This role offers a rare opportunity to work hands‑on with cutting‑edge large language models (LLMs) and emerging AI architectures while helping to shape the foundations of enterprise‑scale AI adoption. You’ll design and implement frameworks that make advanced AI capabilities widely accessible across teams — enabling improved knowledge retrieval, intelligent process automation, and enhanced decision support. You’ll collaborate closely with Front Office Technology, Quant Research, and business teams to develop robust AI systems that align with the firm’s strategic innovation goals.
