FSI Engineering designs, builds, installs and commissions materials handling, chemical dosing and water treatment systems for clients across Australia and New Zealand.
We work as both head contractor and subcontractor on major infrastructure and industrial projects and we do it end to end, from concept through fabrication, installation and commissioning on site.
AsDesign Manageryou will own the design function within our Projects division.
You'll lead and grow a team of draftspeople and designers, set the technical standards they work to, and remainhands-onacross the more complex packages yourself.
This is a genuine leadership position.
You will have real authority over how design is planned, executed and signed off, and the accountability that goes with it.
What you'll be responsible for
Resourcing and programme – planning design capacity across concurrent projects, setting and holding design programmes, and flagging risk early
Team leadership – leading, mentoring and developing the design team; setting expectations, reviewing performance and building capability
Design review and approval – nothing goes to the workshop, the client or site without your sign-off
Technical governance – drawing standards, model and part libraries, templates, revision control and Vault administration
Safety in Design – facilitating SiD reviews and discharging our designer duties under the WHS Act
Buildability – working with procurement and the workshop so what we draw is what we can efficiently build, and BOMs are right the first time
Client interface – design submissions, technical queries, RFIs, and IFA / IFC / as-built deliverables to head contractors
Engineering coordination – structural, mechanical and process calculations, and managing the RPEQ certification pathway where projects require it
Continuous improvement – finding and fixing the things that slow design down
