Requirements

5+ years of professional software engineering experience, with demonstrated expertise across both frontend and backend development
Proficiency in modern frontend frameworks, particularly React (TypeScript preferred), with a strong grasp of state management, component design, and web performance
Strong backend engineering skills in one or more of: Java, Node.js, Go, or Python, with experience building production-grade, distributed services
Deep experience designing and consuming RESTful APIs; familiarity with event-driven architectures (e.g., Kafka, SQS)
Solid understanding of relational and NoSQL databases (e.g., PostgreSQL, DynamoDB) and data modeling best practices
Experience working in AWS or similar cloud environments; comfort with containerization (Docker, Kubernetes)
Proven ability to lead technical design, write clear technical specs, and drive consensus across engineering and product stakeholders
Strong understanding of software engineering fundamentals: object-oriented design, design patterns, testing strategies (unit, integration, E2E), and CI/CD
Experience with Agile/Scrum delivery practices

Nice To Haves

Comfortable operating in an environment where the roadmap evolves quickly, requirements are sometimes ambiguous, and the decisions you make today will form the foundation others build on for years. You default to action, communicate trade-offs clearly, and know when to move fast vs. when to slow down and get it right
Familiarity with PCI-DSS compliance requirements and security best practices for financial data
Contributions to platform architecture, developer tooling, or engineering process improvements
Familiarity with integrating LLM-powered features or AI-driven services into production applications - whether for personalization, fraud signals, customer support automation, or intelligent recommendations - and an interest in exploring how these capabilities can enhance the credit card and rewards experience
Actively using AI coding tools (e.g., GitHub Copilot, Cursor, Claude) to accelerate delivery and improve code quality; thoughtful about where AI assistance adds leverage and where human judgment is non-negotiable
Proven ability to pivot between problem domains, pick up unfamiliar technologies quickly, and contribute meaningfully across layers of the stack as team and product needs shift. You don't need a fully defined lane to do great work
If you possess some of these qualifications but not all of them, we still encourage you to apply!
