Sepenuh Masa Full-Stack Software Engineer Jobs, in NHN KCP GLOBAL - Maukerja

Role Description

• Design, build, and maintain backend services and APIs that process payments and move money reliably and securely.
• Develop event-driven workflows using messaging and asynchronous patterns such as transactional outbox, queues, and worker/saga processes.
• Model and evolve relational data with disciplined, versioned schema migrations.
• Contribute to user-facing surfaces — embedded checkout SDKs, hosted payment elements, and internal operator tooling.
• Write, review, and maintain infrastructure-as-code, and help manage cloud resources, networking, and deployment pipelines.
• Build in observability from the start — metrics, dashboards, and alerting — and participate in keeping production healthy.
• Uphold security and compliance requirements (PCI-DSS) across the systems you touch, including encryption, secrets handling, and audit controls.
• Collaborate with product, security, and operations to ship features through CI/CD with appropriate testing and review.

Technologies you'll work with

Our stack is pragmatic and modern. You don't need every item below on day one — depth in several backend and infrastructure areas matters more than breadth.

• Backend: Java with Spring Boot, plus TypeScript / Node.js services.
• Data: PostgreSQL with Flyway migrations; managed cloud databases.
• Eventing & messaging: Apache Kafka, transactional outbox, dead-letter queues, and schema contracts (JSON Schema / Avro).
• Cloud & infrastructure: Google Cloud Platform — GKE (Kubernetes), Cloud Run, Cloud SQL, Cloud KMS, Secret Manager, networking (VPC, load balancing).
• Infrastructure-as-code & CI/CD: Terraform, Docker, GitLab CI, with IaC security scanning (Trivy, Checkov, tfsec).
• Observability: Prometheus, Grafana, and Micrometer-based instrumentation, with PagerDuty / Slack alerting.
• Frontend & SDKs: JavaScript-based embedded SDKs and web UI; mobile and e-commerce platform integrations.

What We're Looking for

• 3–5 years of professional software engineering experience, with a clear backend emphasis.
• Strong skills in a JVM language (ideally Java/Spring Boot) and/or Node.js/TypeScript, and solid command of relational databases and SQL.
• Experience designing and operating services in the cloud — containers, Kubernetes, or serverless runtimes.
• Hands-on exposure to infrastructure-as-code (Terraform) and CI/CD pipelines.
• A working understanding of asynchronous and event-driven architectures.
• Care for production quality: testing, observability, secure coding, and a security- and reliability-first mindset.
• Clear communication and the ability to collaborate across product, security, and operations.

Nice to Have

• Experience in payments, fintech, or other regulated, high-compliance environments (e.g. PCI-DSS).
• Familiarity with Kafka or similar streaming platforms and outbox/saga patterns.
• Hands-on work with Cloud KMS / envelope encryption, secrets management, or cardholder-data isolation.
• Experience building or maintaining client-facing SDKs (web, mobile, or e-commerce plugins).
• Comfort with Prometheus/Grafana observability and on-call practices.
