A leading global proprietary trading firm is growing its production operations engineering team in Sydney. The firm trades its own capital and provides liquidity across listed derivatives, equities, ETFs, bonds and FX, with the Sydney office acting as a key hub for its Asia-Pacific trading.

You'll join a global team whose job is simple to describe and hard to do well: keep low-latency trading systems safe, stable and fast. It's a hands-on role with genuine ownership of production, close to the trading floor and the engineers who build the platform.

The role

• Deploy, maintain and monitor proprietary trading applications, keeping them within tight performance thresholds
• Support live trading, troubleshooting complex issues and resolving incidents quickly
• Spot recurring themes in incidents and build the automation that stops them coming back
• Coordinate go-lives for new products, systems and exchanges, including readiness for corporate actions and special announcements
• Set configuration and deployment standards, and manage colocation capacity and redundancy as the firm grows

What you'll bring

• L2/L3 experience managing complex distributed systems on Linux, with strong networking fundamentals
• Python (or similar) scripting, plus hands-on CI/CD, build, deployment and version control tooling
• Experience with relational databases such as PostgreSQL
• A track record of driving system improvements and delivering change across global teams
• Calm, logical troubleshooting under pressure, and the ability to explain technical issues clearly

Note - High-frequency trading experience is a plus, but genuinely not required.

Culture:

• Highly collaborative, working daily with traders, developers and operations teams across regions
• Fast-paced and high-intensity, with frequent change and plenty to learn
• A team of curious, creative problem solvers who care about continuous improvement
• Primarily business hours, with a rotational weekend roster supporting weekend trading and testing
