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.

Requirements

• 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.
