Why we read it this way (8)
The role is a hybrid (On-site Flex or Virtual Flex) requiring 1–3+ days per week on-site at a Lam or customer/supplier location in the San Francisco Bay Area; it is not fully remote.
The salary range ($141,000–$307,000/year) is explicitly stated as applicable only to California/San Francisco Bay Area applicants.
The title is plain 'Software Engineer' with no level modifier, so advertised seniority is Unspecified; however, the 7+ years requirement and end-to-end ownership scope support a Senior classification.
SOC classification is Medium confidence: the role is primarily software engineering (building production AI systems, agentic pipelines, infrastructure), but the heavy ML/AI modeling emphasis (evals, fine-tuning, RL) creates some overlap with Data Scientists (15-2051).
LangGraph is listed as the primary named orchestration framework; MCP and 'agent SDKs from major model providers' are presented as interchangeable alternatives in the same requirement.
MCP (Model Context Protocol) also appears independently as a build target ('Build MCP Servers'), so it is retained as a separate skill in addition to its role as an alternative to LangGraph.
LangSmith, PEFT, and RLHF appear only under Preferred Qualifications and are marked accordingly.
'Semiconductor equipment experience' is listed as a preferred qualification but names no specific technology or tool, so it is omitted from the skills list per extraction rules.
