WE'RE HIRING Building Cadet
Sunshine Coast, QLD | Full-Time or Part-Time (flexible around study)
This Isn't a Fetch-the-Coffee Cadetship
We'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 Get
Real Exposure, Not Admin
You'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 Site
You'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 Succeed




You'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 Study
Your degree matters.
We'll structure your hours around your commitments, not the other way around.
Plenty of our people have done exactly this.
A Explicit Career Path
This 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 Enjoy
Relationships– 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.
You'll know everyone's name in your first week.
What You'll Be Doing
Supporting Project Managers and Contracts Administrators across live projects




Preparing project start-up documentation — safety documents, ITPs, site set-up packs
Assisting with procurement — scoping packages, raising purchase orders and subcontracts
Reviewing drawings, specifications and consultant documentation
Helping track programmes, progress claims and project reporting
Managing RFIs, submittals and document control
Attending site visits, site meetings and client meetings
Coordinating with subcontractors, suppliers and consultants on day-to-day delivery
Learning how projects are handed over — defects, O&M; manuals, close-out
Who We're Looking For
Currently studying or recently completed Construction Management, Civil Engineering or a related degree
Genuinely interested in building a long-term career in commercial construction
Strong attention to detail — in this industry, the details are the job
Asks questions, puts their hand up, and gets involved
Comfortable talking to people — subbies, suppliers and site teams, not just a screen
Organised, and follows through on what they said they'd do
Drivers licence
Industry or site exposure is a bonus, not a requirement
Attitude matters more than experience.
We can teach the rest.
This Cadetship Probably Isn't For You If:
You'd rather be told exactly what to do every step of the way
You're uncomfortable speaking up or asking when you don't know something
You want a desk job with no site time
You're looking for a title rather than a trade to learn
What Happens Next
Tell us:
Why construction?
What made you choose it?
Something you've taught yourself — in or out of study — and how you went about it.
Why Plexxcon?
Why now?
Your study commitments and the availability that works for you.
If you're after a cadetship where you'll be challenged, supported and actually developed, we'd like to hear from you.
