Firmware Developer– High‑Speed Ser Des Test Modules

HPE is seeking a Firmware Developer to design, develop, and maintain firmware for a high‑speed electrical loopback module used in manufacturing to validate HPE's next generation routers and switches.

This role sits at the intersection of firmware, high‑speed signaling, and manufacturing test, and requires hands‑on experience with Ser Des DSPs, lab debug, and hardware‑aware firmware design.

The successful candidate will work closely with hardware, systems, and manufacturing teams to deliver robust, test‑ready firmware that supports high‑volume production environments.

• Firmware Development
• Design, develop, and maintain embedded firmware for an electrical loopback module used in manufacturing test environments.
• Implement firmware features supporting high‑speed Ser Des operation, diagnostics, and monitoring.
• Develop modular, reusable, and maintainable firmware using object‑oriented design principles.
• Support firmware upgrade mechanisms and field updates.
• High‑Speed Ser Des & DSP Interaction
• Configure and manage high‑speed Ser Des functions including:
• Decision Feedback Equalization (DFE)
• Transmit FIR (TxFIR) filtering
• Eye monitoring and signal integrity measurements
• Work with Forward Error Correction (FEC) features for link validation.
• Interface with and control latest‑generation Ser Des DSPs from:
• Broadcom
• Marvell
• Credo
• CMIS & Standards Compliance
• Implement and maintain CMIS‑compliant firmware, including:
• Register map compliance
• Initialization sequences
• Application Select (App Sel) support
• Firmware download and upgrade flows
• Ensure compatibility with CMIS interoperability and compliance testing.
• MCU & Platform Development
• Develop firmware for Infineon PSoC MCUs, including peripheral configuration and board‑level bring‑up.
• Integrate MCU firmware with external Ser Des DSPs and system control interfaces.
• Hardware Debug & Lab Work
• Perform hands‑on hardware bring‑up and debugging using:
• High‑speed oscilloscopes
• Logic analyzers
• Emulators and in‑circuit debuggers
• Collaborate closely with hardware engineers to diagnose board‑level and signal‑integrity‑related issues.
• Manufacturing & Test Enablement
• Design firmware with Design for Test (DFT) and Design for Manufacturing (DFM) principles in mind.
• Support manufacturing test flows, automation, and diagnostics.
• Develop firmware hooks and features to enable efficient high‑volume testing and fault isolation.
• Collaboration & Code Quality
• Use Git or SVN for source control and participate in structured code reviews using Gerrit.
• Contribute to architecture discussions, design reviews, and documentation.
• Follow best practices for coding standards, version control, and continuous improvement.

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience.
• Strong experience in embedded firmware development.
• Hands‑on knowledge of high‑speed Ser Des systems and signal integrity concepts.
• Experience working with Broadcom, Marvell, and/or Credo Ser Des DSPs.
• Solid understanding of Forward Error Correction (FEC) in high‑speed links.
• Experience developing on Infineon PSoC MCUs or similar embedded platforms.
• Familiarity with CMIS specification and compliance requirements.
• Proficiency with Git or SVN and Gerrit‑based code review…
