Mission

• Take ownership of the Tariffication application and lead a structured knowledge-transfer process with the retiring Java developer.
• Design, implement, and operate backend services and APIs using Java 17/11/8, Spring 4/5, and Spring Boot 2.x/3.x.
• Build and maintain REST and SOAP APIs; manage HTTP layers and API specifications using OpenAPI/Swagger.
• Develop supporting front-end and administrative consoles in Vue.js or Angular where relevant to platform operations.
• Integrate with Oracle and Microsoft SQL Server using JPA/Hibernate; contribute SQL and PL/SQL and manage schema changes through Liquibase.
• Implement and maintain YAML-based CI/CD pipelines with Maven and Git, including quality gates and automated testing.
• Apply secure authentication and authorization patterns, including Kerberos and OAuth2/OIDC, and follow AppSec best practices such as OWASP guidance, input validation, and secure secrets handling.
• Contribute to test strategy and automation using JUnit 5, Mockito, Cucumber for BDD/ATDD, and Jest for front-end unit tests.
• Support production operations by troubleshooting incidents, analyzing performance, and driving reliability improvements.
• Document APIs, architecture decisions, runbooks, operational procedures, and application knowledge; track work in JIRA.
• Collaborate with application, platform, QA, security, and business stakeholders to align software architecture with business goals and platform standards.

Key Responsibilities During Knowledge Transfer

• Build a clear understanding of the Tariffication application's business rules, pricing and fee logic, integrations, data model, deployment model, and operational dependencies.
• Capture undocumented knowledge, known limitations, recurring incidents, support procedures, and critical troubleshooting steps.
• Review existing source code, architecture documentation, database objects, CI/CD pipelines, monitoring, and release processes.
• Establish and maintain practical runbooks for incident response, deployment, rollback, batch or interface failures, and common production issues.
• Identify technical debt, operational risks, security gaps, and opportunities to improve maintainability and resilience.
• Become a dependable point of contact for the Account & Fees team and related support teams after the transition.

Key Qualifications

• 7–15 years of professional software engineering experience, with a proven track record supporting production systems.
• Strong backend development experience with Java 8 or later; Java 17 or the latest LTS is the target for all applications.
• Hands-on experience with Spring 4/5 and Spring Boot 2.x/3.x.
• Experience designing and maintaining REST and SOAP APIs, HTTP layers, and OpenAPI specifications.
• Exposure to Vue.js or Angular for operational and administrative user interfaces.
• Experience with Oracle and Microsoft SQL Server, including JPA/Hibernate, SQL, database performance fundamentals, Liquibase, and beginner-level PL/SQL.
• Practical CI/CD and DevOps experience with Git, Maven, YAML-based pipelines, and test automation integration.
• Knowledge of Kerberos and OAuth2/OIDC, together with secure coding and AppSec practices covering SQL injection, XSS, RCE, input validation, and secrets management.
• Experience with JUnit 5, Mockito, and Cucumber for BDD/ATDD; Jest experience for front-end unit testing.
• Ability to understand software architecture and document it clearly.
• Fluent English; French is useful.
• Organized, reliable in production support, and able to communicate clearly across teams.

Nice to Have

• Experience with rule engines or BPMN tools, such as Drools; beginner level is acceptable.
• Node.js experience for tooling or auxiliary services.
• End-to-end testing experience with Cypress, Protractor, Selenium WebDriver, or Playwright.
• API or load-testing experience with JMeter; availability of the tool may vary by environment.
