Lead. Influence. Build excellence in OT cyber security.
SIS is a specialist OT / industrial cyber security consultancy. OT is all we do, for critical infrastructure and industrial organisations across Asia Pacific and the Middle East. We're strengthening our Perth presence and need a senior practitioner to lead delivery here.
Who this role is for
This is an OT role first. You've spent a significant part of your career delivering security in control system environments: on site, working alongside engineers and operators, and accountable for the outcome. If your OT experience has mainly been oversight within a broader IT or enterprise cyber role, this won't be the right fit.
What you'll do
Own delivery of complex OT / IC security engagements to time, cost and quality
Lead work across FEED, GRC, threat and risk assessments (including penetration testing), security architecture and design, implementation, OT‐SOC and training
Advise senior client stakeholders across engineering, operations, cyber and executive leadership
Provide technical leadership and peer review to SIS quality and assurance standards
Mentor consultants and contribute to competency assessment and team capability
Improve how we work, including practical use of current tools and AI
What you'll bring




Hands‐on experience securing control systems (SCADA, DCS, PLC or similar) in operating industrial environments; utility experience highly regarded
Practical experience testing field devices and industrial control components (penetration testing or vulnerability assessment), and the ability to lead that work
An engineering qualification or equivalent technical background
A track record leading complex OT security consulting engagements with autonomy, including owning the client relationship and commercial outcomes
Credibility with engineering, operations, cyber and executive audiences
IEC ***** and/or GICSP highly regarded; OSCP, CISSP or equivalent also considered
Practical use of AI and technology to deliver quality work more efficiently
Asset owner or operator experience is a plus
Why SIS
100% OT focus, with a track record of trusted delivery in critical infrastructure
Work that stands up to engineering, operational and executive scrutiny
Real influence: senior consultants shape our standards, methods and growth
Regional delivery across Asia Pacific and the Middle East without losing specialist depth
