• Translate complex OT security risks into business impact for non‑technical stakeholders
• Collaborate with IT security teams to ensure cohesive security across IT/OT boundaries
• Work effectively with senior client stakeholders (CISOs, Heads of OT, Operations Directors)

What You’ll Need

• 4–6 years of experience in cybersecurity with demonstrable OT/ICS security exposure
• Understanding of Industrial Control Systems (SCADA, DCS, PLC) and their unique security challenges
• Knowledge of OT security frameworks and standards (IEC 62443, NIST CSF, ISA/IEC 62443)
• Familiarity with OT‑specific regulations (NIS, NIS2, CAF, CRA)
• Understanding of the OT threat landscape and attack vectors specific to industrial environments
• Ability to work with both waterfall and agile methodologies across the full delivery lifecycle
• Strong communication skills with ability to engage both technical and operational stakeholders
• Willingness to travel across the UK as projects require

Highly Valued

• Experience in Energy, Utilities, Manufacturing, Aerospace, Defence, or Critical National Infrastructure sectors
• Hands‑on experience with OT network architectures, protocols (Modbus, DNP3, OPC), and segmentation strategies
• Professional certifications: GICSP, IEC 62443, CISSP, GRID or similar
• Understanding of safety systems (SIS) and their security requirements
• Knowledge of common OT security technologies (firewalls, IDS/IPS, asset management tools)
• Experience conducting OT security assessments or penetration testing

What We Offer
