WE'RE HIRING Building CadetSunshine Coast, QLD | Full time or Part-Time (flexible around study)This Isn't a Fetch-the-Coffee CadetshipWe're looking for a cadet who actually wants to learn how construction gets delivered.Not someone waiting to be given a filing job.
Someone curious, willing to ask questions, and ready to get involved from day one.At Plexxcon, you'll work alongside our Project Managers, Contracts Administrators and Site Teams on live projects — learning how a job is planned, procured, programmed and built.
You'll be in the thick of delivery, not watching it from a distance.
From there you'll grow with clear pathways into Contracts Administration, Project Management or Site Management.We deliver complex construction projects from $250K to $15M across Southeast Queensland, working inside live operational environments — hospitals, universities, schools, retail centres, sports clubs, industrial facilities and high-end commercial spaces.Our clients don't stop operating while we build.
That means communication matters.
Planning matters.
Relationships matter.
Every decision has an impact.It's a demanding place to learn.
It's also the fastest way to learn properly.What You'll GetReal Exposure, Not AdminYou'll work on live projects from start-up through to handover.
Programmes, procurement, subcontractor coordination, RFIs, variations, site inspections, progress reporting and client meetings.
You'll see how the decisions made in week one show up in week thirty — and why a well-run project feels calm while a poorly-planned one never does.Time on SiteYou'll get out of the office regularly.
Walking sites with our Site Managers, watching trades sequence, understanding what's actually achievable versus what looks fine on a programme.




You can't learn this part from a textbook.Mentorship From People Who Want You to SucceedYou'll be taught by experienced Project Managers, Contracts Administrators and Site Managers who've delivered hundreds of projects between them.
Our leadership team is accessible and hands-on.
Ask questions — you'll get answers.Flexibility Around Your StudyYour degree matters.
We'll structure your hours around your commitments, not the other way around.
Plenty of our people have done exactly this.A Clear Career PathThis isn't a dead-end role.
We'll build your development around your strengths, with in-house upskilling and annual performance and development reviews where we talk openly about where you're heading, what you want to learn, and what's next.
As Plexxcon grows, we want our people to grow with us.A Team and Culture You'll Actually EnjoyRelationships – We value strong relationships with our clients, subcontractors, suppliers and each other.
Construction is a people business and we never lose sight of that.Hustle – We move quickly, take ownership, and don't wait to be told what needs to be done.Solutions – Complex projects require smart thinking, collaboration and problem solving, not finger-pointing.Provide Value – We deliver quality outcomes that make commercial sense.Bi-monthly team BBQs, social events throughout the year and a leadership team genuinely involved in the day-to-day.
