We value collaborative problem-solving, pragmatic design, and a shared sense of ownership over what we ship. If you care deeply about code quality and want your work to have real-world financial impact, this role is for you. Responsibilities: • Write clean, testable, secure, maintainable, and extensible backend code across payment processing systems • Investigate and resolve complex bugs and production issues with precision and care • Work on non-trivial engineering problems that require deep evaluation of data, system behavior, and tradeoffs • Understand and improve application scalability and performance proactively • Contribute to technical design discussions and propose pragmatic solutions in line with team standards • Collaborate with Product Managers, QA, SRE, and business stakeholders to deliver high-quality outcomes • Support and participate in the hiring process by helping identify and engage strong engineering talent • Drive AI readiness and adoption — leverage Claude via AWS Bedrock for AI-assisted development, intelligent code review, automated documentation, and smart observability across payment workflows • Use AWS Bedrock's enterprise controls (IAM, CloudWatch, VPC, audit logs) to ensure AI usage remains secure, compliant, and fully observable within production environments
