Python Developer

Python Software Engineer – Trading Systems

Sydney (Sponsorship on offer to relocate the right candidate)

We’re working with a top-tier proprietary trading firm that’s quietly building out its core technology group.

This role sits close to trading, you’ll own Python systems that are business-critical, highly visible, and used daily by traders, risk and operations teams.

Why this role stands out

• Real ownership of systems that directly impact trading and risk
• Exposure to PnL, reconciliation, market data and transaction workflows at scale
• Strong engineering culture, you’re building platforms, not firefighting tickets
• Global environment with high technical standards
• Relocation and visa sponsorship available for the right profile

What they’re looking for

• Strong Python experience in production environments
• Hands-on with Pandas, NumPy, Linux, and backend services
• Experience building robust, data-critical systems (financial or similar domains)
• Comfortable working with ambiguous requirements and evolving problems
• Background in trading, financial services, or other high-reliability systems is important

This is a great fit for engineers who enjoy owning systems end-to-end and want to work on problems where correctness really matters.
