Job description

4+ years of experience in SoC PnP Architecturewithin 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 investigationsCorrelation 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

Use of AI in Your Application

At Arm, we embrace the benefits AI can bring, including in recruitment. You may use AI to support your preparation, such as improving the clarity of written responses, practicing interview questions, or learning more about our industry. However, your application and interview responses must reflect your own thinking, experience, and abilities. We want to understand your authentic perspective, creativity, and approach to problem solving. As such, you may not use AI to complete assigned tasks as part of any assessments. If you plan to use AI-supported or assistive technologies as part of a reasonable adjustment, please contact [e-mail] so we can support you.

Recruitment Adjustments and Accommodations

At Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email [e-mail]. To note, by sending us the requested information, you consent to its use by Arm to arrange for appropriate accommodations. All accommodation or adjustment requests will be treated with confidentiality, and information concerning these requests will only be disclosed as necessary to provide the accommodation. Although this is not an exhaustive list, examples of support include breaks between interviews, having documents read aloud, or office accessibility. Please email us about anything we can do to accommodate you during the recruitment process.

Hybrid Working

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.
