Job description

Your role

OT Functional Architect operates at enterprise and practice level to translate operational reality within water and utilities environments into robust functional and non‑functional requirements for enterprise SCADA and IT/OT convergence solutions. The role ensures that proposed architectures are safe, operable, maintainable, and resilient, while enabling scalable transformation across multi‑site estates with minimal operational disruption.

Key responsibilities

• Lead enterprise and site-level discovery of OT capabilities, including PLC, SCADA, HMI, control strategies, alarm philosophies, interlocks, and safety constraints.
• Capture and model operational processes across the asset lifecycle, including commissioning, maintenance, incident response, overrides, escalation, and ICC-to-site handover.
• Define functional and non‑functional requirements for remote monitoring and control, including authorisation models, auditability, fallback modes, and resilience expectations.
• Identify, assess, and quantify migration constraints across brownfield environments, including cutover strategies, downtime tolerances, rollback requirements, and legacy/vendor limitations.
• Develop site categorisation models (criticality, complexity, connectivity) and readiness assessments to inform phased enterprise rollouts.

Your profile

You’ll have a strong hands‑on background in OT/ICS engineering within water or utilities, with direct experience of PLC and SCADA integration, commissioning, and operating safely in regulated environments. You’re comfortable working across complex brownfield estates and multi‑vendor OT landscapes, and can translate operational realities into clear functional requirements and architectural inputs. You work confidently with a wide range of stakeholders and stay aware of emerging IT/OT technologies and patterns.

Key strengths

• OT/ICS engineering expertise, including safe change, alarm management, and operational governance.
• Ability to bridge operations, engineering, and leadership, with awareness of modern IT/OT and digital trends.

Requirements

• All roles will require a level of security clearance; BPSS, Security Clearance, or Developed Vetting.
