Trading Systems Reliability Engineer

A leading high frequency proprietary trading firm is looking for a Trading Systems Reliability Engineer to join its core engineering team in Sydney. This is a high-impact, business-critical role with strong front-office alignment, working directly on the systems that underpin global trading operations. The firm is open to relocation and visa sponsorship for strong international candidates.

Why this role stands out:

• Ownership of trading infrastructure supporting low-latency order entry and market data systems
• C++ is core to the role — you’ll be expected to design and optimise systems with performance in mind
• Exposure to a broad range of asset classes across global markets
• Work closely with developers, traders, and quants in a fast-paced, collaborative environment
• Tackle complex technical challenges with a focus on automation, scalability, and uptime
• Flat team structure, modern tooling, and strong internal engineering culture

You’ll bring:

• Strong, hands-on proficiency in Python and C++ would be ideal
• Background in site reliability engineering or performance-critical systems
• Understanding of system architecture, monitoring, and automation
• Commercial mindset and experience solving production issues in high-availability environments
• Buy-side or low-latency trading experience is a strong plus, but not required

This is an outstanding opportunity for an engineer who thrives on responsibility, business impact, and technical depth — all within a supportive, forward-thinking team that values expertise and innovation.
