Linux SRE - Production Trading Systems

About the role

A Tier One proprietary trading firm in Sydney is hiring an SRE to own its production trading environment. This is a hands-on production role close to the trading desk, focused on the performance, reliability and operability of large-scale trading systems and exchange connectivity.

Key responsibilities

• Monitor and troubleshoot live systems, and build and maintain the operational toolkit: configuration management, process management, deployment, monitoring and data collection and analysis.
• Work directly with traders to communicate changes, manage incidents and resolve problems in real time.
• Work with Risk Management, Operational Trading Support and Clearing to coordinate production changes, assess their operational risk and reconcile trade and position breaks.
• Mentor and cross-train other SREs and help define how production runs.

Required profile

• 5+ years in an operations-focused engineering role such as SRE, DevOps, Linux Systems Engineering or Network Engineering.
• Rigorous, detail-oriented, with genuine ownership of production and urgent response when it matters; shared on-call, so reliable availability is essential.
• Experience running real production Linux systems where latency, uptime and correctness mattered; cloud-native, consultant, contractor or short-tenure profiles are not a fit.
• Trading-firm, exchange or market-data experience is a strong advantage.

Required skills

• Strong Python and shell scripting, with at least 3 years of hands-on use.
• Deep Linux knowledge: kernel internals, scheduling, network and system configuration, performance tuning.
• Solid networking fundamentals: routing, multicast, VLAN tagging, LLDP and Ethernet.
• C++ familiarity is useful but not required.

What we offer

• Market-leading compensation as base salary plus bonus, all in cash, with no diluted equity.
• Unlimited technology budget for hardware and tooling.
• Flat, technical organisation with no politics.
• Full relocation and visa sponsorship available, with particular interest in Australian expats coming back to Sydney.
