ENGINEERING RELIABILITY. BUILT-IN SECURITY/

We design, optimise, and modernise operational technology (OT) and digital infrastructure, with security and compliance engineered in from day one, not bolted on after.

About the role

As Principal OT Operating Model Consultant, you will be the operating model and change authority on SOCI-driven engagements. Based in West Perth, WA, with travel to client sites across Australia, you will design how clients govern, resource, source and run their OT environments, and lead the organisational change required to implement those models. The role is approximately 80% consulting and change and 20% OT domain application, requiring enough OT understanding to work credibly with plant and engineering teams without designing systems. You will partner closely with the Principal OT Systems Architect, who defines what the system must be, while you define how the organisation operates it.

Key responsibilities

- Assess current OT operating models, including structures, roles, processes, tools, sourcing and governance.

- Design future-state OT operating and support models, including organisational structures, decision rights and governance forums.

- Develop RACI and RACII matrices, escalation paths, headcount requirements and service ownership models.

- Build OT service catalogues and define service ownership across OT, IT, cyber, generation and service providers.

- Design OT change, incident and problem management processes and governance, aligning with plant safety and availability constraints.

- Align OT processes with ITIL 4 where appropriate and adapt them to plant operations.

- Map process and governance controls to SOCI CIRMP obligations with partner GRC specialists.

- Define in-house, MSP, OEM and O&M; provider responsibilities and service boundaries.

- Define OT-specific KPIs, metrics and SLAs, and establish performance management frameworks.





- Advise on contract variations and the transition of existing MSP arrangements.

- Define OT role profiles, skills matrices and competency frameworks.

- Run capability gap assessments and design training and capability uplift plans.

- Lead change management activities, including impact assessment, stakeholder analysis, readiness planning and adoption.

- Build implementation and transition roadmaps incorporating resourcing and budget considerations.

- Lead stakeholder interviews, operating model workshops and executive briefings.

- Facilitate steering committee decisions on structure, sourcing and investment.

- Author current-state assessments, RACI models, future-state support models, MSP KPI and SLA frameworks, roadmaps and executive summaries.

- Contribute to proposals, scoping and estimates, and help grow Tier16’s operating model offering.

What we're looking for

- 12+ years of experience in management consulting, operating model design or operations leadership, including 5+ years at principal, director or senior manager level.

- Experience delivering at least two operating or support model redesigns in asset-intensive industries such as power, gas, water, resources or utilities.

- Demonstrated experience in RACI design, service catalogues, governance and organisational design, supported by relevant artefacts.

- Experience designing MSP or outsourcing models, including service boundaries, KPIs, SLAs and transition.

- Experience in organisational change management, stakeholder analysis, change impact, readiness and adoption.





- Experience in workforce and capability design, including role profiles, skills matrices and competency frameworks.

- Working understanding of OT environments, including SCADA, PLCs, control rooms and plant operations, and how they differ from IT environments.

- Working knowledge of the SOCI Act and CIRMP obligations as they apply to governance and people.

- Executive-level facilitation and writing skills, with the ability to guide client executive teams towards decisions.

- Eligibility to work in Australia and the ability to obtain site access and background checks.

- A degree in business, engineering, organisational psychology or a related field; an MBA is advantageous.

- Change management certification such as Prosci or APMG Change Management is desirable.

- ITIL 4 certification, particularly Managing Qualified or Strategic Leader, is desirable.

- Asset management credentials such as ISO 55001 training or an IAM Certificate are desirable.

- Big Four or tier-one consulting experience combined with industry operations experience is desirable.

- Australian energy sector experience, including AEMO, NEM or WEM exposure, is desirable.
