles classified under SOC codes linked to engineering, computer science, or applied sciences are generally eligible under the STEM OPT extension guidelines.
How do I find manufacturing F-1 STEM OPT sponsorship jobs in Arkansas?
Migrate Mate filters job listings specifically by visa type and state, making it straightforward to search for manufacturing roles in Arkansas that are open to F-1 STEM OPT candidates. Because Migrate Mate surfaces DOL Labor Condition Application data by employer, you can identify which Arkansas manufacturers have an active history of sponsoring international workers before you apply, saving time and focusing your search on employers already familiar with STEM OPT requirements.
Are there any Arkansas-specific considerations for F-1 STEM OPT sponsorship in manufacturing?
Arkansas does not impose state-level visa sponsorship requirements beyond federal rules, but the state's manufacturing sector is heavily concentrated in food processing and automotive supply chains, which means hiring cycles often align with production schedules rather than calendar-year recruiting windows. F-1 STEM OPT students should confirm their role appears on USCIS's list of STEM-designated degree programs and that their employer is E-Verify enrolled before accepting an offer, as both are federal requirements for a valid STEM OPT extension.
