Senior Java Platform Engineer – Banking Sector

The position is a senior‑level Java Platform Engineer working for a banking‑focused organization that builds and runs core backend services. The team delivers APIs and supporting tools that enable the institution’s digital operations, using a modern Java stack and related technologies. Day‑to‑day work involves creating and maintaining server‑side components with Java 17, 11 or 8, together with Spring 4/5 and Spring Boot 2.x/3.x. You will design both RESTful and SOAP interfaces, define their contracts through OpenAPI/Swagger, and occasionally develop front‑end admin panels in Vue.js or Angular. Integration tasks include connecting to Oracle and Microsoft SQL Server via JPA/Hibernate, handling schema evolution with Liquibase, and setting up CI/CD pipelines written in YAML that employ Maven and Git while enforcing quality gates and automated tests. Security responsibilities cover implementing Kerberos and OAuth2/OIDC mechanisms and adhering to OWASP guidelines for input validation and secret management. You will also help shape the testing approach, writing unit, integration and behavior‑driven tests with JUnit 5, Mockito, Cucumber and Jest, and you will be on call for production support, incident analysis and reliability enhancements. The role requires proven expertise in Java (versions 8, 11, 17), Spring frameworks, Spring Boot, REST and SOAP API development, OpenAPI/Swagger, and front‑end frameworks such as Vue.js or Angular. Experience with Oracle and MS SQL Server, JPA/Hibernate, Liquibase, Maven, Git, YAML‑based CI/CD, and security protocols like Kerberos and OAuth2/OIDC is essential. Competence in automated testing using JUnit 5, Mockito, Cucumber and Jest is also mandatory. Additional strengths include familiarity with broader application security practices, performance tuning, and the ability to document APIs clearly.
