What’s special about our payment platform

• Built for resilience: a fault-tolerant platform where payments keep flowing even when parts of the system or external partners fail

• Integrations: international partners and domestic Philippine payment rails

• Money-movement flows: cash-in, cash-out, bill payments, loan disbursement and repayment, and more

• Platform approach: one platform serving multiple internal products and teams, with shared APIs, SDKs, and reusable building blocks

• Architecture: Kotlin/Spring Boot microservices, Kafka, relational databases, and durable workflow orchestration for long-running payment processes

• Reliability by design: idempotency, retries and timeouts toward unreliable external partners, full audit trail

• Compliance: regulated environment (BSP), with security and fraud checks built into the flow

What you’ll do

• Develop scalable microservices on the JVM with Spring Boot, as part of a team building platform solutions for our banking product.

• Design payment services with a focus on DDD, eventual consistency, and resilience to partner and infrastructure failures.

• Work with product, QA, security, and operations to release changes under agreed engineering standards.

What you’ll own

• Own the design, build, and maintenance of software components supporting the Core Engineering team.

• Design and evolve payment flows end to end: processing, routing, status handling, refunds/reversals.

• Integrate new payment providers, banks, and partner channels, and handle their failure modes gracefully.

• Build and maintain scalable, reliable APIs and services, and contribute to internal SDKs and frameworks that let product teams launch new payment use cases quickly and safely.

• Investigate payment incidents (stuck, duplicated, or inconsistent transactions) and make the system self-healing.

• Translate functional requirements into technical solutions and maintainable implementations.

• Contribute to code and configuration reviews.

What makes you a strong fit

• 3+ years of software development on the JVM; good knowledge of Kotlin is an advantage

• Experience with Spring Boot in a microservice environment

• Experience with domain-driven design and eventual consistency

• Experience with payments, banking, or other transactional/financial systems (payment platforms, PSP integrations, wallets, ledgers)

• Solid understanding of idempotency, distributed transactions, retries, and timeouts in money flows

• Track record in an agile setup with continuous deployment and delivery

• Experience with containerization and orchestration in a cloud environment (Docker and Kubernetes preferred, AWS preferred)

• Experience with, and enjoyment of, continuous knowledge-sharing within the team

• Nice to have: Kafka, workflow engines, ISO 20022
