Role Description We are seeking a Senior Software Engineer to join a high-impact digital payments modernization program supporting the integration of a major card network into one of the largest financial institutions in the United States. This is a hands-on engineering role at the intersection of legacy and modern infrastructure, where you will contribute to both the reliability of mission-critical payment systems today and help shape the architecture that will power them tomorrow. You will work across scalable backend services, performance testing frameworks, and application engineering — with real opportunity to grow your skills on modern cloud-native technologies as the program evolves. WHAT YOU'LL DO - Scalability, Performance Testing & Validation - Design and execute enterprise-grade performance testing strategies for payment processing services, defining frameworks, tooling, and success criteria from the ground up. - Identify performance bottlenecks across legacy and modern service layers and drive measurable improvements through analysis and targeted optimization. - Instrument and validate services running on Java, Oracle, Tomcat, and WebSphere as well as modern workloads running on PostgreSQL and OpenShift. - Collaborate with backend engineers to ensure scalability requirements are met across all environments prior to release. - Translate performance findings into clear recommendations for engineering leads and stakeholders. - Application Engineering - Build and maintain full-stack backend services supporting card network integration, working primarily in Java with PostgreSQL and OpenShift Container Platform (OCP). - Contribute to application modernization efforts, migrating and re-platforming services from legacy infrastructure to cloud-native environments. - Leverage AI-assisted development tooling (including GitHub Copilot) to improve development velocity and code quality. - Participate in code reviews, architectural discussions, and cross-team technical planning sessions. - General Engineering - PCI data purging pipelines and event-driven architecture patterns including token removal and event consumption. - Work with event-driven services running on OpenShift and Oracle and PostgreSQL backends to support data lifecycle and compliance requirements. - Serve as a flexible, senior contributor across teams where engineering depth and experience are needed most. Qualifications - 5+ years of professional software engineering experience, primarily in Java. - Strong working knowledge of relational databases — Oracle and/or PostgreSQL required. - Experience deploying and operating services in containerized environments (OpenShift, Kubernetes, or equivalent). - Familiarity with legacy enterprise application servers — Tomcat and/or WebSphere experience a plus. Requirements - At least one enterprise-level performance testing engagement — defining strategy, selecting tooling, executing tests, and presenting findings. - Experience with performance profiling, load testing, and bottleneck resolution in high-throughput, distributed systems. - Ability to design logical, streamlined test frameworks from scratch and operate with minimal guidance. - Background in digital payments, card processing, or financial services technology strongly preferred. - Understanding of PCI compliance requirements and secure data handling practices. - Familiarity with event-driven architecture patterns and OpenShift-based eventing. - Demonstrated ability to work effectively in large, matrixed program environments with multiple teams and stakeholders. - Strong written and verbal communication skills; able to translate technical complexity for non-technical audiences. - Comfortable operating in environments with evolving requirements and ambiguity. Benefits - Competitive compensation. - Professional development opportunities. - Flexible work arrangements.
