Emulation Lead/Principal Engineer

About the role

Build the platform that brings silicon to life before tapeout.

TYLsemi is developing purpose-built connectivity chiplet for HPC/rack-scale AI systems. We are seeking a Principal Engineer Emulation Lead to create scalable pre-silicon environments that enable firmware, software, and system validation months before first silicon arrives. You'll build production-grade platforms that boot real software, run meaningful workloads, expose system bottlenecks, and accelerate product readiness across the organization.

What You'll Do

• Architect and deploy full-chip, multi-die, and subsystem emulation environments using Palladium, ZeBu, Veloce, or similar platforms.

• Enable pre-silicon bring-up of boot ROM, firmware, drivers, operating systems, and application workloads.

• Develop scalable emulation methodologies and reusable infrastructure, 

• Drive system-level validation, performance analysis, and root-cause debug across RTL, firmware, software, and verification.

• Build automation, CI/CD workflows, regressions, and release processes that scale across engineering teams.

• Partner with architecture, design, verification, firmware, DFT, and post-silicon teams to reduce product risk before tapeout.

• Influence methodology, observability, debugability, and overall silicon readiness.

• Lead complex debug spanning RTL, firmware, software, and hardware platforms.

• Mentor engineers and influence architecture to improve observability, diagnosability, and product quality.

What We're Looking For

• 10+ years of ASIC/SoC development experience with significant emulation ownership.

• Expertise with commercial emulation platforms (Palladium, ZeBu, or Veloce).

• Strong RTL skills in Verilog/SystemVerilog.

• Experience with firmware bring-up, embedded processors, interrupts, and system debug.

• Proficiency in C/C++ and scripting with Python.

• Excellent cross-functional debugging and technical leadership skills.

• Proven track record leading complex verification and emulation programs.

Nice to Have

• Ethernet, PCIe, CXL or high-speed interconnects.

• FPGA prototyping (Protium, HAPS, etc.).

• Security architectures, Root of Trust, and secure boot.

• First-silicon bring-up and system qualification experience.

Why Join Us? 

You'll work at the intersection of silicon, software, and systems, helping bring cutting-edge AI and data-center products to life while influencing architecture and product quality from day one.

If you're passionate about hardware/software co-validation, large-scale emulation, and building world-class silicon platforms, we'd love to hear from you.
