Accounts Payable/Receivable Specialist

Company Overview

Metrea delivers effects-as-a-service to national security partners across five domains and more than a dozen mission areas. These include airborne ISR, electronic warfare, secure communications, aerial refuelling, special air missions, aerial firefighting, and advanced simulation. We own the whole stack: designing, building, and operating turnkey capabilities that give our partners decisive, asymmetric advantage against rapidly evolving threats.

Our operating model is built around three interlocking pillars. The Support Groups provide a global shared-service – spanning people, finance, platform, operations, legal, and engagement. This frees up our Core Groups, who develop and own mission capabilities end-to-end, to focus entirely on delivery. The Market Groups apply a regional lens, ensuring that our agile and adaptable capabilities remain aligned to the wicked problems that matter most to our partners across the Americas, EMEA, and Asia-Pacific.

At the heart of our model is a simple but powerful idea: be a true partner with skin in the game. Our partners need effects, not just equipment. By owning the full stack – from the lab to the field – we are able to drive a continuous cycle of innovation that keeps our partners ahead. It's a fast-moving, intellectually demanding environment where talented people are given real responsibility, work on problems that matter, and contribute to an enterprise that is growing quickly and deliberately.

Headquartered in Washington, DC, with facilities across the United States, the United Kingdom, as well as Continental Europe and Asia-Pacific.

Group Overview

Metrea is actively building its presence in Australia as part of a deliberate, globally coordinated expansion into the Asia-Pacific region. Our Asia-Pacific Market Group, headquartered in Brisbane with an additional office in Perth, is the enterprise's dedicated regional interface — connecting Australia's national security community with Metrea's full suite of capabilities across three core domains: Aerospace, Electromagnetic & Cyber, and Digital & Synthetic. Metrea is now bringing that same depth of mission expertise and proven operating model to Australia.

Underpinning these capabilities is a global network of Support Groups spanning people, finance, platform, operations, legal, and engagement, ensuring that as we grow in Australia, we do so with the full weight of an established global enterprise behind us.

Metrea's solutions are built for elegance: effective, efficient, and evolving; enabling our partners to scale capacity and achieve asymmetric advantage against rapidly evolving threats.

Position Summary

In this role, you will be the driving force behind the end-to-end accounts payable function, ensuring that every supplier transaction is processed with precision and integrity. You will take full ownership of the PR/PO/invoice matching process, accurately coding invoices for GST compliance and managing timely EFT payment runs to maintain strong vendor relationships. Beyond the numbers, you will act as a critical gatekeeper of company funds, performing rigorous statement reconciliations and managing the master vendor file to mitigate risk and ensure full alignment with ATO requirements. Your expertise will be vital during month-end closing, where you will provide the clarity and accuracy needed to keep the business moving forward. 

In addition to managing the payables function, you will oversee the Accounts Receivable lifecycle by accurately generating and issuing sales invoices. You will serve as a primary point of contact for clients, proactively following up on outstanding balances and performing regular debtor reconciliations to ensure a healthy cash flow. By maintaining a clean and up-to-date aged receivables ledger, you will provide the business with essential visibility into its incoming revenue and overall financial position.

To be successful in this role, you will possess a sharp eye for detail and a robust understanding of the Australian accounting landscape, particularly regarding GST compliance.  You will be a dedicated collaborator, thriving in a team-based environment where sharing knowledge and supporting your peers is essential to meeting collective deadlines. Your ability to build rapport across different departments and communicate effectively with both vendors and clients will ensure a seamless flow of financial information. Ultimately, your success will hinge on your commitment to teamwork, your proactive approach to assisting others, and your drive to ensure the business's cash flow remains accurate, transparent, and fully optimised.
