The titles and summaries point strongly toward platform and infrastructure work rather than standalone model research. Most postings, concentrated at Capital One, involve designing, developing, and deploying components for large-scale generative AI systems: foundation model training pipelines, LLM inference and optimisation, guardrails, and vector database integration. Agentic AI patterns and an internal platform layer called MLX appear repeatedly in Capital One's titles. A Senior Lead AI Engineer (LLM Gateway, FM Hosting) role focuses specifically on inference infrastructure, while the Senior Lead AI Engineer (GenAI Platform Services, Agentic) and Agentic Platform variant emphasise software components for a shared GenAI platform. The Senior Manager, AI Engineering posting adds people leadership and build-versus-buy decision-making. Figure and the other employers on the page are represented by fewer postings, and their focus areas are not fully captured in the sample summaries.
Python and PyTorch appear in the clear majority of postings, and cloud platforms AWS, GCP, and Azure are each mentioned in roughly two-thirds. Evaluation, A/B testing, and publications are also frequent mentions, suggesting roles that extend beyond prototyping into rigorous validation work. C++ and Java appear alongside Python in many descriptions. These counts reflect mentions in job descriptions across all postings on this page, not formal requirements, and the sample is small enough that one employer's volume can skew any figure noticeably.
Every posting on this page is listed as on-site; none are stated as hybrid or remote. Several Capital One sample summaries name locations beyond San Jose — Cambridge, McLean, and New York are mentioned in individual postings — so candidates should check each listing for which office or offices a specific role is tied to. No postings state work-from-home eligibility. Whether any flexibility exists beyond what is advertised is not stated in these postings.
