- Troubleshoot platform issues, performing root cause analysis and driving long-term fixes
- Support and refine security monitoring capabilities through improved configurations and use-case tuning
- Collaborate with vendors to resolve issues, evaluate capabilities, and guide product adoption
- Contribute to governance, standards, and documentation across supported platforms
- Partner with security operations teams, acting as an escalation point where required
- Drive automation across security workflows using scripting and tooling
What You’ll Bring…
- 5-8 years’ experience in security engineering, infrastructure security, or platform security roles
- Strong hands-on experience with security tooling across EDR, SIEM (e.g. Splunk), SOAR, and network security platforms
- Practical experience with SASE architectures, next-generation firewalls, and proxy technologies
- Solid understanding of networking fundamentals (DNS, IP, routing concepts)
- Experience deploying, upgrading, and integrating enterprise security platforms
- Strong troubleshooting capability, with a structured approach to root cause analysis
- Working knowledge of Linux (RHEL) and Windows environments
- Experience scripting or automating workflows using Python, PowerShell, or similar

- Understanding of the incident response lifecycle, with ability to support escalation scenarios
- Strong communication skills, able to engage both technical teams and stakeholders
- (Preferred) Background in financial services or other regulated environments
