Job description
Full-stack Engineer 4
Do you love building and pioneering in the technology space? Do you enjoy solving complex business problems in a fast-paced, collaborative, inclusive and iterative delivery environment? At Capital One, you'll be part of a big group of makers, breakers, doers and disruptors who solve real problems and meet real customer needs. We are seeking Full-stack Software Engineers who are passionate about leveraging cutting-edge open source frameworks and emerging technologies. In this role, you’ll be at the forefront of driving a major transformation across Capital One.
About the Team
The Servicing, Business, and International team in Card Tech+ empowers our world-class talent to build technology that powers superior customer experiences and serves the unique needs of our business partners. From innovative servicing platforms to customized products for commercial clients, we leverage the power of data and machine learning to deliver high value solutions.
This team builds experience that agents can use to detect, investigate, and shut down card fraud as it happens and also allows customers to report fraud that they have encountered. Operating inside our Empath platform, we tackle high-stakes challenges like account takeovers, transaction fraud, and first-party fraud. Right now, we’re leveling up: transforming from rigid, pre-determined interfaces into a dynamic, configuration-driven intelligent workflow engine. If you want to design flexible, highly scalable systems that put bad actors out of business faster, this is where you belong. Our team uses Vue.js, Node.js (Fastify), Python, and AWS (Fargate, Lambdas) to build and deliver.

- Collaborate with digital product managers, and deliver robust cloud-based solutions that drive powerful experiences to help millions of Americans achieve financial empowerment
- Utilize programming languages like Java, Scala, Python, Go, Node.js, JavaScript and TypeScript, Open Source RDBMS and NoSQL databases, Container Orchestration services including Docker and Kubernetes, and a variety of AWS tools and services
- Provide technical leadership and direction across Agile teams, setting standards for design, development, and operational excellence
- Partner with architects to define service boundaries, integration patterns, and reusable frameworks
- Proactively identify areas for improvement, implementing targeted refactoring and contributing to efforts that reduce technical debt and enhance system performance
- Influence long-term technology strategy through evaluation of emerging tools and practices in a ‘you build it, you own it’ environment
