Java Software Engineer II

Are you ready to write your next chapter?

Make your mark at one of the biggest names in payments. We’re looking for a Java Software Engineer II to join our ever-evolving NAP engineering team and help us unleash the potential of every business.

What you’ll own as the Java Software Engineer II

This role is well-suited for someone with professional development experience who enjoys structured, detail-oriented work and prefers a steady and predictable environment over fast-paced, constantly evolving projects. You will focus on maintaining and enhancing key components of our cost and rating engines, particularly around fees and interchange costs. The work involves Java-based coding with consistent, repeatable patterns, ensuring accuracy, compliance, and reliability in transaction processing.

If you enjoy analytical work, have patience for structured coding, and perhaps bring a background in QA with an interest in transitioning into a more development-focused role, this position could be a great fit.

A Software Engineer is accountable for:

• Development and maintenance of Java-based components in the cost and rating engines, in accordance with the requirements provided.

• Updates and enhancements to transaction cost and fee calculation logic, based on business and system requirements.

• Adjustments to data mappings, flows, and enrichment rules to ensure correct cost determination.

• Supporting fee evaluation processes to deliver accurate, consistent outputs.

• Collaboration with analysts and testers to confirm quality and compliance.

• Using GitHub and Jenkins as part of your day-to-day development workflow.

• Clear documentation of updates for long-term maintainability.

What you'll bring

• Over 4 years of experience in Java development with a steady, consistent coding style.

• Strong analytical thinking and attention to detail.

• Comfort working with GitHub (branches, merges, pull requests) and Jenkins (build pipelines).

• Familiarity with databases (Postgres preferred, or other relational databases is a plus).

• Some familiarity with agile frameworks and methodologies (Scrum, Kanban, SAFe).

• Some background in QA is a plus, especially for candidates looking to transition into a development role focused on writing and configuring code.

• Strong communication skills – able to collaborate with analysts, testers, and teammates clearly and effectively.

• An appreciation for accuracy, predictability, and consistency in software development.

• Ability to work independently on well-defined tasks, while being a reliable team contributor.

Why you'll love this role

• Work on structured, predictable coding tasks where accuracy matters most.

• Apply your experience in a steady, long-term project environment without the churn of shifting priorities.

• Know that your work directly improves transaction accuracy and compliance.

• Join a collaborative team that values experience, reliability, and thoroughness.

• Thrive in a role designed for engineers who prefer a stable, consistent career path.
