Job description

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 WPG team to help us unleash the potential of every business.

What you’ll own as the Mid-Level Java Software Engineer

You will be working on our worldwide payment gateway (WPG): one of the largest-by-volume global payment platforms in the world, focusing intensively on robustness, security, and capacity that can process over 800 transactions every second and exceeding 10 million successful payments every day. 

We use the SAFE framework so we get together as a team every 3 months to review requirements, design a solution, and commit to a plan to deliver it. With the support of the teams' principal engineer, you will pick-up challenging work from the plan that needs your proven software skills to deal with the more complex problems. As one of the team's authorised gating code-reviewers, you will support and pair with other engineers in the team to grow the team’s capabilities, and ensure we are shipping quality changes.

  • Develop changes in Java and (PL)SQL to an ecommerce payments gateway.

  • Review payment processing business processes, analyse production data, walk the Product code, and review payments-industry spec documents to scope and specify the work.

  • Partner with the test engineers to help scope the test coverage and approach, and you may need to contribute to the automated integration and system tests.

  • Design a rollout and monitoring approach for features to ensure it works as expected.

What you'll bring

  • Experience delivering software to solve complex business problems

  • Strong Java knowledge (4+ years)

  • OOP design patterns and SOLID development principles

  • Ability to write code interacting effectively with large databases

  • Database systems knowledge ideally SQL-based Oracle, or similar

  • Experience with very large code bases and version control systems

It’s a bonus if you have

  • Knowledge of financial services industry

  • Familiarity with agile frameworks and methodologies (Scrum, Kanban, SAFe)
