About the role
Key responsibilities & impact- You will be embedded across one or more workstreams supporting digital payments engineering, with responsibilities that may include:
- 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.
- 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.
- 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.
Requirements
What you’ll need- 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.
- 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.
- 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.
