Backend Engineer (Junior to Mid-Level)

Build and ship backend services: Design, develop, test, and maintain Java-based microservices that run our payment platform. Contribute to features across the payment lifecycle, including acquiring, clearing, settlement, and ledger accounting.

Protect user funds: Help build and improve reconciliation jobs, exception-handling flows, and monitoring that keep every transaction accurate and every peso accounted for.

Integrate with partners: Work on integrations with banks, local payment methods, card networks, and international payment partners. Along the way you'll learn how multi-currency and FX flows work.

Use AI in your daily work: Use AI-assisted development tools (e.g., code assistants, AI-driven testing, and debugging) to work more productively. Help explore and prototype AI-powered features and internal tools.

Improve reliability and performance: Troubleshoot production issues, write clean and well-tested code, and help make our systems more available, scalable, and efficient.

Collaborate across teams and regions: Work closely with product, risk, finance, and compliance, as well as Mandarin-speaking engineering and business teams, to deliver secure and compliant solutions.

1–5 years of professional backend development experience. Strong fresh graduates with solid internship or project experience are welcome to apply.

Hands-on experience with Java (Spring Boot preferred). Experience in other backend languages is a plus if you're willing to work mainly in Java.

Familiarity with microservices architecture, RESTful APIs, and relational databases (e.g., MySQL, PostgreSQL).

A strong interest in AI, such as regularly using AI coding tools, experimenting with LLMs or AI APIs, or building AI-powered side projects.

Proficiency in Mandarin Chinese (spoken and written) is required. You'll work regularly with Mandarin-speaking teams and stakeholders. Business-level English is also required.

A good grasp of computer science fundamentals: data structures, algorithms, and basic distributed systems concepts.

Strong problem-solving skills, ownership, and eagerness to learn.

Exposure to fintech, payments, banking, e-wallets, or crypto.

Experience with message queues (e.g., Kafka, RabbitMQ), caching (e.g., Redis), or containerization (Docker, Kubernetes).

Understanding of transaction consistency, idempotency, or reconciliation concepts.

Experience with cloud platforms (AWS, GCP, or Alibaba Cloud).
