• Develop responsive, multi-page web applications using front-end frameworks such as React, Angular, and Vue.js.
• Design and manage relational and NoSQL databases, including writing complex SQL/PL-SQL scripts and working with databases like Oracle, DB2, MongoDB, and Cassandra.
• Develop and integrate RESTful and SOAP-based web services and APIs using platforms like MuleSoft or Apigee.
• Implement and manage continuous integration and continuous delivery (CI/CD) pipelines using tools like Jenkins, Maven, Gradle, and Bamboo.
• Mentor and provide technical guidance to a team of developers, ensuring high standards for code quality and software development lifecycle best practices.
• Participate in all phases of the software development lifecycle, from gathering requirements to deployment and maintenance, in both Agile and Waterfall environments.
• Provide subject matter expertise to solve complex technical challenges and support business partners.

Required Qualifications

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent experience.
• 12+ years of hands-on experience in Java/J2EE application development, with a focus on building business-critical software for large enterprises.
• Expertise in Java, J2EE, and the Spring Framework (Spring Boot, Spring MVC, Spring Security, etc.).
• Extensive experience with front-end technologies, including React, Angular, JavaScript, and HTML/CSS.
• Experience with cloud native architecture and development in either AWS, GCP, or Azure.
• Very strong experience with relational databases (Oracle, DB2, SQL Server) and NoSQL databases (MongoDB, Cassandra).
• Thorough understanding of Web Services and APIs, including SOAP/REST APIs and integration platforms like MuleSoft.
• Experience with message queuing systems like Kafka, Solace, or Active MQ.
• Proficiency with CI/CD tools such as Jenkins, Maven, and Gradle.
• Strong knowledge of software design patterns (MVC, DAO, etc.) and object-oriented programming concepts.
• Excellent communication, problem-solving, and mentoring skills.
• Familiarity with source control systems like Git and defect tracking systems.
• Experience with testing tools such as SoapUI or Selenium.
• Experience in managing App/Web servers/Containers like JBoss, Tomcat, Weblogic or Websphere.

Desired Qualifications

• Experience with healthcare and healthcare insurance solutions, including HIPAA healthcare data and transactions (e.g., X12, HL7 FHIR).
• Experience with Rule Engines like IBM ODM or ILOG JRules.
• Experience designing, developing, securing, and managing APIs via API Gateways and proxies using platforms such as MuleSoft or Apigee.
• Knowledge of in-memory caching solutions like Redis.
