Senior Middleware Engineer – Vulnerability Management

What success looks like in this role:

Key Responsibilities

• Provide day-to-day support for middleware platforms [Oracle WebLogic, Apache Tomcat, JBoss/WildFly, IBM MQ, Apache/IIS], including installation, configuration, upgrades and troubleshooting.
• Lead vulnerability fixes for middleware components: review scan findings, prioritize by risk, and apply patches, version upgrades, configuration changes and hardening.
• Keep middleware compliant with security policies and hardening standards [CIS Benchmarks], and track each fix through to closure.
• Work with Security teams to review new vulnerabilities and vendor advisories, determine which systems are exposed, and plan fixes within agreed timeframes.
• Resolve complex incidents and problems, perform root-cause analysis and put permanent fixes in place to improve availability and reliability.
• Handle incidents, problems and changes through ITSM processes and meet service level agreements.
• Mentor and coach team members, sharing knowledge and documented procedures so the team relies less on escalations.
• Plan and implement new releases, updates and corrections to middleware and related applications.
• Develop and maintain scripts and automation [Bash, Python, WLST, Ansible] to streamline patching, vulnerability fixes, deployments and routine operational tasks.
• Evaluate, recommend and maintain monitoring and management tools.
• Contribute to middleware projects, capacity planning and service improvements as capacity permits.
• Explain technical issues and risks clearly to non-technical stakeholders.
• Maintain documentation, runbooks and knowledge articles.
