The role

Broadcom’s ASIC Product Division (APD) is focused on enabling customers to develop products with a sustainable and substantial competitive advantage. APD does this by delivering best-in-class technology platforms, easy-to-integrate bleeding-edge intellectual property, and by providing world-class customer support. APD’s customers span a wide range of industries developing ASICs for the largest and most complex cloud computing AI engines, supercomputers, networking, and advanced wireless solutions.

We are seeking a Die-to-Die (D2D) Applications Engineer to serve as the primary technical resource for internal and external customers integrating and deploying our proprietary D2D PHY IP in silicon. This role bridges hardware, firmware, and software, providing deep technical support across the full IP lifecycle — from RTL integration and simulation through silicon bring-up and production. You will develop expert-level knowledge of our D2D PHY architecture (hardware and software/firmware) and become the go-to engineer for solving complex, cross-domain integration and debug challenges.

While prior D2D PHY experience is a strong plus, we place equal or greater weight on candidates who are exceptional at root-causing hard problems that span RTL, firmware, and system-level interactions.

What you will do

Responsibilities

Provide hands-on technical support to internal and external customers integrating the D2D PHY IP into their ASIC and products
Debug and resolve Verilog/RTL simulation issues encountered during customer integration
Support internal DFT (Design-for-Test) and ATE (Automated Test Equipment) production test development teams with PHY-specific technical guidance
Assist external customers with silicon bring-up, characterization, and production test/debug support
Triage and resolve firmware-related issues and questions from customers using the PHY’s embedded software/firmware stack
Diagnose issues that span multiple layers — RTL, firmware, and system/software — and identify root cause across hardware/software boundaries
Develop and maintain deep expertise in the architecture, functionality, and operation of the proprietary D2D PHY (hardware and software)
Create and improve internal documentation, debug guides, and application notes based on recurring customer issues
Work cross-functionally with design, verification, firmware, product engineering, and DFT/test teams to escalate and close out issues
Participate in customer-facing technical discussions, including simulation reviews, bring-up sessions, and post-silicon debug

What Success Looks Like

Customers (internal and external) view you as a trusted, responsive technical resource for D2D PHY integration and debug
Simulation and bring-up issues are triaged quickly and routed to root cause efficiently, whether the issue lives in RTL, firmware, or system integration
Internal DFT/ATE teams get the PHY-specific support they need to develop robust test coverage
Recurring issues are captured and turned into documentation that reduces future support burden

What you need

A Bachelor’s Degree in Electrical or Computer Engineering or equivalent, and 5+ years of related experience; or Masters degree and 3+ years of related experience
Demonstrated hands-on experience running and debugging Verilog simulations
Strong debugging skills across at least two of the following domains: RTL/digital logic, firmware, embedded software, or system-level hardware
Comfort working at the intersection of hardware and software — able to trace an issue from a software/firmware symptom down to a hardware or RTL root cause (or vice versa)
Solid understanding of digital design fundamentals and standard chip-level interfaces/protocols
Strong communication skills, with the ability to explain complex technical issues clearly to both internal engineering teams and external customers
Self-directed and comfortable owning ambiguous, open-ended debug problems
Scripting skills (Python, Ruby, Tcl) for debug automation and log analysis
Familiarity with embedded firmware development or debug (C/C++, register-level debug, on-chip debug tools)

Nice to have

Direct experience with Die-to-Die (D2D) PHY IP, chiplet interconnects, or other high-speed SerDes/PHY IP
Experience with silicon bring-up, lab debug equipment (oscilloscopes, logic analyzers, protocol analyzers), and characterization
Experience supporting DFT and/or ATE test development (scan, BIST, test pattern debug)
Prior experience in an applications engineering, field applications engineering (FAE), or customer-facing technical support role
