Job description

Operations Engineer – Middle Office

Nine Mile

Sydney, Australia

Nine Mile is an electronic principal trading firm focused on market-making and arbitrage opportunities globally. Technology is at the forefront of our business, powering Nine Mile’s unified global trading platform and the micro-decisions required for successful trading.

Nine Mile’s scale and efficiency allow us to be nimble, responding quickly to market opportunities and regulatory changes, whilst operating within a robust operational risk management framework.

At our heart, it’s our people that power Nine Mile – our strategy, technology, and relationships. We are proud to have a team of highly motivated, intelligent individuals who strive to solve complex problems through creative, sophisticated technology in an open, meritocratic environment.

The Role

Join Nine Mile’s Operations team in Sydney as an Operations Engineer in the Middle Office. This is a hands‑on role that combines running the operational backbone of the firm with building the automated systems that backbone depends on. You’ll sit close to the trading desk, own the systems and processes behind settlement and reconciliation, and help scale operations as we expand into new markets and products.

Key responsibilities include:

• Building, operating, and improving the automated systems the operations function depends on, including their monitoring and failure handling
• Scoping and building new tools and workflows to support the firm’s expansion into new markets and products
• Overseeing settlement across different markets, identifying exceptions in advance of failure
• Reconciling internal records against those of our clearing banks and counterparties, investigating any breaks and addressing their root cause
• Providing day‑to‑day support to the trading desk, resolving issues as they arise and eliminating those that recur
• Owning the reporting owed to regulators, exchanges, and counterparties

What You Will Bring

• Strong logic and systems-oriented thinking – the ability to break a problem down into its component parts and design a robust process with clear, defined steps that delivers a lasting solution
• Ownership – the desire to take responsibility for the function independently, and to drive the improvement and growth of the operational systems behind it
• Accuracy under time pressure – much of the work falls within narrow windows around the market open and close
• Clear communication – direct daily interaction with traders, our clearing bank, issuers, and exchanges
• Programming ability is an advantage but not a prerequisite – we work primarily in Python, and a demonstrated history of automating your own work in any toolset is equally relevant
• Proficiency and interest in AI and technology generally – much of our development now involves AI tools, and we expect them to be used capably and with scrutiny. More broadly, we encourage people to seek out different tools and solutions that improve how we operate
• 0–3 years’ experience preferred. Prior exposure to settlement, clearing or securities operations, advanced Excel, SQL, or Linux systems is desirable but not required. Any experience designing or automating a process, in any context, is equally useful

Our Culture

At Nine Mile, we operate in a highly competitive and dynamic environment. Our success depends not only on our vision, technology, and strategies, but on the people who bring them to life every day.

We foster a culture that rewards open interaction, rigorous problem‑solving, creativity, and teamwork. We believe helping others succeed is as important as individual achievement.
