Learn more about what we do. Our award-winning culture embraces a bold vision of where technology can take us and a passion for tackling challenging problems with industry-first solutions. We believe that when people feel a sense of belonging, they can be more creative, innovative, and thrive at all points in their careers. We are looking for a Machine Learning (ML) Engineer to join our industry-leading data and IP management product team to build the knowledge and intelligence layers of SOS AI, our AI platform serving the intersection between Electronic Design Automation (EDA) and AI/ML workflows. Responsibilities • Design and build low-latency hybrid retrieval (lexical, vector, graph, faceted) over large, heterogeneous data for on-premises, IP-sensitive deployments. • Develop the semantic insight layer: automated tagging, domain-aware metadata, and embeddings as first-class managed assets with version provenance. • Build the EDA-aware knowledge graph as organizational memory: entity and relationship inference, ontology evolution, versioning, and temporal queries. • Implement agentic memory and outbound MCP servers exposing retrieval, graph traversal, and lineage to external agents with access controls gatekeeping and full audit. • Engineer governance so access control propagates from source data through embeddings, graph nodes, retrievals, and agent responses. • Benchmark retrieval quality, embedding models, and LLMs against EDA use cases, selecting models per task under cost and latency constraints. • Collaborate with product, EDA tool teams and customers to translate semiconductor and RF workflows into requirements. Qualifications • MS or PhD in Computer Science, Electrical Engineering, or related field • 5+ years building production ML or data-intensive systems. • Demonstrated experience building RAG and knowledge graph systems in production (a must): ingestion, indexing, and retrieval pipelines. • Hands-on expertise with LLMs: embeddings, fine-tuning, prompt and context engineering, evaluation, and open-weights models for on-prem inference. • Strong command of vector databases, graph databases, and low-latency retrieval infrastructure at scale. • Experience with agentic memory management and the Model Context Protocol (MCP) or comparable agent-grounding interfaces. • Proficiency in Python and modern ML frameworks ( PyTorch , Hugging Face, etc..), with solid software engineering and API design practices. • ML applied to semiconductor applications, especially the RF and microwave industry, is highly valued. • Familiarity with data governance, access control, and provenance in IP-sensitive or regulated environments is a plus.
