Job details:
10+ years of experience in
SoC PnP Architecture within the semiconductor industry, with a strong track record of driving system-level performance, power, and efficiency investigations across complex silicon platforms.
Strong expertise in
SoC performance architecture and pre-silicon performance analysis, including:
- Hands-on experience with simulation and hardware emulation platforms such as Palladium, Veloce, ZeBu, or equivalent
- Performance analysis using cycle-accurate, transaction-level, and emulation-based environments
- Waveform-based debug and signal-level performance analysis
- Latency, bandwidth, throughput, QoS, and utilization characterization
- Transaction-level tracing and protocol debug across CHI, AXI, PCIe, CXL, or equivalent system protocols
- Identification of system-level bottlenecks across compute, interconnect, memory, and IO subsystems
- Architectural tradeoff analysis across performance, power, area, latency, bandwidth, and implementation complexity
Strong experience with
SOC Performance and Power modeling methodologies, including:
- Development and use of SystemC/TLM, analytical, trace-driven architecture models
- Building and calibrating models for performance, power, latency, bandwidth, utilization, and efficiency analysis
- Model-to-silicon correlation, including alignment of pre-silicon projections, emulation results, and post-silicon measurements
- Early-stage architecture exploration to evaluate performance, power, area, thermal, TDP, and efficiency tradeoffs
- Using models to guide SoC architecture decisions, IP configuration, memory/interconnect sizing, QoS strategy, and platform-level optimization
- Ability to translate modeling insights into clear architectural recommendations and measurable product improvements
Extensive Experience In Post-silicon Performance And Power Characterization, Including
- Silicon bring-up support from a performance and PnP perspective
- Performance counter, PMU, telemetry, and trace-driven investigations
- Correlation of pre-silicon projections, architectural models, and silicon measurements
- Root-cause analysis of performance gaps, power inefficiencies, and workload-level bottlenecks
- System-level performance tuning under real silicon constraints
- Analysis of workload behavior under power, thermal, voltage, frequency, and TDP limits
Strong understanding of
SoC system infrastructure and platform-level PnP behavior, including:
- Coherent interconnect fabrics and cache-coherency protocols
- DDR memory subsystems, memory controller behavior, scheduling, QoS, and bandwidth efficiency
- IO subsystems including PCIe, CXL
- Power management architecture, DVFS, clocking, voltage domains, power states, and throttling mechanisms
Proven experience working in both
Linux and bare-metal environments, including:
- Performance profiling and debug in Linux-based systems
- Kernel-level performance analysis and tracing using perf, ftrace, PMU-based analysis, or equivalent tools
- Low-level bring-up, debug, and performance characterization in bare-metal environments
- Understanding of boot flows, firmware interactions, BIOS/UEFI or bootloader configuration, and system initialization impacts on performance and power
- Ability to debug issues across hardware, firmware, OS, driver, and workload layers
Strong Background In Computer Architecture And Microarchitecture, Including
- CPU/GPU/NPU/DSP or accelerator performance behavior
- Pipelines, cache hierarchy, prefetching, coherency, memory systems, and interconnect behavior
- System-level performance interactions across compute, memory, IO, and power-management blocks
- Workload characterization and mapping of application behavior to architectural bottlenecks
Proficiency in
C/C++ and Python for developing:
- Performance and power analysis tools
- Automation frameworks
- Profiling and telemetry infrastructure
- Data analysis and visualization dashboards
- Correlation flows across model, emulation, and silicon data
Excellent communication and cross-functional collaboration skills, with the ability to:
- Clearly present complex performance and power findings to architecture, design, verification, firmware, software, and leadership teams
- Drive data-based architectural recommendations
- Influence SoC architecture, platform configuration, and product-level PnP decisions
- Lead investigations across multiple teams and convert debug findings into architectural improvements, tuning proposals, or product guidance

Hybrid Working at Arm
Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing the value of flexibility. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team’s needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.
