Senior Java Engineer (Commerce Platform) for Cebu-onsite

We are looking for a Senior Java Engineer to take ownership of the core commerce and account management platform that powers our US game portfolio. This is a critical, high-impact role: you will be maintaining the backbone application that processes transactions and manages player identities across PC, PlayStation, Xbox, Nintendo, and Steam.

You will be the primary engineering lead in your time zone, working autonomously to stabilize, secure, and modernize a complex legacy platform. This role is ideal for an engineer who enjoys high-level problem solving—specifically, taking a robust, established application running on Java and migrating it to modern infrastructure and security standards.

About the Role

• Platform Modernization: Lead the effort to update core libraries and frameworks to improve security and performance.
• Database & Cloud Migration: Architect and execute the migration of services from Google Cloud Platform (GCP) and assist in the database migration from MSSQL to PostgreSQL.
• Feature Engineering: Implement new critical features, including Single Sign-On (SSO) integrations with third-party providers.
• Platform Integration: Maintain and improve API integrations with major gaming platforms (Steam, PlayStation, Xbox, Nintendo).
• Full-Stack Maintenance: Maintain the backend logic as well as the frontend implementation using FreeMarker (.ftl) templates and Spring Web Flow.
• Autonomy & Communication: Work independently as the technical anchor in your region, collaborating remotely with US-based leadership via Jira and GitLab.

• Expert Java Proficiency: Deep experience with Java development and maintenance.
• Framework Experience: Hands-on experience with Spring (specifically Spring Web Flow) and Apache Struts.
• Database Skills: Strong experience with MSSQL; familiarity with PostgreSQL or database migration projects is highly preferred.
• Server-Side Templating: Experience with FreeMarker (.ftl) or similar template engines.
• Containerization & Orchestration: Strong experience deploying and managing applications on Kubernetes (K8s).
• Build & Messaging: Proficiency with Maven for build automation and AMQ (ActiveMQ) for messaging.
• Experience with OAuth2, OIDC, or SAML for implementing SSO.
• Experience with payment gateway integrations or e-commerce platforms.
• Experience migrating legacy monoliths to microservices or modern cloud infrastructures.

Soft Skills:

• Self-Starter: Proven ability to work autonomously with minimal supervision; you are comfortable owning the technical direction of a project in your time zone.
• Resilience: You aren't afraid of "spaghetti code." You enjoy the challenge of untangling complex legacy dependencies to create a stable, modern system.

• Join a diverse, international team of colleagues from over 30 countries, where shared goals and a variety of perspectives make us stronger
• Take on meaningful challenges that come with real responsibility and plenty of room to grow in our dynamic environment 
• Dress comfortably! We keep things casual here, so you’re free to wear what feels right for you
• Benefit from mandatory government contributions, including SSS, PhilHealth, and Pag-IBIG, for your peace of mind
• Make work more fun with exciting company events like our annual Halloween party, Christmas celebration, and team outings
• Recharge with an additional 3 Wellness days throughout the year, next to the statutory vacation days and public holidays
• Enjoy health insurance upon regularization to keep you and your loved ones protected
• Receive your 13th Month Pay and Overtime Pay as part of a fair and rewarding package
