Support Engineer - APAC Risk, Treasury & Post-Trade
OptiverAbout the Role
Optiver's APAC Risk, Treasury and Post-Trade IT team in Sydney builds and runs the systems used to measure and control risk exposure, fund trading, and process trades after execution. The platforms sit at the end of a chain of internal services, exchanges, brokers and clearers, and are relied upon daily by traders, risk managers and middle-office staff across APAC offices.
- Own day-to-day production support for the risk, treasury and post-trade platforms, investigating incidents from first alert through root cause and shipping straightforward fixes.
- Work with stakeholders to establish the real impact of issues and keep them informed through resolution.
- Reduce the support burden by automating manual workflows, removing recurring failure modes and improving alerting, monitoring and diagnostics.
- Extend AI-assisted operational tooling for triage, investigation and remediation.
- Manage the technical operation of the production environment, including capacity planning, process and host layout, and deployments across more than 1,000 application instances.
Requirements
- 2+ years operating and supporting production software systems, ideally where failure has direct financial or operational consequence
- Debug systematically, following a problem through logs, data and configuration to its root cause rather than its nearest workaround; wants to fix it in the code, not around it
- Strong Linux fundamentals and the confidence to investigate directly on the machine: processes, memory, file systems, networking
- Fluent in a scripting language, most usefully Python, with the instinct to automate a task the second time it has to be done
- Comfortable with data: competent SQL, and enough numerical curiosity to tell a wrong answer from a right one
- Interested in AI and keen to leverage it in day-to-day work, but checks its work
- Communicates clearly with non-technical stakeholders under time pressure
- Additional experience we value: a solid understanding of the trade lifecycle: clearing, settlement, margin, corporate actions, position and P&L reconciliation
- Additional experience we value: experience with observability tooling, CI/CD pipelines and configuration management across a large estate
- Additional experience we value: experience using LLM or agentic tooling to do operational work
