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
