Description

At Paymentology, we’re building the global payments platform of the future. Our mission is to empower banks, fintechs, and innovators with modern, scalable, cloud-first issuing and processing solutions. As a fully distributed organisation operating across 60+ countries, we move fast, think globally, and build technology that supports millions of transactions daily.

Our Engineering culture values autonomy, excellence, ownership, and curiosity.

If you’re excited by solving complex global payments challenges and enjoy working with smart, kind, mission-driven people — this is the place for you.

What you get to do:

We’re looking for a Senior Software Engineer to design, build, and scale Java backend services that power our global payments infrastructure. You’ll lead end-to-end delivery, contribute to technical strategy, and help raise the engineering bar across the organisation.

Lead the design and development of backend services, distributed systems, and APIs.
Own features end-to-end (architecture, coding, testing, observability, and deployment).
Write clean, maintainable, well-tested code, following engineering best practices and test-driven development.
Break down complex technical work into manageable chunks
Work in a collaborative, cross functional, agile team environment
Mentor associate and mid-level engineers, fostering a culture of technical excellence
Identify, document, and deliver technical improvements (performance, reliability, scalability).
Participate in incident response and support rotations
