Job Description
Seeking a Senior Java Developer to join our technology team. This is a full-stack role with an even split between middle-tier Java development and modern front-end development. Candidates must demonstrate genuine depth on both sides of the stack — this is not a backend role with incidental UI responsibilities.
Required Qualifications
5+ years of hands-on Java/J2EE enterprise application development, with demonstrated ability to speak to specific projects and technical decisions.
Back-End
· Core Java including multi-threading, Executor framework, and concurrency patterns
· Spring Boot, Spring MVC, Spring Security, Hibernate, MyBatis
· RESTful web services design and implementation
· Microservices architecture on AWS
· JBoss and/or Apache Tomcat application server deployment
· SQL design, stored procedures, and query optimization
· XML/XSLT, JSON
Front-End — candidates must demonstrate current, hands-on experience
· Angular version 14 or higher — component architecture, reactive forms,
RxJS, routing, and integration with Spring Boot REST APIs
· TypeScript, JavaScript (ES6+), HTML5, CSS3, AJAX
· JSP, JSTL
DevOps & Tooling
· GitHub Copilot in Agent mode — active use in development workflow required
· Git, Jenkins, Docker, Kubernetes
· Web application security best practices (OWASP, OAuth2, JWT)
Preferred Qualifications
· P&C insurance domain experience
· Performance tuning experience (JVM, database query optimization, front-end load performance)
· AWS certifications
