- Design and implement solutions involving Kafka and event-driven integrations where applicable
- Investigate complex legacy code and deliver solutions that address vulnerabilities without compromising business functionality
- Drive the upgrade of vulnerable libraries, frameworks, and application dependencies, including planning and risk mitigation
- Perform code-level remediation based on security findings, threat modeling, and secure development practices
- Diagnose and resolve complex issues resulting from security fixes, dependency upgrades, or legacy implementations

- Lead code reviews, testing strategies, and validation of implemented fixes
- Collaborate closely with developers, QA engineers, architects, product stakeholders, and other team members, providing technical guidance
- Mentor less experienced engineers and share knowledge across the team
- Drive continuous improvement of application security, technical quality, and engineering practices

Requirements

- 3+ years of commercial software development experience with Java
