The Opportunity An exceptional opportunity has arisen within a major financial and mobility services enterprise for a technical champion to take ownership of enterprise-scale infrastructure operations. This position bridges the gap between traditional network engineering and modern cyber defense. You will join a tight-knit, collaborative operational tech group where you will be expected to dive deep into complex environments, driving delivery across both day-to-day operations and massive, multi-year business transformations. If you are looking to actively transition your deep networking expertise into a dedicated cybersecurity pathway within a highly structured environment, this is your next step. Core Responsibilities & Technical Deliverables • End-to-End Execution: Drive both business-as-usual (BAU) operational resilience and major project deliverables independently, providing subject matter expertise across the entire environment. • Major Digital Transformation: Play an active role in a massive 2-to-3-year modernization project to replace core transactional and contract systems, building out the foundational infrastructure and defense frameworks to match. • International Technical Collaboration: Partner closely with overseas shared service centers and regional security centers of excellence to roll out and integrate cutting-edge security technologies on a regular basis. • Stakeholder Interfacing: Confidently articulate, explain, and justify complex engineering solutions to technical peers and non-technical business leaders alike. Candidate Requirements To be considered for this position, you must meet the following baseline criteria: • Network Foundations: A minimum of 5 years of professional, hands-on experience designing, maintaining, and protecting large-scale enterprise environments. • Ecosystem Expertise: Practical, deep technical familiarity with the Palo Alto product line and next-generation firewalls is absolutely mandatory. • Clearance & Eligibility: Due to upcoming public sector and government contract support commitments, candidates must hold a UK passport or dual nationality and have achieved a minimum of 5 years of continuous, uninterrupted UK residency to successfully obtain Security Clearance (SC). Any recent travel to politically sensitive regions must be fully declared. • Documentation Skills: A meticulous eye for detail, with a proven track record of producing accurate, robust technical documentation. What We Are Looking For (The "Inside Track") We are looking for an operational doer, not a high-level consultant. The successful candidate will be someone who loves to look under the hood of a technology stack and become the definitive expert on it. A Note on Backgrounds: This role perfectly suits an engineer moving from traditional heavy routing/switching environments into dedicated security operations. Candidates coming from a pure consultancy background without recent hands-on engineering accountability will not be suitable. Why Join This Business? While you will operate within a closely-knit regional team, you will enjoy the stability, structured career progression, and substantial training budgets of a globally recognized brand. How to Apply Please submit your up-to-date CV for consideration. Important Note for Applicants: To ensure a smooth evaluation by the hiring manager, please ensure your CV contains specific, granular engineering examples rather than high-level summaries.Examples of Projects - led from the front on network or security kit and what value your role brought to that process.
