Java Platform Engineer

📍hybrid work 2/3 days per week from the office. ul. Marynarska 12 Project Description: The project is focused on improving the security, release reliability, maintainability, and operational resilience of business-critical banking applications. Forward Deployed Engineers conduct targeted, hands-on engagements with development teams facing challenges related to vulnerability remediation, automated testing, legacy technology, production stability, and release management. The role combines software engineering, DevOps, SRE, test automation, application security, and legacy modernization. Approximately 70% of the work involves hands-on coding and configuration across development, testing, deployment, and production support activities. The technical scope includes building automated test suites, remediating vulnerabilities, modernizing Java and Spring applications, improving CI/CD pipelines, containerizing applications, automating deployments, and implementing observability and resilience practices. The Senior Forward Deployed Engineer is expected to take ownership of end-to-end implementation and delivery activities, working directly with development teams and client stakeholders to deliver production-ready solutions, improve engineering practices, and ensure successful deployment and stabilization of technical changes. Responsibilities: Own end-to-end delivery of assigned technical initiatives, from requirements clarification through implementation, testing, deployment, and post-production stabilization. Work directly with development teams and client stakeholders to deliver reliable production-ready solutions. Assess application code, dependencies, runtime environments, test coverage, deployment architecture, CI/CD pipelines, observability and operational risks. Write, debug, review and improve production-quality code and configuration. Develop and enhance unit, integration, component, contract and deployment tests using Test-Driven Development practices. Create and maintain automated testing solutions integrated into CI/CD pipelines. Conduct vulnerability remediation, dependency analysis, regression testing and secure coding improvements. Upgrade Java, JVM, Spring, NPM and application dependencies to supported versions. Modernize Java applications and legacy middleware platforms. Containerize applications using Docker and support deployment to OpenShift environments. Design, implement and improve CI/CD pipelines to support reliable and repeatable releases. Improve Git workflows, code-review practices, development standards and delivery quality. Implement observability and operational resilience practices including logging, metrics, tracing and monitoring. Support production deployments, troubleshooting, diagnostics and stabilization activities. Contribute to engineering standards, documentation and knowledge sharing across teams. Mandatory Skills Description: The role requires a strong hands-on engineering background with recent experience developing, modernizing and supporting production applications. Candidates are expected to actively write, review, debug and deploy code while working across software engineering, platform engineering, security, testing and operational domains.
