System Architect - High-Performance Computing

About the role

AheadComputing is looking for a System Architect to define and own the architecture of high-performance computing systems, from system-level models through to integration with foundry partners. The role is open to candidates based in Austin, Texas or Portland, Oregon.

Key responsibilities

• Define and document system-level architecture, data flows, memory maps and transaction models, including NoC topology, power and clock domains and interface requirements.
• Define how the product is partitioned across dies, the die-to-die topology and memory provisioning across the package.
• Build and extend system-level performance models, run workload-driven analysis and correlate them against microarchitectural models and RTL.
• Diagnose divergence between model and implementation and turn model output into architectural recommendations.
• Coordinate delivery and integration of internal and external IP, including interconnects such as PCIe, DDR, HBM and AMBA CHI NoC.
• Work with foundry and design service partners on SOW definition and technical deliverables, and define and drive PPA targets.
• Collaborate with firmware, software and verification teams, and mentor other engineers.

Required profile

• Bachelor's, Master's or PhD in Electrical Engineering, Computer Engineering, Computer Science or a related field.
• 6+ years in SoC or ASIC architecture, design or integration, or in system-level performance modelling.
• Strong knowledge of SoC architecture and design principles, and experience documenting system-level architecture requirements.
• Ability to present a quantitative argument clearly enough to change an architectural decision, and to lead vendor discussions.

Required skills

• Experience with on-chip interconnect protocols and architectures.
• Proficiency in C++ and Python for modelling, analysis and automation.
• Preferred: RISC-V or Arm CPU architecture, AMBA CHI, 2.5D/3D packaging and chiplets, UCIe, LPDDR/HBM memory modelling, workload characterisation and PCIe.

What we offer

• Lead impactful architecture decisions shaping next-generation heterogeneous computing.
• Competitive compensation and benefits package.
• Collaboration with engineers passionate about CPU technologies, opportunities for professional growth and a flexible, inclusive work culture.
