Key Responsibilities • Design, build, and evolve core frameworks and reusable platform components. • Perform hands-on coding for technology upgrades and migrations (Java/Spring/Jakarta/Tomcat and related platform components). • Own and drive large-scale modernization initiatives across services and shared libraries. • Build and evaluate POCs to assess new technologies, patterns, and platform capabilities. • Resolve complex technical issues across frameworks, distributed services, and integration layers. • Ensure implementation alignment with platform and enterprise architecture. • Define, review, and enforce coding standards, framework usage policies, and technical guidelines. • Mentor architects, tech leads, and engineers; guide design and code quality decisions. • Drive adoption of emerging technologies including AI-assisted development, cloud-native tooling, and observability practices. • Collaborate with architecture, product, and engineering stakeholders for execution and delivery alignment. Essential Experience Java & Backend • Strong Java proficiency across mixed runtimes (legacy and modern), with migration ownership toward modern LTS baselines (JDK 11+, preferably JDK 17). • OOP concepts, SOLID principles, and design patterns. • Spring Framework, Spring Boot, Spring MVC, and Spring Security. • RESTful API design and implementation. • JPA and Hibernate. API & Integration • Strong API governance and specification experience using Swagger/OpenAPI. • Experience with event-driven architecture and messaging patterns: Kafka producers/consumers, event contracts, serialization formats (JSON, Avro). • Strong validation and business-rule enforcement patterns in API and service layers. • Security and authentication implementation including OAuth2, JWT, and API security best practices. Data & Schema • Hands-on No-SQL and relational database experience (PostgreSQL preferred; MongoDB/Cassandra exposure is valuable). • Strong database schema evolution practices using versioning/changelog approaches (Liquibase). Platform & Delivery • Strong experience in framework/platform-level development (not only feature-level application coding). • Proven experience in migration and upgrade programs across core platform components. • Experience with application container runtimes and deployment packaging patterns (Tomcat, containerized deployments). • AWS ecosystem exposure (preferred). • Docker containerization. • CI/CD pipelines with Jenkins and Git-based workflows. • Kubernetes/EKS and Helm-based deployment patterns (preferred). Leadership & Practices • Strong debugging, performance analysis, and production problem-solving capabilities. • Experience working in Agile development environments. • Strong communication, cross-team collaboration, and technical leadership capability. • Proficiency with AI-assisted development tools (e.g., GitHub Copilot or similar) for productivity, code quality, and accelerated delivery. Good to Have • Front-end ecosystem awareness in JavaScript/TypeScript-based environments. • Observability tooling and SRE-aligned engineering practices. Technology Landscape This role spans two product platforms: CRS • Java backend (custom IoC/DI framework, Tomcat WAR deployment, Kafka clients, AWS SDK). • Jakarta XML Bind, Swagger/OpenAPI, PostgreSQL, JWT/OAuth2 (AWS Cognito). • Ember.js / TypeScript frontend with Webpack build tooling. • AWS-native CI/CD (CodeBuild, CodePipeline, CloudFormation, ECR). Distribution Gateway • Java 17, Spring Boot, Spring MVC, Spring Security. • Kafka event-driven architecture (producers/consumers, Avro/Glue-Avro serialization, configurable event topics). • Springdoc/OpenAPI, Swagger UI, RESTful APIs. • JPA/Hibernate, PostgreSQL, Liquibase-managed schema evolution. • Quartz/custom scheduler framework and @Scheduled jobs. • Multi-tenant datasource/filter/security patterns. • Dockerized builds, Jenkins CI/CD pipelines, AWS ECR, Helm deployment assets.
