Job Description
Everyone tells junior engineers the same thing about OT security: “come back when you have experience.”
Nobody explains where that experience is supposed to come from.
I'm fixing that for exactly one person.
InfraSec is hiring a Resident OT Cybersecurity Engineer for an 18-month deployment on a major offshore energy new-build at a Singapore yard — working directly under me as your technical authority and mentor (I'm one of the few ISA/IEC 62443 Expert-certified professionals in Singapore).
What you'll actually do:
Verification, evidence review, cybersecurity test witnessing and punch tracking on live PLC/SCADA systems and redundant OT networks — client-facing, every single day, on one of the most complex industrial projects in the region.

What I'm looking for:
▪ 1–4 years in networking and/or security operations (Security+/CCNA level)
▪ Degree or diploma in engineering or infocomm
▪ OT/ICS, marine, energy or field exposure is a plus — not a must
▪ Strong documentation discipline (this trade runs on evidence)
▪ Ready to be on-site at a Singapore shipyard every working day — boots, not just keyboards
▪ Singapore citizens/PRs preferred; strong regional candidates welcome — we sponsor the EP
What you get:
Explore our comprehensive directory of visa sponsorship jobs from employers worldwide who are ready to sponsor talented international professionals.
▪ S$4,800–6,200 base (experience-dependent) + site allowance + completion bonus
▪ Sponsored ISA/IEC 62443 Fundamentals certification
▪ Structured onboarding and 18 months of daily mentorship in a discipline almost nobody teaches
▪ A CV line most engineers wait a decade for
The honest part: this is yard work. Safety boots, hot afternoons, test campaigns, discipline. If that sounds like a downgrade — this isn't for you. If it sounds like the fastest possible entry into critical-infrastructure security in Singapore — it is.
DM me, or email careers@infrasec.sg with “RESIDENT OT” in the subject line. Include your notice period. We're shortlisting within 2 weeks.
