And we have the leadership to help you get there. At CNA, we strive to create a culture in which people know they matter and are part of something important, ensuring the abilities of all employees are used to their fullest potential.\nAn individual contributor role that provides a high level of leadership and expertise in building Artificial Intelligence and Machine Learning (AI & ML) platforms and solutions for financial services and insurance. The role will be responsible for developing data into usable information to create automated analytics solutions.JOB DESCRIPTION:\nEssential Duties & Responsibilities\nPerforms a combination of duties in accordance with departmental guidelines:\nBuild, apply, and promote adoption of platform-wide standards, reusable design patterns, and golden-path templates that enable product and feature teams to build, deploy, and operate AI solutions safely and consistently.\nDrive end-to-end delivery of new platform capabilities, from technical discovery and design through prototyping, hardening, and full production rollout, with hands-on involvement at critical technical milestones to ensure quality and coherence.\nBuild and operationalize the core platform service catalog, including LLM gateway and routing layers, prompt lifecycle management, agentic orchestration frameworks, Retrieval-Augmented Generation (RAG) pipelines, vector stores, model registries, and rigorous automated evaluation infrastructure.\nBuild and maintain robust CI/CD and AIOps pipelines for AI systems, incorporating automated evaluation gates, model and data versioning controls, staged deployment promotion, and continuous cost and performance optimization guardrails.\nImplement enterprise-grade multi-agent and single-agent workflow patterns for high-value business use cases, following clear standards for orchestration design, state and memory management, tool and API integration, and safe autonomy controls, including human-in-the-loop approvals, permission scoping, and comprehensive audit trails.\nDesign and implement knowledge grounding systems, including hybrid retrieval strategies, semantic reranking, ontology-driven entity modeling, and knowledge graph integration, to measurably improve AI output accuracy, explainability, traceability, and readiness for regulatory audit.\nEmbed responsible AI and compliance-by-design principles across the platform, covering data privacy protections, enterprise secrets management, granular access controls, output leakage prevention, and model risk governance practices aligned to enterprise and regulatory standards.\nParticipate in code and design reviews, and contribute to testing, documentation, and operational readiness.\nMay perform additional duties as assigned.\nReporting Relationship\nTypically Director or above\nSkills, Knowledge & Abilities\nDeep AI platform and AIOps engineering expertise, with hands-on experience building, deploying, and operating shared AI platform capabilities such as model serving layers, LLM gateway and proxy services, prompt registries, vector databases, and automated evaluation harnesses at enterprise scale.\nProven agentic system design capability, with hands-on experience building multi-agent and single-agent workflow systems using orchestration frameworks such as LangGraph and Google ADK, including tool and function calling patterns, state and memory persistence strategies, and robust safe autonomy controls.\nApplied GenAI depth spanning LLM solution architecture patterns, model selection and routing strategies, advanced prompt engineering techniques, fine-tuning and RLHF tradeoffs, and production-grade RAG and hybrid retrieval system design and optimization.\nStrong cloud-native and distributed systems skills, with deep GCP expertise across Vertex AI, Cloud Run, GKE, Pub/Sub, and BigQuery, and a solid command of API and service-based design, event-driven architecture, and high-availability and fault-tolerant system patterns.\nKnowledge grounding and semantic layer proficiency, including experience building canonical ontology and entity models, designing vector search and hybrid retrieval pipelines, integrating knowledge graphs, implementing reranking strategies, and establishing citation and traceability mechanisms that support explainability and compliance.\nSolid AIOps and platform reliability engineering experience, including CI/CD pipeline design for AI systems, automated evaluation and quality gates, model and dataset versioning, production monitoring and observability, reliability engineering practices, and systematic cost-performance optimization.\nPractical responsible AI and security expertise, with experience implementing enterprise AI governance frameworks, model risk management practices, PII and data privacy controls, audit and event logging, and compliance-by-design patterns suited to regulated industries.\nStrong SDLC and hands-on engineering fundamentals, including Python proficiency, architectural and code review practices, comprehensive testing strategies for AI systems, technical debt management, refactoring discipline, and operational readiness standards.\nFamiliarity with Scaled Agile (SAFe), including contributing to Enabler Epics and PI planning.\nStrong communication skills, with the ability to collaborate with engineers, product partners, and business stakeholders, negotiate technology tradeoffs, mentor junior engineers, and explain technical concepts clearly to non-technical audiences.\nEducation & Experience\nBachelor’s degree in Computer Science, Software Engineering, Information Technology, or equivalent required; Master’s degree in AI, Machine Learning, Data Science, or a related discipline strongly preferred.\n8+ years in software engineering and technical delivery, including work on large-scale, distributed enterprise systems across the full SDLC, from inception through production operations.\n5+ years hands-on designing, delivering, and operating AI/ML or GenAI platform capabilities in production, with measurable outcomes in quality, reliability, and developer adoption.\nStrong Python proficiency and deep practical GCP experience (Vertex AI, GCP Agent Builder, and Gemini), with the ability to do hands-on technical work as part of the engineering team.\nPrior experience in regulated industries (insurance, financial services, or healthcare) strongly preferred, given stringent governance, auditability, and model risk management requirements.\nConsulting or enterprise delivery background is a plus, bringing structured problem-solving and stakeholder management.\n#LI-KJ1 #LI-HYBRID\nIn certain jurisdictions, CNA is legally required to include a reasonable estimate of the compensation for this role.
