You will build reliable Java applications, APIs, and platform services that simplify how application teams provision, configure, validate, and operate enterprise hosting platforms. This role is ideal for a hands-on developer who writes clean, testable code, understands the operational demands of large-scale server environments, and treats quality, security, maintainability, and production readiness as core engineering responsibilities. You will lead by example across analysis, design, development, testing, deployment, and support. You will create modular Java and Spring Boot services, define automated test strategies with QA partners, enforce code-quality standards in CI/CD, review designs and pull requests, resolve defects, and use production feedback to improve reliability. You will also develop Ansible automation where needed to connect these services with application and web server operations. In this role, you will: Design, develop, test, and maintain enterprise Java applications and Spring Boot services that support application and web server platform capabilities. Build secure, versioned REST APIs for provisioning, configuration, deployment governance, certificate management, validation, and capacity workflows. Apply object-oriented design, SOLID principles, design patterns, exception handling, concurrency, dependency management, and performance engineering to produce reliable and maintainable code. Create comprehensive automated tests using tools such as JUnit, Mockito, REST Assured, and test containers, covering unit, component, integration, API, regression, and negative scenarios. Partner with QA engineers to define acceptance criteria, test plans, test data, environment needs, traceability, release validation, and defect-resolution strategies. Integrate build, test, security, code coverage, static analysis, and deployment controls into CI/CD pipelines using Maven or Gradle and enterprise delivery tooling. Use code reviews, quality metrics, observability, root-cause analysis, and production feedback to prevent defects and continuously improve software reliability. Develop reusable, idempotent Ansible roles and collections to automate server installation, configuration, JVM tuning, certificate operations, patching, compliance, and policy enforcement. Build self-service capabilities that allow development teams to request server instances, deploy applications, configure routing, request certificates, manage JNDI resources, and consume platform metrics. Participate in Agile planning, estimation, demonstrations, retrospectives, technical design reviews, release readiness reviews, and production support. Mentor engineers in Java development, automated testing, secure coding, code review, troubleshooting, and modern software engineering practices.
