OT Cybersecurity Hiring in UK Manufacturing: The 2026 Picture
NIS2 and rising attack surface have made OT cybersecurity a board-level concern. The talent pool is small - here is how UK manufacturers are building it.
The EU NIS2 Directive, transposed into national law across member states through 2024–2025, has materially raised the compliance bar for operators of essential services and important entities - many of which are mid-sized manufacturers. The UK's own NIS Regulations 2018 are being updated through the Cyber Security and Resilience Bill announced in 2024, with similar effect on UK operators.
The convergence of IT and operational technology has created a hiring problem that neither side of the IT/OT boundary alone can solve. Candidates with deep PLC, SCADA and DCS experience are typically light on enterprise cyber tooling, while traditional cyber engineers rarely have shop-floor exposure.
Demand is concentrated around IEC 62443-literate engineers - particularly those with hands-on experience of zoning, conduit design and segmentation in live plants. UK National Cyber Security Centre guidance has reinforced the same approach, accelerating adoption among critical national infrastructure operators.
Salary bands have moved sharply: dedicated OT cybersecurity engineers with 3–7 years' experience cluster at £75,000–£95,000, while OT security architects with regulated-sector exposure (energy, water, pharma) regularly clear £110,000.
The pragmatic hiring strategy for mid-sized manufacturers is hybrid: hire one experienced OT-cyber lead and surround them with internal automation engineers cross-trained through SANS ICS courses, GIAC GICSP or Siemens / Rockwell-led OT security programmes.
