About the role

Capital One is seeking an AI Engineer 5 to advance AI foundations, LLM core and agentic AI across banking applications. You will collaborate with engineers, researchers and PMs to deliver production-grade AI systems, including training, inference, vector search and governance. The role emphasizes optimizing cost, latency, and throughput while guiding technical direction and mentoring senior engineers. A strong AI/ML background and hands-on cloud experience are essential.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
