Holding ISO 9001, 14001, and 45001 certifications, we operate to the highest standards in some of the Territory's most demanding environments.

We're in an active growth phase — and we need the right person behind the scenes to help us scale.

THE ROLE

This is a hands-on, office-based role supporting our operations and business development functions. You'll be the organisational backbone of a fast-moving team — keeping things on track, well-documented, and running smoothly day to day.

It's a genuine opportunity to grow with a business that's going places, not just fill a seat.

WHAT YOU'LL BE DOING

Managing inboxes, correspondence, and scheduling across the team

Supporting document control — project files, contracts, compliance records, purchase orders

Assisting with accounts administration in Xero (invoicing, purchase orders, reconciliations)

Coordinating between field teams, project managers, and external stakeholders

Maintaining our job management system (AroFlo) with accurate project and client data

General office management — supplies, systems, and keeping things organised

Supporting the BDM with proposals, capability documents, and BD admin as needed

WHAT WE'RE LOOKING FOR

Proven experience in an administration role — construction or project-based environments highly regarded

Proficient in Google Docs, Microsoft Office 365 (Word, Excel, Outlook, Teams)

Experience with Xero or similar accounting software is a strong advantage

High attention to detail with a systematic approach to document management

Strong communicator — professional, clear, and reliable

Self-starter who can prioritise competing tasks without constant direction

Comfortable working in a fast-paced, trade-based environment

WHY BGI?

Darwin-based, full-time role with a stable and growing company

Work directly alongside leadership in a business that values your contribution

Real scope to grow as we scale from 10 to 20+ staff over the next 12–18 months

ISO-certified, professional environment with Tier 1 and Defence clientele

Salary commensurate with experience
