Senior Software Engineer

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 . We encourage engineers to lead solutions end-to-end, mentor others, and continuously improve how we build and operate software. 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.

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
• This role includes participation in an on-call rotation, with on-call duties scheduled for one week out of every five weeks.

Experience:

• Significant commercial experience with modern Java 15 (We’re currently moving to 21. As a guide, multiple projects with 5+ years of experience. Proven experience designing, building and maintaining distributed systems and microservices)
• Deep understanding of Object-Orientated programming
• Familiarity with event-driven architectures or Domain Driven Design.
• Love to work using TDD
• Strong grasp of relational databases (PostgreSQL, MySQL) and data modeling.
• Solid understanding of cloud infrastructure (AWS preferred), containerisation, CI/CD, and Infrastructure-as-Code.
• Nice to have, but not critical, experience in fintech, payments, or other high-throughput/regulated domains.
• Most importantly, a desire to learn, grow and collaborate with an amazing team

• 100% remote, globally distributed team
• We value engineers that closely understand our customers and business
• High-impact role supporting real-time global payments
• Growth path toward Senior Engineer 2, Staff Engineer, or Engineering Manager
