- Contract
We have a current opportunity for a Senior InfoSec Advisor (IRM Manager) on a 12 month PAYE contract basis
The role will be focussed around Design and implementing segregated network environments for capital well projects across yards, vessels, offshore assets and onshore integration points, ensuring secure, resilient connectivity from construction through commissioning and BAU handover.
Work with operators, EPCs and MSPs to define interface boundaries (corporate vs. project vs. OT), regulatory requirements and cutover plans.
Key Responsibilities
Design & Architecture
Produce HLD/LLD, addressing and segmentation (contractor/user/OT zones) with strict separation from core corporate networks.
Define firewall policies, NAT, VPN patterns and remote access for project actors and vessels; document interface contracts to operator/vendor networks.
Engineer QoS and telemetry paths for OT/production data flows (e.g., historian/EC feeds) and collaboration tools used by build/commissioning teams.
Security & Compliance
Apply security baselines (hardening, logging, vulnerability management), integrate with SOC/MSSP, and maintain audit evidence.
Implement identity and access controls for multi-organisation teams; maintain change control and configuration records throughout project phases.
Delivery, Testing & Cutover
Lead lab validation, FAT/SAT, site acceptance and pre-cutover rehearsals; maintain rollback plans and operational runbooks.
Coordinate execution windows with offshore schedules and operator constraints; lead escalations during cutover.
Stakeholder & Vendor Management
Coordinate with operators, EPCs and subsea/FPSO contractors; manage telecoms and satcom vendors.
Provide regular status reporting, risk/issue management and cost tracking to project leadership; ensure full BAU handover documentation.
Role DimensionsHands-on delivery with design authority across multiple concurrent offshore workfronts (yards, vessels, platforms/FPSO).
High stakeholder complexity; strict interface boundaries across operator/EPC/MSP/vendor networks.
Safety-critical, schedule-driven environment across onshore/offshore teams.
Role Requirements
7+ years’ network engineering with offshore/capital project delivery (energy/oil & gas preferred).
Deep knowledge of routing/switching, firewalls, VPN, segmentation, network security monitoring and SD-WAN.
Experience engineering connectivity for platforms/FPSOs and vessels (satcom/VSAT and/or LEO) and integrating with SOC/MSSP.
Strong documentation and change control discipline; confident leading FAT/SAT and complex cutovers.
Certifications advantageous (e.g., CCNP, NSE, AZ-700).
