Job description

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 new 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 62443 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
