Job Title

Technical Lead - Commerce Hub

About your role:

At Fiserv, we are committed to transforming financial services technology to deliver greater value for our clients. As a Technical Lead in our Payment Processing group, you will play a pivotal role in driving a key part of our modernisation program. This includes re-architecting critical systems toward microservices and an event-driven architecture, while shaping an engineering culture that embraces AI enabled ways of working. This is more than a coding role - it’s an opportunity to lead change, embed intelligent tooling and practices, and raise the bar for how we build, deliver, and scale next generation payment processing solutions.

What you’ll do:

• Own a major modernisation stream focused on transitioning to microservices and event-driven architectures.

• Design, build, and deliver high-quality, scalable software applications that strengthen Fiserv’s payment processing capabilities.

• Collaborate across functions - partnering with product, architecture, operations, and compliance teams - to translate business needs into technical outcomes.

• Leverage and extend our core technology stack (Java, AWS, Kafka, Kubernetes) to build secure, reliable, and performant solutions.

• Champion engineering excellence through code reviews, testing practices, and driving improvements in CI/CD pipelines.

• Mentor and uplift the team, sharing expertise and guiding junior engineers to adopt modern development practices.

• Act as a change agent, helping evolve our technology, processes, and mindset to align with modern software engineering principles.

• Drive initiatives from concept to production, balancing strategic modernization with near-term delivery needs.

Experience you’ll need to have:

• Proven track record of leading software development initiatives in complex, distributed environments.

• Strong proficiency in Java, with deep experience in modern frameworks and tooling.

• Hands-on experience with AWS services and cloud-native application design.

• Expertise in Kafka (or similar event streaming platforms) and understanding of event-driven patterns.

• Practical knowledge of Kubernetes and container orchestration.

• Familiarity with CI/CD pipelines and DevOps practices that accelerate delivery.

Experience that would be great to have:

• Previous experience in financial services or payments, understanding the unique performance, security, and compliance requirements.

• Hands-on involvement in legacy modernisation programs, particularly within mission-critical systems.

• A history of introducing new tools, frameworks, or practices that improved team delivery and product quality.
