Hands-on experience with Microsoft Azure, Azure Kubernetes Service (AKS), and WebSphere Liberty or Open Liberty is essential.

The developers will collaborate with business stakeholders, architects, technical teams, and project leadership to support application modernization, system integration, data processing, troubleshooting, and continuous delivery.

Key Responsibilities

Translate business requirements and technical specifications into detailed programming specifications, application designs, and production-ready code.
Develop and maintain front-end interfaces, back-end services, database components, and RESTful APIs.
Design, implement, and enhance data pipelines, including data extraction, transformation, loading, validation, and integration activities.
Develop reusable, modular, maintainable, and testable software components using Java, Java EE, JavaScript, React, Angular, and related technologies.
Design and optimize relational database structures, SQL queries, data models, and application-to-database integrations.
Implement and maintain cloud-native solutions using Microsoft Azure, AKS, and WebSphere Liberty or Open Liberty.
Support application deployment, migration, modernization, and configuration across cloud, virtualized, and on-premises environments.
Implement automated build, testing, integration, and deployment processes using appropriate DevOps tools and practices.
Perform unit, integration, system, regression, and other relevant testing activities; investigate defects and verify corrective actions.
Troubleshoot application, database, middleware, integration, and deployment issues, providing technical support during implementation and post-deployment activities.
Apply secure coding practices and contribute to application security, cryptography, threat and risk assessments, and business impact analysis.
Ensure applications meet performance, scalability, reliability, accessibility, and maintainability requirements, including applicable AODA standards.
Develop and maintain technical documentation, application architecture artifacts, data models, test specifications, deployment procedures, and user documentation.
Participate in design walkthroughs, code reviews, technical discussions, and knowledge-transfer sessions.
Collaborate with business analysts, project managers, architects, QA specialists, database administrators, and other IT professionals throughout the SDLC.
Provide technical guidance and mentorship to junior developers while ensuring delivery commitments and project deadlines are met.
