Senior Staff Full-stack Engineer - FS Tech Architecture

Capital One•Plano, TX

About The Position

As a Staff Engineer at Capital One, you'll bring deep technical judgment to problems where the stakes are real. In Capital One Auto's innovation space, the "Garage," you're building and evolving the systems that power auto financing and servicing at national scale — loan origination, dealer-facing platforms, and the pipelines that keep millions of customers' loans accurate and available. A consistency bug or an unmaintainable design here isn't just technical debt — it's a loan that posts wrong, a dealer integration that breaks at the worst possible moment, or a system nobody can safely change two years from now. You'll work inside a fully cloud-native, AWS-based stack alongside engineers, ML practitioners, and product leaders across Capital One who expect you to reason rigorously about scale, failure modes, and long-term maintainability — not just ship working code. And because talent moves across Capital One, you're joining a company-wide community of technical experts, not just a single team's roster. Staff Engineers are expected to lead through technical contribution. You will operate as a trusted advisor for our key technologies, platforms and capability domains, creating clear and concise communications, code samples, blog posts and other materials to share knowledge both inside and outside the organization. You will specialize in a particular subject area, but your input and impact will be sought and expected throughout the organization.
