About the Role
Sekuro is looking for an experienced Firewall and Network Security Engineer for a critical data centre migration programme on behalf of one of our clients. The role will be embedded as a genuine working member of the client's EMEA infrastructure team, reporting to the EMEA Head of Information Security. The scope covers two data centre facilities in Poland and a DR site in Madrid. The objective is straightforward; assess the existing firewall and routing environment, build a clean and optimised policy set from the ground up, and deliver a migration-ready configuration that enforces proper segmentation, least privilege access, and a materially reduced risk profile before migration execution begins.
What You'll Do
- Perform a detailed review of all existing firewall rule sets (L3–L7) and routing configurations (BGP, OSPF, static routes), mapping traffic flows to the target three-tier architecture and validating zone placement and access policies.
- Identify and document redundant, obsolete, overly permissive, conflicting, and non-compliant rules, as well as validate segmentation across DMZ, Internal segments and country-specific sub-nets.
- Develop rulebase optimisation recommendations and deliver a clean, portable, and auditable configuration ready for cutover.
- Produce a comprehensive Firewall and Routing Assessment Report.
- Create a Firewall Rule Rationalisation Matrix (retain / modify / remove).
- Conduct a gap analysis against the three-tier architecture model and internal security policies.
- Propose a future-state rule design aligned with segmentation zones.
- Provide a prioritised risk assessment with remediation recommendations.
- Deliver a migration-ready, optimised firewall rule set.
- Prepare an executive summary for senior stakeholders.
What You'll Need
You will bring extensive hands-on experience across enterprise firewall platforms including Palo Alto Networks, Check Point, Fortinet, and Cisco ASA/Firepower, combined with strong expertise in network segmentation, L3–L7 traffic filtering, and routing protocols. A proven track record in data centre migrations and firewall rule auditing at scale is essential, as is a solid grounding in three-tier architectures and Zero Trust principles. Just as important as the technical ability is the capacity to communicate clearly; this role requires someone who can engage confidently with network engineers and executive stakeholders alike and produce documentation that is structured, precise, and actionable. Experience with cloud networking (Azure/AWS), micro-segmentation, rule analysis tools such as AlgoSec, Tufin, or FireMon, and certifications including CISSP, CCSP, PCNSE, or CCNP Security would all be well regarded.
