Employer immigration record

from this employer's Department of Labor filings

Green-card filing pattern in this occupation

Context, not a finding about this posting: of this employer's 35 green-card filings in this occupation, 100% were for a worker who already held the job.

Green-card intent detected

Samsung Semiconductor, Inc. obtained a prevailing wage determination for Electrical Engineers in San Jose, CALIFORNIA on 2026-06-09. No matching green-card filing appears in our data yet. The determination expires in 1 day (2026-09-06), and a green-card filing must follow before then or the employer starts over.+1 more active determination on file

Green-card follow-through: 44%

Of 16 labor certifications old enough to have been used, 9 expired without the employer filing the next step. Median time from filing to decision: 496 days.100% of their filings were for a worker who already held the job.Only certifications past the 180-day window are counted — recent ones cannot have expired yet.

Files H-1B transfers

126 transfer filings in the last year, covering 435 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

  • We believe innovation and growth are driven by an inclusive culture and a diverse workforce.

Responsibilities

  • Collaborate with Staff and Principal Engineers, owning a specific microarchitectural domain from idea proposal through implementation and validation
  • Participate in design implementation and validation using AI-driven design methodologies
  • Develop scripts and tools to automate and accelerate performance analysis and architectural exploration
  • We explore new architectural ideas, evaluate their performance potential, and rapidly turn promising concepts into working designs that can be validated on real silicon.
  • We also explore CPU-memory co-design from the CPU perspective, in alignment with the broader shift toward memory-centric architectures.
  • We develop and apply AI-driven methodologies to accelerate architectural exploration, broaden the design space we can investigate, and quickly iterate from ideas to implementation and silicon validation.
  • Rather than simply following established design flows, we continuously seek new ways to explore, evaluate, and realize CPU architectures.
  • The role offers an opportunity to work across the full spectrum of architecture research-from workload and performance analysis, microarchitectural innovation, and architectural modeling to implementation and silicon validation-while helping shape new methodologies for how future CPUs are designed.
  • As a Senior CPU Architecture & Performance Engineer, you will drive both microarchitectural research and performance modeling for next-generation CPU architectures.
  • You will analyze emerging workloads, develop and refine performance models, identify architectural opportunities, and turn quantitative insights into new microarchitectural concepts.

  • Hands-on experience with architectural simulators such as gem5
  • Proficiency in C/C++ and Python

Nice to have

  • Experience with RISC-V, ARM, or x86 CPU cores, or with GPU/NPU vector unit design
  • Experience with or interest in AI-driven or agentic design workflows
  • Understanding of execution patterns and characteristics of agentic AI workloads
  • Domain-specific experience in the front-end, mid-end, or back-end areas described above
  • Experience with PPA trade-off analysis
  • Experience with CPU tape-out or silicon validation
  • Experience with patents or technical publications related to CPU
  • You're inclusive, adapting your style to the situation and diverse global norms of our people.
