## About the Role

8+ years of software engineering experience, including at least 5 years developing enterprise-grade Java applications.

 * 3+ years delivering microservices and cloud-native solutions in complex enterprise environments.
 * Experience in large-scale commerce, retail, digital transformation, or platform migration programs.
 * Prior exposure to Salesforce Commerce Cloud, composable commerce, headless architecture, Contentstack, Constructor Search, or comparable ecosystems is preferred.
 * Should have experience on AI solutions

## Description

Design, develop, and modernize business-critical commerce capabilities as Catalyst migrates brand experiences from Salesforce Commerce Cloud to the Unified Digital Platform (UDP).
The engineer will own end-to-end feature delivery across backend services, APIs, integrations, React-based experiences, cloud deployments, test automation, and migration activities while ensuring alignment with UDP architecture standards and reusable platform patterns., * Transform legacy SFCC and custom business capabilities into modern Java and Spring Boot microservices.

 * Design reusable domain services for customer, catalog, pricing, order, payment, loyalty, and content capabilities.
 * Build scalable, secure REST APIs and participate in application decomposition, refactoring, and technical-debt reduction.

Front-end engineering:

 * Develop React-based composable storefront experiences using TypeScript, modern state-management patterns, and reusable components.
 * Enable brand-specific styling and customer journeys while maximizing adoption of shared UDP services and UI components.
 * Optimize accessibility, browser compatibility, page performance, reliability, and overall customer experience.

Integration engineering:

 * Build interfaces between UDP and retained enterprise platforms, including OMS, ERP, payments, loyalty, catalog, search, and content services.
 * Develop canonical models, provider interfaces, and brand adapters that isolate system-specific behavior.
 * Implement synchronous API and event-driven integrations using Kafka or approved messaging services.

Cloud and DevOps:

 * Build containerized applications using Docker and deploy workloads to Kubernetes or OpenShift environments on AWS.
 * Contribute to CI/CD pipelines, infrastructure configurations, release automation, environment validation, and operational readiness.
 * Implement logging, monitoring, distributed tracing, security controls, health checks, resiliency, and performance standards.

Migration, cutover, and quality engineering:

 * Execute data mapping, conversion, synchronization, reconciliation, migration rehearsals, cutover, and hypercare activities.
 * Create unit, component, API, integration, UI, and regression automation using JUnit, Mockito, Postman, and Playwright.
 * Investigate complex defects, complete root-cause analysis, and support rollback or roll-forward decisions during releases.
 * Participate in estimation, backlog refinement, design reviews, code reviews, demos, technical documentation, and sprint ceremonies.

Required Technical Skills:

 * Engineering foundation Platform delivery
 * Java 11/17+, Spring Boot, Spring Cloud, Hibernate/JPA React, TypeScript, JavaScript ES6+, HTML5, CSS3
 * REST APIs, microservices, DDD and common design patterns AWS, Docker, Kubernetes/OpenShift and CI/CD
 * Kafka/event streaming, API gateways and integration patterns Jenkins/GitHub Actions; Terraform preferred
 * Oracle/PostgreSQL/MySQL; NoSQL fundamentals JUnit, Mockito, Postman, Playwright and SonarQube
 * Secure coding, performance, resiliency and observability Git, Maven/Gradle and Agile engineering practices
