Current Master's, AI Engineering Internship Program - Summer 2027

In this role, you will:

Partner deeply with a cross-functional team of research scientists, PMs, and engineers to prototype and ship AI-native products that reach millions of customers.

Research, prototype, and productionalize high-impact AI systems, including multimodal search, intelligent document processing, and autonomous agentic workflows that push the boundaries of current industry benchmarks.

Design and optimize the critical infrastructure of our AI stack—from fine-tuning pre-training pipelines and reinforcement learning to implementing inference optimization, robust guardrails and sophisticated evaluation frameworks.

Leverage a broad stack of technologies including AWS Ultraclusters, PyTorch, and leading-edge agentic frameworks. You’ll be empowered with top-tier developer tools like Claude Code and Windsurf to accelerate the path from concept to code.

Architect agentic workflows that go beyond simple chat—enabling AI systems to autonomously navigate tools, orchestrate multi-step reasoning, and integrate seamlessly with complex microservice environments.

The Ideal Candidate:

You are curious, love to build systems, and also share our passion to do it the right way. You want to work on problems that have not been attempted before and will help change banking for good.

You move fluently from reading a research paper to implementing it in production. You have a deep, intuitive grasp of the latest advances in agentic workflows and multimodal models.

You adapt quickly and thrive on bringing clarity to big, undefined problems. You love asking questions and digging deep to uncover the root of problems and can articulate your findings concisely with clarity.

You are deeply Technical. You possess a strong foundation in engineering and mathematics, and your expertise in hardware, software, and AI enable you to see and exploit optimization opportunities that others miss.

You excel at decomposing complex problems. You possess the judgment to decide where AI adds value and how to orchestrate AI workflows incorporating time-tested systems design principles, integrating both into a unified whole.
