Senior Software Engineer, Actimize

Senior Software Engineer — Fraud Detection Platform

About the Role

We are looking for a Lead Software Engineer to maintain and evolve the web applications that power our fraud detection platform. The role spans both modern and legacy Java web stacks, including authentication and access control.

You will be the technical steward for these applications: keeping them stable, secure, and supportable; modernizing where it makes sense; mentoring other engineers; and partnering with product, QA, and operations to deliver reliable changes.

What You’ll Do

* Own and evolve applications across the UI, server-side, persistence, and integration layers.
* Diagnose and resolve production issues end-to-end across current and legacy stacks.
* Design and implement enhancements requested by product and customer-facing teams.
* Keep dependencies and application frameworks patched, secure, and supportable.
* Improve test coverage and overall engineering quality.
* Lead design and code reviews, and provide technical guidance to other engineers.
* Mentor junior and mid-level engineers.
* Participate in releases, production support, and on-call rotations.

Required Experience

* Strong Java experience from production work on non-trivial systems.
* Production experience with JSF and a JSF component library such as RichFaces or PrimeFaces, including Facelets/xhtml.
* Solid CDI experience and servlet container deployment experience with Apache Tomcat or similar.
* Experience with JBoss/WildFly application servers and EJB-based enterprise Java applications.
* Strong Hibernate/JPA skills and proficiency with SQL.
* Web fundamentals: HTML, CSS, JavaScript, and the JSF AJAX lifecycle.
* Git-based development workflows and a track record of debugging complex production systems.

Strongly Preferred

* Experience maintaining and modernizing long-lived enterprise Java codebases, including dependency upgrades, framework migrations, and gradual de-risking of legacy stacks.
* Hands-on experience with authentication and authorization systems such as SSO, SAML, session management, and token handling.
* Security mindset, including XSS/CSRF prevention, output encoding, secure session handling, and OWASP Top 10 remediation.
* Web testing experience with JUnit, Selenium/WebDriver, and Arquillian.
* Experience in fraud, payments, banking, or other financial services domains.
