Operation and Accounts Officer
Location: North Sydney
Contract: Full-time, October 2025 – June 2026 (maternity leave cover position)
Reports to: Financial controller
Join GreenDeal – a fast-growing clean-energy platform helping retailers and installers make the most of STCs (Small-scale Technology Certificates) and speed up Australia’s shift to renewables. We’re part of the OSW Group and we’re scaling fast – which means we need sharp, detail-driven people who thrive in a fast-paced, problem-solving environment.
This role is perfect for someone who loves numbers, systems, and keeping things running smoothly behind the scenes – but also wants to work in a business with purpose, energy, and a great team vibe.
💡 What you’ll be doing
STC Trading: Stay on top of the market, trade registered STCs, and keep inventory + pricing in check.
Money Moves: Manage daily cashflows, payables, and reconciliations like a pro.
Credit Control: Keep customer credit limits in line and make sure accounts stay healthy.
Xero Wizardry: Process invoices, reconcile accounts, and handle bank recs daily.
Reporting & Admin: Pull reports, prep updates, keep inboxes in check, and make sure the team has the info they need.
Compliance & Recovery: Sort rejected jobs, manage prepaid invoices, and support reward programs.
🧩 What we’re looking for
Proficient in Mandarin
2–4+ years in accounts, operations, settlements, or trading support (bonus if you’ve touched energy/renewables).
Confident with Xero (bank recs, pay runs, invoicing).
Excel / Google Sheets skills (vlookups, pivots, reconciliations).
Big on accuracy and detail – small mistakes = big headaches here.
Clear, professional communicator who can juggle multiple priorities.
A self-starter who owns their work and isn’t afraid to suggest improvements.=
🎉 Why join us?
North Sydney office with plenty of coffee, city views, and an easy commute.
Work with purpose – everything you do helps drive Australia towards a clean-energy future.
Great team culture – supportive, ambitious, and fun.
Future opportunities – OSW Group is growing fast, so there’s always room to grow with us.
📅 Start date: October 2025
📅 Contract: Maternity leave cover until June 2026 (8 months)
