Sr Engineer - Software Development, Onsite

ESSENTIAL FUNCTIONS

• Lead the development and optimization of distributed microservices powering core retail and e-commerce platforms, specifically focusing on cloud-native, "headless" commerce implementations.
• Architect high-performance, stateless services for critical digital customer touchpoints, including shopping carts, product catalog indexes, and promotional calculation engines.
• Implement and extend critical retail functionalities, including real-time Global Inventory Visibility, complex fulfillment sourcing rules, and customized checkout/order routing pipelines.
• Design and build high-throughput integration flows between digital commerce platforms and enterprise systems (ERP, WMS, POS, and Payment Gateways) using a mix of RESTful APIs and asynchronous event-streaming.
• Orchestrate tokenized digital checkout systems, credit card vaulting integrations, and fraud-detection touchpoints. Secure end-to-end user transactions while maintaining strict PCI-DSS compliance standards.
• Architect systems to absorb extreme traffic concurrency and volume spikes during peak e-commerce sales events (e.g., Black Friday, Cyber Monday, or flash promotions).
• Drive the containerization of core retail services and cloud infrastructure using Docker and Kubernetes (AKS/EKS/OpenShift).
• Provide expert guidance on performance tuning (JVM heap settings, thread pool management), high availability, and fault-tolerant circuit breaker patterns (e.g., Resilience4j).
• Work with Product Managers and business stakeholders to translate complex digital commerce and supply chain requirements into lean, high-performing technical designs.
• Perform code reviews, establish enterprise coding standards for Java/Spring Boot, and mentor engineers in distributed systems design best practices.
• Lead post-incident reviews and drive systemic remediation and reliability improvements.
• Author and maintain high-level architectural documentation and technical standards.
• Mentor Engineers and Associate Engineers; set the technical bar for the organization.
