Career Series: Strategic Transition from Engineering to Architecture
CyberSG TIG Collaboration Centre (formerly ICE71), 71 Ayer Rajah Crescent, Singapore, SG⚠️ REGISTRATION IS REQUIRED VIA THIS SIGN UP FORM ⚠️
*Please keep a look out for our email on the outcome of your registration that will be sent to you at 1-2 day(s) before the session. If you did not receive any updates, please drop us an email at community@div0.sg*Career Trajectory AMA Series: Real Cybersecurity Career Moves, No Filters
Cybersecurity careers aren’t linear—and many of us reach a point where we start questioning our next move. End user to vendor, private to public sector, engineer to architect, practitioner to GRC—these transitions raise real concerns around skills, pay, identity, and long-term impact. This Career AMA series is built for people navigating those questions.
Every two months, we’ll host an open AMA with cybersecurity professionals who’ve actually made these shifts. No polished success stories or recruitment pitches—just honest conversations about what changed, what was harder than expected, what they got wrong, and what they’d do differently.
Expect candid insights, practical lessons, and space to ask the questions people usually avoid. If you’re considering a career move—or just want clarity on what’s possible in cyber—this series is for you.

TRAINER
KK "Jim" Tan — Founder, counterShell
As a mid-careerist convert to cybersecurity, Jim picked up his practical skills through getting OSCP certified and by participating in a variety of CTFs. In his career at CSIT, he performed a variety of red-teaming and vulnerability research roles and established the Cyber Training School at CSIT as the Lead Instructor. Besides the OSCP certification, Jim is also OSCE and OSEE certified, and has a Bachelor's degree in Social Science (Psychology). He now sees psychology as a field of study where you fuzz humans until they produce unexpected behaviour.SPONSORS
