🎯 Your mission

  • Own and evolve the target architecture for core transactional platforms

  • Design scalable, resilient, and secure distributed systems

  • Define and govern microservices and event-driven architecture patterns

  • Lead architectural decision-making across multiple engineering teams

  • Ensure alignment with non-functional requirements including performance, availability, security, and compliance

  • Guide teams on clean architecture, Domain-Driven Design, and SOLID principles

  • Review solution designs and code from an architectural perspective

  • Partner with DevOps and platform teams on CI/CD, deployment, and runtime architecture

  • Drive cloud adoption and container-based delivery models

  • Identify technical risks early and define mitigation strategies

  • Support production readiness, operational stability, and incident prevention

  • Act as the technical escalation point for complex architectural challenges


🧭 You bring

  • Senior-level experience as a Software Architect or Lead Architect

  • Strong Java background (Java 8 or higher)

  • Extensive experience with Spring Boot, Spring Cloud, and enterprise frameworks

  • Proven track record designing high-throughput transactional systems

  • Deep understanding of microservices and distributed architectures

  • Experience with event-driven systems and messaging platforms

  • Strong API design skills including REST and security standards

  • Solid understanding of data consistency, concurrency, and fault tolerance

  • Experience working in regulated or high-availability environments

  • Strong communication skills and ability to influence senior stakeholders


Nice to have

  • Experience with gaming, lottery, or financial transaction platforms

  • Knowledge of security standards and compliance frameworks

  • Experience with performance tuning and capacity planning

  • Background in consulting or large enterprise delivery environments


💎 What we offer

  • Long-term engagement on a critical, high-impact platform

  • Opportunity to shape architecture at enterprise scale

  • Collaboration with senior engineers and decision-makers

  • Multinational, multicultural environment with complex technical challenges


Take ownership of architecture that truly matters and help build platforms where scalability, resilience, and reliability are non-negotiable 🌍
