About your role:
Fiserv builds the technology that powers payments and financial services for businesses and consumers.

Your work will help deliver reliable, scalable payment services and accelerate product delivery across the stack.
What you’ll do:
- Own one or more web services and drive feature development, bug fixes, refactors, and performance improvements from design through production.
- Design and build RESTful APIs and microservices that power mobile apps, payment devices, dashboards, and partner integrations.
- Partner with product and design to translate requirements into well-scoped, testable implementations that meet business goals.
- Lead end-to-end delivery for features: implement code, create automated tests, deploy, monitor, and iterate based on production telemetry.
- Collaborate with infrastructure and data engineers on data models, scaling strategies, and operational runbooks to support reliable services at scale.
- Participate in agile planning, code reviews, and cross-functional design discussions to raise code quality and align architecture decisions.
- Join a regular on-call rotation to rapidly address incidents and maintain system uptime.

- 8+ years of experience with relational databases such as MySQL, including schema design and query optimization.
- 8+ years of experience with cloud platforms and containerization (preferably Google Cloud Platform and Docker).
- 6+ years of experience with CI/CD and automated testing frameworks and tools (e.g., Jenkins, GitHub Actions, Cypress, Selenium).
- 6+ years of equivalent combination of educational background, related experience, and/or military experience.
Experience that would be great to have:
- Experience building high-volume transactional or e-commerce systems and familiarity with payment processing flows.
- Practical experience developing Android client applications or integrating mobile SDKs with backend services.
- Hands-on familiarity with observability tooling (e.g., Prometheus, Grafana, Stackdriver) and incident response practices.
- Knowledge of PCI DSS or other payments security standards and secure coding practices.
