Senior AI Systems Engineer / Architect - US-CA-Santa Rosa-Bldg 4, United States
$156,740 - $261,230 USD yearly
Originally posted 23 October 2026 by the employer.
About the role
As a Senior AI Systems Engineer / Architect, you will define and build the architectural backbone connecting AI reasoning with Keysight engineering tools, data, models, services, and products. The role spans software simulators, digital models, hardware-in-the-loop emulators, and physical measurement instrumentation.
What you'll do
- Architect and implement core agentic systems connecting LLMs and reasoning models with engineering tools, APIs, data services, and product workflows. - Design orchestration and multi-agent reasoning flows using graph-based or tool-calling architectures with explicit semantics for state, context, memory, and execution. - Build backend services, REST or gRPC APIs, SDKs, and integration layers that enable AI systems to invoke engineering capabilities and return structured results. - Integrate AI systems with Keysight CSG engineering environments across design, simulation, emulation, physical measurement, test automation, and laboratory systems. - Define agent and tool contracts, structured schemas, validation interfaces, state models, and error handling patterns for reliable execution. - Design context, retrieval, memory, and persistence mechanisms to reason over engineering intent, design artifacts, simulation and emulation outputs, and measurement data.
What you'll need
- BS, MS, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field (or equivalent industry experience). - 5+ years of relevant experience building production software systems, AI platforms, distributed applications, or engineering tools, with ownership of system architecture. - Software engineering proficiency in Python and C++ or another production systems language. - Hands-on experience with LLM application development, tool-calling, agentic workflows, RAG, context management, or orchestration frameworks such as LangGraph or LangChain. - Experience architecting backend services, REST or gRPC APIs, SDKs, service integrations, and production software components. - Understanding of distributed systems, asynchronous execution, state management, concurrency, reliability patterns, and integration architecture.
Nice to have
- Experience integrating AI systems with engineering design, simulation, emulation, measurement, test automation, or lab instrumentation workflows. - Experience with Keysight or similar electronic design, validation, measurement, test, wireless, semiconductor, or telecom environments. - Experience with Model Context Protocol (MCP), Agent-to-Agent communication, structured tool protocols, or custom agent runtime interfaces. - Experience with vector databases, knowledge graphs, semantic retrieval, multimodal context, or document processing. - Experience with GPU-backed inference, model serving, prompt and model versioning, evaluation pipelines, and performance optimization for AI workloads. - Experience with Kubernetes, Docker, hardware-in-the-loop systems, digital twins, SCPI, VISA, or measurement automation.

How we counted: 64 open EDA/CAD Engineering (AI EDA Design) roles from 22 employers tracked in the SemiconductorJobs index, counted 23 Oct 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there — it is counted in the wider Physical Implementation family row.
