About this opportunity
AheadComputing, Inc. lists this System Architect opportunity in northern, Kentucky. Review the employer’s description below for duties, qualifications and application requirements.
Job description
Define and document system-level architecture, data flows, memory maps, and transaction models for high-performance computing systems; specify NoC topology, power domains, clock domains, and interface requirements.
Define how the product is partitioned across dies, the die-to-die topology, and how memory is provisioned across the package.
Build and extend system-level performance models to evaluate partitioning options, die-to-die topology, memory provisioning and package composition.
Run workload-driven analysis to set credible targets and test whether architectural choices meet them.
Quantify what crosses the die boundary for a given partitioning, and what that costs in bandwidth, latency and power.
Correlate architectural models against detailed microarchitectural models, and both against RTL, so projections can be trusted.
Own the correlation methodology and the regression infrastructure that keeps it honest as the design moves.
Diagnose divergence between model and implementation and drive it to root cause.
Turn model output into architectural recommendations, with the assumptions and sensitivities stated.
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 deliverable management.
Define and drive PPA targets at chip, subsystem, and IP levels.
Collaborate with firmware, software, and verification teams on functional and PPA requirements.
Represent architecture decisions across teams, and mentor other engineers as the role grows.
Qualifications & Skills
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.
Experience with on-chip interconnect protocols and architectures.
Demonstrated experience building or substantially extending performance models used to make real design decisions.
Proficiency in C++ and Python for modelling, analysis and automation.
Ability to present a quantitative argument clearly enough to change an architectural decision.
Strong written and verbal communication, and the ability to lead vendor discussions.
Preferred Qualifications & Skills
RISC-V or Arm CPU architecture, including cache and memory hierarchy design.
AMBA CHI network-on-chip, and system-level cache behaviour.
Advanced packaging: 2.5D and 3D integration, chiplet architectures, and die-to-die interfaces such as UCIe, BoW and CoWoS, including partitioning and floorplan trade-offs.
Experience correlating a performance model against RTL on a program that reached silicon.
LPDDR or HBM memory subsystem modelling - scheduling, page policy, bank and rank parallelism.
Workload characterisation methodology, including reuse-distance and roofline analysis.
Foundry ecosystem familiarity, including scaling behaviour across node transitions.
PCIe, UCIe, DDR/LPDDR and HBM.
High-performance or server-class CPU experience.
